Radeon HD 4890 Thermal Paste Question

post #1 of 5
Thread Starter 


The chip on the 4890 is a bit exposed and does not have a full cover plate over it.

What is the best place to apply the paste?

Should I spread it over the chip and transistors surrounding the chip, just the chip, or over the whole ting?

I don't want to create needless places for air to get tramped and therefore heat up.

JUST over the chip part. There is no need nor use to cover the little resistors and capacitors. In fact, if you use some kind of thermal paste that is capacitive at all it can cause shorts.

Oh and you don't need to smooth it over the chip, just a dot or a tiny X pattern would be plenty.

Temps are better than I remember using this method. My Accelero TWIN TURBO Pro wasn't getting a very good spread when I took it it off today to apply TX-4.
