Building a Quiet PC

So I eventually got fed up listening to the racket my old PC made and decided to build a quieter one.

The key components as far as keeping the noise down are:

Soundproofed case
Quiet power unit
Quiet CPU fan

The CPU fan needs a reasonably up to date motherboard as it's a bit of a beast and weighs about a kilo so a newer MB is needed for the mounting system.

The difference between my old PC and the new, quiet one, is like comparing the noise an electric car makes against a truck.

 

thanks for sharing

 

What about a decent water cooled system? You won't hear a peek.

My brother recently built a new system because he required more power for gaming, and programming and what not and it works perfectly. You have to get real close to even hear a tiny sound.

 

I looked at those but I wasn't keen on water being in my computer. Too afraid of a disaster.

 

i have a heatsink almost like that.the fan burned out,but still keeps my core 2 quad cool.

 

Unless you're an idiot, disaster is very rare with water cooled systems =] Only disadvantage is that it can be quite costly compared to a standard fan.

 

Can't you get a replacement fan?

It wasn't just the water-in-the-computer part that concerned me about water-cooled systems - it was the requirement to remember to top up the fluid on some of the systems I looked at that troubled me. That, and it was 3x the price, of course.

Edit: here's my PC during the build (still a few components to go in)

 

I'm running a mac, and when Mac had a watercooled dual G5 system I bought one, it's whisper quiet. It lasted me 3 years without having to top up any coolant. Just go with someone who's experienced with rigging water cooling systems up and you should be good. I just wish they had water cooled systems for the newer macs. My current Octo core is pretty quiet though..

 

if i don't have a heat issue,there would be no point.
i would have to take out the mobo...not a fun project.

 

3 years, huh? That's pretty interesting to know. I thought I'd be checking the water levels every few weeks then getting paranoid about it and doing it all the time, then not bothering until smoke started coming out.

Octo core? As in, 8x processor? I thought hex was the pinnacle of processors at the moment and I got a shock when I checked processors and found there was such a thing as a hex core lol.

Ah, fair point. That is a big job as far as computers go.

 

I think using that water system in pc is very dangerous heat sink enough for heat control.

 

I also don't use water cooling and my PC has almost no noise. The loudest part is the HDD

Used:
Semi passive PSU: NorthQ and Enermax has some models
Passive VGA
Controlled CPU Fan
Low noise HDD with vibration damper

It is a 4core workstation and not a hard core gamer PC

 

All I did was buying a great cooler and now my PC doesn't make any noise anymore

 

if you want a buid quiet PC, just try airflow fan who have low CFM
