I'm a little concerned about leaving my pc on hashing away 24/7 ! has anyone run into any problems ?!

cheers onis

Turn your PC off, remove your CPU cooler, and turn your PC back on. Watch what happens.

Fail safe in action.

Don't worry about fires, it won't happen. Your PC will shut down WAY before that happens, whether you are CPU or GPU mining.

I've fried CPUs, and GPUs by having a poorly secured cooler or a broken fan on the cooler. I've heard there is a failsafe on ATI cards, but I wouldn't personally try it. But you'd definitely get a fried card before you got a fire, unless your power supply was faulty, which can happen but it's rare.

I had a fan on one of my 5830's that was clogged up with a cable, without me realizing it. It stayed under 95c by clocking down to 300/150 until it cooled a bit, then clocking back up to 600/300, then back down, all automatically. I was wondering why my hash rate was so low with that particular card. Tongue

But basically, the card will still survive just fine even with a non-functioning fan. I'd say the only risk is if the heatsink itself becomes detached from the card, but if that happens without you realizing it, there's probably other issues with your computer that you need to work on anyway. Tongue
