I decided to biounlock my cpu (Athlon ii x4 640 clocked @ 3.0ghz). Before biounlocking my idle temp (As told by speedfan AND coretemp) was about 20c. After biounlocking and booting my computer up, both softwares read at about 54c at idle and it jumps up to 60c when browsing. The temp is the same, regardless of the core I unlock. Unlocking 3 and 4 give the same readings.
My cooler is the The Hyper 212+ which is an amazing cooler and a step up from AMD's stock cooler. I am also using a cooler master case with two mounted fans. Is the temp reading wrong or is it really that hot? Is this dangerous for my CPU?
EDIT: I would also like to add that the fans are completely cleaned out, dust free and there is plenty of room in the case for airflow.
