Windows 7 64 & Ubuntu 64
2nd graphics card is running hot while the other is fairly cool?

Ok this has been going on for some time.

I've got two dual video cards on my computer. I have two 19" dell monitors & one 22" monitor & my 46" samsung lcd that becomes the 4th when its hooked up (which right now it isnt)

I built this computer 2 years ago, ran a Nvidia 9600GT for a few months & added a 9800GT With the 3 monitors and ran it great for almost a year. Then I started running into problems.

I had the 9600GT burn out, sent it to Asus, they replaced it. It burnt out again.

They sent be a 9800GT replacement.

I took the original 9800GT and put it in PCIx2 to do an experiment and put the new one in PCIx1

Now for some reason the old card which has been working fine seems to be running on the hotter side, while the new card seems fairly cool.

The one on the right has been the slot giving me problems & is currently the one running hot.

They are both hooked up with power. I'm running

8g ram
Intel Quad core Q6600
Asus P5k LGA 775
500G HDD
Sony DVD player that sucks & doesnt seem to work half the time (I'm upgrading to bluray soon anyways)
Rosewill RX630-S-B 630W ATX12V v2.2 & EPS12V v2.91 SLI Ready CrossFire

Any idea whats going on? Is a hot graphics card something to worry about? I'm going to monitor it with the top open to catch it in case something starts to happen.

It just sucks I have to baby my machine like this when it was working fine for so long.


Could it be the PCI slot? I dont think its the power supply because everything is working fine & I've never had any problems with it.

On top of that I've got two of the three monitors plugged into the cool card while the 22" is running on it's own on the hot card?

Nothing makes any sense.

Some people say it's impossible for it to be the PCI slot.

I'm going to swap power cables tomorrow just forge hell of it to see if the other one gets hot tomorrow.

I'm sure it could be spread further apart of things were ideal. But it's already a pretty big case to begin with (Origen 10 or 11 maybe, I forget the exact model #)
