[SOLVED] CPU temperature varies between cores under heavy load (prime 95)

[GGOD]

so i decided to change the thermal paste of my cpu since it has been a while since i installed it (around 4.5 years) ,after i did so i decided to run a stress test and see which temps im getting ,i used prime95 for that ,and the temps i got were as follows (core 0 and 1 were around 69-73 ,while core 2 and 3 were around 63-66) for all the period of the test ,noting that when idle they are around (32-35) pretty close temps overall ,i got a bit confused so i tried applying the thermal paste a second time ,but i got the same results ,btw my cpu is the i5-6400 with the stock intel cooler ,can anyone tell me if this is normal please ?

it's perfectly normal for all cores to be at slightly different temperatures.
as i'm writing this mine are currently ranging from 30-33°C.
during stress testing it is still normal for them to have an even higher variation of temps.
