Setup and test results …
For our test system we used following configuration:
Intel Core i5-4460 @ 3200 MHz with 0.99 Volt
MSI B85M-E45 Rev. 2.0
2x 4GB DDR3-1600
MSI GeForce GTX960 4GB OC
Cooler Master 500W Silent Pro PSU
Fractal Design Define R5 Gehäuse
Windows 7 Ultimate 64 Bit Service Pack 1
For measurement we used following tools: Prime95 V28.7 und SpeedFan V4.51
Thermal grease: Cryorig CP7 (supplied) 8.3 W/mk
The ambient temperature was at 20°C.
For silent mode the fan was fixed to 600rpm, for maximum cooling to 2500rpm. Idle testing was done only running Windows and speedfan. Stress testing was done by using small-FFT test of Prime95. Energy saving features have not been deactivated in BIOS/UEFI for testing.
Cryorig C7 test results …
With this amount of innovation we hoped for some kind of wonder concerning the temperatures. The C7 couldn’t deliver a wonder but let’s be honest, the small-FFTs test generates a steady amount of heat which will only occur for a few seconds during normal PC use. That’s why we use this test for high performance coolers.
To put values into perspective we also used a more everyday kind of benchmark. After setting a custom fan curve for the C7 we ran the popular game ‘Assassin’s Creed: Unity’ for 2 hours. This resulted in core temperatures between 50°C and 60°C and a fan running around the point of being audible.
This point was reached at about 1400rpm in our setup. At maximum speed the 92mm generates an unpleasant frequency but is overall not as loud as anticipated. There were neither grinding or clacking sounds present.
We explained the differences in measuring CPU temperatures and how to overclock in detail in our Intel Core i3, Core i5 and Core i7 OC guide.
