Hi,
As long as you keep your chip below 80°c, it should be fine.
IMHO, the major risk is to reduce its lifetime.
Check the fan speed, if the driver does not indicate 100%, then it should be able to deal fine with 74°c.
Cheers !
Ah, I tried it out for an hour or two and it seems the max temp is 76°c-77°c. This specific model has three fans built in, but I'm almost 100% sure they were running at max speed.
And by reducing it's lifetime, say I mined for 6 hours every day; how bad would that be? Thanks for the help!
