Power supply fan going very slowly

post #1 of 20
Thread Starter 
Heya,

So I recently picked up this Seasonic SS-650HT off of Craigslist for $50, and it seemed to be running fine until I touched it to ground myself while messing around in my case and realized that it's running very warm.

Looking into the exhaust with a flashlight revealed that the fan is spinning really slowly (like one of my Noctuas at 40% speed).

What can I do about this? Is the fan replaceable?

its supposed to run slow. its a seasonic. if it needs to go faster it will.

mine barely spins when it does spin. most of the time it goes fanless.


also cant find any mention of a HS-650 anywere on google.

It's really warm though. I'd say a good 50* Celsius at least, on the outside, and the fan is still spinning really slowly.

And I got the model wrong, it's an SS-650HT.

Fortunex, if you had the Seasonic X650 model, the fan wouldn't even be spinning unless you were gaming. Be happy that you have the lower end unit that spins the fan all the time. As NKrader said, "its a seasonic." That's the way they are.

I have no idea about that model, but some designs use the casing itself as a heatsink for some components. Put a heavy load on it and see if the fan spins up more. It's likely okay, as people have been saying.

Ran Furmark and Prime95 at the same time, fan didn't seem to spin up more, although the PSU feels cooler today than it was before when I posted this.

If it's normal for these to run warm, then alright. Was just worried as neither my Earthwatts or Corsair for the brief time I had it got warm at all.

Thanks everyone

50c is not hot for a PSU as far as I know. As others have said, Seasonic's have a tendency of running low fan settings (because they can). I wouldn't really be worried about it, it's a Seasonic wink.gif

Any decent PSU built within the last few eternities or so have built in fail-safes which will cut the power if it overheats. The probability of both those fail-safes and the fan failing together (especially on a Seasonic) is astronomically small. Therefor unless your computer decides to start turning itself off, I really wouldn't worry about it.
