Raijintek Ereboss CPU Air Cooler Review

Performance and Conclusion

The Raijintek Ereboss installed

Intel Core i7-3960X
ASRock X79 Extreme9
4x2GB Geil DDR3-2133
Radeon 7970 GHz
Corsair AX1200 PSU
Corsair Force GT SSD (OS)
Razer BlackWidow Ultimate Keyboard
Roccat Kone[+] Mouse
SteelSeries 7H Headset

For our tests we record the temperatures produced by the coolers when our system is idle and fully loaded. The load was applied by Prime 95 and temperatures are measured using Realtemp and AIDA64 to access the CPU’s various Digital Thermal Sensors.

Fan control was disabled in the motherboard BIOS and the Intel CPU is running at its stock speed/voltage to start with. Room temperature was 23°C. The test is then repeated with the CPU at 1.45v and overclocked to 5GHz.



As normal we are comparing this new cooler with the stock Intel model and a competing model, in this case the Noctua U12S.

So looking at the results from the Ereboss we see that it significantly improves on the thermal performance of the stock Intel air cooler. We also see better results from the Raijintek unit than the Noctua U12s. That Noctua cooler is a touch quieter though, but also significantly more expensive. When we look at adding a second fan to the Ereboss we see a small drop in temperatures which is repeated at 5.0GHz.

Overall we were pleased with the design and build quality of the Ereboss. There were no notable defects or concerns with the cooler and installation was quick and easy. We might have goe with thumbscrews to bolt down the crossbar, removing the need for a long screwdriver and our particular sample was a little skimpy on the thermal paste but no real concerns.

Raijintek’s slim profile fan certainly stands out from the competition and while at 100% RPM it is a touch louder than some of the competition at 95% and below it offers own noise cooling. Thermal performance was also good which was great to see considering the ultra-competitive price of the cooler. In fact this is the real stand out aspect of the Ereboss, its price to performance ratio is hard to match.
