[Gllug] PSU fans

[George F. Saxby]

Guys,
 I do not know where you buy your fans I pay about £5.60, a whole power 
supply depending on wattage is  £15 - £30.
 As to soldering in a power supply fan leads seems you guys worked on 286' s 
last . They are two pin plug & socket jobs at least for the last 7 years I 
have gotten round to replacing fans rather than buy a PSu.
 	As to large voltages etc just disconnect from wall & the rest of the case 
to remove the unit lid. UNdoe the plug to the fan lead using long nose 
insulated pliars, undo 4 fan screws remove fan. Reverse the disassembly order 
to install new fan. same for PSU. Job done 12 mins tops from dead puter to a 
working puter.
