Silver Arrow and Power Supply Problems.

Moothead2 · 17 Jul 2011 at 14:17

My first problem is that the Silver arrow fan in the CPU fan header on my MSI GD53 motherboard is always at 100% despite trying to change it in the Bios and with SpeedFan.

My second problem is that SpeedFan is saying my PSU (XFX 650w XXX Edition) is only outputting 10.47/10.56v on the +12v rail even when running Prime95 and FurMark at the same time. I know that software isn't the best way to monitor the voltage etc that the PSU is giving out (I'm sure my dad has a voltage meter or whatever it's called lying about) but that sounds very low to me, shouldn't it be around +-5% of it's stated output?

Anyone know if these problems are connected and what I should do. Both have only been in my system for a couple of days.

Thanks.

Don't know about the fan at 100% but for the +12v rail have a read of this thread.

Mine shows as 12.11V in BIOS but 1.22V through any software I've tried, so check BIOS and I would get a multimeter to check before taking the software as reliable readings.

As above, software readings of PSU voltages mean nothing.
Have you tried the fan on a different header at all? I'm not familiar with the BIOS of that board so I'm not too sure what options you have. Try changing the control mode in Speedfan or the BIOS from PWM to voltage control, see if that helps.

To put it bluntly speed fan is possibly the worst software i have ever known when it comes to monitoring temperature and voltage.

This http://www.cpuid.com/softwares/hwmonitor.html is a much better piece of softwre to use, if you don't have anything that came with the mobo.

I find SpeedFan fine for the temperatures, reads the same as Furmark and other monitoring/stressing software I've used. I've yet to find a reliable software program that shows my voltages correctly. I agree that there is more comprehensive software out there though.

i wouldnt read too much into voltage readings,

on my cx600, everest was telling me it was only supplying 8.56V on the +12V rail, i updated it to aida64, and now it is telling me 11.96V

Bios shows 11.9v and HWMonitor shows 8.18v

. Silver arrow fan works fine on another header, how do you change it to voltage instead of PWM?

Thinking of sending this PSU back anyway, makes a kinda buzzing noise and is just generally loud. the loudest thing in my rig.

BIOS sounds about right so the rail seems fine, no harm using a multimeter connected to the 4pin molex to check it. Again, HWMonitor is probably running in to the same issues in reading it correctly as speedfan had.

Check in BIOS that you have PWM management enabled (the actual name changes bios to bios) because that should allow the system to control it automatically through the original PWM header.

Not good to hear about the PSU noise

Often seems to be the case that it's the loudest component (or high end gpus under load).
