It is good to install new thermal paste every few years. Clean the old stuff off with rubbing alcohol and reapply some good paste, such as Arctic Silver 5.
Just want to be sure. I'm thinking of cleaning up the CPU and heatsink and reapplying thermal paste, since it's almost 5 years old (or does it not really need to be "refreshed" like this?).
Thanks.
Yes you can, just draw with the four screws until you can't draw anymore. Then pull the screws after eachother out of your mobo, then you should be able to lift off.
To bring it back on, just do it the other way.
I have some Arctic Silver, also from five years ago. Is it still good?
