New system (A8N-SLI + FX55) - Can temps be correct?

[Lifted]

Got my new system from ABS yesterday (had to order complete system - from work) and I've been testing it's limits. The config is

A8N-SLI Deluxe
FX55
2 x 6800GT
2 x 512MB Corsair PC3200XL
Lian-Li VC1000

Yesterday i tried to OC to 2.8GHz by bumping up the FSB from 100 to 107 (214?). Seemed to work, but Prime95 crashed after a couple hours so I bumped back down to stock speeds and Prime ran all night and day. Tonight I bumped it back up to 2.8 by bumping up the multiplier from 13 to 14. Seems stable, ran Prime95 for a half hour or so, but I will run it all night again to make sure before trying further.

Here comes the question. The CPU idles at 35 and gets to 54 when running Prime95, never higher. I thought this was odd so I downloaded CPU Burn-in, but I get the same results of 54C at full load for 10 mins. Is this normal for an FX55, overclocked to 2.8, default voltage, using what I assume are the stock heatsink and fan? If these temps are as low as I think they are, how high can I get this CPU? Is it worth getting a better heatsink and fan to see if I can really crank it up? How high can I crank this and still be safe with regards to temp? 65C, 70C, higher?

Not too long ago I tested some servers at work running dual 2.66 Xeons, and CPU Burn-in would send those suckers through the roof! (I think ~75C, maybe higher) Those are dual 1U systems, and I'm running a single CPU in a case with lots of ventilation, but still! If the Opterons run this cool, they should make excellent CPU's for dual 1U systems.

ur temps are perfectly fine. the cpu can handle up to 70C. 55C load is not bad at all really.

I made a mistake. When I changed the multiplier it didn't stick, so the above mentioned results are at stock speeds. When I got the OC to stick at 2.8, The temp went up to ~63C using Prime95 and ~67C using CPU Burn-in. Prime95 actually reported errors after 30 seconds or so running at 2.8 with just a multiplier OC, FSB was stock. I brought it back down to stock speed since it's fast enough as it is with SLI up and running. If I ever feel the need to bump it up a notch in the future, I'll get some better cooling and see if I get Prime95 to run without any errors. I currently get around 16,000 in 3dmark 03, which I think is about right for my rig.

16,000 in 03? 1024/768 no aa no af?

I'm getting 18,646 at stock speeds: http://service.futuremark.com/compare?2k3=3515672
and I only have a 3500, and corsair value select at cl3.
otoh, I am running bfg 6800gt's, which come factory oc'd to 370 instead of the reference 350.

Thanks for the tip. I had installed the 7120 drivers, but now that I went back to 6693 I am getting 18,853. I owe you one!

Any recommendations for coolers for the FX55. I'd like to get back up to 2.8 or higher, but it runs to hot at the moment to keep it there safely. I'd like something which isn't too loud if at all possible.
