Running dual display on GTX580 makes everything runs really hot

I have been using GTX580 to run dual display. The core temperature is increased by 15-20C after the 2nd displayed is fired up.
The case temperature is increased by 5 degree.
The case is blowing out hot air as opposed to room temperature air.

I am considering to just buy a cheap pci-e card just for the 2nd display so that everything can run cooler.
However, I realize that the 2nd card can potentially generate even more heat.

Can someone recommend me a card that runs really cool?
I don't need to run 3d on the 2nd card.

thanks.

When running two very high-end cards like that, your temps will raise. Do you not need SLi to run three monitors with Nvidia cards?

He was talking about buying a really cheap, like $30 card to run the 2nd monitor.

As far as that goes, it will lower the temps at idle. At load, it won't make much of a difference, other than it already has a head start on getting to it's load temps. The reason it's hot when running 2 monitors, is not because it's doing a lot more work, but because the clocks don't power down as low as when you only have 1 monitor. Once you are in 3d mode, it will be the same.

http://www.newegg.com/Product/Product.aspx?Item=N82E168... $33.00 and free shipping boom done, supported on windows 7 i have the exact same card running in a server here works perfectly and honestly shouldn't bring your temps up at all especially since you don't plan on running 3d applications on it.

If tomshardware messes up the link just search newegg for N82E16814125289

Thanks everyone.
I think my goal is find a card that is as cool as possible and as quiet as possible.
Since I will not be running 3d on the 2nd card, the performance is not important.
My resolution will only be 1080p.
Would a passive heatsink be a better option? I think 8400 and GT210 both come in passive (without fan).

Thanks.

That may be a good option, another possible option is to get a 220 or 240 for a dedicated PhysX card.

Dedicated PhysX is a great idea.
Thanks for bringing that up.

Would I still benefit from a GT 240 based on my configuration.
I5 760 clocked at 4ghz, 8gb ram and GTX580?

Does it make a difference if I go with something slower like GT 220 or something better like GT 450?

My goal still is to minimize heat and noise.
PhysX would just be a nice addition.
I am happy with a single card 580's performance.

For PhysX, the best performance you can gain seems to be the GTX260. Beyond a gtx260, the benchmarks I've seen do not give any noticeable gain.

Most people would consider a 240 to be the sweet spot.
