Yeah lol

I'll do that then if it doesn't come with a thermal pad, but how do I know if it has a thermal pad or not

MX2 should be fine... although Gir has quite a bit of experience backing him, I would just like to ask why he feels that pads are a better solution than MX2 as MX2 has a much higher thermal conductivity? Not attempting to be sarcastic, asking a serious question with hope I might learn something I am overlooking...

A pad will be a large.. well.. pad stuck to the bottom (contact surface) of the heatsink. It will have a pull-off plastic cover to protect the pad from getting foreign particles in it. If its bare metal, and an adhesive pad isnt included with the packaging, then you got shafted on a pad.

Maybe it's because the PWN is so small that it'd be too difficult to apply a small enough amount of thermal paste?
IDK I'm completely guessing here...

definately use thermal paste

Use a thermal pad, it should come with them if not use your stocks pads.

If it's thermal tape, you'll feel it being sticky on the back of the heatsink. Look all around the package for a thermal pad just in case they include it in a separate bag. If you'll give me a second, I'll post pics of the thermal pads that came with my D-Tek Unisink. They came in a separate bag within the box, that's why I suggested looking around to make sure.

The thermal pads are usually reddish brown/purple and pretty thin. They'll look similar to mine here.

MX2 should be fine since it is non-conductive, but VRM/Mosfets are so small, that it's incredibly easy to mess up and end up caking thermal paste onto the PCB. Thermal pads are just a much safer method.

yay my guess was pretty right, it was to do with the size of the VRM

Thanks for the quick helpful posts guys, I just hope I don't kill my GPU while I'm installing this heatsink tomorrow

Sometimes they dont have pads or tim, they stress to you to clean off your old pads residue and peel the clear backing off the vrm heatsinks and just apply them as is.
This explains that:

This page hear explains what i think is your model and is as is.

SO i wouldnt use any pads or interface material.
Just clean off the chips and peel the backing off the heatsinks and just apply with slight pressure.

Makes sense. Thanks for clearing that one up Gir

That's what the thermal pads should look like if they include them.
