Scythe Launches GlideStream 120 PWM SC Fan

Scythe’s GlideStream series has just received a brand new member named GlideStream 120 PWM SC, which incorporates the company’s well-known features as well as a brand new 3-way limited switch. Featuring a small hub and large blades design that ensures increased airflow at low fan speeds, this should be a good cooling solution for those of you who appreciate a quiet rig, especially since it also comes with PWM support. The 3-step switch is definitely its most important feature, as it allows the user to limit the fan speed to either 800, 1.150 or 1.500 RPM. The GlideStream 120 PWM SC is incredibly silent on the first setting, in which in runs from 300 to 800 RPM.

There are other things that make this fan noteworthy, though, including a set of insulating rubber mounters that reduce vibrations transferred from the fan to the case, as well as a grooved blade design that minimizes air resistance. Other highlights include installation holes without tunnels, which support an easy installation process, and a 3-pin to 4-pin adapter. The Scythe GlideStream 120 PWM SC fan features an MSRP of just €7,50, which is rather affordable considering its unique perks.

What fans do you have installed in your case right now? Are they as good as the new GlideStream?

Report Suggests High Pressure CPU Coolers Can Damage Skylake Processors

Intel’s latest architecture requires a new LGA 1151 socket and features an enhanced pin count. Additionally, the CPUs are built on a 14nm manufacturing process. Some of you might remember that Skylake retail samples do not ship with a stock heatsink which raised concerns about temperatures. Thankfully, Skylake is very efficient with improved thermal dissipation. Here we can see the difference in size between Intel’s official Skylake heatsink and the previous generation.

However, according to, CPU coolers exhibiting high pressure mounts could damage the 1151 socket and Skylake CPUs. One theory suggests this is due to Skylake’s reduced thickness which makes the CPU flex under pressure due to a lack of mechanical stability. Therefore, any cooler which adopts a hefty clamping force is capable of pushing the CPU into the socket and damaging both the motherboard and CPU pins.

This is clearly a very worrying turn of events, and PCGamesHardware contacted a number of cooler manufacturers to see clarification. Here’s is a complete rundown of the replies:


“The company Scythe EU GmbH announces that on several coolers from its portfolio, a change of the mounting system for Skylake / plinth is made ​​1151stAll coolers are in fact generally compatible with Skylake sockets, but it can in some cases result in damage to CPU and motherboard when the PC is exposed to stronger shocks (eg shipping or relocation). To prevent this, the pressure was reduced by an adjustment of the screw set. We will send the new set of screws you also like to charge. Please send your request via email or use the contact form on our website(”


“Our SecuFirm2 mounting systems are subjected to prior to the release of new platforms an extensive compatibility testing. It could be determined with reference to the Intel LGA1151 platform (“Skylake”) no problems. Also on the part of our customers and our specialist resellers and system integration partners we have no reports of any problems. Our SecuFirm2 mounting systems access (with the exception of some more compact models of the L-series) for generating the necessary contact pressure on coil springs back, which allow a certain degree of flexibility both in terms of tolerances in the height as well as the case of vibrations or other forces. Compared with conventional spring-less installation systems where pressure is produced exclusively by the deformation of the mounting brackets, so can reduce the mechanical load on the CPU, and motherboard socket and any damage can be prevented by excessive force.”


“All EK Water Blocks EK-Supremacy Series CPU Water Blocks – Including the latest -MX and -EVO variants – are fully Complying with Intel Socket imposed H3 (LGA-1151) Mechanical force limitation. The clamping force, created by our PreciseMount spring loaded mounting mechanism, is well within the allowed mechanical limitations. The design of PreciseMount itself Prevents over-tightening and damage to mechnical Possible Either socket or the CPU packaging.

Older generation of (physically) compatible LGA-1151 Water Blocks with classic, undefined clamping ForceType mouting mechanism such as Supreme LTX – requires special attention When attaching the water block. As a result the use of search Waterblocks is not recommended with the LGA-1151 socket CPUs.”

Today, we received a statement from ARCTIC about their CPU cooler range and the effect it has on Skylake CPUs and 1151 motherboards:


“With this official statement we would like to assure that ARCTIC coolers are not affected by these problems and thus fully Skylake compatible. All ARCTIC CPU Coolers complies concerning the released sockets with the mechanical specification from Intel. With our coolers there are no problems on Intel CPUs of the 6th generation (Skylake) for LGA 1151. Depending on the parcel service drop heights of over 2 m can not be excluded. Therefore we recommend regardless of the CPU used to carefully evaluate the dispatch and the packaging used and to possibly mount larger and heavier CPU coolers by the end user.”

