Motherboard - Gigabyte Z170XP-SLI
CPU - i7 6700K OC'd to 4.4GHz
Cooler - Noctua NH-D15S w/single 140mm fan
Front Case Fan - Generic 140mm fan
Rear Case Fan - Noctua NF-A12x25 120mm fan
OS - Windows 10
I have an issue where the Noctua fans ramp up to 100% in certain circumstances regardless of the fan profile selected in the BIOS. The cpu fan ramps up when temperatures reach around 66 degrees, while the rear case fan occasionally ramps up for a period of time while playing a game (even if temps are below 60). The CPU fan is plugged into the CPU_FAN header, rear case fan is plugged into SYS_FAN1, and the front case fan is plugged into SYS_FAN3. Sometimes, the rear case fan has reached peaks of 2600rpm, even though the supposed max speed is 2000rpm. Where it gets especially annoying is when the CPU temps spike close to 70 degrees, and the fans ramp up to max speed before subsequently ramping back down. This can happen consecutively with temperature spikes when I'm, for instance, letting a 3D scene render or playing a CPU-heavy game like Red Dead Redemption 2.
Which leads to the question, should I update my BIOS to see if that fixes this issue? I'm currently on f6, the latest version being f22f. It mentions that the BIOS can't be downgraded after the fact back to the current version, and I'm wary of the risks of updating, especially since there's no other noticeable issues apart from this fan curve thing. And if updating the BIOS is the right move, what's the best method? Using Qflash?
The strange thing is that this ramp up problem only started occurring when I switched out the stock fans on my old Corsair h80 for 2 Noctua NF-A12x25s, since they were making grinding noises on startup. This carried over after switching the h80 out for the D15S, though it at least happens less frequently due to the improved cooling performance. Could it be a case of the current BIOS not having proper support for the Noctua fans?
