MCE Thermal Event

Hi,
recently I started to notice these messages in the journal and I'm not quite sure how to interpret them

I have a MacBook Air with the Haswell i7 CPU.
These messages only appear while compiling or doing other CPU heavy stuff.
Are these messages anything to worry about, or do they just tell me that the CPU reached it's thermal limit and throttles down and everything is ok and running as intended?

Thanks for your help.
