Want to try cleaning or replacing PSU fan for P03-600...HELP!!!

kslibra

Per other discussion, I want to try cleaning or replacing the fan in my PSU (since Acer made it nearly impossible to replace!). I've watched YouTube videos - frightening, as it seems I can electrocute myself - but all of the videos are 24 pin. How do I discharge on the PSU for the unit that came with the Predator!

TBH, sticking tweezers into those pinholes freaks me out, but it's worse when the video doesn't match my product. So...(1) is there an easier way to discharge, and (2) if there isn't, can someone give me instructions/pics on how to do it with this particular PSU?

Thanks a bunch.

The PO3-600 desktop has a 24pin PSU, so first take the PSU out of the desktop case and take it to an experienced technician in your area so that he/she can change the cooling fan for you. Note: the PSU cooling fan does not work with high voltage that the voltage is lethal in any way if you touch any of the fan connecting wires, as the fan wires will not electrocute you.

The components of a PSU that will electrocute you are Capacitors of the primary repositories of charge in an unplugged PSU and they are specifically as follows:

• Large capacitors, often used in a “half-bridge” arrangement, can hold significant charge. These capacitors are designed to switch between nominal 230 VAC and 110 VAC easily. If you were to touch them, they could be lethal. Fortunately, most PSUs are designed to discharge these capacitors within seconds or minutes after being unplugged.
• Smaller capacitors across phase-neutral (X caps) and from mains lead to ground (Y caps) may also hold charge for some time. While they are unlikely to be lethal, they can still cause discomfort or injury if mishandled.

DO NOT CHANGE THE PSU COOLING FAN YOURSEF especially if you are inexperienced and have no idea what you are doing, get a local technician to change the cooling fan for you as its a very simple job and not expensive. Good luck.

The chances are pretty good that if you are hearing a of of fan noise, it's not the PSU. Typically the noise comes from the CPU fan on the motherboard. The PSU fan is fairly small and doesn't move as much air.
