Hi everyone,
I've been lately building a full DIY water cooling, a small radiator and a personal made water block for full gpu coverage. After hours of usage (gaming tests without VSync and 99% gpu usage) max temp is around 62 celsius which I think is pretty decent.
Now I'm stuck with fan speed adjustment:
The stock fans were 2x PWM 12v 0.31amp and adjusting them with MSI was easy. So I replaced them with 2x PWM 12v 0.30amp. I made a bridge and connected them to the vga fan header.
The new fan speeds were about 600rpm at 30% and 1200rpm at 100% when connected to a PWM header on the motherboard.
When connected to the vga header, speeds are 900rpm at 30% and 1200 at 40% (MSI Afterburner). Mid ranges are somewhat linear % to speed.
Since the "silent" mode of the fans are below 800rpm and the GPU is cool I'd like to lower fan speeds but I'm unable to.
I've checked wiring for anything wrong and it all seems ok, and more or less there is a pwm regulation. Also the new fans should be compatible, and when connected to the motherboard they rotate correctly.
There is also a loooooong time, about 5 to 8 secs, since adjusting a manual speed and when the fans reach it. It's more like a wait time, not that the fans start to adjust to the new speed and 8 secs after it reaches it.
Any ideas?
