gpu temps

[green-eyed-bandit]

my gtx 275 can get pretty hot , if i run 2 in sli will the individual temps be just as hot or will they lower a bit sine they will be sharing the load

They will run just as hot 90c is normal for high performance cards.

[tinymouse2]

They'll probably be slightly hotter due to the lack of air supply. Also the ambient temperature in the case will rise.

Also they don't share the load as such but stack ontop of each other. The only SLI rig I setup was 1 degree cooler with dual 9800GTs. So you might shave 1 or 2 degrees off but as far as I know it won't decrease the temp.

90C is NOT normal for video cards. you can handle those temps for a while but keeping at that temp will damage your video cards and the rest of your system. get a better cooling solution

They'll run hotter. Especially if pressed up against each other.

Try increasing the fan speed manually to get lower temps.

What is the rez of your monitor? If it's not 1920x180 or higher you won't benefit at all from another card, and if your CPU isn't clocked high you'll see minimal gains as well.

Why does my graphics card run hot

That's a pretty wide monitor :D

90 degrees is fine for quite a few cards. I thought my max on my 260 was 85 degrees but after contacting peoples I've found out that the maximum safe running temp is 105 degrees.
The maximum of the 275 is also 105 degrees so your still quite a bit off your limit.

Also if this is for gaming why not go for DX11? Just a suggestion and it's kinda off topic but I would say it's worth it, it looks fantastic.

all I was saying is that having a video card at very high heats will decrease the longevity of your computer parts. chronic high heat can reduce their life by 2-3 years

It's true that the GPU won't live as long but it'll live a lot longer than it would do than if it was up at 105 degrees :D

Incorrect. 90C is happy and healthy for a modern GPU.

I prefer to keep temps down as do a lot of people. It gives you much more OC potential which a lot of folks on here (go figure; it's overcolckers.com) seem to want.

The nVidia engineers have designed these cards for worst-case scenarios. I prefer to work toward a best-case. I add or reduce voltage, adjust the BIOS settings, and modify the cooling of the card and my case for optimal performance. I take pride in tweaking out almost anything I own and enjoy. Remember Tim "The Toolman" Taylor? "More power!"

[jarlmaster47]

no bull****. my 4890 never exceeds 55C. got to keep it cool and safe!

That's a very cold 4890... What are your specs? Your GPU might be bottlenecked by your CPU causing a lower load.

[green-eyed-bandit]

no way tinymouse. no bottlenecking for me. I have an i7 920 at 3.6 ghz, 6 gigs of kingston hyperx ddr3 ram at 1200mhz with 7-8-7-20 timing and some other stuff that is inconsequential. my psu is 900w in case that has anything to do with it.

There's definitely no bottleneck :P Unless your PSU is seriously muffed up.
What case do you have? Also aftermarket cooler?

[jarlmaster47]

aftermarket cooler is the monsoon IIIlt and a vigor cyclone case

[tinymouse2]

well that explains it XD

Remember Tim "The Toolman" Taylor? "More power!"I agree with your point this is the overcloking forms and cool temps means better overclocking. However the OP is worried about GPU temps and first he needs to learn what the stock temp range of a IC is before showing him how to get a chip on it's ragged edge by cooling then overcloking moving more curent though the chip then raising the voltage in the chip.

nvidia never made any change Electromigration on a IC has always been around the same temp. I remember from the beginning when it was just passive cooling and no temp gage to wory about. 40-90c is a safe zone always has been
If you don't believe me google Electromigration.


This is a vary simple analgy, think of it like this metal takes a certain temp to melt before melting there is migration at certain temp. even low temp reading on the temp gage with high voltage and curent still heats the metal in the IC to migrate.

Aculy it's striping atoms.
