Socket 775 is used by Pentium 4, Pentium D and Celeron D processors. The way of fixation is very different from other types of processors. In socket 775 the pins are on the motherboard and not on the processor, that’s why the motherboard officially supports only twenty installation and removal operations. After that, there’s no guarantee that the board will work properly. So, don’t unnecessarily remove your socket 775 processor from the motherboard!

First make sure both surfaces – of processor and cooler - are clean and free from impurities and that the processor is well installed.

Using a small spatula (which can be made out by cutting a piece of the hard transparent plastic from the processor box), apply some thermal grease on the center of the processor. Don’t worry about covering the whole processor area because the cooler pressure will make it uniform.

Next, install the processor cooler, as we’ll show on the next page.
