Where is the CPU fan on Corsair One?

[vett93]

I notice on the HWMonitor, it shows a CPU fan. But when I open up the Corsair One, I don't see a CPU fan, as it is water cooled. Anyone know where that CPU fan is?

The pump is connected to the CPU Fan header on the motherboard.

Thanks. The iCUE dashboard shows the CPU pump. The speed is about half of what is reported by HWMonitor. I am wondering if they are the same item.

[DevBiker]

They are based on the same value, specifically the pump speed.

I took a screen of both of them at the same time. iCUE shows the CPU Pump running at 1870rpm. HWMonitor shows 3534. Am I missing something? Please advise.

HWmonitor shows the speed pulse from the pump.

The pump impeller has two little magnets embedded in. For balance purposes, it can't have just one magnet to send one pulse per rotation.

So all water pumps (AOI and custom loop pumps) send two pulses per rotation.

HWinfo shows the raw value, iCUE divides it by two to display the real pump speed.

Got it. Very useful info. Thanks again.
