Two things. first does your MoBo have a temp probe? my MoBo has two but MBM says three and one is always at 69f. It just aint there, and second where/how did you install the fans. It is possibe to creat a "dead" spot in your case by not having your fans blowing/sucking in the correct spots, and NO just because the case has a fan spot it is not alwasy the corect place.
