Title: Mining at 30% fan speed Post by: janpec1000 on January 19, 2014, 08:59:44 PM Hey guys,
I am having problem at momment. Mining rig is very loud and i would need it to operate at 30% fan speed of GPU at maximum. Problem now is that at even at 100% fan speed temperature on GPU r9 290x gets to 95 degrees and becomes unstable. Cards are inside box which is large and has very good airflow few vents (case is closed). Should it be better to leave case open, or should i just buy big went to blow directly into cards? Any suggestion is good. Also is it possible to use water cooling system for cooling only and have fan runing at 30% would that work on keeping temperatures bellow 90?

Preferably on open air, PCI-e risers and an household fan blowing at the cards. You can skip one the 3 before IF you seriously undervolt cards and monitor temps, and even then it's not recommended. The way you're doing it, cards don't last long. Title: Re: Mining at 30% fan speed Post by: kalnas on January 19, 2014, 09:53:44 PM There is no way u can run this with 30% fan in a room temperature. And with water cooling there would be no gpu fan at all.

Slightly off-topic here, but what are the estimates on how much mining shortens the lifespan of a card?Preferably on open air, PCI-e risers and an household fan blowing at the cards. You can skip one the 3 before IF you seriously undervolt cards and monitor temps, and even then it's not recommended. The way you're doing it, cards don't last long. I have an nvidia gtx 680, if I leave the fan speeds at auto it'll go to 83-84C. If I set the fans at full, it'll drop to 68-70C. I guess I should be running the fan at full speed when mining? I'm investigating on leading cold air to the computer. Since it's currently -15 to -20C here for many weeks to come, and many months of below 0, it would be beneficial. I have to study and experiment a bit on moisture to make sure it doesn't start stacking up inside the computer. Title: Re: Mining at 30% fan speed Post by: cdog on January 20, 2014, 06:02:00 AM The lifespan for a mining card is probably 2 years MAX. For gaming, maybe 3-4 years. Its obsolete at that point anyway.
Temps wont damage your card, voltage does. 95c+ temps just cause HW errors, stales and dropouts/thermal throttling 90c mining 24/7 is fine for any modern AMD card Title: Re: Mining at 30% fan speed Post by: janpec1000 on January 20, 2014, 10:52:31 AM As for liquid cooling i heard that it has vent on its "fridge" too and its also quite noisy. Can anyone confirm?
I am just looking at any possible solution that i can do becouse noise is too strong and i am runing out of ideas what to do. I will underclock card but i am sure that wont be enough, i need some solution where i can run fan speed max at 30-40% on GPU.

You can mount some big and slow fans on radiator, like 14cm and it will be pretty quiet. Also for maximum silence you need maximum size of radiator.
