temp issues (sorry if this is in the wrong forum)

[humanevil]

i just rebuilt my pc as i got a water cooler and a new case soi done a cpu burn test and while my cpu was at 37 degrees the auxtin0 hit 128 degrees and auxtin1 hit 50 and my pc shut down so what is this auxtin1 and how can i sort it as ive never had this issue before.

EDIT
just ran the test with prime 95 and within 7 mins my temps hit 92 degrees im running a stock i7 6700k with a coolermaster 280 aio the air venting from the rad seems really cool considering the temps so would this be a thermal paste issue ?

auxtin0 and auxtin1 are auxiliary sensors not all motherboards have them, so can give a false reading, that is what I have read, have you checked that the water block is seated properly? maybe take it off and reseat/paste.
