I have read somewhere that Haswell processors heat up too much compared to the Ivy Bridge processor. I have even read that haswell processors run 15 degrees hotter than an Ivy Bridge processor! Reason given is the inbuilt voltage regulator called Fully integrated voltage regulator (FIVR) in the processor itself. So, Is this true that these processors heat up more? Even if it is true, does this affects the normal working on a computer with a haswell processor?
