i7 3770k core 3 way colder than the others?

[fishfishyfish]

I know my overall temps are fairly low, but I'd like to know if I should be worried that core 3 is so much colder than the others? Or that core 1 is so much hotter rather?

I've put on my cooler many times to not much of a difference.

It would be awesome If I could get the rest of the cores the same temp as core 3

It might just be a faulty sensor, having that sort of drop is not usual. Don't worry doh, it dosn't mean your cooler is bad.
