5850 - now sounds like a jet after a power outage...

[hotwired007]

my mining rig - 1x 5870, 1x 5850 and 2 USB Block exploders got hard powered off this morning when the toaster tripped the house power :S

after bring it back online the fan on teh 5850 now sounds like a leaf blower - its an ASUS HD 5850 - its it worth replacing the fan?

I would fix it, even if it's just to resell it.  I've bought several of these (if your 5850 uses reference-style cooling):

yeah its reference

the card still runs fine so is it it worth replacing then?

if the card is fine a fan is cheap, i'd be suspect of the card without a through test though I know I lost one during a power outage the entire board was discolored slightly, it would still boot but got hot and loud quick.

its mining happily atm

the whole rig has surge protectors and i'm considering adding a UPS into the mix too

If it's mining fine, did it just get kicked into a higher fan speed % than what it was running at previously?  I have a couple reference cards that are LOUD at 100%.  maybe try restarting your miner manually setting the gpu-fan to something manually, if you haven't tried that already?

example:  --gpu-fan 75

From my experience, once they start making a lot of noise, it's only a matter of time before the fan seizes.

Any chance you're running the fan at 100% now and you weren't previously?

Yeah, I have blown two 5830's and a 5870 because of running fans to high.  Currently I have one 5830 being cooled with a zip tied on 92mm delta (nice noise from that) and my other cards are watercooled.

fan runs at 80% i believe - Afterburner has a custon fan control on it to keep all the cards below 70 although i am switchign to an open air rig in the next week or so, so hopefully i wont need the custom control and i'll revert to 'automatic'

i have a couple of 120mm deltas that i plan on using in the 'summer' (in the UK - so summer is a loose description for a couple of warmer than normal weeks )

Hmm, 80% isn't too bad, it can be loud, but not leaf blower loud.  I'd look into obtaining a replacement fan, or an aftermarket cooler (locally I've seen seen Arctic coolers for 5850's going for about $20).  I'm not sure how well a 120mm delta will cool an reference-style card unless you take off the shroud and strap a couple onto the heatsink, that actually may work pretty well

i was going to use it to pump air into the case but as i'm adding an additional card on risers and having two 220mm fans to blow onto/into the system they may well end up being redundant - my office is 10x6 and i have a small airconditioning unit that i may use but obvously running that 24/7 will increase my operating expenses

i ahve just checked and in the middle of the day the GPUs are at 83 and fans are at 100%

open case will have to be finished this week or i'll have to dial down my GPUs
