Question What means squeak sound under load?

[AV10518]

Squeak sound became very loud under load, and even in idle, I can hear like 10% of it (haven't had this previously).

probably the bearings in the radiator fans, some will make noise when not mounted vertically or over time. might've been the video card fan but those don't usually spin @Idle

Nope, just tested all of them by switching off one by one.
I'm pretty sure the sound comes from CPU/VRM area..

Is it normal that clocks and voltages are jumping that much in idle?

By the way, no OC apart from standard XMP.

Sounds like the AIO cooler pump might be going...do you have another cooler you can swap in for testing ? If not you can try unplugging the pump power lead for a couple of seconds to see if the sound disappears.

If it's still there with the pump unplugged you might have something in boards VRM that's going bad...you're sure it's not the gpu or psu making that noise ?

yeah the CPU will boost to complete single tasks quickly (logs or restore points) and return to idle.

is your pump plugged into the CPU header? I see it's a CM - so it would probably be fine in a SYS/CHA header - the radiator fans will react better to temp changes in the CPU or CPU/AUX

Sorry guys for my late reply, I've just returned back to my workplace.

Well, I've tried to unplug AIO cooler pump, but during that short period of time the sound did not dissappear.
I also think that it's VRM making the noise.. Somebody wrote that it's a sign of motherboard's near death.

I'm sure it's not GPU/PSU making the noise. Is it technically possible that defective PSU causing the VRM to make that sound? I don't have another PSU to test unfortunately.

Yes, it's plugged to CPU_OPT header, but the fans to CPU_FAN. I assume that's the correct way to do it.
