I read an article over at SPCR, whereby the reviewers PSU had the thermistor 'glued' to some component that inevitably got hot as part of normal usage, and so, once the PSU had been on for say 10minutes, the fan sped up, and it would stay sped up, regardless of temps inside the PSU.
I get the distinct impression that this is happening with my PSU aswell, it's a Hiper 580w. (they're fairly reputable in the UK, it's ain't no Ultra P.O.S!)
My reasons for thinking this are that although it does stay quiet for some time, eventually the 80mm fan ramps up (can be made to ramp up quickly by generally increasing case temps though...?) and then just will not go down again.
The PC was on overnight, the room temp was about 18degrees, CPU at 29/30, hard disk at 32, motherboard reading at about 23, basically, everything is frickin' freezing, I put my hand behind the 80mm, and it's blowing out cool air from the PSU, but alas it's still running away at 2,500rpm.
I've had a look around inside, and can't see anything obvious, so was hoping, somehow, someone knew where it is? Or had any tips on helping me find the bastard.
My other options are to remove the 80mm and just let the 120mm in there do its job, or to get a resistor in there to limit how fast it can go.
In another article, the topic of two fans was discussed, and gave me the impression that perhaps that 80mm is just in there in case the 120mm fails, and that it probably isn't helping airflow, and may well be limiting it? Given that about 30mm of the 80mm fan is sucking air directly from the side of the 120mm casing, I don't think it's really doing a whole lot, any thoughts?
For reading that, have a
on me.
OK, that was long, cliffs:
-Where's the thermistor in my Hiper 580w PSU?
-Any ideas where it might be if you don't know?
-Given that 30mm of that 80mm fan is just sucking air from the 120mm fans case, and is probably pushing much less CFM than the 120mm fan, would I be better off removing it altogether? I'm definately thinking get that sucka outta there at the moment, but would welcome some advice.
Thanks very much.
