Huge heatsinks such as are usually your best bet to avoid or reduce the need for noisy fans try NOFAN for their CPU cooler and there are high end graphic cards such as Powercolor's Radeon HD 6850 1GB GDDR5 which are fanless.

You'd also be surprised how much noise optical drives and hard drives can make, so grab yourself an SSD (better performance plus less noise from moving parts) and an LG CH08LS10 Blu-ray drive.

If that doesn't help, or you want a cheaper alternative, invest in some Acousti Soundproofing.

Your best bet is to replace all the case fans with high end ones and check the dbm ratings.

Also, make sure you get decent quality Power Supplied and CPU Coolers. Research them first.

Or in some cases you might not even need case fans. I have a small MicroATX server and with the Core i3-2120 I need no case fans.

You can try water cooling, its queit and good for cooling down your pc.

And destroy his CPU? Good advice, man.

As long as the temps are low you don't need fans. I have a few systems that run just fine without any fans other than the CPU fan.

He said no fans at all. That's just horrible advice.

I have 3 computers with no fans. If you knew anything the motherboard would turn off before the point of damaging the CPU.

"no fans" is not necessarily a bad advise, BUT only if it happens to involve water cooling. Of course if Zorbeen is building his own computer, he can make use of various water-cooled installations. here are some not-so-expensive examples:

Yea i knew that. Who wants a computer that randomly shuts off? If you knew anything you wouldn't run 3 computers with no fans.

Get a case with HUGE fans like the cooler master HAF X. Big fans spin slower so they make less noise.

the fans and hard drive is about all that makes noise. get an ssd and high end fans and you won't be able to hear anything. an hdd isn't that loud though. decent fans should be fine. big fans in good spots so you don't need as many.

it depends on how much your wanting to spend on getting a near silent PC.

some indipendant and online computer stores sell cases and make sound proofing foam for certain cases, some cases come with acoustic foam already in the panels.

the main thing in my case that makes the most noise is the HDD's when the computer is on idle, you can get silencing box's for them, but there not that good as they heat the drives up.

a water cooling system would be better for the graphics card, they can get loud, especially if you have an SLI or crossfire setup. acoustic foam or an aftermarket cooler or water cooling is the only solution.

after this the CPU fan, get a good heatsink and fan that is built to be silent.

but in my case after the GPU's fan, it's the PSU fan, when under load, it starts getting quite loud, even though it's a Corsair PSU, it does get loud, so i recommend getting one that is 100-200w or more over the power your going to be using.

the problem with a complete or near silent computer, you will hear the high pitched squeal of the GPU, GPU memory and your RAM, you will hear like a cricket squealing.

The case is impotant, without good cooling it's going to heat up and make the fans have to run faster and so louder. 120mm good quality intake and out take fans are important, along with a fan speed controller for when the system is on idle and you can put them at a slower RPM.

The case it's self has a large impact on the overall noise on the system. If you get foam padding for the case eg http://www.newegg.com/Product/Product.aspx?Item=N82E16811999222

you can significantly reduce the noise (PS don't buy the foam designed for cases, they are insanely overpriced (get foam from a hardware store (the kind with foil or plastic on one of both sides (common fir siding insulation)

then look for some double sided tape and cover the panels evenly with the tape (the tape and foam stops the case from vibrating and acting as a soundboard.

Other than that, make sure none of your fans are smaller than 120MM (with the exception of the videocard)

I was taking a look through youtube. And found something that might answer your question in general for a quieter PC Its from NCIX tech tips. This might help out as well for you.
