Title: 7850 safe temperature levels?
Post by: AlgoSwan on April 14, 2013, 05:10:26 PM
Am I in danger for running my 7850 GPU 78~81 °C six hours without a break?

there is a reason cgminer normal target temp are 75 or below....

So, if it is running 75 °C, no need to worry, right? Manufacturers of these cards claim that high endurance on high temperatures, but I guess they didn't analyse it in BTC mining with loaded all the time. You know some games are running above 80 °C all the time, but this loading may slow time to time. Should we mimic the same procedure to slow-down our mining rigs sometime in mining process or should we stay same loading all the time?

If all your GPU sensors are at 80oC or below, I wouldn't worry about it (or 85oC, for that matter)

the problem is, a lot of the time you'll run into a crap thermal paste job and while it may say 80oC on the main sensor, one of the others is at 95oC, etc..

Most of my cards run at below 70oC, but I do have a couple that I ran at around 80oC last summer, shrug...

I'm running two 7850s at 60C with no overclock and default cgminer settings. I've got a few slots space in between them. I had three cards, but temps wer up to 70, 75, and 102! Removing the middle card drastically helped with airflow. Is your case closed? Maybe try upping the voltage on your fans to get more CFM?

Update: running two at about 73-75C now after 24hr 99% load. I would like to keep under 70C but at full load continually it's just not realistic.
