I'd probably get Moto 360 for my mom, since she's already used to android and actually seems to be getting into this kind of stuff http://www.amazon.com/Motorola-Moto-360-Black-Leather/dp/B00NC8PMUK/ref=sr_1_1?ie=UTF8&qid=1449150088&sr=8-1&keywords=moto+360
they add these splitters with H100i for rad fans, use them to connect fans directly into pump and not MB (that way you can always change fan speeds) and there is one wire as FoxHound said; connect it to MB CPU_FAN slot and if you'll still get this message just ignore it. To make sure your pump is running you can install corsair link (you need to connect your pump to USB with the cable included). Hope this helped
I've had a similar problem, updating BIOS solved it for me
EDIT: sorry, didn't see that you've already tried that , have you installed original copy of windows (DVD, official ISO file)?
