Near Silent PC Build

Jonathan Cave · Mar 16, 2017

Hello all,

I'm looking to re-home my PC components and into a near silent PC, to be frank i've only ever used Air cooling and i have no desire to learn and build a custom loop (unless this is the only way) i've never tried or seen IRL any AIO coolers.

I want the PC to be as silent as possible but to maintain/improve current temps under load, CPU/GPU ~64 degrees.

What are my options?

spec:

4770k 4.4GHz 1.3v
EVO 212
16GB DDR3
MSI G45 Z87
Gigabyte Gaming 1070 (1080 ti on order)
2 x SSD/
HDD
XFX 850w Bronze PSU.
Define R4 case

A good resource is www.silentpcreview.com
Quiet essentially means slow moving fans.

Make that GTX1080ti one of those that are not overclocked and does not need superior cooling.

Your cooler now uses a 120mm fan, which is OK.
Better would be something like a noctua NH-U14s with a slow moving fan.

Use a ssd, not a hard drive.

A good quiet case can muffle some sounds. Look at spcr for suggestions on quiet cases.

Your psu is good, it can loaf and will not need the fan for cooling.

Thanks for supplying the link, i'll take a look.

I've gone with the Gigabyte Gaming 1080 Ti, theres no info on it yet, but has the 0 fan movement unless needed.

My PSU seems to be the loudest out of all my cpu/gpu/casefans

Here's a video of my system under full gaming load the coil whine on the GPU is bad but that card will be sold once the 1080 ti arrives. I wonder why the fan on the PSU is spinning so much.

I do not see your link.
---no matter---
I am surprised.
XFX is supposed to be one of the better units; made by Seasonic.
I do not see them sold any more, perhaps it has aged.

I suggest for a quiet psu, you look into one of the gold/platinum rated units.

I have never heard the fan on the Seasonic X-750 gold rated unit I use.
The documentation warns you to not be alarmed if the fan does not turn on.

Another thing you might do is overprovision the psu so that it loafs.
In fact it will be most efficient in the middle third of its range.
It will only consume the wattage required, regardless of the max capability.

The video/link is definitley there mate. Yes i bought it because of the seasonic components. The fan definitley spins up as you can see/hear on the video. Perhaps the case is getting too hot and it needs to spin up?

its this PSU: http://xfxforce.com/en-us/products/pro-series/pro-series-850w-psu-core-edition-p1-850s-nlb9

does the PSU pull air in or blow air out ?

I has some content blocked.

A psu will always exhaust air out the back of the case.
Dangle a tissue near any fan to see which way the airflow is going.

I see two top fans that are really unnecessary.
Your case will stay cleaner if all your intake is from the front two fans and if they are filtered.

Adding top fans as exhaust will draw in unfiltered air nfrom nearby openings.
Using top fans as intakes will tend to disrupt the natural case airflow.
It will not impact your psu noise, but see what happens if you disconnect the top fans.

As to the psu noise, I can only guess that there is something wrong with the unit.
It has a 5 year warranty. You might try to rma the unit and replace it with a gold/platinum rated psu.
