How old is the PSU? To me, that sounds more like a dying fan. Your unit uses a Fluid-Dynamic Bearing fan, and that sounds very much like what I'd expect if it was starting to fail.

There are three types of fans. Sleeve Bearing fans are the cheapest, and are just two surfaces with some grease between them. They have a short life because the grease dries out and then the bearing gets very noisy or fails. There are Ball Bearing fans, which are a tried-and-true, bulletproof design that lasts a very long time. Main downsides are that they are more expensive and not as quiet. Finally you have Fluid-Dynamic Bearings. These are basically an advanced version of the Sleeve Bearing, where instead of a bit of grease there is actually a layer of fluid between the contact surfaces, along with grooves that circulate the fluid during normal operation. In theory, they should have the longest life, because the surfaces should never come into contact, so there is nothing to wear out. That is compared to Ball Bearings, which while very reliable and long lasting, still have contact surfaces (the balls) that will eventually wear out. Fluid-Dynamic bearings are also the most quiet, since again, you should have no surfaces that are in physical contact with each other. The catch is, while a fluid-dynamic bearing can have a very long lifespan in theory, in practice they have a much higher failure rate than ball bearing fans. If any of the rubber seals wear out, the fluid can leak or dry out, compromising the bearing. They are more sensitive to high temperatures, and they are also more sensitive to fan orientation, with horizontal placement sometimes causing significant lifespan reduction.

i put the action cam i have at the back of the psu on the kettle lead it still does not pick it up very well but i can hear it .

i just dont want to rma this thing and get another that is the same and makes a buzzing noise.

i have never had a psu make this noise so cant be right ?


at about 30sec i run cbr15 and the pitch of the noise changes and speeds up still hard to hear tho

the psu is brand new but the vid does not pick up the sound it is making very good but it is defentley coming from the power supply.

https://forum.corsair.com/Forums/showthread.php?t=134860

it sounds like crickets inside the psu it is not very loud but it is annoying and the psu was not cheap either.

The "cricket" sound is likely coil whine, which is normal. You might be able to RMA it, but there's a pretty good chance they'll send it back to you, or send you another one that does this. It's almost impossible for the hardware manufacturers to completely eliminate this, since it's so variable based on exactly what the PSU is powering, and what the system is doing.

If you really can't stand it, you might try to return this PSU and get a totally different model, with the understanding that every power supply is capable of making this noise, and it's not indicative of a defect.

Definitely could be coil wine, as it is indeed difficult to tell from the video. It still really reminds me of noise caused by a bad fan, and it would make sense that the noise would change 30 seconds after starting a benchmark as fans in a PSU are generally thermally controlled and will change speeds as the PSU heats up.

It would be easy enough to test. Power the system off, stick a plastic object through the grill that prevents the fan from spinning, turn the system on (briefly), and listen for the noise. If you still hear it, then obviously it's not the fan.

i dont think the psu fan was even spinning but i can hear it sat in my chair so it is getting annoying.

ill try a different adaptor or plug the psu straight in to a plug socket and see if that gets rid of it.

if not ill have to rma it and look for another brand psu

I actually have an RM1000i, and it does not do do this.

If you really, really, can't stand the coil whine from this power supply, which is understandable, then you'd probably do well to consider a power supply from a manufacturer other than Corsair. I'd bet good money that the design of the RM1000i and the HX1000 is nearly identical.

Does it make this noise when it's just idling at the desktop?

yes it makes the noise just doing nothing ill try turn the fans down so can hear it a bit better but need to move a 18u rack full of equipment to get to the plug socket and try changing that first.

i am in the uk but would using 230v from the wall be the cause?

no. its just coil whine and is normal. some people are more sensitive to its noise and some products make more that others.
i have had a fair few psu over the years and none have made a noise like this i can hear it 2 feet away sat in my chair, if this is normal for these psu then i dont want another one which is a shame but i cant stick this noise it is making atm.

didnt someone already tell you to get another brand as corsairs are notorious for this?

yes but if i send it back i wont have a computer, this psu was for my new threadripper build but i can see loads of posts on the corsair forum for the same issue.

im trying to get my old psu recapped first stick that back in this system so i can then send this thing back to scan.

you should probably just get a new psu and send the corsair back, like someone already said too. the old one is ancient.

so is this rig lol but ill try a new adaptor direct to the wall and see if it goes away and if not ill get it sent back and get a different brand for the new rig.

i just thought if i can get the old psu working again for 40 quid it is going to be cheaper than buying another psu for it with dual 8 pin cpu power.

maybe but why risk you new hardware with an ancient psu?

Anyway you can get scan to cross ship your new psu?

no idea as not contacted them yet but will ask if that is a option or not
