Also Need AdviceInfo on Replacing XPS P200s Power Supply

Usually, when you open up a power supply and examine the fan, you find that the wire leads for the fan are soldered onto the power supply's circuit board. If the leads are not soldered (rarely), then they attach with a connector not unlike the connector for a fan inside the chbuttis. Matching the connector of a replacement fan is a tricky proposition. So is soldering. What people do to replace a fan is to clip the wire leads near the fan, then splice the wires from the replacement fan to the wire leads, soldering and taping with electrical tape. The risk here is that the heat inside the power supply will eventually cause the electrical tape to come undone and a soldered joint shorts out and fries the power supply.

The foregoing explains why power supplies, not power supply fans, are replaced almost universally throughout the industry. The exception may have to do with old obsolete gear where there is little choice except to repair a failed unit.
