Rainydays - are you running iStat menus? I'm doing an informal survey on this. I am, for the record.
Are you utilizing a lot of mics in your setup? I'm only a little concerned because the vocal booth we built to the back of our studio space is about 7 feet from my mac.
But I've got curtains over entrance to the booth and the voiceovers my wife does are typically recorded to her own 2009 i7 mac. In those cases I'll have mine idling but my own projects tend to be very layered soundtrack type productions.
Linus is annoying at times but he's not completely incorrect. But he's not spot on either.
Still: I wrote this last night on 4790x temperatures, how that data is acquired in the chip and how some of
the data is approximated (so not completely accurate) and some are from sensors and some processes that hit the FPU harder cause the chio to heat up hot by design so using other processes keep the chip cool.

In brief: there are sensors for some of the temperatures but not all of them.
Some types of mathematical processes in the chip make it raise in temperature more than others specifically AVX code that used to be running on the main CPU is now being run on the math coprocessor which produces what one individual said were
unrealistically high temperatures.
I'd be curious if Logic is running its code on the math coprocessor or the main cpu.
I'm running logic over here and have a rather large session. I'm going to see (once it copies from a backup drive) what it does to the fan SPLs using a decibel meter I have.
Stay tuned...
