Hi, I am trying to quiet my pc so far I have changed stock cooler to coolermaster 412s and its better but not great. i do not want to spend fortune so I am looking good value for money. Currently there are stock fans in the case(bellow description from oc)

- Front Cooling: 120mm /140mm fan x 1 (120mm Blue LED fan x 1 standard)
- Top Cooling: 120mm /140mm fan x 2 (120mm Blue LED fan x 1 standard)
- Bottom Cooling: 120mm /140mm fan x 1 (optional)
- Rear Cooling: 120mm fan x 1 (included)
- Side Cooling: 120mm fan x 2 (120mm Blue LED fan x 1 included)

there is my rig:

Motherboard: ASRock 990FX Extreme4
Ram: Corsair Vengeance RED 8GB
Procesor: AMD Piledriver FX-8 Eight Core 8320 Black Edition 3.50GHz
Cpu cooler: Cooler Master Hyper 412s
Graphics: MSI GeForce GTX 650 Black Knight OC
Disk: HyperX 240GB SATA3 3K SSD
Case: Zalman Z9 Plus Tower Case with Fan Controller - Black
Psu: Corsair Builder Series CX 600W V2 '80 Plus Bronze'

Gpu will be changed to Zotac 1060 in couple of days so I want to get some silent fans together with gpu.

Thank you for any advice.
 
The first thing you need to do is to think about how you want air to flow through the case. Generally, you want the air flow to help the heat escape - up and out. But you can have positive air pressure (air being pushed in) or negative air pressure (air being pulled out).

The second thing to do is to determine the origin of the noise. Is it the CPU fan? One or more of the case fans? The PSU?
 
Maybe wait till you swap out the GPU...see what difference that makes or maybe take one or two of those fans ( Bottom and Side fan ) away ?

Side intake and rear out make noise I have not checked top out and front in.
Cpu fan changed last week to coolermaster 412s.

There is no fan at the bottom its optional.

In general which fans are silent and not too expensive.

If youre trying to reduce noise i think you have too many fans, i have 2 intakes on front and 1 exhaust at back. Top/bottom/side all sealed to reduce noise.
 
The only thing that makes fans quiet is making them spin slowly.

This reduces the roar of air turbulence and motor/bearing noise greatly.

You can use software, built in controls in the motherboard bios for the fan headers or dedicated fan controllers.

Or you can buy fans which are permanently slow.

The downside is when spinning slow and making very little noise they move very little air and no amount of money changes that.

You want a fan to buy on a budget so get these:

That's a 3 pack so either buy two packs or get some singles too:

They run at 1800rpm which is an audible light drone no matter what fan and how much you spent on it, can be quieter depending on how muffled your case is.

So from there you need to look into how you can control the fan speed starting with what options are on your motherboard or what software will work for you.

Dedicated fan controllers cost money so probably not a good idea.

Anyway start by cutting their speed in half then fiddle til noise level is suitable.
