What fan can I replace this one with? Answered

I've just took apart my noisy micro refrigerator, it's an insulin cooler that keeps medicine at a temperature of 2-8 degrees celsius. It's good apart from the noisy fans. Now I was confused when I took it apart as I'd never heard of a DC brushless fan before. So I'm now wondering what can I replace it with? Can I replace it with a standard fan that's the same size as it? Or do I have to replace it with another DC brushless fan of the same specs? I want to find a near silent replacement, will this be possible? Is it the fan that actually makes the noise?

Here's a few pics of the fan and motherboard:

Thanks, really appreciate any help.

Use a fan from a PC the same size and voltage, it should work like new.

They appear to be just typical PC component fans. Just get replacements of the same physical dimensions and voltage and you should be good to go.

Whether they will be quieter is another question. They make some "quiet" fans but you'll pay a premium for them.

Ok thanks, so what about amps? Does it need to be the same amount of amps? Also I don't know the RPM of the current fan and I can't find this info out, so what should I do about this? I wouldn't even know what RPM to guess the fan was?

They are all basically standardized, generally, if it fits, it will work.

Ok, so just to recap, I need to look for a fan with the same voltage and physical dimensions and it should be ok? If that's correct then that is my question answered, thanks.

As long as the fan only has two wires, you can replace it with another fan with the same voltage. Current should not be a problem. You may get it more quiet, if you can build a kind of funnel and use a bigger (diameter) fan. Bigger fans are normally more quiet than smaller ones as the turn more slowly.

Correct!
