Reeven Justice (RC-1204) CPU Cooler Review

by - 6 years ago




Reeven are still a fairly new company based in Asia that focus on cooling products and also fan controllers. It’s hard to find any Reeven products in the UK as they don’t seem to have any resellers over here, which is a real shame. The products really do look very nice and I think there is certainly a place for them here. It’s been a while since we have had any products from Reeven, almost 2 years, so it’s great to finally get some more to put on our bench and see how the company is evolving and expanding. We have been sent 3 of the latest coolers to come from them and we are going to look at the first one, the Reeven Justice, today.

The Justice is a mid-tier single tower CPU cooler made for 120mm fans. As you can see from the box the actual unit looks very nice, there are 6 heat pipes to take away the heat from the CPU to the tower and you also can get a sneak peak of the fan attachment clips which we will take a closer look at later. Also on the box you can see that the Reeven Justice will fit all of the popular Intel and AMD sockets.



Inside the box, which incidentally is very well packaged, we get this beauty of a cooler. The 120mm black and yellow fan is pre-attached and there is no need to remove it during installation so it is pretty much ready to go straight from the box.

Also in the box we have everything that is needed to attach the cooler to the motherboard and an instruction manual to help you along. There are also 4 more yellow clips, these are to allow you to add a second 120mm fan to the cooler using the nifty little attachment system if you wish. The clips just fit into the holes where the screws would normally go, then simply push onto the cooling tower. As well as all the fittings they actually give you a small spanner too. Now this is something you will need if you don’t have access to a long screwdriver, which will become more apparent shortly.


Here you can see the clips that I mention above a little better, such a simple idea and they work very well. As you can see, the fans are black with yellow blades and details, this is something that we see a lot with Reeven. They have obviously chosen these colours as their brand colours and stuck with them. They do look very nice, however they will struggle to fit many colour schemes which could put people off buying them. The fans have a max RPM of 1500 and a max static pressure of 0.067inchH2O.


Going back to the cooler we can see that there are six heat pipes leading away from the CPU contact plate. This should help disperse the heat more effectively as it allows it to travel away from the CPU and into the tower where it can be moved on by the fan. Again, the contact plate really does have a quality finish and looks superb.

Speaking of it looking superb, this is just eye pure eye candy. It’s not often that a cooler makes me think “wow” but with the Reeven products they have this amazing brushed aluminium finish which just looks amazing. It just oozes quality. Even the branding fits in with the design, which is something that isn’t always easy to do.


Fitting the cooler wasn’t as easy as I had hoped. It wasn’t hard by any stretch of the imagination, but there were certainly areas that could be improved. For instance, I use a long 15cm screwdriver which fits into my trusty ratchet driver which gives it an extra 6 or 7cm. Even with this I wasn’t able to screw the cooler down properly as my ratchet driver is a little too thick to get into the holes that are provided, I had to use the spanner which is provided instead. This did make things a little trickier as you can only do quarter turns with the spanner. This is something that shouldn’t be a problem at all. There are 2 ways to solve it instantly, first, they could lower the overall profile of the cooler, as it stands, it is quite tall. Even easier, they could make the holes a little wider. The main issue was that the larger part of my screwdriver (which is a standard ratchet driver that I see used regularly when building computers) was simply too wide for the small holes that are available to use; as said though, this isn’t a deal breaker. They do give you the tools to let you combat the issue and when it is fitted it does look superb.


As you can see, low profile RAM has to be used if you want the fan on the same side as the fan. This could cause issues if you are using RAM such as Corsair Dominator or similar. It’s also the same story if you were to buy a second 120mm fan for this cooler, you would be limited to low profile ram. This is always something you should consider when buying a CPU cooler. On most boards, only using 1 fan is perfectly fine with any RAM as you can just put the fan on the opposite side of your ram slots. In this picture you can also see my last little problem with this cooler, the gap between the fan and the tower. Due to the tool-less fan clips there is a rather large gap. This could mean that the air is escaping around the sides of the tower rather than going through the fins and doing its job. This could cause problems when testing, but we will see how it handles that later.

Test System and Methodology

We always use the same test system and tests with CPU coolers that we compare against each other. The full specifications of our test system are as follows:

Test system:

  • ASUS P8Z77-V, LGA 1155 socket, Z77 chipset
  • Intel Core i5 3570K with Gelid GC Extreme under the IHS
  • 16gb HyperX Genesis 1600 MHz ram
  • Antec High Current Gamer 620W
  • Cooler Master Test Bench v1.0

We’d like to say a big thank you to ASUS, Antec, Kingston, Cooler Master and Intel for providing components that makes this testing possible.

