Making my computer quiet

Hello guys

I started to build my PC and encountered a "problem". My PC was very noisy.
So far I changed my CPU cooler to Xigmatek Dark Night 2 ( it keeps my FX 8320 stock at 33C on prime 95 with rear exhaust fan turned on regarding Core Temp) and I found 2 issues of noise.
First of all I had disconnecting the rear fan as it was running from a molex (it came with my Zalman Z11 Plus case). Is there any way to control this fan for example with a fan controller or they are for PWM fans only?
After that it still was reasonably noisy. My front fan and top fan ( same type, stock fans PWM) seems reasonably quiet.
My PSU although is seems to be noisy. I am not sure because it is bottom mounted and as there is a small place to suck in air, it might be the reason for noise, this is my first bottom PSU case
And other question: My PSU is a pulse unit from dabs. Yes, the cheapest ones and it is 550W
I am looking for a new PSU in several weeks. It should be around 550W ( planning to get a 280X later on as prices will go back to normal or maybe a GTX 760/270x), if modular the better ( for blue braided cables :) ) and should be reasonably quiet. I am stuck between the non modular but 58A@12V XFX Core PSU and CM 600 Modular(48A@12V if I remember well) but I am open to other options, around this price

With this build I am looking for a reasonably quiet build and I know that there are better/quieter fans around and passive cooled PSUs but they cost a fortune

Here's a cheap simple fan controller:

No need for pwm fans if you go down the fan controller route as most control fan speed via voltage not pwm.
I'm sure there are fan controllers that can control with pwm but i'm sure they are more expensive.
Pwm fans are good if your motherboard has pwm fan headers.

Any good quality psu should be relatively quiet.
I personally recommend corsair psu's, but anything from cooler master, antec, xfx or seasonic are good choices too.

and what is that? is that a resistor, so it will get less power= less noise?
I am not sure if I should get it as my CPU cooler is quiet enough and cools extremely well
I am looking for my 4 pin molex fan mostly, is there any way to control that?

Is asus` fan controller a good program?
I got it bundled with my M5A97 EVO, and it sets the fans by the temperature of... something (probably socket) and I can set the fan curve
It shows 20 degree more then core temp and 10 degre more then HW info socket temp. why? should I use different programme?

There is 2 temperatures to monitor when it comes to amd cpu's
First of there is the cpu/package/socket temp (different name depending on what program you use), this is usually the hotter temp out of the 2.
Second is the cpu core temps (again can be called different things depending on what program).

Core Temp as far as i know only reads the cpu cores itself so obviously that's named correctly.

HWiNFO (i've not have much experience with this program):
(I have a Asus Sabertooth 990FX board with it's extra sensors so this might effect these readings compared to yours)
The temps listed under 'CPU [#0] AMD FX-8320' are actually the cpu core(s) temp (hwinfo lists these as 'package' temp which is wrong)
This temp should also be close to the temp that Core Temp reads.

The cpu temp listed under ITE IT8721F (again this might be different due to different boards) is the cpu socket/package temp.


I would suggest using AIDA64 to monitor temps as it reads temp sensors correctly (at least it has done for me as long as i've been using it)
Here's a screen shot with a few different temp monitoring programs:

The temps in red is the cpu/package/socket depending on what you want to call it
The temps in blue are the cpu cores (mine are all different because every program updates the temps at different intervals, i couldn't get it exact)

Fans... As long as they are all 3pin or 4pin (pwm) fans you should be able to control them with the Asus software.
If they are 4pin molex fans they will always run at 12v, the only thing you could do is mod the voltage by changing the pins around, you can set either 5v or 7v depending on how you arrange the pins.
I personally use a hardware fan controller, which i find much easier to manage fan speeds, mine has the ability to completely shut off the fans if you don't need them (downloading or idling during the night when the extra airflow isn't needed).
You could look into buying quiet optimized fans, there are quite a few out there in a wide range of shapes (not so much), sizes and price.

I was looking and maybe ill buy one for rear exhaust, as it pushes down he 100% loads temp by degree, but it means 33 instead of 37... but I will get a PWM fan for sure to the back, and maybe a fan controller, seems better then the software one ( it reads high socket temp and runs my fans loud)
Any preference for fan controller? It should be cheapish, not too fancy, but something decent

And about PSU?is Cooler Master 600W Modular A: Good PSU and B: reasonably quiet? or XFX would be a much better choice?
