I just sent a ticket from within the software about this issue. It also wiped all my user defined settings like lighting and pump/fan custom curve.
HWiNFO was reporting these 3 values in RTSS (MSI afterburner OSD) so I could monitor while in games. My G15 was reporting pump speed from the Kraken x72, now its back to reporting the speed at the motherboard header. The H20 temp can only be found from USB connection.
IIRC you don't even need cam running to get these readings.
