First AMD build with 7700, ̶R̶T̶X̶ ̶3̶0̶7̶0̶ RX 7800 XT+ Ceramic coating of Fractal Torrent Compact

[madseason]

I wanted to build the quietest air-cooled PC at reasonable price with DDR5 for snappy response - therefore AMD this time.

 

There is not much to say except for the "butcher mods"

1. RTX got new thermal pads from Thermal Grizzly - minus pad 8 and Noctua thermal paste. I had to put a fan next to it, because it is too passive now and want to give it some quiet airflow while still on the bench 

2. Ryzen Wraith stock fan assembly replaced with Noctua fan, and 7700 itself is undervolted to negative 50, just sipping power, with minimal heat, it is running 1200 rpm most of the time while doing office work.

3. RAM is set to 6000 - there may be some room for improvement, but I have no idea how to do it right.

 

Here is a bench - it works great at this config - 100% stable:

Plans for near future to make it even more quiet and complete:

Noctua NH-U12A chromax.black - as CPU fan is the loudest thing right now.

Fractal Torrent Compact - to have good airflow at low fan RPM.

Why the low profile downdraft cpu fan?

Think fuma 2/ak620/phantom spirit 120 would be a better choice than the u12a simply cause price and they have equivalent cooling performance

Agreed

To be the quietest possible cooler needs to have the biggest possible heatsink and a couple fans at low speed

A very small heatsink needs the fan to go high in speed thus becoming noisy

I have Fuma 2 in my intel build, I have replaced fans with NF-A12 on it to make it even better, but with money there comes quality and great quality fans, so I not not need to upgrade them in future, because I know I will

You forgot one thing - it is not Intel

My Livingroom 12600k can take 250W under load, and in this case Fuma2 is fine, 7700 takes 88W max under full load, all cores over 5GHz.

Noctua NH-U12A for performance, quality and compact look that I am after.

Sure you don't need a super beefy cooler to have good temps, but a bigger heatsink will always help 

NH-U12A is okay indeed

Get a ak400,.... all that stuff its going to be quiter than rhe u12a because its bigger.

 

No point in getting a worse cooler juat because its noctua they arent magic.

Besides arctic p12 already match noctua, let alone the new p12 max

That and for example the fuma 2 if you noise normalize em to 35 db(the sycthe fans dont even go that loud) the performance difference between stock and spending the coolers price on fans is about 1c. So yeah not worth in the slightest

 

Noctua got its name for being one of the few quiet great performing options and being amongst the first and best in their more niche segments that later became widespread.

 

They are still goos but competition caught up and you can have the same performance noise and temps in stuff half the price.

In the meantime, someone tried to bend my new keychron in transit from China, fortunately - unsuccessful attempt

props to the packaging for keeping the keyboard intact after that abuse

It is the metal frame of the keyboard, not the packaging that saved it

It is coming together - proper CPU cooler in place 

 

[madseason]

And it's done. Looks much better than on pictures

Any idea why the pictures are gone missing from previous posts?

I knew that there is a lot of plastic in Fractal Torrent and what are the consequences of it, so I decided to do what I know will work best - ceramic coat it.

The amount of factory dirt is crazy, just the top cover took lots of alcohol and cotton pads to clean it. 

Results - judge it yourself

 

 

Cleaning done with alcohol - lots of gunk.

 

 

 

First ceramic coat

 

2 coats of ceramic vs filthy plastic on the right.

 

All plastics coated twice for deep black satin finish

Latest update to make this a quiet PC, 3x stock GPU fans went on retirement, replaced by 2x 90mm Noctua.

 

3'C less in furmark with much less noise. Now I can say it is done

As I have fully switched to linux as my daily - it is about time to throw out garbage from my PC
Out with RTX 3070 in with RX 7800 XT. Now I can play Cities Skylines 2 with much more than 3FPS in traffic jam view
