I compared the OCZ Vendetta with the stock Intel cooler. Ambient room temperatures during testing were 72F. Idle temperatures were taken after the computer had set idle for 30 minutes with only Windows applications running in the background. Load temps were taken after 15 minutes of running the Processor Arithmetic section of SiSoft Sandra's Burn-in application. Both coolers were tested using fresh Arctic Silver 5. In my experience, I have always had temps drop at least 3C and usually more after the AS5 goes through the 200-hour curing period, so keep that in mind when you see the temps I got during testing.
I have a fan controller that will accommodate 4-pin PWM fans, but I decided to leave the fan speed up to the Intel drivers, as they always seem to keep my CPU fan turning at the best RPMs for noise vs airflow.
First test was at stock clock speed of 2.2gHz. Next I tested load temps on both coolers. The Stock cooler temp bounced around quite a bit, but that is pretty common right after applying AS5.
Next I overclocked the CPU to 2.7gHz. Getting idle temp is a little different as the Intel drivers run the processor at low speed while at idle by dropping the CPU multiplier to 6. So instead of being totally at idle, I ran folding @ home, which puts the CPU at about 20% load.
Finally, I overclocked the CPU to 2.862gHz. Being quite satisfied that the Vendetta performs well, I ended my testing here.
