Not until I get my voltage regulator heatsinks fitted on, i've had a few crashes already trying to play games.

just a suggestion try using the stock baseplate from the gtx cooler.
i did a similar mod with my old 4870 uding a T-rad2 and the stock base plate, temps were supoib

Update time!
I just had a game of TF2, and the voltage regulators didn't seem to mind not having a heatsink, they sat comfortably at around 85.
The core however didn't go above 48 degrees, even in the middle of battle with 5+ enemies. 84C down to 48C (on 80% fan speed which is in-audible). I'm more than quite impressed tbh
.
Also, that was exactly the temperature it said it would go to, which may just be a coincidence.
Earlier today I ordered some of the Akasa thermal tape, and also some MX-2 because my AS5 has almost run out (with my recently aquired free delivery), so hopefully they will arrive tomorrow or friday and i'll pop them on, then I can try overclocking.

Bump and update with some more temperatures.
HL2 with Cinematic Mod
Maximum Settings
Max Temp: 50°C (that's in demanding areas, and probably because it's pumping out 150-200 FPS most of the time)
Company Of Heroes
DX9, Ultra settings, 16xQ CSAA
Max Temp: 46°C (that's a 1v1, probably a few degrees higher in a team game with more units)
Team Fortress 2
Max settings on everything
Max Temp: 48°C
Idle
Temp: 35°C
My Akasa Tape and MX-2 came today, which i'll install and then run Furmark. It will be quite interesting to know if MX-2 is any better than AS5.
EDIT: I just ran Furmark, and the temperature got to 53°C after 60 seconds before the VDDC temperatures on GPU-Z got to 110°C, at which point I chickened out.

Seems people are really interested in this O.o
Anyway, using the tape on the heatsinks worked great, they now stay on. There is obviously still something wrong with the VRM sink with this cooler because they get to 125°C after a few minutes of Furmark, which is pretty much the same as when they had no heatsink at all! However, this seems to be normal as i'm reading this review and he has similar problems (my core is 10°C cooler than his though
).
For those wanting to know, after 1 minute of furmark, the core temperature was 53°C with MX-2, the same as the AS5, and with no settling time.
Pictures coming soon (somebody post something so i don't have to quadruple post!).
EDIT: Pictures!
This is a picture of the stock cooler, obviously something was wrong as the middle looks different, like it wasn't touching the gpu. Somebody with more experience can tell me what's going on there, it might be why i had high temps with the stock cooler.
This is the Accelero cooler with AS5 which i took off so I could reach the VRM and RAM heatsinks. As you can see, the contact was much better, though the Accelero is a bit smaller than the gpu core so it doesn't completely cover it.
The Accelero heatsink all cleaned up (and an excuse to take a photo of the nice weather)
The RAM heatsinks had a sticky glue which was pretty bad at sticking to stuff, which I had to remove so I could use the Akasa tape. It was stubborn stuff and took about 10 minutes to get it all off, both the heatsinks. I then sanded both of them.
Showing the space between the PCB and the heatsink.
And the finished article.

No, main reason why I got it was to reduce noise. 3 Fans spinning at 1500RPM moves more air and is a lot quieter than one fan spinning at 4000RPM.

Looks very nice, looking forward to seeing how the stock VRM sink works on the card.
I just kept original heatsink and put 2x 92mm fans on and the temps are siilar to accelero xtreme.

Final update!
I attached the VRM cooler from the stock heatsink today, because the one that came with the Accelero was utter trash. Here's how it went.
These are the results from 5 minutes of Furmark with the VRM heatsink that came with the Accelero.
~140°C
The temperatures you're looking at are the bottom 5 temperatures (VDDC #1-5), as you can see they are very hot with the Accelero heatsink, and that is on a cool day, with no overclock. The maximum safe temperature for the VRMs is 150°C I think.
So, following the excellent example of OnBoard and his thread here, I set about using the VRM heatsink that came on the stock cooler.
I had some trouble unscrewing the screws holding the plastic casing to the heatsink, so I hacked through both of them together.
After about 15 minutes on and off hack-sawing I had the part I wanted:
Off came the Accelero for the third time so I could reach the VRMs. Off came the PoS heatsink that came with the Accelero, and after a quick wipe clean for the VRMs, I used some MX-2 (make sure you use non-conductive TIM if you do this) on each of the VRMs.
I had also decided to replace the mediocre backplate supplied with the Accelero with the backplate from the stock cooler, because it gives more support to the PCB, and looks better. I don't know how much better/worse at cooling it is though. So, on went the backplate and on went the VRM sink, both attached by the same screws.
After attaching the Accelero for the 4th time (I was getting quite good at it at this point), I was ready to put it back onto my motherboard.
As you can see, the black backplate makes it look much nicer.
I booted it up, started up Furmark, and these were the results I got:
~110°C
So, it was a lot of work but I think it paid off

I wouldn't say 84C and 57C are similar
Thx
i just compared temps with very first post where accelero in the very same test achieved 92 CI am not native English speaker so sorry for wrong expression, i achieved better temp

That was with the Stock cooler, not the Accelero.Thx
