Power supply fan question


Apologies if this isn't the appropriate forum for this (since it's not really Linux-related). My box locked up today, and after some investigation I found that the case was about hot enough to fry an egg on. Turns out the power supply fan is dead; the PSU still works, but without a fan it'll overheat again. I can't really tell if a fuse is blown, but I only see one fuse inside the PSU case so I assume it's OK.

Anyhow, I have a couple of other PSUs with working fans. The PSUs themselves aren't enough wattage for my box, but I'm thinking of salvaging a fan from one of them.

Here's my question: Is it safe to use a 12V 0.15amp fan in place of a 12V 0.23amp fan? The amperage being slightly different, I wasn't sure if it could cause damage. If so, I will just have to see about getting a different PSU.

It is safe but I would guess the fan due to the smaller amperage rating does not output the same Cubic Feet per Minute as the original. And therefore may not cool the PSU as required.

A higher amp rating then the original may not be safe.

Thanks for the reply, but I also noticed once I looked around inside the PSU that one of the capacitors looked fried, so I played it safe and got a new power supply. The fans in my older PSUs are pretty dirty anyway... no telling when they would poop out on me.
