If you use MB onboard fan controller every time it hit set point it will cause CPU polling and result mouse feel off. I went in set DC static speed per fan and no more weird mouse when poling fan speed change due to temp changes. Also if you have 3 points like this move them all way back.

This subforum is for advanced users only. This separate area is for niche or unexpected lag issues such as electromagnetic interference (EMI, EMF, electrical, radiofrequency, etc). Interference of all kinds (wired, wireless, external, internal, environment, bad component) can cause error-correction (ECC) latencies like a bad modem connection, except internally in a circuit. ECC = retransmits = lag. Troubleshooting may require university degree. Your lag issue is likely not EMI.

Re: MB fan controller polling causing mouse lag
Did you mean CPU fan speed settings?
Re: MB fan controller polling causing mouse lag
Any fans you connect and control in BIOS.

Re: MB fan controller polling causing mouse lag
It's nice that you are sharing your every theory with us, but please go back to your last one and either close it or put a disclaimer saying that the lag came back.
Today you're doing Bios tweaks, tomorrow you might start advising people on buying extra/other hardware. I know I'd fall for those threads 3 years ago when this lag all started, and I did, and I ended up burning a lot of cash for absolutely 0 benefit.

Re: MB fan controller polling causing mouse lag
this happens, because we don't have a place where we keep summarising what we are trying before.
when you create that place, do you know what happens next? you will see as you try the same things, again and again, running in a circle.
I didn't see anything new solution since 2010. Everything was written in this forum people tried between 2002-2010 years .

You need start belive that the issue is outside the PC and software (internet included too) thats important…
Absolutely no one bothers with such nonsense, no one changes the fan settings, and for sure, in the normal place, these settings do not affect the mouse

If we can say that electric is like fuel and this fuel make the PC run…. If is bad fuel then PC/ car will not go smooth right?
EMI - Electro magnetic interference - i do not belive that this is the issue for us one bit….
Electric is the issue because thats the only input energy to my PC…
There is no issue with PC at all (tested)
Sad thing is that in 2022 ppl have hard time solve input/output and start twisting things like EMI RFI and so on
Re: MB fan controller polling causing mouse lag
I also believe that my "Smart Fan Tuning", or whatever it's called, creates more mouse lag than without the tuning. Maybe this is something similar.
This is also at least the second time someone claiming that tuning the fans or plugging the fans off helps with input lag. I've tried plugging my Case fans off but it didn't seem to make a difference at first sight - so I didn't look into it more.

Re: MB fan controller polling causing mouse lag
Just make it clear basic case fan DC 12V - the power is coming out of the PSU DC 12V to ATX connector
if fan needs spins faster just draw more amps at 12V
Mouse is powered DC 5V - the 5V DC is coming from PSU to ATX connector
How the hell 5V and 12V can even be afected by each other?
Did your mouse work smooth when you has the fan on high spin or low spin?

1. DC means direct current which means it doesn't change voltage meaning there's less electrical disturbance than PWM (pulse width mode)
2. When you aren't using a fan curve the bios doesn't use SMI's. Smi's cause latency spikes.
