CPU Heatsink Results Database

Over the past years we have tested a few hundred kilos worth of heatsinks; in order to give you quick access to the massive amount of data we have entered all the test results (more than 400) into a database, grouped by test setup.

We’ll start with the oldest test setups and move our way on the next pages up the latest tests. If you want to jump straight away to the latest Intel S775 and AMD S754 results use the menu below:

The HD got a clean install of Windows 98SE powered with the latest Asus PCProbe utility. Each contestant will be faced with the same CPU being clocked at 2 different speed , being:






The CPU will be heated up by running a little program called Prime95. Both the time to get to the hotest point as the time it takes to return to the idle temp are recorded.

The system was not installed in a case so the displayed temps in the results might be lower then the ones you might get. We are comparing 2 heatsinks so the difference in temperature is what we are looking for! Each heatsink is equipped with it´s default fan it is delivered with, to give you an idea of how the "out of the box" product performs.
