Question is my computer messed up or are the fans on an aio not temp controlled?

Just got a new pre-built pc and it came with an aio. Never had anything besides air cooling before.

However, I'm very confused about the fans on the aio. Instead of the motherboard controlling the fans, the fan speeds seem to only be controllable via a remote control. Shouldn't they show up on the bios and adjust with the CPU temp?


My fan rpm read outs seem a bit weird too and makes me wonder if my pump is even working right.

On HWMonitor there are only two fans "CPU" and "Chassis #1".
  • The "CPU" fan rpm readout doesn't change when I use the remote control to slow or speed up the fan, however I can clearly hear the fan getting faster or slower.
  • When I use a program to slow or speed up "CPU" I hear "something" change in the PC tower, but it doesn't sound like a fan so I think it might be the pump.
  • The "Chassis #1" rpm readout, which seems to be my 4 case fans, random jumps between 0 to in the 1000s. Setting them to 0 RPM via a program does stop all the case fans, the aio fan doesn't stop.

I believe the aio in my PC is a CHIONE M2-240R .

Thanks for any help.
 
Most likely your fans are connected to a fan hub which then connects to your PC. This would make controlling your fan speeds a little difficult if your hub doesn't work well with your onboard fan control software. First identify what software, if any, is controlling the fan speeds. Some motherboards have dedicated software for fan controls that you can download on your motherboard's official manufacturer website or you could try to control it in your BIOS.

Yes the aio fans are connected to the CHIONE M2-240R's fan hub.

I think the case fans are all connected together and put on a single chassis header on the mobo, there are still two chassis fan headers free.

I think the only way the fan hub is connect to the mobo is through a sata connection and an rgb header, which I'm assuming means the fan hub's fan speeds aren't controllable via the motherboard?

Does it make more sense for me to connect the two aio fans to the two free chassis headers?

Yeah SATA connection doesn't let you control fan speed. You'll need to take the fan cables out of the hub and see if you can plug them into your motherboard.

it seems the fans only have 8 pin connectors and I can't find a way to connect them to my motherboard (PRIME Z690-P WIFI D4).

Ah then you have a cheap brand that comes with proprietary connectors. Unfortunately those require the hub they came with, sucks I know... Makes it completely useless outside its own ecosystem, ya know, unless you mod the cable yourself - which I don't' advise. Unfortunately you're stuck with whatever the speed those fans ramp up to. Maybe there's a port on the hub itself that can connect to a motherboard fan header?

The company's site says the remote control to the proprietary hub has fan speed controls. But they're not going to be tied to the motherboard's temperature. They're almost certainly expected to run at static speeds.

nope, doesn't look like it can connect to the motherboard fan header.

yea I think you're right, just a super cheap aio.




The aio pump, which I believe is connected to the "CPU_FAN" header, also sounds like a vacuum cleaner anywhere above 70% max rpm.

Guess I'll probably have to buy a new one eventually

ty for the help
