OT: Refrigeration Compressor fix

Not really the right newsgroup but since your family!

I was cooling my computer using oil and a refigerator compressor I tore out
of an old mini-refigerator I had back from school.

It was working well keeping my computer's temp at least 10 degree's or more
cooler(initially it would be at 10-15 degree's celsius and ramp up to about
30-35. Without the cooling it runs about 45-50(with oil) which is what it
runs with just air cooling.

Anyways what happaned was the compressor froze the water(Which is pumped
through the oil using copper tubing) because the pump stopped
working(basically... it's pumping at it's peak height). I didn't realize it
was froze so I tried lifting the ice carriage thingy(basically the expander
that actually get's cold in the fridge) and it broke releasing the gas(maybe
I shouldn't say that... will I be fined or have to pay some type of carbon
credits? Hopefully I won't get arrested).

Since the computer is running a bit too hot I want to salvage the idea. (bad
enough it's in oil which is distributed the heat almost completely among all
the components)

Overkill. If you are running at 45C-50C you should be fine.

Most cpu's have a maximum temperature between 65C and 95C. The
problem is electromigration, which increases with temperature. But
if you are below the max specified, you should expect long life.

See the following for a brief list of max cpu temperatures:

See Chris Hare's "Processor Electrical Specifications" page for more
