I was just playing Mirrors edge, and then the pc went judgery, then completely shut down. Upon rebooting, i checked the temps of the cpu+motherboard and they were fine, but my graphics card was very high. It said 94C before dropping to 77C and its very slowly now decreasing in temp. I have a nzxt hush (2x 120mm fans) and an external blower right beneath the case. If i monitor the temps more thoroughy and show the graphics card is dangerously overheating (with adequate cooling) will this warrant a return on warranty?.. I havnt been overly bothered about temps before, although i dont appreciate having something that warm inside the case, but surely if its making the pc turn off, then its just getting to silly temperatures... BTW i had the fan speed set on a manual 89%. I'l put it up to 99% during testing... its an asus card so i have 3 yrs warranty from last year ....

-Idleing at 69C at 100% fan

I would give the card a clean.

Mine needs a good blast with compressed air every so often as the (stock) cooler
does get clogged.

I have mine idling at about 47C in this weather.
 
Is yours the flat cooler design ( the original ones?) with the fan at 99% and a brief play on mirrors edge the card was at 107C when i quit and checked in CCC... I'l check for dust etc, although i have a dust filter on the front of the case, and the case isnt very dusty at all
 
The original "thin" 4850s run very hot and the stock fan is fairly poor. Try dusting the fan off (if there is any) and see what happens.
 
^ This. I had a problem with my stock ASUS 4850 which was really loud and hot it really drove me up the wall, i tried to replace the cooler but that failed. I then replaced it with a 4850 Golden Sample which is quiet and cool and overclocked already out the box ;)
 
My 4850 is dieing as well hits silly heats, cleaned it re did the thermal paste and it still crashs my sysetm.

5850 Time I think :)

Yes original cooler.

Even with dustfilters my card gets very clogged along the "fins" that come
off the fan.

I can knock a good 10-20 degrees off when cleaned.

Alternativley you could try one of these:http://www.overclockers.co.uk/showproduct.php?prodid=HS-047-AK&groupid=701&catid=57&subcat=787

I'm assuming yours is one of the original reference designs.
 
My 4850 ran hot. I can't remember the exact figures but it was quite high. It never gave me any problems though.
 
The original 4850s are stupidly hot.

Mine started crashing and artifaxing after about 14 months. Cleaned it but temps would still get into the 100`s. Luckily this was when the volt moddable 5850s were available for about £200 (and a quick trip to the high street consumer electrical buyers got me £75 for the 4850 :D ). Now the card runs at max 68`c even @ 1000/1250.

ATI 4850 : Great cards at a great price when released but flawed but cost cutting on cooling etc
 
If you've got the space in your case just change the stock cooler for an Accelero S1 with a 120mm fan. Silent Mine idles at 33 in winter, 40 in summer and I've not seen it go over 60 load yet.
 
Even overclocked my 4850 never runs very hot. In this weather I get mid 60s on Crysis (overclocked, no set fan speed)

I've seen lots of people say the 4850s run hot, is it just the original ones? I have a dual slot Sapphire one.
 
Yes, I believe it was the original versions. The dual slot ones tend to run quite a bit cooler, which doesn't make sense to me. I would have thought the thin / streamlined earlier ones would, at least going by appearances.
