Large power supply does not increase computer performance.
That is classic urban myth. Either computer gets sufficient
power to execute the instruction at same speed - or computer
crashes. The PSU is not a motor. A bigger PSU does not make
the computer work faster. Either the computer executes at the
speed of that master crystal oscillator - or it crashes -
stops working.

Same applies to CPU heat. Again, either CPU runs as crystal
oscillator speed or it crashes. Cooling does not make a CPU
run faster.

Freeze up = crash...I think you're arguing semantics here. If the old p.s.
was undersized for the computer--or if the output had deteriorated for some
reason--the new, more powerful supply could well be the source of improved
performance.

As far as air flow: IIRC, AT supply fans *exhausted* air from the supply;
while ATX fans 'suck.' I don't know if that's a hard & fast rule, but I
seem to recall the above as one of the changes when the ATX standard took
effect.

If you have the technical chops, you can easily reverse the airflow by
opening the p.s. and turning the fan around. If your CPU has no fan, by all
means get one. If you are 'really' concerned about airflow within the
enclosure, buy an auxiliary case fan--orienting it so that the airflow
supports that of the p.s. fan. Every case with which I'm familiar already
has a cutout with screw holes for one. Any computer store, electronics
supply store or even Radio Shack carries these.

Well, that "Could" increase performance. I would say that
putting a power supply two times the amount then you had was
the true increase of performance. However, the freezing up
problem can be caused by MANY things.

Yup.

Furthermore, the cooler you can get that Processor, the better
it will run.

To use basic language: I assure you a definite upper limit to the
CPU's speed exists, and once this limit is reached, cooling
further will have no effect.
