Default How hot does your GTX 260 runs?

Just for comparison, my 4870 (default clocks) was running at 59C full load (2-3 hours of gaming).

My newly aquired EVGA GTX 260 SSC (default clocks) reached 70C full load with fan speed at 40%....
My E8500 at stock speeds gets to 43C under full load, so the case has good cooling.

So is 70C normal for GTX 260s? Ive had 2 crashes to desktop with this card, while playing games... (pc running at stock speeds)...

That temperature is just fine. It is probably something else that is causing problems.

Did you uninstall your ATI drivers properly before you installed the GTX260? You need to uninstall the drivers, then run Driver Cleaner Pro in Safe Mode to get all the gunk out. Then you can install the Nvidia drivers.

Also, maybe run a RAM test to see if you get any errors.

mm.. why are you running full load at 40%?
crank that up to at least 60-70.. sacrifise some noise for better cooling? imo its worth it and your card won't die as fast

Stock speeds, stock fan settings: both my 260s are running in the 70s. They run hotter than the 280s I had.

Thanks for the feedback. So looks like 70C temps for these cards is normal.

Yep both my Gtx 260 SC and core 16 run about the same around 68-72

This is true to a certain extent, however, based up on my experience with both the 260's and 280's, the tolerance for Temps may very likely decrease as the Overclock is increased. That is to say that if one Card does not "crash to Desktop" at Stock speeds at 70 c, it deosn't mean all Cards will react the same...some Cards may exhibit Artifacts or CTD at low Temps, say 70c with high OC's. It can get somewhat finicky and experimental finding a decent max OC while maintaining Temps and stability.
Also, just because your Card is maintaining good Temps and stability while playing FC2, does not necessarily mean it will react the same while playing Crysis. I found if you can keep Temps low and OC's high and be stable in Crysis, you will be fine in just about any platform you throw at the Card.

This I find quite strange as my 260 FTW ran about 10c COOLER than my 280's...odd!

Good point and I really don't understand why folks run these Cards at Stock Fan speeds...a little noise from Fans is no big deal, particularly when playing games through either headphones or Surround Speakers. I never run my 280's at Stock Fan speeds, I have 3 Profiles that I use (very easy to set-up in Precision) and load upon starting Windows:
1. 50% for 2 D mode - keeps idle temps at about 38c
2. 75% for all gaming - keeps temps from getting above 65c
3. 85% for Crysis and Warhead - keeps temp from ever getting above 70c
Note that SLI set-up does generate a bit more heat than standard, particularly with the #1 Card

As for your crashing to Desktop, could be a num,ber of things:
1. Unstable OC of CPU due to your Memory / FSB ratio (linked / unlinked / synched etc)
2. Unstable GPU due to combination of OC and heat - to eliminate this try underclocking your SSC Card, in some cases a Factory OC could be the culprit.
3. As mentioned, could be a Driver issue

I updated my BIOS to the lates and suddenly was suffering from the odd "crash" in games and have narrowed it down to my CPU OC, in particular my Memory to FSB ratio. I simply downclocked my CPU and since has been fine...too busy right now to go through the whole process of experimenting with Memory Ratios and Voltages,,running Prime etc etc..friggin time consuming.

70c is nothing.

I don't remember what my GTX 260's temps were, but nVidia has their drivers set to basically alter fan speed to keep the GTX 280s around 80-85C under load...

Please note my previous Post....70 to 85 may not be "nothing", but it all depends (on various Cards) as to OC. Imo, I don't want my 280's running that warm (85c), thats it extremely warm and close to the normal top-end operational Temp!!
I certainly wouldn't rely on "Drivers" to Auto adjust my Fan Speeds when playing games like Crysis or Warhead....why? The Cards are worth as much as $500 a piece, I find a little care n attention should be par for the norm.
