Topic: Sapphire 5850 Fan Dead - page 5. (Read 24941 times)
This is most likely easily fixed by adding some lubricant. I've 'fixed' quite a lot of fans with the same symptoms this way. There are tons of guides for this also. Some random one I googled - http://www.techrepublic.com/article/quiet-noisy-computer-fans-with-a-drop-of-oil/5034842
And my Sapphire 5850 fan just died.... 500rpm at 100% speed.
I'm not sure if this would work for you as I don't (yet) have a Sapphire card, but I was able to get my fanspeed pretty low (~30%) by affixing a case fan near the ports pulling air out.
A twist-tie works fine, though if you have DVI ports sticking out you will want to space it with a small shim. Its similar to placing a fan on the other exhaust, except I found it much easier to attach it to the metal there. It seems to me the metal conducts quite a bit of heat so it effectively acts as a passive cooler, with the added fan it works even better. I think a single fan could assist with the cooling of two cards in this way.
Edit: The fan I have is low CFM, and nearly silent. A high CFM fan would certainly do an even better job lowering temp and fan speed.

You guys ran these 5850s fans at 100% speed?
I'm currently running at 72% (24/7 ofc), how much time till it breaks? :]

wow, all we miners just found another defective product made by sapphire.
no wonder their 5850/5830 are so much cheaper than other brands.
lesson learned: you get what you paid for.
From now on, I will only buy cards with LIFETIME warranty.

get an accelero twin turbo already!!!!! 
do that fit on sapphire PCB ? This question, but for the centrally-mounted XFX 5850...mine is almost dead as well (1200 rpm all the time, with no control).

phelix: Great information, thank you!
I'm wondering if I can take the plastic casing off, and set some regular ole computer cases fans on it. Not sure if that will pump enough air to keep it cool.
my second best solution would have been to buy a 80x80x15 fan (e.g. Titan) cut off the cladding so that it will fit in and somehow try to fix it with the original mounting holes.

I was away for the weekend and was monitoring my mhash/s on BTCGuild.com, and I noticed one card (normally my hottest card) running unusually slow... 75 mhash/s down from close to 300 mhash/s. When I got home, the fan was making this grumbling noise intermittently, then would stop. There was also vibration going on. Turns out Ive got the same problem, my fan has crapped out. Ive got a spare 5850 Xtreme cooler that Im not using, but I might be better off RMAing the card and just getting a new one. The card was still running, but at 95C, and Ive lost the ability to control the fan... CCC will try to make it run, but it just makes a low vibrating noise when it does.
I did take the cooler off and replace the TIM when I first got it, would Sapphire have a problem with that? I know some manufacturers let you do things like that, and some void the warranty when you take the cooler off. I can always give it a shot anyways.

The fans just aren't very durable. I've had 2 fans out of 8 have the same problem now, one 5850 and one 5970. The 5850 never ran higher than in the low 30% and the 5970 was usually well below 50%, so although it will probably make it last longer it's no guarantee against failure. Both cards have stock ATI coolers.
Aftermarket cooling is too expensive.
Officially you will loose your warranty if you unscrew the fan.
I had exactly the same problem: http://forum.bitcoin.org/index.php?topic=10341
The engine oil I tried to get in did not really help.
With a really really thin mirror
I managed to take this picture:
So this Sapphire HD 5850 has a FD8015H12S fan from FirstD
I could only find it on this polish website http://www.bujnowicz.com/product_info.php?products_id=5063 but they did not respond to my english eMail. It's less than $7 so I would like to buy two just in case another one dies.
Anyway, my solution was to cut a hole into the case and put an additional fan right below the card. Mostly this is my coolest card now.
Another option might be to get a fan that fits in there (80x80x15) though it might be a hassle to fixate it.

Thanks for the advice guys.
I think I'll try to disassemble it and unstick the fan. RMA would take too bloody long. Worst case I can use it as-is but won't be able to overclock it anymore, which is fine.

You could always buy a aftermarket heatsink.

its just luck
Guess it's luck as well.
I've run a 5850 for over a year now at 90% fan speed 24/7 and nothing has happened (famous last words)..

One of my 5830 fans just crapped out today. I ran it at 100% 24/7 though due to retarded PCI-e slot placement on my motherboard. I'm thinking about just RMAing it though, mining is getting difficult to the point where it's worth $5 a day not to have that damn noise. That or I could get it repaired and sell it.
The bearings are gone. That card is useless unless you get another heatsink/fan. Chalk it up as a loss and learn a lesson. NEVER run a fan over 50% 24/7
Fuck, i run it at 60%, i'll need another fan soon. * kr105 is changing his fan speed to 49%
