My Power Supply Fan broke

[Nibber]

Today, i accidentaly broke a wing from my psu fan and now it cant spin, is that a problem that i should take care of ?

[OrionFOTL]

Yes, power supplies need working fans (believe it or not).

 

If it overheats and has proper overtemp protection it will shut down, and if it overheats and doesn't have overtemp protection something will blow up.

[TheKDub]

Yes. IIRC some power supplies have a normal PC cooling fan (I'm not sure what size, might vary depending on the model and brand), that you can remove and swap out.

 

 

Skip to about 3 mins in if you just want to watch the fan replacement part.

This youtuber's video is bad advice and potentially very dangerous for anybody who tries it. The original fan in his PSU is a strong 2800RPM, 140CFM one. He replaced it with a quiet, but weak 120RPM / 68 CFM fan. The power supply makes less noise, but receives much, much less cooling than it needs.

 

PSU engineers know exactly which parts of their PSU get hot, and give them appropriate fans, sometimes at the expense of noise. If they could put a slower, quieter fan in there and still have it not overheat, they'd do it. Replacing it with a much slower one is depriving it of airflow that was deemed necessary by the engineers, and can have extreme consequences.

And that's his own problem to deal with.

 

I'm not saying that OP should use some super low RPM or low airflow fan. I provided the video to show the concept of swapping out the fan.

 

Also, just because the original fan on that power supply is capable of 2800RPM and moving 140CFM, that doesn't mean that's the speed the fan actually ran at. (That'd be an incredibly loud power supply if it did run at full speed).

 

The OP has two options: 1. Replace the broken fan. 2. Replace the entire power supply.

More likely than not, replacing the fan will be many times cheaper than replacing the power supply.

If overheating is a concern, then just be sure to use a high quality fan that's capable of moving plenty of air, such as an NF-A14 iPPC-2000: https://amzn.to/2VPwm6v

2K RPM, roughly 110CFM, or even an NF-A14 iPPC-3000: https://amzn.to/2YDMSmL 3K RPM, 160CFM. Just be ready to wear headphones if you want to hear anything other than the fan, since it'll be hitting around 41dB while moving all that air.

How can we recommend anything without knowing what PSU is the one with the dead fan??

If you give advise and don't mention the dangers, it may as well become YOUR PROBLEM! 

Especially if someone dies -> https://www.dailymail.co.uk/news/article-2215200/Teenager-Shawnee-Oklahoma-dies-electrocuted-fixing-computer.html

You recommended a dangerous procedure, wich might lead to a fire or death of a person, without mentioning any dangers of that procedure...

No but it means that the Power Supply is certified with that fan.

With a different fan you change the specification of the PSU.

Meaning that it doesn't do the rated wattage at the rated temperature no more.

And in case of the EVGA you've shown, its possible that OTP is not implemented either. That then means that it can get over 200°C before something burns. And if the PSU is dusty, that might cause a nice fire.

 

You are really underestimating the dangers of power electronics...

Yes and we should always recommend the ones that is better in the long run and safer.

We must NOT recommend something that could lead to some serious damage, injury or loss of life or the house.

 

And a good fan can cost 20€, a somewhat OKish PSU is 40€.

No, it won't.

And we don't even know what PSU he has!

Is it one of the 5€ ones?
Is it already 10 Years old?

 

Without that knowledge, how can you recommend to replace the fan?

 

Or what about Enermax PSU? With their 3 pin proprietary connector. You can't just replace the fan.

You recommend a fan for 28€, when a decent, new PSU can be gotten for 40€:

(only one PCIe Connector)

or one for 45€:

And if its a Cooler Master Real Power, that fan doesn't make any sense either...

What PSU?

How old?

pls post the exact model number.

What happened?

Is still under warranty. 

 

But it's also a garbage PSU.  Return it and get something quality.

lol not saying is not garbage but do you know something about romanian psus? or what made you think it's garbage

Its garbage until its proven to be good.

 

Simple as that.

Especially from unknown brands.

 

Or are you trying to say that MS-Tech or LC-Power does usually do quality PSU??

That's NOT a 500W PSU.

 

That's really a 372W PSU on the 12V.

 

Yeah it's garage, needs to be replaced.

There are no reviews. It is garbage until tested. We treat even SeaSonic, and Corsair PSUs like that.

I'm not trying to say anything,you're assuming something i did not said.Just because a product isn't tested with a review , doesn't automatically mean it is bad,you can chose to be sceptical on its quality and that's understandable.

''It's garbage untill proven to be good'' / ''It's good until proven to be garbage'' same logic applies.

No, but its more probable that its bad than that it is fine and a good quality product.

In most cases stuff doesn't get send out because they know that it would look bad in a review. For example all those EVGA Bronze units.

No, its not the same logic.

One is to be sceptical, the other is to trust something blindly.

That's a big difference.

 

Especially regional brands that do cheap stuff are something to be sceptical about!
Here in Germany we have a ton of cheapo manufacturers, that also do PSU. For example: Ultron, MS-Tech, most of the Inter Tech stuff, LC-Power. 

They are all pretty bad (some do have some promising stuff but its yet to be proven good).

 

Some other cheapos went under or got bought out. For example Rasurbo, Xilence. The latter one is now owned by a quality manufacturer and used as a cheap brand but their products are cheap but pretty decent.

Others that you might or might not have heard about: Tronje, Kiss Quiet, Codegen (wich I particularly really intensively dislike).

 

Yes, there are some companies I trust more than others, because they have proven to be rather trustworthy and doing good products,

Others I don't trust because they either have a totally insane product lineup that even I can't keep track of. 
Or they have been proven to be either bad or just not interested in making good products at all.

 

International PSU Manufacturers I'd stay away:
Tacens (Spain)
AeroCool, CiT, Linkworld, LogiLink, Xigmatek and a couple others.

 

Some Manufacturers have some decent Products that are good, for example FSP, InWin, Thermaltake, Silverstone) but some of them are less good (usually the Bronze ones)...

 

Remember: TRUST is earned, not given!

If someone enters the PSU market, they have to prove they are to be trusted, that they do want to make good products and that they are competent to make good products....

Some of them destroyed every trust I'd give them, some other didn't.

Not just that, but it's 230V only, so it has an undersized primary side.

There's usually a good reason behind no reviews. You'll usually even find SAMA PSUs, a tiny manufacturer you've never heard of, on review in both English and Chinese language PSU publications. At least, their good units, like the ARMOR Gold and Forza Titanium.

 

Meanwhile, EVGA doesn't send their shitty units out for review, same with SAMA's low end units. There's a reason behind that. They're bad PSUs. It would make them look bad in the press.

 

Without a review, it's bad.
