My System Specs

Default Quiet folding

Hey guys,

I know it sounds like an oxymoron but I'm trying to get my rig to fold quietly. Now fan noise doesn't bug me, whats getting to me is coil whine. I've gone though about couple PSUs and Video cards trying to get a combination that doesn't whine.

I'm currently using two gtx 460s in SLI from MSI with solid chokes for no coil whine but every PSU I've tried SSCCRREEAAMMS while folding. My old PSU a corsair tx 650 would while so I got rid of that and got a xfx 850w (seasonic oem) and it screams too.

Does anybody have an idea on a setup that won't deafen me with high pitch noises?

you need to check juice from the wall, maybe plug it in a cheap (24$) line conditioner that may or may not already be included with your ups, if you have one.

and then,maybe focus on bigadv folding if the video cards are indeed the culprit of the wine.

i keep telling ppl to go with the hr-02 , very few do, even those that dont care about price tag and can accomodate its height in the case :)


check the passive numbers. munsta!

Too many random incompatibilities with the advanced C-states and quality PSUs, could try the new Antecs made by Delta though, haven't heard of compatibility issues there. (at least not yet)

Only surefire way would be to void your warranty, open up the unit and dab the coils with glue/resin.

I use Enermax Revolution+85 1050w, and Corsait 850HX, and get no coil while at all. I do get a bit on a video card, but its not bad.

I'm running 20k PPD using i7 920 d0 @ 4ghz 1.25v with -advmethods. bigadv deadlines scare me as I don't always fold 24/7. And the coil whine only starts when I GPU fold, also the frequency of the squeal changes with the shader clock of my GPUs.

As for the cooling I already have a nh-d14 of my CPU :) keeps around 65c with 19c ambient.

I might try getting a line conditioner and seeing if it helps.

well, then gpu folding is the best bet.

may have to play around with them, i remember on older g80/92 parts i had to up or down it by some mhz in order to make it inaudible, or trade the cards and be done with it


sorry, youve got already a good cooler :p

I had the core clock related coil whine with my crappy ULTRA psu but with the a cheap Enermax Liberty 620W I bought on the BST forum there is very little whine.

I would think that a better PSU would do it.

That being said, I use UPSes on both my rigs, which cleans the power too so I am not sure how much it helps. but I would say the PSUs I use are the biggest factor.

I got the best solution for the noise, house the rigs in a complex where all the residents share the power bill and my deaf Grandmother only complains of the heat they make :)
