no CPU fan(reverse cool) or CPU fan....

[bgd]

I upgraded a dell dimension 2400 recently and was surprised to see the
silent duct work over cpu.A compaq I had was a disaster with it a few years
ago. Despising my own custom pc's buzzing cpu fan, I did the same with duct
work from pc remnants. Any facts I should know, aside that I am quite
impressed with its performance?
The heatsink is a copper core open bottom. Logically, it made sense to do
what i did, so far very good results.I removed fan on cpu and filled space
with what was missing for proper tension.
The bigger system fan at 1980 rpm steady , silent, is doing more than my OEM
heavier duty Intel Cpu fan at 3500 rpm!
Also, my volts went up on everything, including cpu, which could only
indicate system is allowing cpu to do more.... (I have a chip on msi mobo
that does this), and it is still cooler: 12 degrees idle and 2 degrees full
load.
I have a feeling I am missing something and unsure about what I
did.....Anybody tried this? I have a 2100 dollar compaq disaster still
churning through my head.

I answered own question, and would recommend reverse cooling to anybody. Is
it safe to assume the cpu fan is an attempt at a basic universal standard?
Now off to fix a pc with the exact same setup as mine, but with 4 system
fans that suck up the pet hairs while flashing the disco lights on a psu 200
watts bigger than mine.......

the plexiglass is sOooooooo Cooooooooool.
Eat it up kids, Mmmmmmm, just like candy......