Testing Methodology:

  • We always use Gelid GC Extreme thermal paste to make sure testing reveals the efficiency of the tested coolers not the efficiency of the bundled thermal paste.
  • Prime 95 is run for 10 minutes and then the average maximum temperatures as recorded by CPUID HWMonitor are noted
  • The average temperature across the four cores is taken on our quad-core processor
  • Fans are mostly left to operate at default PWM profile speeds and with maximum fan speed for reference. If PWM functions are not supported then fixed fan speeds are used and sometimes a low noise adapter if appropriate/provided. If fixed fan speeds or low noise adapters are used it will be clearly pointed out either on the graphs or in the write-up.
  • All default result entries on graphs are for PWM performance unless otherwise specified. A variety of fan speed results are done for a particular product review and then removed from the graphs in future reviews of other products to avoid clutter. If you would like to see more fan speed results for a particular product please check its individual review.
  • For water cooling tests all pumps have been operated at 12 volts directly from the power supply
  • Delta temperatures are always used (Observed temperature minus ambient temperature) and we keep the ambient at 22 (+/- 1) degrees for all testing. Delta temperatures should correct for any marginal ambient differences between 21-23 degrees.
  • Acoustic measurements are taken 10cm horizontally away from the CPU cooler with the VGA fan disabled, hard drive in idle and power supply isolated. These are taken at desktop idle and Prime95 load.
  • The cooling performance tests are run at stock 3.4GHz (with Intel Turbo up to 3.8GHz) and overclocked 4.5GHz (1.35v) settings. Voltages are fixed to prevent inaccuracy between comparisons.
  • All other coolers in the graphs have been tested under identical settings so are fully comparable.
  • Each test is repeated 3 times with 3 remounts for consistency of results
  • There is approximately a 1 degree Celsius margin of error in our temperature recording software CPUID HW Monitor
  • There is approximately a 1.5dBA margin of error with our Benetech GM1351 decibel meter

So, the Reeven Justice certainly looks the part, but how does it perform? Hopefully very well, I really want to see these products hit the UK market as they would complement some PC builds easily. At stock the single tower, single fan cooler does sit close to the bottom of our table with a temperature of 37c delta under heavy load. Even though that it is near the bottom of the table, if we look at some of the other coolers we can see why. We do have a lot of AIO units, dual 120mm fan coolers and dual tower coolers so it is to be expected somewhat.

When we overclock the CPU the Reeven Justice actually climbed up the table a number of spaces. This shows that the cooler does do a good job when the fan speed is increased. I do wonder if this cooler struggles a little bit due to the gap between the tower and the fan. I believe making this smaller would decrease the amount of air getting lost and increase the efficiency.

Acoustic wise, we see that it does very well. At stock we get a reading of just 39Db which is in line with the Dark Rock Pro 3 as well as a lot of other coolers that are produced mainly for silence.

When overclocked the fan does get a little louder, and drops down the table a little. Under heavy load we see a reading of 44db. This is perfectly quiet enough though, the noise was not something that was hard to ignore, it was just a nice little purr.

Final Thoughts


The Reeven Justice, as mentioned, is hard to get hold of in the UK. I would love to see this change however. The RRP comes in at just over £30 for this unit. I certainly think this is quite a lot of cooler for £30 so is worth the price tag. It looks great and although the performance isn’t the best it is certainly able to do its job.


As soon as I opened the box to the Reeven Justice CPU Cooler, I could tell that the design and quality of the product was very good. It has a lovely brushed aluminium finish and a very nice looking fan. There are some little issues that I think could be addressed to make it perform better, such as reducing the gap between the fan and the tower. Installation could be a little easier also, my screwdriver is typical to what a lot of computer builders use and I did struggle to have enough length to screw the cooler down, even with the extension. This could be solved with slightly wider holes or by reducing the height of the cooler. They do give you a spanner that does help a little, but even then it’s a bit tricky. As you can probably tell, I do have a little bit of a soft spot for the Reeven Justice.

I think it doesn’t particularly over exceed in the cooling department, nor is the quietest, but for someone who is happy with a mid-range cooler, with amazing looks, I think this would be the cooler to get.

Unfortunately, despite my love for the aesthetics of this cooler, it doesn’t quite fit into any award categories. I do have two other Reeven products to test, so we will see how they do very soon!


  • Excellent build quality
  • Excellent aesthetics
  • Quiet


  • Can be a little tricky to install
  • Fan could be closer to the tower to increase performance

“The Reeven Justice is a mid-range single tower 120mm cooler that looks like it should be a high-end cooler. If you want something that looks amazing, and performs satisfactory then this is a cooler to consider. I hope these make it across the water to the UK soon. “

Thank you Reeven fo providing us with this sample.
