GPU fan blades

How detrimental is the loss of 1 GPU fan blade on a 6950?

bizzel has yet to learn the way of the Dremel
How many blades are on the fan in total? I assume this a circular, 'blower' type fan like on the stock 6950s?

Short term no issue. Long term because it is not balanced it will wear out the bearings faster and it will eventually fail.
I would suggest that you replace the heat sink with an after market one as opposed to trying to replace just a fan.

Is this a stock cooler that AMD put out or one from the company that shipped it? If it is stock from AMD then buy a different heatsink and fan. If from a different company like Asus for example, contact them to see if you can replace the fan. Should be cheaper and less of a hassle that way.

Depending on what happened warranty might also be an idea?

How did it break?

wont go under warranty as was my own fault, was trying to prop the card up as i removed the wind tunnel (which was holding it up) to get to do some life saving maintainance to the rig and forgot to unplug the gpu so when i was propping it up I caught the fan.

not sure if its a stock cooler, i presume it is, i bought the gpu from ccl last september and thats how it came sealed in the box

It's not the reference cooler, it's VTX3D's own design. You could call it their stockcooler but it's not the stock cooler if you see what I mean?

Anyway, I'd do one of two things. Either rip the shroud and fans off, leaving the heatsink in place, and strap two new fans to it. Or rip the entire lot off and by a different cooler. I'm planning on doing the former to my 470

To retain balance in the fan, break off the opposite fan blade! No more long term problems, and very little short term problems!

does that even work?? cuz I'm just concerned that his fan won't be able to cool it very efficiently since there will be 2 missing blades..

At most, you would be loosing 1/5 of the airflow. In reality, air vortexes and less resistance means you will see a few degrees increase, if anything.

I had considered this, but I made a miss count as i wasn't looking at the GPU but rather trying to count off the best pic I could find on google search so there are 9

It should do in theory as like lp rob1 said it would just reduce the air flow by 20% and also a short term use only.



As it stands now the GPU is out of the rig and in pieces waiting to recieve it's new partner the arctic cooling accelero twin turbo ii





just need that blooming job to start now
