Cooling is an important factor in compact builds such as SFF and 1U rack mounted systems, but it’s something that can be tricky at times. You either get something that isn’t very effective or you get something that is loud.
Gelid has just launched their newest cooler, the Polar, and it is designed for just this. It is a low-profile CPU cooler compatible with Intel’s LGA 1150, 1155, and 1156 sockets. The tiny cooler supports Celeron, Pentium, Core i3, and Core i5 processors with a TDP up to 65W.
The heatsink height is just 27mm, so it will fit almost any chassis and the fan is inserted into it and won’t take up any extra space. Speaking of the fan, it is a 75mm fan and it features an intelligent PWM Fan Control and has an RPM between 1400 and 2000. It is a silent ball bearing fan and it can push an air flow of 29.6/50.3 CFM/CMH.
The width and length are both 92mm so it shouldn’t interfere with any other components such as RAM or PCIe slots, nor power or fan connectors. The noise level is rated between 16 and 28.9 dBa.
It is rated for 50 thousand hours of lifetime and is backed by a five-year warranty. Best of all, the suggested retail price is just $14 USD or €12 Euro.
