I picked up a stack of unwanted Compaq ( AKA duff ) 14" tft monitors
from a local computer store - all the same brand and model, but none
having power supplies.
Turns out they require dual voltage supplies ( 5 & 12v ), and it also
turns out that there's a page on the net detailing the adaption of a
computer PSU with a mouse cable to act as a power supply.
This I've done, and it works - and I've found that out of 15 or so
screens I've got 6 that work.
The question is; is it necessary to have the PSU fan running?
Granted, PSUs get hot, especially computer PSUs...but with the
relatively low load ( 2amps and 2.3 amps respectively ) is the fan
really needed?
Any opinions?
In the meantime I've rewired the fan to run on 7volts and all seems to
be well - and even after a full day running the PSU appears to be
stone cold.
