How to repair MSi Twin Frozr heatsink Fans, or How to Fix Fans where there is no hole behind the sticker - Page 3

.. smile.gif .. looks like u didn´t read my text carefully; i´m not drilling "off center" and the very small hole is no obstacle - no oil leaking (in towers, fans are running upside down - hole up btw.). further more i linked the source for completely new fan assy. for ~ $ 15,-, which fits perfectly to the msi hawk twin frozr. in fact risk of damage by scratching or breaking fan pcb during disassembly (i tried that too) is far more in place than with the drilling - if one´s careful enough.thumb.gif

My GTX460 Hawk had a fan that was very stiff and would spin very slowly.
It actually came that way. I RMA'd a card that had a noisy fan, and got this one back. Anyway, the fan got really noisy and is still stiff, it only twitches at low RPM and won't even spin slowly until high RPM. So I thought I would take it apart. Unfortunately, I didn't have the luck of the OP. Even using a plastic knife, the plastic base shattered and I managed to knock a resistor and capacitor off the board. I have no idea where they went, most likely swallowed by the carpet, so they are long gone.

I'll have to guess on the capacitor (C4) since they are unmarked, but does anyone have a fan board and a magnifying glass and can tell me what resistor R8 says on it? It's covered by the base plastic and I'm not going to attempt to pull it off the good fan seeing as how well this went the first time.

.. knowing, that this is no correct answer to your question: you might not be able to repair that, even if you take the efforts to find and replace components. why not using the replacement i mentioned earlier? this is perfectly working - for ~ 15 bucks. ;-)
(btw: i also demolished one board by trying to disassemble; after that, i drilled and lubricated the fan-set on the second msi card - perfect, and ordered replacement for the first) smile.gif

Yeah, you're right, buying a new fan assembly is probably the best way to go. I'm just being cheap, because I just saw the price you bought it for in your link is no longer current, they have since raised the price to $19.49. I guess that's not much difference, but I was hoping not to have to put much money into an old card (the fan assembly cost is probably half the card's value).

I do wish I'd just drilled a hole for lubrication instead. I admit I was initially reading this thread on my phone and only saw OP's post, I didn't read further because my phone screen is small, so I didn't see the idea about drilling holes for lubrication until I pulled up the thread later on my PC. I think drilling holes is definitely the safer way to go. Those small components aren't soldered to the board very well and didn't take much force to knock off.

EDIT: Just found this for $12.39, think it will work?
Main difference I see is it has an extra inline connector, but that might even be a good thing.

.. no idea, but it LOOKS like it could do the job. wink.gif

Nope. frown.gif The one I bought does not work, at least not for the MSI GTX460 Hawk version. The cable is too short and won't reach the connector. I was a little concerned about that when I ordered, but it's really hard to judge cable length from a pic. Unfortunately, I was right to worry. Anyway, I made it work by cutting, splicing, and soldering the fans into the original wiring, but definitely not an ideal solution and a bit less aesthetically pleasing since there is electrical tape on the splices rather than a nice continuous heatshrink like before, but does work fine.

So for anyone who has the GTX460 Hawk, don't buy the fans I linked to!

Thank you for the instructions and the video link. I have noticed my fans have become louder in my case. At first I thought it was the cpu heatsink fans but discovered it is my MSI GTX560-Ti. I started looking at aftermarket heatsinks but the cost is not worth it now that the GPU is a couple years old. Going to give your steps for lubing the fan a shot.

So I tried to fix the fan before reading this guide and now that transistor has come off. My question is that will the fan still work ? As its only function is to control fan speed I guess.
If not then is there any way that I can put it back in its place ?

Also the fan's movement is quite stiff due to which it is not spinning and temps going 90+. Any way I can fix that ?
Fixed that by making a hole just beside the center with a VERY hot needle and then putting in a drop or two of oil

.. it MIGHT, but it doesn´t HAVE to; as soon as the pcb is broken, fans might produce errors not running or spinning full speed. the lubrication (as described before) DOES work (if u get the oil into the bearing in the center); the pcb - however - has to be undamaged.
.. btw. i don´t think that 15 or 20 $ for a spare (IF u have already damaged pcb) is not worth the thing; my gtx 460 hawks still do a good job each (single card) - even with games like crysis, gta iv, tomb raider 3, asassins´s creed 4 or dayz (arma) in almost high resolution with 1920x1200; but - just MY opinion! smile.gif
