Has anyone done any research on reversing the airflow? AND even putting the fan on the other end and pulling the air through?

My temps at 750mhz:
Before: 67-71° at 80%
Now: 54-59 at 70%
Is it possible that your fan had been set the wrong way from the factory? Can you confirm which direction the air flows now after you switched? And how about sound, did it change in any way (especially the pitch)?
The fan used to suck air in, now its blowing out. Speed is about 1k rpm less.
To avoid confusion, it pushed air in, now it is pulling air out, correct?
correct
Sorry to burst your bubble, but you are creating false readings and you are putting stress on the unit.
There are 4 chips on each board and 3 x boards, total of 12 chips, the sensor is on the last chip to the rear bottom of each board, the other 3 chips on the board are at the front near the fan, if you reverse the fan the sensored chip is getting cold air first and the other 3 chips on the board are getting hotter air, also the senor pcb is getting fresh air first, not good scenario for the 3 unsensord chips which is now hotter than the sensored chip and the fan is not activating to their real temps.
Normally they are always cooler than the sensored chip and have no need to be monitored.
