Title: Replacement fan for MSI R6790?
Post by: dani147624 on May 29, 2012, 07:38:21 PM
I have broken off a blade from the fan on an MSI R6790. I tried contacting the seller and other distributors in the country (Hungary), but they couldn't help. I have received no help from the MSI customer support.
I found a fan for sale at http://www.aliexpress.com/fm-store/508904/211401938-526862961/Power-Logic-is-PLA09215B12H-Diameter8-5-Holes4-3CMGraphics-ball-fan.html (http://www.aliexpress.com/fm-store/508904/211401938-526862961/Power-Logic-is-PLA09215B12H-Diameter8-5-Holes4-3CMGraphics-ball-fan.html), but I find $60 (including shipping) way too much for a fan.

Does someone have any idea, where could I buy a replacement fan?

I thought of somehow fixing a 6cm or 7cm rectangular fan there, but I don't think it would be very efficient.

This one is for the stock AMD Design Cards. The MSI cards from dani is a MSI Design Cooler, wont fit with that fan.

Two options, replace the whole cooler with a aftermarket one, ArticCooling, Akasa, Thermalright etc, or cut one more blade of the fan, so the balance is even on the even. I will try the second option first, because it is already broken and you loose nothing for a try.

can you take a picture of the video card? whats the model of the fan thats in there right now? whats the length between the mounting holes? this is all important information. I bought a 6770 with an obliterated fan and bought a replacement for $4, it screwed in perfect and plugs in perfect and runs perfect now.

http://www.ebay.com/itm/251056663293 is the card I bought that was broken.
http://www.ebay.com/itm/120873623826 is the fan I bought to replace is.

On the page I linked in the OP, there are measurements of the (ridiculously expensive) replacement fan. That is identical to the one on the card.
The one you linked, while a bit smaller (75mm instead of 85mm), would probably fit on the card. If I don't find anything better, I'll probably buy it. For $4 including shipping there is not much risk.

Unfortunately, since I broke off the first blade, I broke off many others. I didn't even think I could "fix" it by breaking off another blade.

Thanks for the quick responses.

If you do choose to go the "chinese fan" route, be wary that shipping could take as long as a month, or more. Also quality -can- be sketchy. I lied when I said it "plugs in perfect". Whoever assembled the fan attached the 2 pin plug on it BACKWARDS (ground would get fed 12v and 12v would get fed ground). I eventually figured this out before burning out the fan and re-attached it the correct way.

Also make sure the power plug you need is correct. The fan I got was only a 2 pin. It didnt provide sensor or have a wire for PWM, but neither did the card.
