After successfully repairing several fans in these, I got to thinking:
Why is the cooling fan sucking in air and dust and blowing that air/dust onto the transformers and then pushing hot air from those transformers right up and onto the processor/control boards before it escapes??
There’s dust and grime and dirt EVERYWHERE after several years in a normal environment.
Would anyone with experience in cooling systems care elaborate on why this makes more sense than having the fan go in the opposite direction - pulling cool air in first through the top as it moves onto and over the control/processor board first then pulls hot air off the transformer cores (out and away from the processors) before finally escaping through the fan and out the bottom vent.
I’m thinking of flipping the fan around in mine and don’t some tests, but not before I’ve heard some expert opinions.
OK. Thanks!
Very cool inside these things 😎 (pun intended).
*oh in case you were wondering-
this one went sorta dead months ago:
~no red light at all
~4000; 0124 readout on panel
so far found that the throttles needed adjustments, red light plug was flopping around inside; filth everywhere - doing a deep cleaning; and suspicious about the control board so I’m going to test that hard before I put it back together completely; have a spare new one on hand just in case
