Apparently it showed in HWiNFO with the sensor ID as 0xfc00ae00 (using HWiNFO shared memory viewer) but after updating to this version it not showing anything related to pump fan at all? Seems like the Corsair device somehow disappeared from list of sensors.
Already enabled I think, currently using with Rainmeter right now. Previous version did show the corsair pump in the sensor list.
Its weird that corsair still shows these values, unless they changed the protocol or something else (the missing fan in the screenshot is intentional as I'm waiting to replace that fan right now)
As expected. Unless I could try to disable the option then restart the machine then enable the option then restart the machine again to see if it could fix that. But usually updating HWiNFO did not requires restarting and the corsair pump sensor still shows up.
HWiNFO cannot access the cooler device (Access Denied). Most likely some other tool is blocking access to it.
If you're running such (even the Corsair software), try to start HWiNFO first.
