On the day of the testing, the room used was at a constant 21°c. The system used comprised of the following components:
• Intel core i7 920
• Asus P6T OC Deluxe Palm
• 6gb of Corsair Dominator Ram
• BFG 295GTX
• BeQuiet 1200w psu
• Arctic Cooling MX-2 TIM
To keep the test fair, each heatsink was fitted and tested 3 times, for idle and load temps. The heatsink was cleaned between installs using Akasa’s Tim Clean. The PC was allowed to idle once booted into windows for 15 minutes, before the idle temps were recorded. To simulate full load, Prime was ran on all 4 cores for a full 20 minutes before load temps were recorded. The results were then calculated using the average.
I used Arctic Cooling’s MX-2 as my TIM of choice, as I believe it’s an excellent paste to work with. Easy to remove and re-apply when needed. For Temperature measurement I used core temp 0.99.5 beta and Prime 95 25.9 was used to load all cores on the CPU.
Shall we take a look at the test results...?
The results of the idle test show us that the Nexus XiR-3500 beats the stock Intel cooler by a good 6°. The Vendetta II beats the XiR-3500 by 1° although XiR-3500 was a lot quieter. Things are looking good so far for the Nexus XiR-3500.
As you can see from the above chart, the Intel Stock Cooler is barely up to the job of keeping the i7 920 cool. It was also making a right racket while it was at it.
The OCZ Vendetta II while doing a very good job and being a lot quieter then the Intel Cooler was also still keeping up its whine.
Onto the Nexus, what can I say? It’s within 3°c of the OCZ Vendetta II but, here’s the killer. It’s almost silent. The cooler really does do what it says on the tin!! For a silent cooler, to turn in results like that it’s brilliant.
I was that impressed with how well the Nexus coped with the temperatures, I decided to see how far I could clock my i7 920 with it. Now I’m a water cooled guy and I know my chip is stable up to 4.2 GHz using 1.4v under water at very good temps.
I decided to see how the Nexus would cope with a bit of clocking.
