Program Suite
Real Temp – Maximum temperature analysis
LinX 0.6.4 – Applies thorough stress test to CPU
CPU-Z – Confirmation of CPU frequency/voltage
AIDA64 Extreme Edition – Confirmation of temperatures/fan speeds

Testing methodology

Testing will be based on temperatures recorded by Real Temp after 20 passes of LinX stress test. The maximum absolute temperatures will be recorded after the test and averaged over the 6 cores. The delta is then calculated by subtracting the ambient temperature recorded near the intake fans from the average temperature calculated. Tests are conducted with the Intel i7 3930K at its default 3.6GHz stock speed and overclocked to 4.6GHz @ 1.42V. The tests are done inside the Corsair Carbide 500R chassis to simulate real world conditions. To keep the tests standardised we are using Noctua's NT-H1 thermal paste on all coolers.

CPU coolers are reviewed as they come out of the box – with their factory cooling fans, as the manufacturer intended and as the consumer expects.

Additional tests include a passive test where the cooling fans are taken away from the heatsink and a comparison between the cooler used with stock thermal paste against our Noctua NT-H1 paste.

A kind thank you to Noctua for supplying us with NT-H1 thermal compound.
