the h100i v2 has a fan reading though it does work but i set it to come on under heavy loads as its pretty loud to have 24/7 - but idle temps without it are fine, gpu is at 28degrees and cpu cores are all 28-30 degreesI'm guessing MB Fan #1 is the H100i v2's fans. They may be connected with a splitter so you just see one fan reading.
GPU and Pump RPM speak for themselves.
Not sure what's going on with MB Fan #4 and #5 lol. Could be a false reading, or could be those 2 case fans you say don't change speed.
