[SOLVED] CPU fan error problem

[Exminer]

recently got a new pc, but been having a CPU fan error on start up.
the error disappears after a restart.
ive been in contact with the retailer to fix it and tried all their fixes like making sure the cable is seated correctly and making sure its set to PWM in BIOS.
they sent me a replacement fan but still has the same error

this is what ive got
MOTHERBOARD: Asus TUF Z390-PLUS GAMING Motherboard
COOLER: Arctic Freezer 7 Pro V2 CPU Cooler

could this be a problem with the motherboard?

have you plugged it into the correct header

there are 2 headers at the top both are for the cpu fan but the first one at the top is for the actual first fan the second is for another fan so it may be its not detecting the fan even if its powering it on

board picture in the manual shows this

I have the same cooler or atleast the the same series... Its normal because these coolers have a "silent" mode (when just browsing web the fan is not spinning) but has a gaming mode too (when gaming you will see the fan spinning)

yeh its in the CPU FAN header not the CPU OPT

so would taking it out of silent mode "fix" the issue?

There's 2 fixes.
The first is in bios, set the low rpm to 0 or disable cpu alarm. Not recommended as bios uses that alarm if there really is a fan/cooling issue and the fan hits below threshold rpm.
Second is to disable the 'silent mode', which was a bone-headed sales gimmick from the start considering Arctic knows there's a low rpm alarm on the cpu_fan header. Which guaranteed will go off if there's 0 rpm on the cpu fan.

took awhile to reply but wanted to be sure over the weekend

changed the fan from 'silent mode' to 'normal mode' but the problem still happened.
but what i did was change the fan speed to manual so it ran faster on start up and over the weekend and multiple startup's didnt bring up the error. so hopfully 'fixed' the issue

Seems the minimum speed on that fan is lower than the alarm threshold in bios. Manually changing the low-end duty cycle or manually changing the threshold should work like a champ. You'll just have to remember that little detail should you ever reset bios to factory defaults or update, which can reset your settings.
