Power supply fan doesn't work but PC does have power.

Client has a HP Pavillion 734N.  Power supply fan does not come on but the PC does have power and boots up normally.  Could it be anything other than a failing power supply that needs to be replaced?

Don't try to fix the fan in a power supply, unless you are familiar with observing safety precautions with electrical devices.  Opening up a supply can result in damage to the supply, creating a short, and injury to yourself.  You are better off replacing the entire unit.

You can buy a fan for the PSU, open the PSU up and replace the fan. Many PSU have a connector that goes to the unit... others are soldered and will have to have the wires reconnected... in the proper color sequence.

Other than that, it's only the fan that has seized and should probably be replaced.

"client" implies that this is your customer... if so... and this is not a shadetree fix it overnite.... whatever......................         why would you spend the time to remove the power supply, pull the fan (unsoldering the two wires... since these power supplies do not use fan coonectors), order a fan for these rather small power supplies, replace the fan, resolder the wires........... and send the unit back to the "client"...............              what are you going to warranty... the fan............. buy a new PS... and give the customer what they deserve..............
