I just got the Arctic Cooling "Accelero Twin Turbo" cooler, which I put in place of the stock cooler for my 4870.
Idle temperatures are horrifically high: 78°C.
I thought I'd give gaming a go to see how it goes, and after 5 minutes the whole computer crashes - the monitor goes to "no signal" mode as well.
Unfortunately I don't know how high temperatures were going, so I don't know if it really did get too hot.
There's something else I need to eliminate, and that is a somewhat underpowered PSU: I've my E8500 running @ 3.8GHz (1.30V BIOS), 3 hard disks, 1 DVD. The PSU is 480W. Today I added another HDD, so that might be the straw that broke the camel's back.

Any ideas/input/things I could try? Is there a program that logs the temperatures, even when the system crashes?
Are the crash symptoms similar to overheating? Is there a safety mechanism that shuts down the card before it gets damaged?

Thanks for your help!

Send the cooler back and put the factory one back on for one. 2....just set fan control in the ati CC to at least 40 percent

Better yet, try setting fan speed in CCC to 65% and see if it cools any better. ALso, were you actually getting worse temps with the stock VGA cooler?

Ok, here's what I did:
Downloaded Riva tuner, manually set the speed to 100%, temperatures down to 45%, a whopping 30% from before! Did some gaming, all fine.
Set the fan speed to 'auto' in Riva tuner - bam! Overheat, reset. Set speed manually to 65%, temps still at 45%, games all fine. Good thing: at 'auto' under desptop apps, fan is inaudible. Bad thing: when I'm gaming, I will have to manually set the speed to 65%, unless someone knows a way how to automate this process, even if it's just a little?
That fan's staying on my card though, because I'm a silence freak, and when I'm not gaming, my PC is now very, very quiet.

Alright, well this is how my CCC looks like:

I can manually change my fan speed there. It saves to the profile I made.
You can also make 2 profiles, like one for gaming and one for browsing the internet (low fan speed).

Also, I suggest you to really buy a better PSU, 450W is simply too low to run a 4870 without any problems.

Don't use rivatuner with CCC......just set your fan under the CCC......your just running 2 programs that can conflict with each other