While this is far from ideal and illustrates a major flaw in Intel’s production, cooler manufacturers should be able to complete thorough testing and judge the probability of damage occurring. Thankfully, many have released statements pretty quickly, and it remains to be seen how much force is actually needed to cause damage. Currently, it seems like the issue is only effecting coolers with a very heavy mount point. As a result, there’s no need to panic but this is something which needs clarification from Intel and further research.

Do you use a hefty air cooler or water cooling setup?

Scythe Releases Fuma Twin-Tower CPU Cooler

Scythe released a new cooler with a twin tower design which in itself isn’t anything new, but the new Fuma Twin-Tower CPU cooler comes with a few things that set it apart from other twin tower CPU coolers already on the market. The Fuma is able to deliver a great cooling performance and allows for setups to fit your system and needs with its fan position abilities.

With a height of just 149mm its highly compatible and should fit into most PC chassis’, and I don’t think we’ve had a twin tower cooler that low before. Most of them are above the 150mm which can create clearance issues in narrow chassis’. As the Scythe Fuma allows you mount a fan on either side as well as one in the middle, it also allows you to mount a total of three fans should you have enough clearance next to the CPU socket. I don’t know how much extra cooling a third fan would give, probably not much, but you have the option if you want to do it – maybe just for aesthetic reasons.

The Scythe Fuma comes with two Scythe Slip Stream 120mm PWM fans with 300 up to 1.400 RPM and there is a third set of fan clips included right away should you want to add a third. It has 6 copper heat pipes with 6-millimeter diameter and Scythe has soldered the heat pipes to the solid copper baseplate and the small cooler-block to increase contact area and maximize the heat transfer. Both copper heat pipes and copper-base-plate have been nickel-plated in a final step.

The Fuma weights a total of 920 grams with two fans, which isn’t as much as some other ones, but it’s still quite a bit of weight. It is compatible with pretty much any CPU platform thanks to the including mounting system.

The Scythe Fuma (SCFM-1000) CPU Cooler is available now for a suggested retail price of €39.00 plus taxes.

Scythe Announces Third Version of Grand Kama Cross CPU Cooler

Scythe have been hard at work on their somewhat unique looking Grand Kama Cross CPU cooler and the third revision of the cooler is available now. The previous Kama Cross CPU cooler was efficient and delivered a great performance, but it doesn’t compare to the new version.

Scythe’s engineers have redesigned all the vital aspects of the CPU cooler and created a great looking new cooler that promises some great performance thanks to refined processes. We already see the changes on the base plate and heat pipes, which both could be considered the main part of a CPU cooler. The main two heat pipes have been upgraded from 6mm to 8mm and the manufacturing process has been improved to allow a better transfer between the heat pipes and base plate. Both the base plate and heat pipes are full copper and are completely nickel-plated.

The next place where Scythe improved the cooler is on the actual fin design. The engineers have re-designed the two aluminum-fins blocks and fitted the fins with a special sawtooth tread design. The new design lowers both the operating noise at higher fan speed ranges as well as the air resistance.

Scythe added a 140 mm axial-fan from their GlideStream series to the new version. The larger size and added PWM support again helps to provide a better cooling at a lower noise levels. It can push between 29,90 and 97,18 CFM at noise levels from 12.5 to 30.7 dBA. The PWM is step-less in the full range from 400 to 1300 RPM.

Scythe packed everything into the Grand Kama Cross 3 that you’ll need to mount it, including tools. It is compatible with Intel’s LGA 115x sockets as well as LGA 775, 1366, and 2011(v3). Full AMD compatibility is assured too as they haven’t changed the cooler mount system since the AM2 socket.

The Scythe Grand Kama Cross 3 is available now and best of all, it isn’t even expensive. You can get the Grand Kama Cross 3 (Model: SCGKC-3000) for a suggested retail price of just €36.50.

Scythe Releases Slip Stream 120 DB Fan Series

Scythe expanded their 120mm fan portfolio with a new series, the Slip Stream 120 DB. While the naming isn’t the smartest as most will associate the DB with dB, it has nothing to do with the noise generation but rather the double ball bearings used.

The new line-up includes five regular models with fixed fan speeds as well as one PWM-enabled model and thanks to the new dual ball bearings the fans have an increased lifespan of 350,000 hours.

The Slip Stream series feature a small hub and large blades to increase the flow area and airflow without increasing the fan speed. The PWM enabled version offers a wide fan speed range from 300RPM to 1300 RPM. The five non-PWM models will be available with an RPM of 500, 800, 1200, 1600 and 1900.

The model name may make these fans sound like some noisy ones, but they aren’t. The 500RPM model operates at just 7.2 dBA while still providing a steady airflow of 24.50 CFM while the 800RPM model can move 40.17 CFM at just 10.7 dBA.

