Starting July 2013, our cooler test setup has transformed. It is now an Intel Core i7-3770K chip paired with an ASRock Z77 OC Formula with the CPU clocked at 4.5GHZ at 1.42V. To reduce the ambient heat around the system, we’ve also removed the discrete GPU and the system is now used on the integrated GPU. Additionally, the PSU is isolated from the system. This is done in order to obtain a higher level of accuracy in our results.
|Processor||Intel Core i7-3770K @ 4.5 GHz|
|Motherboard||ASRock Z77 OC Formula|
|Memory||Kingston HyperX T1 8GB 1600 MHz (9-9-9-24)|
|Storage||Kingston SSDNow V+200 120GB|
|PSU||Xigmatek NRP-MC1002 1000W|
In our new test setup, tests are run at the overclocked configuration only. The stock clock tests are no longer carried out because, well, lets face it, what’s the point of a cooler if you’re not going to overclock?
Temperatures now are reported as delta °C over ambient [Delta °C = Mean Core Temperature – Ambient Temperature]
An overview of the test process:
- Ambient temperature is taken before each run.
- For idle temperature readings, the system is left unattended for 15 minutes before the reading is taken.
- For load temperatures, Prime95 (small FTT) is run for 20 minutes.
- An average of individual core temperatures is taken.
- Each cooler is tested with its fan(s) set to automatic using the PWM controller. If the fan does not support PWM, it is run at 100% speed.
- Noctua NH-T1 thermal paste is used for each cooler.
