I would have to concur with, defective temp. sensor, as 15C is only 59F!!! Unless the computer's in an extremely frigid datacenter, I would imagine the ambient air temperature would be higher than 59F! You try to assign the VM's to the low temperature core and see if there is any change; if not, I would highly suspect the sensor as being faulty. You may ...

The problem ended up being a poorly fit heatsink. Maybe poorly fit isn't the right description. Turns out, you have to put thermal paste on the heatsink, not the plastic cover that goes over the heatsink. After removing the plastic cover, the CPU is nice and cool, thanks everyone!

In my experience, it is normal for paired components in a case to run at different temperatures, because airflow is not the same everywhere. Here's a graph of HDD temperature from my colo box. The drives are mirrored, so the workloads on them are near to identical. As you can see, they track each other, but they're not the same; they're also, on ...

This could be either cooling or uneven loading (given the temp difference your situation is probably uneven loading). You should use something like prime95 to load all the cores evenly and see if the temps still vary. If they don't then you need to balance the VMs, check that your apps are multithreaded and busy. How to do that depends on your software and ...

It is not. Unless you have some serious issues with the airflow. Or one of the coolers is bad. Temperature WILL vary - but not that much (70 vs. 15 degree celsius). Given how low 15 degree is I would assume (a) your sensor is off (you really store the server in a that cool room?). I would also assume one of the CPU does simply no work at all, for whatever ...
