Is it normal for one CPU core to always run hotter than the others?
Last response: in CPUs
I've been monitoring Coretemp and noticed my core 0 is always about 5-8 degrees hotter than the other three cores. Specs are Q9450@3.2Ghz w/ Zalman Falal1ty cooler and Antec 900 case. Core 0 is 35-38 at idle with all the others at 30. Under load it always stays about 5-8 degrees hotter, like 45 for core 0 and 38 for the rest. I know it's not close to overheating or anything, I just find it strange. I guess it would make sense for one core to do the majority of the work, but every screenshot I've seen shows all cores at basically the same temp.

It is normal, it is also normal for temp monitoring software to be inaccurate.+1
There are many number of things that can make readings off. So it's very normal to have 1 core higher than another.
Now, If the temp program saying something like 85c on 1 core and the other core 50c, then there an issue.
