Testing and Installation


Test Rig

To install this cooler I am going to be using the usual AMD rig with which you should be familiar, but the more observant of you will notice a slight change in the setup due to the fact that the old motherboard just wasn’t up to the task of being abused so regularly.  The good news about this though is that now you get overclocking results aswell. I should also note that the processor is also new.

The installation of this cooler wasn’t as easy as I though it would be. I was hoping to be able to clip it onto the motherboard and power up, but as usual its never that easy. In the end I had to remove the mounting board with the two clips on. I then had to clip the cooler on and screw the plate back in place. The good thing about this is that it made sure the cooler was perfectly centred on the CPU; the downside of course is that it’s fiddly, and takes a while.



To test CPU Coolers we simply boot the PC into Windows Vista, and measure temperatures under idle and load states. The onboard temperature sensor is disregarded and instead the CPU’s own diode is used.

For idle testing, we simply let the rig sit, doing absolutely nothing for half an hour and take the most representative temperature of the last 10 minutes. The same is used for the load testing, but instead of letting the PC do nothing; we load both cores to 100%.

Ambient temperature was 19 degrees C, side panels were on and fan speeds were at maximum. I used the supplied TX2 thermal paste.

All results have been compared to the Xigmatek HDT-S1283 reviewed previously.
