Windows/Bios affect PSU output?

[dahyippur]

I'm going mad trying to troubleshoot something. I have a rgb fan that will flicker or change color intermittently only after the computer has booted into windows. The fan runs off a sata power cable and does not connect to the motherboard. I've replaced the fan and the PSU but the problem persists. Can anyone tell me, will software like bios or windows affect the output of my PSU on this lone sata power cable?

 

The fan works properly in other machines

What happens when the PC starts with the fan unplugged, and you plug it in while it's running?

I've never heard of an RGB Fan that doesn't have any communication with the Motherboard and Windows cannot affect what the PSU outputs, I suspect it's a program that has control over the BIOS or the RGB that's causing this.

Maybe it's those ones with a remote controller? in that case they might be affected by the PWM signal? I'm not sure

It does include its own remote and fan hub thats powered by sata (fan is not powered by direct sata connection). Strange that it doesn't happen with any of my other desktops, and only after windows launches.

 

I replaced the PSU, fan, fan hub & remote, but any combination of these things connected to my microATX board has issues.

A ha!

 

What is the model of the fan/fan controller?

Its UpHere RGB123-3 from amazon. The fan/hub was my first suspicion, and they sent me a second set for the sake of troubleshooting. Only later I realized the original and replacement pack work flawlessly outside of this one trouble system. Leaves me wondering if its possible for my mobo/front panel/gpu/anything to alter the output from my PSU

LOL!  That garbage is made for people that don't care.  Return the whole kit.

This board doesn't have any kind of RGBsync, and I thought they looked good for $20! I don't know enough about power supplies to say if its possible for a component to cause some kind of irregularity in power output. I'm curious about the mobo/bios and its asus EPU power saving mode, Intel's EIST and similar features too
