Hmm... okay. stant1rm, are you sure about the 28 idle? That seems way lower than I've seen. After cooling it off for a bit on 100% CPU fan, I've got it on 38 package (hottest core is at 38).
So I've got Vengeance RAM, which blocks a good quarter of the fan. I'll raise it up as you said, and it'll give me an excuse to reapply thermal paste. I can do all of this in the case, right?
I saw amuffin's thermal paste thread. Just alcohol to clean it off, right?
To the first part of that, when my room temps are actually cool, my 2500K idles at ~27-28C, so yeah, it's doable.
Second, yes, you can do all of that in the case.
And third, yep, just normal rubbing alcohol (Isopropyl), is all you need for that (along with something that won't create a lot of lint when you're cleaning).
