Seasonic 520FL2 Fanless Platinum whining!

So I bought one of the above a couple of years back after my old PSU gave up the ghost. Deliberately picked what I thought was top end for my needs - only running 1 GTX980 on a 2500k so don't need a 750W+ monster!

Annoyingly over the last few months its been getting louder and louder, which I guess is a form of coil whine, albeit coming from the PSU itself rather than eg the GFX card.

Any suggestions on what I replace it with? I guess it's still under warranty but it's going to cost £££ to send it off plus I don't have a spare PSU to use in the meantime (who does?!) and nothing having a PC for weeks isn't really an option :-)

Feeling a bit burnt having splashed out on a platinum model before, so maybe better going for a slightly cheaper gold model with one of those fans that only kicks in after a certain level? At idle my PC is 180W measured at the wall and silence is the most important factor for me.

Thanks for that. I'm wondering though whether a Prime Gold might be a better match since space in my case isn't an issue and it seems the Focus Plus range are a bit noisier with the smaller fan?

Alright, ordered! Looking forward to getting rid of this whine!

Thanks :-)

Just fitted last night and all good mate. It's fanless up to about 50% usage (300W) by which time my GFX card fans etc have kicked in and I can't hear it anyway! Just hope it doesn't develop a whine like the other one did but won't know that for a few months I guess.

In the meantime I think I'll RMA the old one once I figure out how to do that as would be nice to have a backup!
