The "I have know idea how thermal paste works" thread.

post #1 of 17
Thread Starter 
So tell me, should all processors have a thermal paste applied? Do all processors come with it if they're prebuilt or taylored by someone? How can I go about applying some, and how much would it cost to buy some for my processor?

I haven't checked to see if mine has any yet because I don't want to screw with the heatsink. If it's of any importance, My brother has had this computer for two and a half years before giving it to me this month.

All computers have thermal compound of some sort. It fills in the cracks in the HS and CPU core/IHS (at a microscopic level, and a more visible level) making it so its all just one surface which greatly increases the ability to transfer heat between the CPU and HS.

Thermal paste is designed to fill up the miniscule gaps in the metal surfaces between the CPU and the heatsink with a thermally conductive material, thus creating a solid thermal conduit from CPU to HS to air.

A lot of prebuilt PC's come with a thermal pad on the heatsink, which is not as good as a liquid paste. Get some good stuff like Arctic Silver 5, shouldn't be more than 5-10 dollars. Clean the heatsink base and the top of the CPU with isopropyl alcohol, let dry, apply a thin layer of AS5, and place and secure the heatsink. AS5 should knock a few degrees off your temps.

EDIT: Everyone always beats me to the punch - *cough* Jori *cough* with my long posts. lol

You both get a rep point, aka cookie, for being such helpful people. Thanks guys!

Guess I gotta head on down to Electronic Futures then These 50+ CPU temps just won't due, and I don't want to have to underclock

What would I get for the 10 or so dollars it costs to buy the AS5? I'm guessing I could do my CPU and my brother's with one purchase. It would be kind of stupid for them to sell just enough to cover one CPU.

*waits for confirmation that, yes indeed - computer technology being the expensive bastard it is - I can only cover once CPU*

There's plenty there to cover probably 10 or 20 CPU's - it'll last you a long time. You don't need that much to cover 1 proc.
