Odd behavior Fan control Arctic Freezer 3

Hi,

Twice now i have started my PC from a cold boot and the fans on the AF3 have been going full speed. i look in the Fan control software and rather than having the temps it has a ? symbol with the fans at 1700 RPM.
to solve the issue each time turn the Auto CPU toggle off and on again and the fans go back to the norm speed or 850 rpm with fan speed of 35% displaying . Should i be worried or is this a Fan control gitch. installed a brand new AF3 only 2 months ago. been flawless till now.

Thanks

Paul

What’s the AF3’s fan cable connected to and what are you using to control the speeds?

connceted to the CPU fan header using the combined cable. Using Fan control software to control the speeds.

At what point are the fans ramping up, as you turn the PC on or after Windows starts to load and what temps are showing in the BIOS? I’m not sure what Auto COU is, some sort of auto-overclocking feature? Have you tried with BIOS defaults?

get rid of the controller soft wear and lot the motherboard do it thing, or get a proper fan controller.

From your description of problem it sounds like controller isn't receiving / registering CPU temp signal.
Like already stated, try using motherboard fan control software. There's a good chance it will do the job just fine.
If it doesn't, as stated get a proper fan control.
