3-4 times.

But it's never anything too hard that I don't know, I've thought about opening PS3/PS4s and clean them up though the problem is then putting them back and I'm wary of that.

Soldering is something I want to learn as a hobby and maybe someday to use it professionally as it's a very handy skill to have.

I did it for the first time last year, changed thermal paste and cleaned the dust from inside, everything went well
