    hey everyone, this is my first time applying thermal paste but I am having trouble identifying which part to apply on. Here is a picture of all the parts that the heatsink connects to:

    Here are my guess:

    This is my gpu:

    This is my cpu:

    This is my northbridge?

    What is this? (the 2 boxes that says R36W) These are connected by thick pads to the heatsink.

    As you can see, on the northbridge, the thing is broken. Should i rip it off and replace it with paste? I have read posts that says the original thing is better for the northbridge.
    also, please identify the 2 boxes and if i should put paste there as well.

    Thank you. :)

    I would only recommend thermal paste for the CPU and graphics processor. The sticky thermal pads should be fine for the northbridge and whatever those other things are. My heatsink doesn't even cover those.

    The two little blocks are ferrite cores. The top part is your CPU. The middle part is your northbridge. The right part is your GPU.

    The northbridge thermal pad looks like it could use a replacement. You can find one for cheap on eBay. Replace the thermal paste on your CPU. Make sure you clean the die thoroughly first before you apply new paste. If your GPU came with a thermal pad, it would be okay to reuse the pad if it is not ripped up like the northbridge thermal pad. If it uses thermal paste, replace that as well. You do not need to put anything on the ferrite cores.

    Yes, you may replace the thermal pad with a copper sheet with thermal paste. Putting paste alone won't close the gap between the heatsink and the northbridge die.
