wow! 20 degree drop

[nageov3t]

I got my CPU temps to drop from 70 C to 50 C this afternoon I added two extra fans (previously I only had 2 case fans in there), and I cleaned some of the thermal grease off the cpu.

ever since moving into the new apartment, my temps have been crazy high -- that's what I get for losing central air, though considering the apartment itself sits in the mid-80's (F), 50 C seems acceptable.

What do you mean by "Cleaning off some of the Thermal Paste"? I've been trying to drop the temps of my system into the mid 30's idle, and even just 10 degrees would help that. I recently put arctic silver 5 on the die, but I didn't exactly clean any of the old stuff off, should I have?

Umm, yes. You should always clean off old thermal compounds/pads before putting on new ones.

th reason for this is now the AS5 is only conducting heat from the old thermal paste to the heatsink, you will get less perfomance ths way than if you just had the old stuff on. teh heatsink shoiuld be cleaned and the cpu shouldboth be nearly if not completely spotless hwen you add new thermal pase.

What's the best way to remove the old paste? I read somewhere nail polish remover, is that safe?

 

[alexXx]

rubbing alcohol.

Before you go cleaning it off, did you have any thermal paste on there in the first place? If you just had the stock cooler on there and then changed to something better and added AS5 then, there would've been no paste to clean off...

Rubbing alchohol should work fine. If it's some sort of adhesive, you might need some acetone free nail polish remover. That would only be for a thermal pad or something though.

plus there was way too much on there. I must have been drunk or forgettful when I put the box together, but it looked like there was almost an entire tube of arctic silver pumped out onto the cpu

If you use nail polish remover, then you'll have to clean it off with alcohol. Nail polish remover has fragrance oils, gelatin -all kinds of crap that has no business being between your HS and cpu.

Get the 99% pure alcohol. Gotta ask behind the counter for it. It's not usually out on the shelf

 

[M16Grenadier]

Regular 70% no good?

 

[Squirtle632]

Your local pharmacy has 91%. That is the lowest I would use. Fry's has 99% and 32oz is about $8 US.

You have to ask yourself, if I use 70% alcohol, what is in the other 30%?? Most likely nothin I'd want on my BIG buck processor

Good idea yeah? Prolly, but its not going to a life and death difference. There may not be a difference at all, if you?re just re-applying the same compound or very similar all you?re going to do is take compound off and replace it the exact same thing, what would be the benefit of that?

The old stuff is dry and used. It won't fill the valleys in the silicon and heatsink as well as fresh wet stuff will.

and cause the new wet stuff to be displaced where it shouldn't be going

Dry and used?, quality compound shouldn't dry out (should it?). I'll agree that getting exess compound off the the HS/F and CPU is a good idea but getting it spotlessly clean shoudn't really have a performance impact.
