Ok, yes it does! 



You would probably want to check any documentation that came with the

big fan to see where to plug it, because it's obviously running at too

low speeds! In case the fan has a built in thermometer (which it

obviously does, in case it's running at diffirent speeds on a PS power

plug), you might check if it's attached to the CPU the right way (a

special CPU glue should be between the CPU and the cooling ribs, while

the fan should be screwed to the ribs).



It would be somewhat a good idea to unplug that old CPU fan in the

aspect of electricity consumption (inside the box I mean, belive me it's

rather important to keep it low). Considering it's pluged to the board

(usualy just pins in slots system), a simple pull should do, but if it

dosen't seem so, you might try and aditional squeeze. If it's not a pins

in slots system at all, you might want to describe it to us. In case the

wires go directly into the board, which I doubt, the idea would be to

cut them more to the fan end, so you can fuse them back togather in case

the missing fan prooves to be a problem for the hardware. In either

case, tell us how many wires does it have.



Simply ignoring the 450MHz CPU won't exactly help, you might want to try

it again once you get the fan problem fixed. If you get any other

solution for the supposably dead CPU, please pass the news too me too,

because I think I might have gotten my old 486's killed in sub-zero

temperatures.



Anyway, read the CPU fan names (and names of all related hardware) and

consult the Internet; it holds various articles from the hardware

factories and other sources, that could help you solve your problem and

it's knowledge that you can't expect from any of us, because we aren't

walking libraries, just people.



C'ya!
