Pfff, I only mine LTC and Im happy if my cards are under 100c. But they are kind of cramped up and OC'd to bejeezus.

My understanding of GPU tech is that the chips can run MUCH hotter than a CPU for long periods.

For a CPU, 90c would be too hot but for a GPU 90c is totally fine, but I have to set fans to 85%+ to get this, so fan life is reduced.

Running gpus at and over 90C will kill them quickly, at least in my experience.  I was running them at ~85C and they were ok until I pushed them over 90C.

Now, I'd recommend staying under the low 80s.

7 5830's in my basement all run between 55c-65c, 1 5830 and 1 5750 upstairs run 62c-70c respectively. Auto fan for the 5830's and the 5750 is set to 85%.

In one location I run them at ~82C because I don't like all the fan noise. In the basement, they run at 75C or less.

BTC mining with (5) 7970's and they range from 65C - 70C all day/night.

No special cooling equip.. Just the stock fans on the cards?

LTC mining at now.
3x7970 ref. 915/1600 49C, 53C, 52C. Hard watercooled  Smiley

How much time and money is spent doing that?
Isn't it hard to justify the exra cost when the margins are so low?

I wonder if I can do something like this:

Good to know.  I have just started and my temp runs about 91c.  I saw in another thread that it's still ok even to run at 110c.
I don't see how someone can run at 70c and get any kind of hashrate.

I'm running 2 7970 at 1200kh for scriptmining.  I haven't tweeked any settings yet.
Just set it at max 20 in Guiminer-script.

I think a lot of people shoot for temps ~70C.
