Could it be that the fans instaled are'nt up to the job
Anything is possible, did you run speedfan...??
It will give you current temps/fanspeeds-- should warn if anything's out of whack--
(
IF you get some
totally crazy result-- that usually means the app does not recognize that particular sensor-chip on your motherboard... so don't panic)
On a PC that new-- it is unlikely that the cooler is inadequate... that would cost a lot for the maker.
It would be helpful to know the maker/model so I could check specs,etc.
