Replace heat sink back on the card

Cross fingers.

Or do this:

Save up 50-60 bucks and get a Musashi. Freaking awesome cooler. When I had my 4770 OC to 915/1000 (flashed to Asus TOP bios and stock was 750/800) with the stock cooler running 100%, I hit 94C load and climbing. When I put the Musashi on there and w/ IC7 I was hitting 55C and stable (even after an hour of furmark set my max screen res and max MSAA + Post processing). Even with the fans turned down low I was hitting 60C. Idle at max was 28C and with fans on low it was 30C.

I did exactly what you said to do. I used basically half a can on the fins.

Well what are you using to stress the GPU for load because if you are using OCCT like you mentioned in a post before dont. My 4870 load at 60-70 in games and it goes over 100C with OCCT cause its garbage. As for stock cooler i thinks its fine for a 4850. When i had my 4850 used to get 93C under load and the i changed paste and it drooped at 89c and this was with 1.3v and 800Mhz. Stock it would have been around 65-70C

No, I didn't use OCCT gpu tool, I used Furmark for the after results and ATItool for the before results. (ATI tool refused to work after working like 2 times so I said W/e).

Stock cooler is ok but nothing to rave upon haha.

Furmark causes artificial load conditions, higher than the card will ever see in gaming.

That was the source of the 4870 popping VRM's/overheating debacle.

Use something like 3Dmark and log temps with rivatuner, that will give you a much better idea. The 4850 stock cooler should load at 75-85C in real world gaming.

Mine temps were in furmark and OCCT <.< In game I when i had my 4770 I never saw my card go over 50C

I'm not saying furmark is bad, just that it stresses the cards more than the manufacturer ever intended. That's why ATI eventually released a patched driver that throttled back the amount of stress that Furmark puts on the GPU, but even with that it still loads quite heavily.

It's a great way to stress test if you have the cooling but I'm not a big supporter of running Furmark on cards with stock cooling.
