Hey guys back with another noob question lol. So I bought 99% alcohol to clean thermal paste off my cpu before my new heatsink gets here. Seems to be two small dots on the back of the cpu is it safe to use a coffee filter & alcohol to get it off?

Thanks guys!

I would try using Electronic Contact Cleaner for that.
I would spray it on and see if it dissolves the paste without having to touch it.
If spraying it a few times doesn't work then I would spray it again and very carefully wipe it with a paper coffee filter.

I knew I was forgetting something. You're right - I first used the alcohol, but then I applied DeoxIT and DeoxIT Gold.


At work, I might've just used alcohol, since I didn't have deoxIT there. I'm 90% sure I also cleaned that side of a couple CPUs, there.

very carefully wipe it with a paper coffee filter.
Eh, you don't need to be too precious. Just make sure not to use too much force. Worst case scenario would be the paper/cloth catches the edge of one of the contacts, or you wipe it too hard with something too abrasive and remove some of the gold plating. I'm not really sure about the legitimacy of the latter concern, but gold is soft and the plating is very thin.

I wasn't all that careful, since it was an old i3. And, yet, it still worked fine.

Thanks for the info! I appreciate it!
 
I've also cleaned the side of the CPU that makes contact with the pins. You can be actually pretty rough with that side of the CPU as long as you only touch the gold pins. It looks delicate but it's really not something you absolutely have to be super careful with. CPU's are actually fairly durable. They can take a lot of abuse and still work. Though I wouldn't recommend abusing something you might have paid a lot of money for. I'm just telling you you don't have to be super careful with it to ease your mind.
