If I remove the heatsink/fan... Tags: Fan Heatsinks Thermal Compound Components Last response: January 13, 2011 11:19 AM in Components Share sullonone January 11, 2011 11:53:35 AM do I have to take the old thermal paste/pad off or can I just screw it back down? edit for clarification: I took my heatsink/fan off to clean it. Does that ruin the old paste? Do I have to clean it off and reapply or can I just leave it on and reassemble?

Removing the heatsink breaks the thin paste layer which helps improve heat transfer. It introduces air pockets and that acts as a heat insulator rather than a heat conductor. m 0 l Related resources How to Remove SB heatsink/fan - Forum How to remove heatsink/fan from Gateway M305CRV - Forum help!? need to remove xtasy gf4ti4200 heatsink/fan - Forum Heatsink/Fan upgrade w/out mobo removal?? - Forum Problems with removal of the stock i5-2400 heatsink/fan - Forum Can't find your answer ?

You should change the thermal paste\pad every few months, but if you already did in the past few months, you should be good. m 0 l beanoslim January 13, 2011 11:19:57 AM Yes you can re-use pads but not paste, if it has a pad I'd remove it and use paste anyway. You don't need to re-apply paste every few months just when needed, like your cpu temps rise. m 0 l Can't find your answer ? Ask !
