Default what 120mm replacement fan for a Mios 545W PS ?

Hello guys , my 1st post on here and I have told my youngest son about this site as well since he likes to build and modify his own PC's so I expect he will join up .

Had the fan in my 545W Mios power supply hit the crapper ( bearing/noise/laboring ) and want to replace the 120mm fan . It's 12V of course but I'm wondering what CFM range I should be looking at to move enough air . PC doesn't get overworked so I doubt in the PS is doing much more than idling most of the time . The Mios 545W replaced the original PS which blew a couple years ago and was only a 350W .

Thanks !!

Hi and welcome to the forum!

Just about any silent case fan will do for a power supply. there's no need for a high-cfm and/or high static pressure fan in these situations. Beyond that is up to your preference. Some people will suggest using a Noctua fan, but i find they look like dead fish... lol. It's really up to you.

Personally I'd suggest buying a new, high quality PSU instead. I've never heard of this brand and if the fan died, there could be other faults with it.

I'm going to agree with jdrom, a new PSU would be worth the trouble.

I'd vote for the new PSU as well, but if that's not in the budget, this first thing you'd want to look at is the original fan. There should be a label somewhere with a model number that can be cross-referenced to get an idea of what the manufacturer thought was needed. You'd be surprised at how strong some older PSU fans are, simply because their efficiency was so bad, and heatsinks so flimsy, that they actually needed something pretty powerful to keep temps down.

Could always grab a cheap Yate Loon and throw it in. Chances are it will work fine even w/ a low speed fan.

Got an S-Flex 63CFM today and installed it....works great .

Yes I could go out and get a high end PSU but we arn't talking a high end PC here guys , it's my 6 year old Gateway pentium 4 beater .

The Mios 545W PSU is a low end unit , no hell but built better than a lot of crappers out there so I felt it was worth the fan .

You could have bought a high quality psu as the first component of a new build!

If I put any up grades into one of my PC's it will be my XPS 435mt , the old Gateway is just for regular use . The only mod it has had is a GeForce 7300GT my youngest son put in it for some games and this MIOS 545W psu .

With both my sons in the military you can imagine they like to play a number of military theme games but my youngest and his wife now live in Edmonton .
