GPU Fan Replacement

Fri Jan 19, 2018 1:27 pm

I have an XFX 7850, which still works fine, but I believe the fan bearings are shot. I believe it's this model:
https://www.newegg.com/Product/Product. ... 6814150642

The fan starts and stops constantly, and makes a zzzt zzzt zzzt noise, which vibrates the whole PC. When I blow on the fan blades with a can of air it stops immediately after I stop the air.

I think I can replace the fan if I can get a replacement that will fit. I have written to XFX but they have not replied (the card is long past warranty.)

Is there a way I could find a generic replacement fan that will fit my card?

Also, might WD-40 help? Would that be dangerous to the card if it dripped out of the fan?

XFX sent me a replacement fan for a 5830 a year ago. Not sure what their holdup is for your case, but don't lose hope.

Have you looked on ebay for the model # of the fan you're needing to replace? (you'll have to take the existing fan off the heatsink to find that info)

You could also try disassembling it, and cleaning/oiling the bearings. Not a permanent fix, but might get you another 6-12 months out of the existing fan.

I bought an entire city's lifetime supply of sewing machine oil for $6 (the only size bottle Walmart had). Worked like a charm.

As an alternative, most non-blower type heats inks will work very well with a garden variety 120mm fan attached - I do it mainly for quiet / my sanity. Cables ties give a lovely ghetto - chic look, but experiment with other attachment schemes if your like; you're only limited by your imagination, resources, and physics.

Yeah, that stuff is something special. I fixed some laptop fans with sewing machine oil, and they not only lasted longer than they did originally but they kept working until the laptop was too old to use anymore. As long as whatever was in the fan wasn't too gunked up or dried out before ya added the sewing machine oil it it should keep working great.

Sleeve bearings (sintered bushings) and mineral oil are best of buddies, provided you catch the problem before they get so dry that they sieze up and seal the pores of the bushing.

Sounds like you got to yours just in time! :)

LOL!

I have also removed the current fan and replaced with various over sized fans when the original stops working.
Drywall screws work really well! :D

Way back in the day, I replaced a dead GPU fan with a passive chipset fan. Blocked 2 adjacent PCI slots, but I wasn't using those slots anyway so I didn't care.

I hacked up a Pentium 66 heatsink (the pin-type) and put it on my core lapped ti4200 back in the day. Even passively cooled (well, case fans alone) it ran a hundred+ MHz faster while never really even getting warm.

I miss the good old days of "hmm, that looks like it should fit". :P


Re-oiling sleeve bearings can bring them back to life for quite a while, so it's worth a shot even though disassembly usually is the bulk of the work on GPUs.
