Broke 2 fan blades.

post #1 of 25
Thread Starter 

hi

i have a XFX hd radeon 6770 1gb GPU.

 

yesterday i was trying to figure out a way to place an fan around the gpu so that i cools the vrms.

but i was doing that while the pc was on doh.gif

 

well,i was careless enough the let the edge of the fan i was about the place touch the gpy heatsink fan blades and 2 blades fell off.

i removed the fan and used those super glue adhesives.i did it very carefully and to the best of my abilities.

 

now the fan doesnt seem unbalanced i.e. i dont see a 'wobble' while the fan is running.

also running the gpu on full load(kombustor and gpu folding) and fan at 70%-80%,i am not feeling any extra vibration form the card,there is little vibration,but it was there even b4 i damaged the fan.

 

so now is it safe to let the card run this way?

XFX wont just give me only the fan.i will have to buy the whole HS+fan and i will have to pay for it.

should i simply disconnect this broken fan and stick a new fan on the HS?

 

after fixing the fan blades,my temperatures ar exactly the same.

61C during the day while folding.48C at idle.

57C at night while folding,43C at idle.

It'll fall apart sooner or later taking other blades with it. Just buy a replacement heatshink now and get it over with.

as long as you're sure it won't come off while it is on, then i don't see anything wrong with it.

Hmm, if you are running the card for very long hours, I wouldnt just glue it tgt. the turbulence of the air though it would not cause any problems now, will eventually cause the glue to weaken and cause the fan to snap and probably send the blades flying into the GPU chipset area, creating an even bigger problem.

I guess you can see how the fan works and probably just attach another fan in, considering the 6770 isnt that hot anyway. If not, just replace the entire thing.

Well,the adhesive is something like super glue.once stuck,its pretty hard to take it apart.even with a solvent.so i am pretty sure it wont come off soon.

i will search for a replacement fan once i get the time.i think i saw an Accelero S1 Rev 2 here on OCN market place.

thanks for the input :)

thats what i think i should do.i believe the glue i used will hold it for atleast a few weeks.

i know this cause i have used is on a 120 mm case fan blade which i broke(yes,i am that careless!!damn me!) and its been running fine since the past few weeks.taking into account the amount of heat and rpm a gpu fan moves,i give it a couple of weeks.by then i will decide on an alternate cooling medium and install it :)

thanks for the input :)

It will come apart sooner than later that been said I don't think it would do much damage when the blades fly off the second time. If I where you I run it with the glue repair while you look for a more permanent fix like a new fan or cooler.

Edit: seems I'm a bit late with my post. Oh well biggrin.gif

a broken blade is not the ultimate damage that can happen and in no way going to result in a dead gpu!replacing a fan will work too.fixing a high cfm fan may even work better than the stock fan!

any 1 of these.

PS-i had done a similar thing for my cpu stock heatsink during the foldathon.dropped my temps by 5C!simply stick a bigger,better fan over the stock fan(unplug the stock fan first tough :P )

and I LOVE MY CARD! wubsmiley.gif

I broke many fan blades and to fix it I used Epoxy instead of Super Glue. Epoxy will give me enough time to adjust by rotating the fan to find its balance. Otherwise, out of balance will vibrate and will not last very long until you need to find a replacement or the whole HSF.

 

Alternately, try to talk to XFX nicely, they might send you one.

difficuilt fix, you must be acurate or your fan will be un-balanced which could lead to more probles... replace what you can now is the best option thumb.gif
