It is very easy to install a heatsink with a pushpin design onto a motherboard. Below I will take you through the steps I took to do this process.
The system I am installing the heatsink in consists of an Intel i5 750 in a ASUS P7P55D-Deluxe motherboard. The first thing I did which was installing the mounting brackets and made sure the screws were securely in place. Here is a picture of what it looks like with the mounting brackets are in place when they are installed on the heatsink.
The next step in the process was to apply the Thermaltake thermal paste onto the processor. After application of the thermal paste on the CPU, I used an old plastic card to spread the paste evenly on top of the processor.
After applying the thermal paste I seated the heatsink, aligned the holes up and pushed the push tabs through to lock the heatsink into place on the motherboard. Upon locking it into place I plugged in the four pin PWM connector into the motherboard.
After everything is all said and done, here is what the heatsink looks like on the motherboard. Included is also what it looks like after the motherboard with the heatsink attached to it is put into place in the computer case.
