I've got an Asus Radeon HD 4850 that the fan has recently started to make an annoying noise on and I'm debating what's best to do about it.

Sending it back for an RMA doesn't sound that appealing when it could be weeks before it's returned, so I'm thinking of just replacing the cooler with another one until such a time that the 5850's come down in price.

My dilemna is that the board is a non reference one, so I'm unsure which of the OCUK range of coolers will fit properly, and whether extra heatsinks are needed.

Any advice welcomed.
 
I have a Palit HD4850, the fan was noisy from day 1 (spun faster than a fast spinning thing - like a Formula 1 car engine). It was a small fan, sat in the moddle of the circular heatsink.

I employed the use of 2 cable ties, and a larger fan (about 90mm, I think). The card now runs just as cool as it used to, without the whine.

A word of warning. Make sure you connect the new fan securely to a 12v supply. I was happily playing Crysis, when suddenly there was a smell of burning and a slight puff of smoke, followed by a sudden shutdown of my PC. I thought the graphics card had popped it`s clogs. The heatsink was way too hot to touch. One of the power leads to the fan had fallen out of the connector. 10 minutes later, everything worked fine, and has done since !
 
Ive also got the Vortex on mine, connected to a fan controller sat at 5v, keeps it 34c idle, 54 load :) mine was a Saphire one so close to the reference card.
 
Accelero s1 + 800 rpm 120mm fan cable tied to it = almost silent = 40c-45c gaming load.

Shame you have no mm access as I have my old one which sat on my old 4850 gathering dust.
 
Cheers for the help guys, I've ordered the Neo and some decent TIM. Confirmed this with Akasa direct by exchanging pictures of the 4850 I've got that the cooler should fit just fine.

Don't forget the VRM's as they can get very toasty on 4800 series cards.

I'm going to assume that the card has heatsinks on already, and if so I'll recycle. The Vortexx's contact plate is much larger than the Asus cooler, so I think it'll be alright (if not, I guess I'll be getting the 5850 a bit quicker than I wanted :P )

I have an Accelero S1 on each of my 8800GTs awesome coolers, I cant fit fans on them in SLI though but the temps are still 20-30 degrees cooler than the standard heatsink and fan.
