Constant High GPU Temps Bad?

[unlock.mk]

Hello,

If I am mining with my GPU 24/7 (R9 280x), at a pretty much constant temp of 65C, and have my fans running around 2000-2500 RPM will it decrease the lifespan of my GPU? How long till it might stop working?

Would water cooling it help my GPU "live longer" by keeping it at low temperatures?

How long has your GPU been running 24/7?

Thank you.

i have old HD5800 and HD5970 cards at constatnt temperature of 85C for a year! and still running at full speed. i think that will never end, so, at 65C it will running forever. Also you got to know, that gpu's needs that temp to run smootly, it is working temperature.
 i have tested mine to run at very low weather temperature outside = -15, and i was strugling to start mining, but after sometime, when they reached 50C gpu start mining normally.
So cold is not always better for gpu's.

I have 4x 7970 that have been running for 2 years, first fan broke yesterday.

When they where mining LTC the temp was about 75c, now with XMR they stay around 55c.

I would stay below 80c and keep fans running on as low a RPM as possible at that temp.

Undervolting can do wonders for fan speed and GPU lifespan.
