Some of these fans can be re-lubricated with a single drop of oil and make them quiet again. Did you try that with the original fan? Replacing the fan was just unplugging the old and plugging in a new one? Or did you have to re-solder connections? Did you take any photos? Yes, I tried oiling the fa...

Just thought i'd throw in this one:

What's with those posts? Anyway, I put a Scythe 1600rpm into the "voided" S12II and I'm now using it in my secondary rig, that has pretty low power draw. I actually went all out and got a X-750 for my gaming rig, and wow, the fan never even turns on even at full load (only for a few seconds at power...

I tried a Scythe Slipstream 1600 rpm and 1900 rpm, and some Noiseblocker fan (which isn't great anyway). I measured the voltage at startup, and it is just above 3v, the S-Flex 1600 has a starting voltage of over 4v, so I guess that it would have the same problem? On the other hand, the PSU would rai...

That sounds very high. How did you calculate that? You're right, I measured the power draw at the wall socket to be around 360w at max load and forgot that the actual wattage drawn from the PSU is lower. So taking into account PSU overhead, it should be at around 300-310w in extreme situations. May...

So I tried replacing the fan on my Seasonic S12II 520w, since the one built in was getting noisy. However none of the fans I tried as a replacement would spin up at the low voltages the controller feeds them. Since I thus successfully voided my warranty and can't find any sources to buy another ADDA...

I have never owned Scythe PSU, but I modded my Seasonic S12 (changed a Scythe fan there) and got it quiet... If I may ask... what Scythe fan did you put into it? I also thought about this but feared that a more silent fan would be too weak causing the PSU to overheat. I got a S12 II 520w and since ...
