Title: Noisy RM850 on a S5 Post by: VirosaGITS on May 15, 2016, 06:47:14 PM I have a S5 on a RM850. First the fan does not spin. And second it make a electric buzzing which is pretty annoying. It sound like an electric clipper, albeit with a lower dB.
Is this normal? Also at 393hz i estimate the draw DC to be over 600W. I would have thought the fan would spin.

One little design flaw so minor that it affected exactly zero consumers, and suddenly Corsair is the devil to some and now the RM series is crap not worth buying. Granted, some of these people are still reasonable, not holding the company as a whole to the torch just because the RM or the CX series turned out to be below their personal standards of awesomeness. But for every one of the reasonable people, there's another one coming out of the woodwork with nonsense like, "oh, I'll never buy a Corsair again because the CX750M shuts down above 30 degrees and only crap units do that." the original "bad" rm850 vv http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=369 Title: Re: Noisy RM850 on a S5 Post by: VirosaGITS on May 15, 2016, 07:14:53 PM I have a S5 on a RM850.

But if you're saying all the RM850 are like that... But no one in the reviews mention this noise, that i can see.

I was wrong though, the fan didnt spin at 350mhz. When i raised to 393hz it actually started spinning but its very slow and not really something nice for ambiant mining condition. Anything about the noise being normal? I was thinking of using the RM850 for a secondary PC, i'm only using it for a S5 temporarily, while i get a PSU RMA. But there is no way i want a "silent PSU" make a clipper noise in my backup PC. Title: Re: Noisy RM850 on a S5 Post by: Unacceptable on May 16, 2016, 12:54:49 AM That PSU is a P.O.S. I have one just like that,I have a new fan to solder to the wiring since there is no plug to pull to swap the fan ::)
Not sure if it will work even then,I think there is a fan control board,it may be bad...not sure yet............ Looking forward to you solving this 8) Title: Re: Noisy RM850 on a S5 Post by: adaseb on May 16, 2016, 12:56:18 AM You sure its not coil whine? Some PSUs with some miners or GPUs having bad coil whine.

Well it does the noise even before the miner start mining, at minimal load. And it shut down itself after a few hours, now.

On newegg getting a replacement is really easy on RMA in most cases. Not sure how easy it will be to get a flat return though.

It was refurbished so i'm not quite sure what they will send back but i hope i have some kind of revision with the RM850 fixed, otherwise i won't be able to mine much with it heh.
