I just bought a new cpu and tried to fix the rig by myself. but i accidentally remove the thermal paste off the heat sink. i planning to buy thermal paste to put on it. what brand of thermal paste should i buy?
furthermore, must i take the whole motherboard out or i can just take out the heatsink for putting thermal paste. TIA
