hello everyone, this is my first post here, I really need some help with this issue and I hope someone with similar issue could provide some insight about this.
so after I took my pc apart for cleaning and re-applying the thermal paste on the processor, when I put everything back I noticed that the motherboard chipset fan (pch fan) was spinning at full speed, so I figured that because I disconnected the motherboard from the psu the bios resetted, so I went into the bios and made sure that the q-fan is enabled and the pch fan control is set to profile and to the lowest setting ( silent), after restarting the pch fan didn`t respond to the to the bios command and still spinning at full speed, which is very laud, i have tried all sort of solutions such as trying different version of bios, other fan profiles, disconnecting the pch fan header and connected it back, but nothing helped, whats really bothering me is the noise, this thing is really Lauder than all my fans in the case and is distracting, what I have also notice is the chassis fan-1 doesn`t report its connected into the bios or fanxpert, it just spins with no fan speed or anything, but apparently when I connect another fan it reports the speed which is weird.
p.s posted this issue in rampage iv extreme owners club but unfortunately got no responds.
I would appreciate if anyone facing similar issue even with different motherboard from different venders as this will help me determine what is causing the problem.
thank you all in advanced waiting for your replies.
