I just added two msi duke cards and with 100% tdp 80% fan they run about 63-64c. This is in a 6gpu frame with fans blowing on them ambient 20-22c.
Kinda disappointed they run so warm with huge coolers on them.
What do you guys like to see for temps? Is mid 60s OK for 24/7 use?
According to the subreddit for gpumining, anything under 70C is fine for mining. Above that and you want to reduce temps unless you really want them hashes now at the expense of your hardware. Don't even know how you would keep it under 60C in certain parts of the world... at least in a regular home setting.
Keep in mind that gamers tax gpus more than mining since varying temperature stresses electronics more than stable temps, and how often do they replace gpus because they died? Statistically you're more likely to replace gpus for upgrades, it's outliers that actually have them die.
Fans though, apparently those need replacement sometimes.
