Hi guys
im running an I7 990x CPU, i notice a 5-6 degree variant between the hottest and coldest core

is this normal ?

Ive noticed it both @ stock and overclocked there seems to be a 5 to 6 degree difference between the highest and lowest core

it peaks at about 50deg @ stock and about 65 deg @4 GHz

anyone else have differences between cores ? and how much

this is 100 % normal. those sensors are not that reliable in precision, some core can work harder too
