Corsair Link 4.9.4.28? (or any in the 4.9.xx series). Yes, Corsair has some issues to fix there. It is not limited to AIDA or other monitoring programs. Their own Link program will lose the fans connected to the Commander Pro even without AIDA, HWINFO, etc. If you can, roll back to 4.8.3.8. This was before the current issues began and is compatible with seemingly everything else. However, if you have brand new RGB stuff from them (LL, ML-RGB fans, etc.), the older version may not work for those.
