Hello all!
I recently installed a corsair h75 AIO water cooler and the two fans it came with. Only one issue, my Asus motherboard BIOS wants to protect me from myself (a bit late for that) and limits the duty cycle to 40% minimum for all the chassis fan headers. I think my CPU fan header might have a lower manual duty cycle of around 20% but I'd rather not screw with that because i'd prefer to keep my CPU fan to auto adjusts speed based on core temps.
Anyway, preface out of the way, the thing I wanted to ask you lovely ladies and gentlemen of the LTT forum is: What can I do to limit the rpm of my fans...
Silly question I know, but besides forking out ~$50 for a PWM fan controller, maybe there are some other things that could be done? I'm not adverse to installing some ghetto resistor in line to the fans considering I have already voided the warranty on just about everything in my case (the aforementioned h75 was for my GPU after all...). But I'm pretty sure the old "voltage divider" resistor trick doesn't work with PWM fans anyways...
So, got any ideas? I'd rather not spend money tbh as it's a bit hard to come by right now.
And yes, before anyone comments that this thread has already been made a million times, I'm doing it because I know how much you all LOVE answering questions that have already been asked before