Scythe also supplies four rubber vibration dampeners to assure that any vibration is absorbed and doesn’t move onto your chassis. Regular fan screws are also included and so is a 3-pin to 4-pin adapter.

The long life Slip Stream 120 DB fans are available as of today with the MSRP of 7.50 EUR (excl. Tax/VAT) for regular models. Slip Stream 120 DB PWM can be purchased for 10.00 EUR (excl. Tax/VAT).

Scythe Introduces Ninja 4 CPU Cooler

Cooling expert Scythe announces the official successor of Ninja 3 Rev. B CPU Cooler; the Ninja 4. It comes with some major technical innovations, mainly the increased cooling performance while incredibly shaving 180grams off the product weight.

“Ninja 4 stays true to the core concept of the Ninja series, by keeping focus on passive and semi-passive cooling capabilities of the tower-cooler. To further underline this core concept, a new fan with additional features has been introduced. The GlideStream 120 PWM fan has been equipped with a special fan controller, allowing users to switch between three different fan speed ranges. Low mode has been tuned for extremely silent operation, where PWM control range varies from 300 to 800 RPM at virtually inaudible noise levels from 4,0 to 12,5 dBA. Medium mode suits most user purposes, as it covers a wider range from 300 to 1,150 RPM and offers the best performance to silence ratio. The last mode has been implemented for users seeking more performance, since it offers the maximum fan speed range starting at 300 and ending at 1,500 RPM. Supplied GlideStream 120 PWM fan has great influence on the Ninja 4 design in addition, thanks to its grey fan blades and black fan-frame.

Scythe has made modifications to the structural design of the Ninja 4, where total of six 6-mm copper heatpipes are aligned in one layer inside the copper base-plate. Both the base-plate and heatpipes have been nickel-plated in addition. Thanks to this setup and further adjustments, total weight has successfully been reduced by 175 grams to 905 grams, while increasing the overall performance at the same time. Users seeking further improvement of performance or silence are able to mount another 120 mm case fan thanks to the second supplied set of fan clips.

Ninja 4 utilizes the back-plate based Hyper Precision Mounting System (H.P.M.S) for firm mounting and easy installation procedure. The socket compatibility list features AM2, AM2+, AM3, AM3+, FM1, FM2 and FM2+ from AMD as well as sockets LGA775, LGA1150, LGA1155, LGA1156, LGA1366, LGA2011 and 2011-v3 from Intel. All mounting clips, one screwdriver, two sets of fan clips as well as thermal grease and a manual are supplied with the Ninja 4 CPU Cooler.”

The Scythe Ninja 4 is available as of today with a MSRP of 37.50€ ex. TAX.

Kotetsu CPU Cooler Released by Scythe

With the announcement of the new Kotetsu CPU Cooler, Japanese cooling expert Scythe is going forth to offer a 120 mm tower model with an aggressive pricing and great cost/performance ratio.

With the Kotetsu CPU Cooler, Scythe is able to prove that great performance does not necessarily require the heatsink to be very heavy. Kotetsu is equipped with four high-quality six millimeter copper heatpipes, an optimized aluminum fin-structure and an all-copper base-plate, yet puts up a weight of merely 480 grams.

Fast dissipation of heat from the fins is managed by the pre-mounted 120 mm Glide Steam axial fan, which rotates in a range between 400 and 1.400 rpm thanks to the PWM-support. The noise level varies between inaudible 5,3 dBa to still very silent 28,0 dBA. Although being very silent, supplied Glide Stream axial fan is able to move from 63,49 to 165,10 cubic meter per hour, respectively 20,7 to 79,0 cubic feet per minute. Similar to other Scythe CPU Cooler models, Kotetsu can also be equipped with an addition case fan, to create a Push-Pull constellation.

Another great feature of the new Kotetsu CPU Cooler is its compact size of 130 x 58 x 160 mm (W x H x D). Hence allows it to be used even for gaming systems based on Mini-ATX and Micro-ATX form-factor. Such systems have usually high restriction when it comes to the height and size of the built-in components. Scythe utilized the „H.P.M.S.” mounting system in addition, to assure an easy and fast mounting procedure.

Compatibility to a big variety of sockets is yet another specialty of Scythe. The Kotetsu CPU Cooler supports the Intel sockets LGA1150, LGA775, LGA1155, LGA1156 and LGA1366 as well as AMD sockets AM2, AM2+, AM3, AM3+, FM1 and FM2. All required mounting clips for the screw-based mounting system, alongside one wrench and thermal grease, are supplied as well.

