Hi Prescient
according to the screenshot you provided, our SW shows the same cpu temp as Realtemp,
so it probably is the pump or fan sensor ic issue, your water 3.0 extreme is still under warranty,
our customer service center will contact you soon, either customer service or our local reseller will send you a new one.
please provide your contact info, like your email, where you live...etc
Before you receive a new one, you may directly connect the fans to mb.
