Hey guys, I got a used MSI Gaming X GTX 1080 from a friend of mine on an insane deal. It had 2 broken fan blades on one of the fans which made it completely unstable and would tremble the whole building. (It isn't related but it had an unstable voltage and after much troubleshooting I downclocked it 200MHz down to reference and now it's mint).
Facing that my case airflow is great and it's winter in Vancouver (the GPU wouldn't go beyond 68C on 40% fan speed), I decided to cut out the broken fan (with the promise of buying a new on AliExpress), temperatures are great, it doesn't go beyond 70C no matter what.
The problem is that now the remaining fan ramps up fine but then doesn't ramp down, and it never respects any kind of fan curve (tried MSI Afterburner which worked fine before removing the broken fan). If I restart the PC it goes to a stop, mildly ramps up, but when I launch something graphics intensive it ramps up and gets stuck, never ramping down, obnoxiously loud.
It's one of those set of fans that they merge together into a single fan header in the GPU, no connectors to be removed, so I had to cut it.
My question is, does anyone here with enough electrical savviness could propose a solution to get this fan quiet? Like an adapter, for the severed part or for the header itself, maybe cutting the wires deeper? (My cut was near the fan, not near the header).
Disclaimer: I tried searching physical stores for replacement parts, tried North America wide and only found a $150 listing on Amazon. AlliExpress has good enough replacements for $14+$2 shipping. So I needed a temporary solution.
And honestly, if I can make this fan behave as intended, I may keep it the way it is.
By the way, the fan curve reports properly on GPU-Z (sensors) but the tachometer doesn't, it's always 0 (kindof as expected).
Thanks very much for the effort guys! Sorry about the long post, I tried being as thorough and clear as possible.
