anyone use thermal paste on their motors/heatsinks?

[blueb8llz]

it is used to keep temps cooler. i am using it on my motor and heatsink. i read that if applied wrong, it can actaully lead to higher temps! i didnt come with instructions, any of you guys know how to correctly apply thermal paste on the heatsink/motor?

Thermal paste (I like MK-2), between the motor and heatsink will help. It's just a bit messy to clean up when you switch motors, ect.

Just don't use thermal adhesive LOL. I put enough paste on the inside of my clamp on sink to squish out when I put it in place, then I wipe off the excess. The point is to fill any air gaps or surface irregularities so the heat will transfer better and more evenly.

hmm..someone else told me to only use very little paste. like only razor thin.
what tool should i use to apply it and should i put paste on the clamp or the motor?

The layer of thermal paste should end up only razor thin. It's a good conductor, but not as good as the heat sink itself. Most thermal paste comes in either a squeez tube (like toothpaste) or a syringe (spelling?). Just put a dab inside the sink and use your finger to spread it around (it washes off easy). It should bridge any gap between the sink and the motor.

the thickness of the compound will depend on how well the surfaces mate, and how well polished they are. If the finish is rough, there is more irregularity in the surface, and it will take more paste to fill the gaps. If you polish the motor and the sink, you can use less. Ideally the less you use the better, but only if it's an adequate amount to ensure consistent contact between surfaces.
