do i need new thermal grease?

[Weenus]

I bought a new mobo and im gonna put my old cpu on the mobo, its an athlon 64 3200+.

Do i need to buy some new thermal grease/goo or can i use whats already on there?

And if i need to buy new stuff do i scrape the old stuff off the heatsink / cpu?

Yes, I'd recommend scraping off the old layer and applying a new, thin layer of thermal compound.

You should clean the old paste off the cpu and heatsink and apply new thermal paste.

Clean the old stuff off with alcohol and apply the new paste.

If it was a thermal pad, it'll be impossible to remove it with alcohol.

But not with a hairdryer. Be careful though.

I never had any trouble removing a thermal pad with alcohol.

You can save yourself a bit of scrubbing if you use something plastic to scrape away the excess before you apply the alcohol though.

Make sure you use a lint-free cloth to do the final wiping. I hear a coffee filter works well.

Yes get a new thermal paste, preferring the Artic Silver 5. But before that, you can use 70-90 % Isoproply alcohol (rubbing alcohol) to take out the glunk(left over paste) for both CPU and Heat sink with a cotton swab or a cutip. It worked for me
