Evercool K803-925CA Heatsink - Results
(Page 4 of 5 )
One of the first things I noticed about the 925CA is that the fan is very quiet while inside my case. Running the fan at full speed in an open system is considerably quieter than most fans. If you have a completely silent setup, fans can sometimes prove to be a distraction.
Using my processor’s on die temperature monitor, I plan to measure the temperatures with my highly overclocked 2.7 GHz processor. I will run the system until it reaches a stable idle temperature, then a peak load temperature while running Prime 95 (a commonly used processor torture test to utilize maximum processor usage therefore producing maximum thermal load).
Test Bed
- 3000+ Venice @ 9x300HTT 1.68v mod
- ASUS A8N SLI 1.6v chipset
- 2x512MB Geil Ultra X PC3200 @ 245 MHz 2225 3.4v
- Albatron PCX5750 @647/749Mhz 1.7v/2.95v

As the thermal load increases on the heatsink, temperatures quickly rise towards 70C, the maximum operating temperature of Athlon 64 processors. Mind you this is highly overclocked processor with a lot of voltage. Your results should be lower. The Freezer and MCW are there for comparison purposes.
The 925CA doesn’t cool the system as much as I’d hoped under load, which can be mostly blamed on my overclocked test bed. The rough bas of the heatsink may play a role, but the amount of voltage being sent to the processor heats things up a lot. Temperatures can easily be improved by lapping the base and adjusting settings on your motherboard. The user can certainly improve overall performance of the heatsink by simply removing the imperfections left behind from the initial lapping process. As for my voltage issue, upgrading my motherboard is the only way to decrease the voltage now that it has been modified.
