- I haven't yet needed to replace my fans, but what I would *prefer* to
- do is to crimp connectors on the fan wires such as I have seen before. They
- contain a socket to press onto the existing tab, and present another tab
- adjacent to it to accept the press-on connectors from the power supply. I
- intend to keep my eyes open for such connectors at hamfests and similar
- places.
-
- Lacking that, I would strip about 1/2" to 3/4" of insulation from
- the end of each wire, tin the wires (flow solder into them, so they
- effectively become a solid conductor when cool), wrap each wire fully around
- the each tab on the switch/fuse-holder assembly *at the base*, and flow the
- solder into this joint, with the position of the tabs such that solder does
- not run down to the ends. (The excess solder would make the press-on
- connectors for the power supply difficult to get on and off.

- The only benefit that I could see to this arrangement would be that
- you could run the fans for a while after powering down the computer, to cool
- off the interior more quickly. Since the system should normally be left
- powered up in the absence of adverse conditions such as thunderstorms
- playing outside the window, or smoke exiting the box :-), this would be a
- minimal benefit for the additional inconvenience of having to find another
- power outlet for the fan, and having to live with a permanent power cord to
- the fan(s) when moving the system, unless you took the time to mount a
- separate jack for the additional power cord while modifying the system.
-
- You could mount the new fans on a cradle for the cpu-box, which
- would hold them against the existing ventilation openings, in which case
- having an extra power cord for them would make sense. They could also be
- inspected for excess dust buildup more easily, and replaced easily in the
- unlikely event of failure. The negative tradeoff here would be reduced
- access to the connectors on the back of the computer.
-
- Good Luck
