Core Temperature Difference

I'm running a 3570k at stock speeds and am seeing some odd temperature differences. During gaming, core 0 reaches about 43 C core 1 and 2 are about 4 degrees higher and core 3 reaches 51 C. Is increasing temperatures like this common on ivy bridge or any intel multi core cpu for that matter? Is this of enough concern to warrant a reapplication of the thermal paste? Thanks for any help you can provide in advance.

    Every multicore processor has different temperatures between each core. It is nothing to worry about, because there will ALWAYS be temperature fluctuation between each core.

    The work load threads are never spread across all cores evenly.
  3. Exactly what these guys said, and to add, no 2 cores are created equal so some cores will just run hotter than others while under identical loads. But in your case the program you are using has a core designation it is using which leads to certain cores working harder than others. It's no issue.
