Time to mod my 8500's cooling...

All this talk of epoxy and copper caps has got me excited.

Background:Right now I have the stock HSF epoxied on with Alumina. Anything over 290 will lock up, that means I need more cooling right?

I'm thinking that if I get rid of the fan and epoxy another heatsink right in the center of the stock heatsink that this might improve the cooling? I can then add that fan or something better on top of it.

Any other ideas short of adding one of my spare fans underneath the card?

*Oh yeah, someone here has a small heatsink on the opposite side of the GPU. I'd like more information on that if possible. Thanks.*

Well, its finished! I was stuck at 292.5 core last night, but I know this card is undervolted on both the RAM and core so I'll try playing with that next.
Stock cooling minus the fan. Modded shot profile. Modded shot overheard. Modded shot perspective. Potential heatsink zone.

If you can't tell what I've done:
1. Epoxied(using Alumina) a hacked up Pentium 1 heatsink in place of the fan.
2. Added the fan on top of the new heatsink.

So how about a heatsink on the back of the GPU? I would make it so the heatsink does not touch anything. Seems weird to me plugging all those little holes, but if it works then I might just go for it.:)

Dammit...Ravenshield is artifacting big time...guess its the poor fan location. If you think about it, its essentially being passively cooled since the fan doesn't push enough CFMs to be effective at that distance.

Dammit...:mad:

Slap a good ol tornado 92 mm on there :D

LOL. Did I inspire you speedstream? Keep at it, try and fit a AMD Stock CPU cooler on there. :)

No, just reminded me that there was room to improve upon with my cooling.:D

Here's the problem...I epoxied the stock HS on a while ago...so, this new addition is permanent as well. Time for a better fan I guess. I've already done it once before with some toothpicks...ah well, you'll see it sometime soon!

How about that HS on the back of the GPU???

Well, I got the fan modded on there with some toothpicks and hot glue.:) I ran Nature about ten times at 297 core and it did dandy.:) This was after the pencil trick so I am running a bit more voltage than most.

With the extra voltage, the back of the GPU gets much hotter. Anyone done this or know someone who has?

I just got my brother an 8500 for his d*ll and it won't do over 260/250 bah!

We need to start a sharky RvS Clan...and I need to get rid of this dial-up conn.

Try the pencil trick. It is incredibly easy and works. The last time I tried it with the RAM it didn't increase my o/c, so I may have hit a wall. The core, however, is experiencing the same problems it did at a lower clock speed and voltage so I may do it again to try and get 300MHZ out of the core.:) I'll need that heatsink on the back of the GPU though. Just wish someone could refresh my memory about it!

Another thing, the core speeds help more than the RAM on ATI cards and stock cooling is fine for a pretty high core speed on this card. You might want to try either upgrading the cooling altogther or just reusing the stock after getting rid of that god-aweful epoxy that they use. Doning that got me to 290 with zero artifacts.