Scythe Kotetsu CPU Cooler is available at a price of $38 / €28 / £23.

Scythe Release Grand Kama Cross 2 Top Flow CPU Cooler

You rarely see anything exciting or new in the top down cooler space but Scythe’s Grand Kama Cross 2 certainly changes that. This is the second incarnation of Grand Kama Cross series and is based on the same uniquely shaped heat sink design. The X structure also allows the bulk of the heatsink mass to be located in the centre and the upward sloping edges mean RAM compatibility and motherboard compatibility is greatly improved. The heatsink has four copper heatpipes that appear to be 6mm. These feed into two separated heatsink blocks which are both ventilated by a downward flowing 140mm Scythe Glide Stream fan. The fan ranges between 37.18CFM/13dBA to 97.18CFM/30.7dBA supporting PWM between 500 and 1300 RPM.

Interestingly the fan sits on its own frame which is secured to the capped heatpipes. The fan comes with an anti-vibration rubber frame design. The mounting system is Scythe’s “Hyper Precision Mounting System” (H.P.M.S.) supporting all the latest Intel and AMD sockets (including LGA 2011, FM1/2, AM3 and LGA 115X). The heatsink measures in at 175,2 x 140 x 140 mm (W x H x D), 2mm less than its predecessor and the weight is 760 grams, 10 grams more than its predecessor.

The Scythe Grand Kama 2 will retail for €30.50 excluding taxes.

Scythe Ashura CPU Cooler Review

In my opinion Scythe are one of the top brands for air cooling, yet they are one of the most unsung brands in the entire industry because they don’t have the aggressive and well funded marketing departments that other companies do. Furthermore, they primarily focus on the Asian market having a huge presence in Japan. Though their presence in Europe is still pretty big. For those who don’t remember last year Scythe USA was actually shut down due to financial troubles and are still in the process of making a comeback while Scythe Japan and Europe are holding up warranties for Scythe USA products.

We’ve only reviewed a few Scythe products in our time including the Scythe Mugen 3 which is one of my personal favourite CPU coolers of all time in terms of bang for buck. That said the Scythe’s Ashura has a lot to live up to for me. So without any further ado let us proceed through this review and find out how good the brand new Scythe Ashura is. If you’re interested you can check some specifications below:

Scythe Big Shuriken 2 Rev.B Low Profile CPU Cooler Review

Scythe’s Big Shuriken series has been the CPU cooler of choice for a lot of system builders who are opting for small form factor systems or HTPCs and need a low profile yet high performance CPU cooler. Scythe’s original Big Shuriken was incredibly popular and so Scythe responded with the Big Shuriken 2 which adds another heat pipe and support for the X79 LGA 2011 platform. Today we are taking a look at this new Big Shuriken 2 from Scythe and seeing how it stacks up against other low profile CPU coolers. Measuring in at just 58mm high the main selling point of the Big Shuriken 2 is its height but Scythe are also looking to push the performance side of things with five 6mm heatpipes.

For those who are interested we’ve got some detailed specifications for you to see below but without any further ado let us proceed with the rest of the review.

Scythe Introduce Mugen 4 CPU Cooler

Ever since I first reviewed the Scythe Mugen 3, nearly 200 days ago now, I was truly impressed with its impressive performance for such a small price. In fact to date, I’d go as far to say it is probably the best CPU cooler on the market at its (£40) price point. With that in mind it is incredibly exciting to be able to tell you that Scythe have now come out with their Mugen 4 CPU cooler, the next incarnation of the incredibly popular Mugen series. 

Japan has been the first market to get the new Scythe Mugen 4, SCMG-4000, which builds on the design of its predecessor the Mugen 3. It features what Scythe are calling TMAPS (three-dimensional multiple airflow pass-through structure) which is essentially an unorthodox fin arrangement that improves the airflow and therefore cooling performance of the CPU cooler. 

Scythe have also updated the mounting mechanism with their HPMS (hyper-precision mounting system) which is essentially a new retention module that takes fewer steps to install compared to the previous model. Having reviewed the previous model I can tell you it certainly was fiddly and challenging to install, although it did give an extremely firm high-pressure mount. The Scythe Mugen 4 will support Intel’s upcoming Haswell LGA 1150 processors.

The Scythe Mugen 4 retains the six 6mm heat pipes but they are capped slightly differently to the Mugen 3. The base is nickel plated copper and a Falcon 120mm PWM fan is the active cooling component of choice with a 400 to 1400RPM range pushing 20.7 to 79CFM. Measuring 130 x 88 x 160 mm, the cooler weighs about 625 g. Release is expected for April the 24th and it is priced at 4,980¥, US $50 or £40 like its predecessor.
