It's definitely a problem with HWiNFO, I have the same problem and prior to the 7.42 update this issue didn't occur. iCUE software is not runningThis is most likely due to newly added support of Commander CORE, CORE XT, ST.
Which cooling model are you using?
Did HWiNFO monitor your fans in previous versions?
Do you have the iCUE software running?

The issue persists unfortunately.Please try this build with activated CorsairLink support and monitoring of the Core device and let me know if the issue persists: www.hwinfo.com/beta/hwi64_743_5031.zip
I'd recommend build 5031 as that might fix the problem with Commander CORE support.
