Thermal paste problems

[iBeInspire]

Hey all So my HD6850 was idling high, at about 44 degrees, I thought I should have a look at the thermal paste.
It was almost flakey, and having remembered that after 5 years when I took the thermal paste off my OLD athlon 64 3500+ the temps IMPROVED, I tried the same with my GPU.
I boot into windows, and my compy starts making MASSIVE noise, go into afterburner, and on my 2D preset (0.975v), I'm getting 65 degrees x.x
*Suicide*
Is it safe to use in 2D mode @65 oh-C for the next few days, until thermal paste arrives, and which thermal paste to buy?
Thanks all, and feel free to laugh at my insane stupidity

Take it off clean everything, then do it again with decent paste like MX4

when you put it back together make sure everything is done up nice and tight and straight.

I cleaned it perfectly, just didn't reapply any new paste...
I've got one vote for MX4, I guess I'll go amazon it now ~

LOL thats why then!!!!

You have to use paste mate


(read all of the post this time)

Yeah I know, just that I had past experiences with the old athlon, which improved without thermal paste, thought luck would be on my side x.x
Apparently not

Thanks for your input Tommy, any specific way to apply thermal paste to the tiny core on the HD6850..?

Use ketchup until the new paste arrives !!! Rofl !!!

Indeed MX-4 is a good choice !

Like Arctic Silver 5 personally. All of the top TIM's are pretty superb these days though.

Lol at first I kinda thought.. "naaah, surely he didn't put it back on without any TIM"

Then, "ARGH! what are you doing?!" lol

You're lucky you didn't toast it.. it may be damaged by this *hopes not* I wouldn't turn it on until you have paste for it mate.

The old athlons had no shims/caps on them (if you're going that far back) so the heatsink may have just had good contact to the thing and you were lucky. Most stuff these days has a shim/cap to stop the die getting crushed so you need paste to fill the gap which is otherwise filled with air!

The absolute best scenario I find for thermal compound is, less is more. It's literally there to fill microscopic gaps and surface imperfections between the heatsink and top of the thing you're cooling. But new compounds now are so heat conductive that they can be used in droves and not see much difference.

In all seriousness, GET SOME PASTE ON IT!!

LOL, Thanks for all your help <3
I feel halfway retarded, but I hope some of you ay have seen where I was coming from ~

Ordered MX-4 for £5, and It just arrived half an hour ago, applied it and tightened as hard as possible, now it's idling at 36 oh-C, and 76 at the top end.
Still not too happy with temps, may bring my 2D profile down a little more, but at least I can use my PC again, and I've learned a valuable lesson.

Again, thanks to all

It funny you should say that about the athlon, because it DID have a Shim-thingy... It's still going strong in my uncles house, since I gave the whole rig to him when his died... I just stuck the heatsink straight on the metal (After having cleaned it with water), and even after a 15% overclock, It still topped out at 60 oh-C with the stock heatsink/fan...

I guess I had an accumulation of positive Karma at the time

especially after cleaning it with water :lol:
