As was mentioned in the previous category, setting this heatsink up was beautifully simple, although it WILL require removal of your motherboard. It was just a matter of dropping the heatsink on and screwing it down once the bracket was in however, and after plugging the fan in, we were good to go. Now, unfortunately, we were hoping that performance would have been as good as the setup was easy - too bad this wasn't the case here. For our Overclocking tests (of air cooling at least) we utilize two levels of heat output, at stock and when overclocked. Stock constitutes the processor at 200x15 with 1.425V and Overclock constitutes 233x15 with 1.5V. While we know this processor can go higher, we're not exactly comfortable about giving it more voltage when load temperatures already tap the sensor out at 80 Celsius.
Our testing methodology is as follows - we take four separate measurements to show different load levels for the processor: We have a no load 15 minute period as our idle, 30 minutes of Folding @ Home to show a low priority load, 10 Loops of SiSoft Sandra's Burn in wizard to demonstrate a high priority load, and a standard S&M processor test loop to demonstrate a critical load. Our test bed consists of the following:
- NVIDIA C19 CRB Motherboard
- Intel Pentium 4 530J
- 2x512MB Modules of PC2-5300 Crucial Ballistix
- Ultra 600W PSU
- Onboard Temperature Sensors
- Open Air Test Bench
As we can see, the Evercool sink really doesn't perform much better than the Intel model at all, perhaps a 1-2 degree difference at load, but once the torch turns on, those differences go up in smoke. This is more than likely due to the all aluminum design and frosted base hindering thermal transfer.
