PSU fan.

[adham.]

So i got a new PSU and i didn't have any header left for the PSU fan and the PSU fan is running 100% ?
Normal ?

P.S: i'm getting a fan controler but just to be sure that if it left unplugged PSU fan would go 100%.

The fan in the PSU is controlled by the PSU temperature, not by an external fan header.

How do you know it's spinning at 100%?

Super loud fan. And there is ton of air coming out of the PSU.
Voltages are stable and good. And i'm idle. (not running anything)

which psu is it?

Bitfenix BPA 600W.
I know it's not the greatest but got it for super cheap.

For how much, you should have gotten something better, the fans max because that PSU is trash.

Not trash per say but it's on the more cheaper end.
Though it's good in heavy work loads and gaming and voltages are good.

I got it for 60 US dollars. (this is considered good in Egypt due to the dollar being almost 18 EG)

the noise is not surprising. Even the marketing material says 730rpm constant upto 80% load. https://www.bitfenix.com/global/en/products/power-supplies/bitfenix-bpa/

for comparison the Be quiet straight power 11 are around 250 rpm with better fans.

Oh.. didn't see that.

Maybe that is what you get for cheap PSUs. 

Thanks.

What loader and voltage meter do you use? SunMoon, Chroma?

Sadly i don't use any of that stuff, I mostly use software like SpeedFan and others.

I know they are not the most accurate thing in the universe but they have pretty good reading for what i can tell.

Then we can't have any idea of your voltages and if they're loose or tight. Software readings may as well be taken from a random number generator.

 

The CWT GPM platform inside your PSU doesn't like transient loads from modern graphics cards, so there is a chance you will have problems running things like a GTX1060 or better.

 

Anyway, seems like the PSU's fan is designed to run at high RPM until the max load, where it runs even faster.

I know that software isn't accurate but as i said it give you at least somewhat of an image to see if you have a problem with PSU.

No.  It's trash.  I mean... You could do worse, but not by much.

 

The fan is supposed to be thermostatically controlled.  But the cheaper components used within means that if ambient temps are anywhere over 25°C, that fan is going to go ape shit.  The PSU itself, due to its inefficiency, is going to create a lot of its own heat.

 

You can assume that the fan controller is defective, but my guess is it's just the nature of that PSU.  It's not known to be a quiet unit.
