Seasonic S12-500 Fan Modding

Can anyone tell me if it would be possible to mod the Seasonic S12-500 PSU fan? What I want to do is swap the stock 120mm fan for Black 120mm Yate Loon D12SL-12 , 47 CFM, 1350 RPM, 28 DBA. Would this effectively cool all the components inside the power supply? I have Enermax Liberty but I am trying build silent gaming rig with good ratio between silence and preformance so out it comes for Seasonic S12-500.

Why not the quieter S12-430?

S12-430 wont provide enough power for my use or esle I would use it.

It more than likely will.

Unless you're planning on quad-SLI and an overclocked Prescott with lots of HDDs 430W should cover your needs with plenty of headroom.

Regardless of what PSU you go with if you swap the fan watch your rails and if you have an IR thermometer watch the temps on the PSU internals. I swapped the fan out of a S12-380 for a nexus. It is the only fan in the case so I left it on 12v and did not hook it up to the internal controller of the S12.

Will the Yate Loon D12SL-12 even start at such low voltage?

The 120mm in my S12 was a ADDA AD1212LB-A73GL. 12v 0.24A.
Im guessing its min start voltage is higher than a yate loon. Most medium speed fans don't have a very low min start voltage. Of course there are some so dont take my word for all cases.
If you do put it on the S12 controller and it doesnt start at whatever voltage it powers up at from a ~25c room temp Im sure the voltage will shoot up pretty fast since its running passively
