How hot do your GPU's run? I have a 7950 WF3 it is running at about 67c with 70% fan speed. How hot do you think is too hot?

Have a friend his GPUS run at 90C ..then again one of them blew up too...
anything over 80 is a iffy idea...

Just got back from returning a 6970 that idled at 80 degrees and jumped to 100 less than 2 seconds after cgminer starts up.
My 7850's stay below 70, though.

I have 7950s undervolted/overclocked with fans at 60%, they hover at 59-60c

Overclocked, running at 78-85 degrees depending on ambient. 3+months no problems. Consensus seems to be this is a little too hot.

Mostly 95C but a couple of 7950s run at 100C. Not good I guess and the weather is only getting hotter!

73-74°C at 100% fan speed. Is this risky?

Wow! How long have they been running like that? I wouldn't expect they will last more than a few months at those temps. Maybe try undervolting or reducing clocks to keep them below 90C? |

My 7950's all run 64-68C with the fans at 75%. Running at 1185 core, 200 mem, 1.08V.

The lifespan of your fans drop dramatically running full tilt like that. I keep my cards around 75%, temp is ~78C. During winter months I get sub 70 C... |

I would not be surprised if those burn out before you make ROI. |

2x7970's in an open case 4x120mm fans blowing straight on them and card fans @ 85%. When sandwiched together, whichever card I have in the top slot rockets to 100C easily and would keep on rising if I didn't stop cgminer. The bottom card in this configuration only gets to about 75C. On their own they comfortably sit between 60-65C, so I'm waiting on powered risers to arrive so I can hash with both the cards again instead of just the one. This should hopefully solve my cooling issue or at least stop the insanely high temps.

2x7950 in a computer case tend to run around 70-74C and get 590kH/s on 989 Core Clock and 1479 Mem Clock, but I undervolted to 979mV. Undervolting is magical, without undervolting one of the cards hit 96C, which was way too high for my liking...

Mine are voltage locked so I'm up shit creek in a manner of speaking. In saying that, I CBF reflashing to a different bios and seeing as having one card in at a time doesn't go past 70C, I'm keeping fingers crossed that these risers will help me out somewhat in spacing the cards out more and allowing more air to flow around them. Had a constant temp of 65C last night given it was a rather cold evening and the lowest I got was 59C... These are the Ghz editions non reference I might add. Edit: Argh didn't read you stated 7950, thought it was 7970 - My bad  |

Sapphire HD6970 @ 75C Asus HD7850 @ 74C Gigashyte HD7950 @ 69C All cards in a well ventilated Define XL R2. Just pulled the HD5870 which ran at 92C with fan at 100%. Saved 150W at the wall too. Fan is OK and heat sink is clean. TIM replaced recently. I think it's just f**ked.  |

This. I moved back to BTC for the summer - 21C outside, all windows open in house, computer room was sitting at 34C overnight when mining LTC!  Stays below 28C doing BTC, and saves 200W at the wall. |

For me, a 5mhz increase comes at a sweet spot where it comes with a 5°C increase. Go from 1000 to 1005 on the 7970 and it jumps from 83 to 88. Not good.
However, AMD says these things run stable at 90-92 as maximum temperature target. They are supposed to take peaks of 105. So 85-88 should theoretically not damage them
