I've had one of my big transmitters shut down due to AC failure in the building and when the temp. hit 95° F., the SS stuff just said "No Mas!" and hit the "idle" mode. Once I got on site, I ended up using a bottle (#200) of compressed Nitrogen to "spray out" the cottonwood that infested the AC Compressor unit outside the building. Once that was done, the AC could then operate properly. When the building FINALLY got down below 94° F., we got back on the air and stayed there.

SS stuff DOES NOT LIKE heat whatsoever...and a laptop just JAMS anything into every nook and cranny. IF your fan is starting to make any noise DIFFERENT from when it was new, you're in for a world of hurt in the operating department.

See if there's an upgrade in the CFM parameters, but be careful there...even TOO much air movement can SOMETIMES still result in "thermal shutdowns" like what you're seeing...the root cause is this; NOW the air is being pulled so fast from the container, that it has changed the flow patterns enough that the critical stuff may not even be in the main air flow path anymore.

An increase of a few CFM are fine, but doubling or just going "hog wild" may make the situation worse instead of fixing the problem altogether.

Another aspect to keep in mind...have you added anything to the original computer from the day you bought it? Then, you're operating over the design parameters already unless you already upgraded the fan too.

And the power supply. There's a whole book on what you may be looking at there too.

Just last week, I had one external PS unit come to me...it turned out the gal ran over the cord (carpeted office) with her wheeled office chair. She pinched the cable bad enough that the "sense line" for the PS was broken and the supply couldn't regulate the power requirements enough to keep her laptop from hanging/crashing.

Remember, those cables are a bit more fragile than anyone will tell you. That's why you should do everything in your power to be sure the cables are properly bundled and UP and OFF the FLOORS.

AND DON'T LET ANYONE WALK/STEP ON YOUR CABLES!!!

Kick 'em in the shins if they think you're joking. Better yet, send them the bill for a new cable or three. They'll watch where they're stepping in the future...gauranteed.
