Cooling a hot headed 6800 GT...

[Fenuxx]

OK, I have my XFX 6800GT, and it came PRE-OVERCLOCKED (BIOS defaults and all) to 374\535. The card runs at about 57c idle and about 71c load (after HL2 and FarCry, etc). I am wondering what I can do to lower these temps, as they are a bit too high for me (although I have read that these are considered "normal"). I have 2 available options.
1.) Remove the current thermal grease and install some Arctic Silver 5.
2.) Same as above + install the copper heatsink (like the ones EVGA is selling aftermarket).

The problem is, I can't seem to find one of these copper heatsinks online anywhere, (BTW, my current heatsink is Al) and I can't get one from EVGA as my card is XFX; also, I don't think XFX is selling Cu heatsinks (correct me if I'm wrong). If anyone knows where I can get one (for sure), let me know. I DON'T want the NV Silencer 5 as I don't want a 2 slot card. Any help you guys can give is certainly appreciated.

considered water cooling??

No, as I have an Antec Super LANBoy, water cooling wouldn't fit very well anyway, and the temps aren't producing problems (yet) so I won't go to that extreme.

If they're not causing any problems, why void your warranty for some cooling solution that really won't benefit you overall? If the temps are too high for you, just don't look at them.

get an Artic cooling NV silencer5 and put some as5 between them. My x800 was running quite well, topping out around 52c on load with the oc maxing out at about 520/540. I added an ATI silencer with a custom fan mounting nd the temps dropped to about 37c on full oad and my oc went up to 545/565. I love this thing.

As I said, I don't want to have to get the NV Silencer, and although the temps aren't causing any problems yet, they are high enough that it is possible that they might down the road, as I have heard that people with really high CPU temps that stay high for a significant period of time start to have problems. And as I don't plan to do any big upgrades for a while, aside from a CPU and memory upgrade, this will be my basic rig for the forseeable future.

if you dont want an nv5, and there is no point in watercooling, the i would say get the EVGA Cu heatsink with some AS5. if your XFX is reference design, which is probably is, then it will work.
like the guy above said, your cards temps are perfectly fine....if they were any lower then you could be considered lucky. there is no point to void your warenty just to make yourself feel better..
