Setup & Results

To test the heatsink, we boot into Windows and let the system sit idle for 10 minutes, then measure temperatures. We then load the CPU cores to 100% using Prime95 for 20 minutes and then again measure the temperatures. This entire process is done twice and then averaged to avoid any minor discrepancies that might occur. Ambient temperatures are kept at 25?C, and Arctic Cooling MX-2 is used for the thermal interface material. CoreTemp was used to record all temperatures. Temperatures are reported to the nearest whole degree Celcius; anything less than one degree can be attributed to slight testing variances. Frankly, the tolerances at less than one degree are extremely minute for testing such as this. All throttling features in BIOS are disabled.

Our test setup is as follows:


We decided to pit the HPK-10025EA primarily against other small coolers but we must mention first that the HPK-10025EA is not designed for overclocking; it is designed as a low noise, low profile cooling solution for a compact case. As such, there is no point in overclocking our Core i7 chip because it wouldn’t be a fair comparison. That being said, how does the HPK-10025EA perform? Let’s take a look below.


As we can see, the HPK-10025EA does a good job at keeping the hot i7 920 under control when running at stock speed, virtually equal with the top small coolers at idle, but trailing behind slightly at full load. For a very compact and slim cooler, It would appear that the Evercool HPK-10025EA is very adept and handling a Core i7 at stock speeds.

Normally during the course of our testing for heatsinks we also heavily overclock the CPU in order to test cooling efficiency under extreme load. However, in this case there was really no point in doing that since the HPK-10025EA is not designed for overclocking, and certainly cannot handle the heat output of a juiced-up Core i7 monster. This heatsink is designed for stock speeds, in a very quiet setup, and a compact form. It simply is not designed for enthusiasts and top overclocks.

Regarding noise produced by the fan: the HPK-10025EA’s fan does spin up to the maximum RPMs and there is a very mild hum; It’s not "silent" (being a rather relative term for computers anyways) but is very quiet and we think it would fit perfectly into a smallform case, both in physical size but also in terms of low noise levels.
