Vote to show what the most common GPU temperature is while mining. Feel free to post info on your rig as well.

I'm sitting at 75 C with 2-6870s and 5 case fans operating at 67%.

I'm water cooled! So my cards rarely see 40°C! Grin
But,if I was air cooled, I'd keep them below 70° as much as possible. and definitely below 80°!

I think I've had my vid card up to 68 once or twice, but that's on a warm day. 
Yes, yes I do go a little nuts with airflow.

So it looks like 68 C - 73 C is the range that I should be shooting for.  I think I'll probably install another fan to get myself in that range (without increasing fan speed so it sounds like an airplane taking off).   Wink

I keep them just below 75C. I try to have the gpu fan RPM as low as possible. Because at 75C, the GPU will last at least 5 years if not more, but GPU fans are likely to fail very fast if you keep it on 100%, the bearings will wear out in at most 2 years.

Is this true?  Anyone else have an opinion on this?

1 x 6950 @ 64c with 10% overclock

I have 7 case fans.

Going to add another 6950 today so temps may rise a little.

If you like my post please feel free to give me some positive rep https://bitcointalk.org/index.php?action=trust;u=18639

I've noticed that after a long period of time, my miners (running Xfire) are sitting at 71 & 78 degrees C.  I think adding another fan might help so I'll probably do that today.  I've underclocked them reducing my Mhash by about 10% in order to keep temps below 80 at all times (I live in the desert and the room with my rig is upstairs in probably the hottest spot in the house). With any luck an additional fan and some better cable management will allow me to return the GPUs to their full clock speed. I'll post the results once I've had a chance to work on my rig.

Generally trying to keep every card under 70c.

However the 6990's I have just wont stay under 75c. Mostly running at 82-91 and prob. wont go any lower without watercooling.

One of my 5830's was running at 90-95c.  The only reason I cared was that it would clock down after it went to 91c, thus losing hashes.  So I reorganized the case cooling a bit (if you want to call what I have "cooling"), and now I see a steady 89c on that card.

The rest of the cards I am running, I can't seem to get that hot.  They all have too good of airflow and not enough overclockability I guess. Even with extra voltage, they're staying below 80c.  Lame - it means I can't run them as hard as they'd like.

Yea as I said, with my original card (Powercolor) I was sitting on 64C @ load with a 10% o/c. Then I added a 2nd card (ASUS) which by default clocks @ 10Mhz higher at the core but even backed off to 800Mhz it sits at 75c @ load as does now the Powercolor (both at default clocks with memory clocks lowered).

I noticed by putting the ASUS into the PCI-E 2.0 x 4 secondary slot it runs @ 75c but in the PCI-E 2.0 x 16 slot it runs at 85c! I can drop the temps to low 70's on both cards but setting manual fan control but then (the ASUS particularly) the fans get a bit noisy. Im also running 7 case fans. 4 are located on the door (2 sucking air out of the case, 2 blowing air in over the cards), 1 fan in the rear, 1 in the front, and 1 in the top.

Im still a bit unsure about my PSU though. Could this have an effect on temps if say it was borderline meeting the power requirements? Its a 700W Coolermaster unit. Im thinking of going for a 750W Corsair or maybe even higher depending on price. I'm running a new ASUS P8P67 board btw.

I try to keep my 5770 <70c.

My 4850 runs around 95 and idles at around 65 but from what I've seen thats normal for these cards. And if it's too hot, oh well, if I burn it up I only traded a spare used hard drive for it so I'm not out much. Undecided

Actually, other than the downtime it would cause I don't care much about the 5770, it has a double lifetime warrenty, as long as XFX doesn't try to screw me out of it or take forever getting me a new one. Cool

My 5850 runs around 80-82. The two 5830s I have going are around 75 if I remember correctly (I don't want to walk across the room).

They're only OC'ed to the CCC limits because a few days ago the power went out, and all of my "stable" OC's in afterburner because very unstable, and I had to go into safe mode to uninstall afterburner. Lesson learned: Don't enable overclocking on start-up with afterburner.

6970 runs around 90 C, fan speed auto

5830 79 C, fan speed 70

I'm a bit concerned about the 6970 temp but well it's on auto and not OC'ed or anything. If it breaks I have a lifetime warranty with XFX.

I bought an ASUS board with 5 Fan connectors and plugged 120mm into it. I have set them to 80% and put them on top of my 58xx cards. The cards themselves are spinning at 100% - in case the crap stock fans break, I have Acceleros waiting to be mounted. My cards, even the middle ones run at below 55°C. The side cards run below 50°C. Stay frosty!

my issue is the case I am using does not seem the best for mining. I have a thermaltake Amour JR. and it does not seem the best for cooling. I got 2 bigger cards coming and well I dont think they will fit in the case. and if they did  I would go caseless but its not the best option atm.

so only 1 5770 is at 80s. Once I add the other 2 cards I can see that going way up. I think i may need to change the case to something with better cooling

I have three case-less motherboards with two overclocked 5770 cards apiece.  The shared UPS draws 860 watts.  The cards are from two different vendors - the Sapphire cards run 10 C cooler, i.e. 60 C and the others 70 C.  I situated them in the crawl space under my Austin Texas house where the ambient temperature is a steady 30 C, despite outdoor temperatures climbing to 38 C (100 F).

They run great with the exception of one Sapphire card which I cannot overclock.

With a single 5870 OC'd 1000/350, I was chillin at around 68C at 50% fan speed IIRC.  However, after I added in a 5830 right beside it, I had to crank the fan speed up to 60% just to get it around 78C. 

The 5830 (990/350) is sitting around 71C at 90% fan speed.
