Long time lurker here, and I owe most of my tech knowledge to the Tek Syndicate Community.
As stated in the title, one of the fins on my gpu fan broke off during a gaming session, and the rattling and noise is getting unbearable. I also am concerned about damaging the pci slot on my motherboard due to the vibration. I really like this card because I only game at 1080p and really am not looking to upgrade (YET).
I want to have a lot cooler gpu temps, along with a quieter overall gaming experience, and I have found the NZXT Kraken g10 and the Arctic Accelero Extreme 4 to be two options, but I am torn. I am kind of leaning towards the g10 just because I like the radiator aspect, but would appreciate any input before I impulse buy one of these two.
i've litterally had more broken gpu fans than i've had gpus so i'm pretty experienced fixing them at this point... just use some gorilla glue it works great. If you want a more serious bond you could get some plastic epoxy. Just don't apply it too excessively or you'll throw the fan out of whack. If you could take some pictures I could give more specific suggestions on how to go about the repair.
You could just spend a little more and get new fans, personally i'm a cheap ass though and prefer just to fix them.
for an exact match on fans there should be an ID on the back of the fan you can reference and search,
I had to add to the fans on my old GTX 465. The blower cooler did not work well and the GPU would constantly over heat and crash at 80C. I screwed a 90mm fan over the squirrel cage fan and it worked to keep the temps under control.
Alternatively I broke a case fan blade so I broke off 2 more blades to keep it balanced. I don't think I lost much cooling.
