Suppressor-grid modulation by Antonio Vernucci

Heatsinks and Fans - Which Way Should The Air Move by Irv Finkleman VE6BP
I have been wondering which way the fans on my TS-930 should be blowing. Should they take the ambient air from outside and blow it on the heatsink, or should they be evacuating the inside air in the vicinity of the heatsink and blowing it out?
