Are PSU fans replaceable?

Typically, it’s a simple 2-pin or 3-pin(less common) power connector(soldered wires are pretty rare these days) and all you have to do is disconnect it (it’ll have small tabs holding it in so a little force is required) and replace the fan.

How do I test my PSU fan?

Locate the 20+4P (24-pin) connector. Bend the paperclip and insert one end into the green pin (PS_ON) and the other into any of the black pins (Ground).

Should you replace a dead fan or power supply?

It’s worth noting that if you’re, say, replacing a power supply fan, you should instead buy a whole new power supply.

If you have a fan that’s dead or dying, the answer is to simply replace it.

Which way should the PSU fan face in a PC?

Almost all these PC cases have vents at the bottom where the PSU fits and most of them have dust filters installed at the vents to prevent the dust from getting to the fan and PSU components. So, if you have such provision then the PSU fan should be positioned downwards.
