Antec Sonata PSU fan noise

to all the sonata owners, does your psu fan produce a faint clicking noise? i am thinking of replacing the fan with a panaflo L1A (japan).

update: after swapping with a new panaflo L1A (japan), there is still a little clicking noise. at first, when the power supply is still cool, there is no clicking noise. however, as the power supply warms up, the clicking noise starts to become noticable.
 
You want to replace the original fan with one of the same Amp rating or the internal speed controller might not be able to regulate it properly. You could skip using the internal controller and just hook the Panasonic up straight to 12V. Probably be quiet enough anyway. I got a stronger fan for my PSU and brought the leads straight out of the PSU so I can control and monitor the fan myself. But if you do that, be sure to hook the dang thing up to power! I pretty near smoked my PSU before noticing the fan wasn't turning... 😱
.bh.
 
Mine is not exactly quiet, but it doesn't bother me enough to actually change it. Now I've never heard a clicking noise from it either. You could always see about an RMA, because I don't think it shouldn't be doing that.

Click to expand...

you don't hear clicking noise even when you put your ear next to the fan? i've even replaced the fan with panaflo and the results were the same.
 
Ok, I held my ear up next to the PSU and I didn't hear any clicking. If you don't mind messign with an RMA, that is something you could probably do. Might be easier just to buy another fan tho.
 
My Sonata occasionally emits a very faint ticking sound, too. Usually lasts 20-30 seconds. When I first recognized it, I did some googling but didn't turn up any specific causes though it seems switching-mode power supplies frequently emit ticking or clicking sounds (it's unclear whether the ticking exhibited by the Sonata's PSU is the same thing, though). I assumed most people don't hear it because their systems or environments are way too loud (like I said, it's very faint).

Give us an update if you decide to replace your fan(s) and the ticking goes away entirely. It's not high on my list of concerns but it would be good info to have handy.
 
i don't think i will be able to rma since i already opened up the psu. :\ the clicking sound is definitely coming from the fan though, i tried stopping the fan and sound dissapeared.
 
Does the fan make that clicking noise when it operates outside of the PSU? Is there a wire against the fan blade?
 
there are no wires in the way. since the fan spins according to the temp, the voltage is turned, thus making the fan spin much slower. i think the fan spinning at a much lower rpm is what's causing the clicking noise.
 
WHY DO DC FANS CLICK?
"In traditional fans, the most dominant acoustic noise is due to the fan's motor switching noise. The stator motion is a square wave that is switched on and off before and after the peak torque position. This motion causes a small amount of undulation in motor torque, producing an audible noise caused by the lower frequency commutation operation. Each small torque causes a minute contracting of the entire fan structure and results in an audible clicking noise while the fan is operating."

According to SPCR's review, most of the noise emanates from the back of the Antec Sonata. Have you tried turning the computer case so the back of the case is pointing away from you?

Also, if your computer workspace doesn't need to be directly against a wall, placing the Sonata's exhausts so that they are essentially in free space really seemed to help me quiet my Sonata.
