4870x2 - Very Hot and loud

Been getting problems with my 4870x2 as of late. Im not sure when it started happening, It either started happening, when i upgraded to an i7 processor, or when my previous PSU (Corsair 750) blew up. (now using antec cp-850)

On Desktop using manual fan control, at 45% my 4870x2 is at , 54deg which is normal as far as i tell. but if i ever launch a 3d game, the primary gpu gets very hot, and within a 60seconds it will be at 95deg, Which triggers the card to automaticly adjust my fan speed to 100%, And is very very loud. even with all my case fans on high, it doesent seem to change it, (with them and 4870x2 its like being in Serveroom) I tried underclocking it to 505mhz, but didnt seem to make much differnce to the tempreture.

Im wondering if its a software or hardware causing the problem i remember some friends saying a driver problem was causing it, and should i use my warranty?

If you know any good applications i can use to show my test gpu etc tell me and il post the screenshots.

System Specs:
Operating System : windows 7 r1100
Graphics driver : 9.6 Catalyst
Motherboard : gigabyte GA-3X58-UD34 (rev 1.0)
Case Antec 1200

What games are you playing that get the card that hot that quick ? If it is a game like L4D then you have a problem....if it is crysis, stalker clear sky or empire total war then it is completely normal. If you want to get rid of the 100% fan jolts the only way I found how to do that was to install an accelero Xtreme 4870X2, good luck.

Well did some more testing with game, if i play AA3 , it does it within 30seconds of loading onto a server, if i play team fortress 2 it takes like 5 mins to start, and would only be at 100% for about 15 seconds, then goes back to normal speed with WoW it would do it in about 5 minuits and last 60 seconds and is usually around 92deg.

If i turn Manual fan control off, CCC ramps up the cpu to about 89% to try and cool the card down.

but i have a friend with same card, and case only he has an AMD cpu, and he doesent get these problems, and i never used to get them either. going to try and warranty the card.

I run my own one at 35% at desktop and up it to 40% for most games and the fan doesn't engage.

Only game I have needed more than that is trine, which requires 45-50%.

Due to my chilly room at 16C(windy day) my idle is 44C although usually sits at 50-53C

Am I right in thinking your ambient(room) temp is quite high?

sell it and get one of the ASUS tri-fan 4870 X2's or get one of the arctic cooling heatsinks for the X2.
