Silence seems impossible, help? - Page 2

post #11 of 34
Most reviews of high end computer components are done by gamers who generally don't have sensitive ears in the least. I'd go to a site like silentpcreview.com for psu recommendations next time. 7volting even the loudest fans will usually bring them under an acceptable level but go through your fans and slowly stop them individually with your finger or the psu with the pencil like Zap described. I'm quite sure it's probably the power supply.
Seasonics are generally the best regarded power supplies noise wise and corsairs which I think are now made in house (not sure?) but used to be rebranded seasonics as well. My corsair ax850 is known for being extremely quiet until it hits about 400w load, in fact the fan doesn't even start spinning until like 170watts load.
Any of the seasonics in the X series are absolutely supreme in terms of noise output.
I'd look at those if it turns out being your power supply.

Sound dampening foam doesn't make a lot of difference. Sound dampening relies on mass and directional and absorption properties. The price computer sound foam is sold for is ridiculous for the literally 2db maximum it's going to bring you in performance. It's true it might reduce overall turbulence but for something cheaper you can go with some kind of mass loading material like vinyl tile i've seen used in the past or even the sound absorption foam studio engineers use on their walls. Still I don't honestly think it makes hardly any difference.

replacing the psu fan isnt all that hard really, i did it on mine quite easy.

you dont HAVE to solder the fan back to the psu outlet, you can run the fan cable through with the rest of the cables and attach it to a standard molex.

or if you plan on never using the psu fan ever again, just cut the wires half way, splice them with the new fan, tape em up.



I did it with my psu, the fan simply connects to my mobo's 3pin tongue.gif

Corsair doesn't make any PSU's in house. It's still just Seasonic & CWT Mostly (AX1200 is Flextronics though.)

Corsair's AX750 & 850 models are the same as the Seasonic X-850 & X-760 units.

One of the best units in terms of noise is actually the Kingwin Lazer Platinum 550w which doesn't make a peep, even up to 400w loads as the fan can stay off under most conditions until the internal temp hits around 45*C IIRC
EDIT: It helps that the unit is an underrated 700w unit.

Thanks for the correction Tator Tot. From what i've read it seems most psus are just rebrands but it's hard to keep up with who is made by who.

The PSU Review Database here can help you at least know who the OEM is of reviewed units. (It's a sticky in the PSU Section)

Stay away from the Nexus. Poor DC output quality for the cost.

Out of the two you listed before, the Silverstone Strider Plus would be the quieter of the two. The OCZ would be the better performing of the two.

Thank you for the advice, when you say better peforming i tend not to find performance an issue with my thermaltake thoughpower xt 775w and they both would be classed as better performing than that i assume?
I'm just slightly confused as to which support crossfire and which dont.
