GPU cooling question

Hello all. I have a PC with a Radeon 6770 HD that has been overheating lately. My technician came and replaced fans and the card itself and it still seems to be overheating. Dell went through driver installation and all that. This problem is still an issue. It stays in the 60-70 celcius range and after a game it is aroun 80 and can sometimes even CLIMB to 95 an hour after I've played a game. What could be causing this issue?

It is very clean and the vents are all clear. This is also happening with the replacement card as well as the original (both 6770 hd). The case is the standard case that the dell xps 8300 uses. mrguy123

No, it's been a long time since I've messed with the inside of a PC. I don't have any aftermarket products in there. I was told I didn't have a space for an extra fan. Could I replace one of the existing ones with a more powerful one?mrguy123

Dell's XPS 8300 desktop PC is available with a Second Generation Intel Core i7 CPU and it can be used for practically any task, except hardcore gaming.PCWorld

This thing is still under warranty as it's only 7 months old. The next step they are taking is replacing the motherboard! I guess I have to jump through the hoops until they replace the case. I'm amazed thy they even offer this configuration if it is an issue like this.mrguy123

I suppose if the case can't be replaced, I'll just have to deal with it. I don't know the first thing about moving things to a new case. At least I have an extended warranty so when it burns up, they'll fix it. Thanks sllmrguy123

As I've mentioned in other threads, you can provide improved cooling directly to the video card (if that's an option for you). Take a look at these:

how do you find out if your cards are over heating?

I guess my question is this: why after seven months is this now a problem? Up until a few weeks ago, the idle temp of the card was 30-40 Celsius and after a game, 75 max. Now, when I turn the PC on and launch speedfan, I can watch the temp of the GPU rise to 60-80 in just a few minutes. After the technician installed a new GPU, the fan seemed louder and more efficient, but after restarting, it seems to run only about 1500 rpms. Last night, an hour after I played a game, it he temp was a record high of 96 cel is and would not drop. After watching it stay there for 10 mi utes, I shut the computer down. Can there be other hardware issues? Like instructions not being relayed by the motherboard. I wouldn't call myself a hardcore gamer but it seems like I should at least be able to play my MMO more thn an hour without my PC overheating.mrguy123
