The Sound Of Silence

by daslolo


I gutted out the venerable fx6800e that served me so well and fit in a mATX by asrock, a 8400 and a new m.2 At first boot time was in the 7 seconds, and then I realized that the boot partition was not on the m.2 but instead it was an old SATA SSD. So I disconnect all the SSD and redo the OS install. Now bootup is 4 seconds. from ON to desktop. It's fast. I returned the 1700x because it never quite worked right and also because the cpu feels like needles in my head. The intel chip on the other hand feels smooth. And smooth it is, beside the boot time, and app startup, project build is on par with the Ryzen, compile is much faster, no stutter during games, overall it feels nimble.

About the fan configuration, I chose the u12s for the cpu because the numbers were close enough to the u14s and I realized once installed that I barely have space to the case panel, the 14s wouldn't have fitted. Kryonaut instead of the noctua gel, just because. I added a 12 and a 14 in push pull configuration and let the Asrock amazing BIOS do the magic, by setting up a response curve that shuts off the fan below 40C. It's an important detail because the u12s vibrates when the fan spins, I contacted Noctua support about that, I think the fan is faulty. The vibration is an unpleasant low frequency that carries far away. The 14 isn't mounted traditionally because I didn't want to bother with drilling holes so instead I glued some velcro to the corners. I use Velcro a lot, all the sata ssd are mounted this way, the nvme stays hot at 38C but the others stay at 20-ish, I may increase the 14 and 12 speed a little to keep the motherboard cool and, unlike the u12s, those fans don't spin until 40% power is applied.

HW-monitor doesn't recognize the motherboard unfortunately, so I do everything in the bios. The bios is very good, easy to navigate and behaves as expected... well except if you mess around with advanced boot options then you may have to restore the bios to factory.

Notice in the photo that all the fans are off, that's when under very light load. The PSU also doesnt spin. It is The Sound Of Silence

EDIT: the PSU fan started to spin. The PSU was getting heated up by the cpu radiator which rarely ever spins to push the heat backward. So I added some case flow by cranking up the front fan to 380 rpm and the rear fan to 430 rpm. 40% power is their minimum to spool up.

Part Reviews


A feel good cpu that's cheap, fast and low power. Good IO once windows installs the proper drivers.

CPU Cooler

Good passive radiator, the fan unfortunately vibrates so much at 50%+ rpm, that it generates low frequency noise which goes through everything, including these eardrums


cheap, solid, well laid out connectors, fantastic bios with great fan control. tons of IO


so fast, paired with a 8400 it boots up in 5 seconds, runs a little hotter than the sata counterparts, which requires a bit of case air flow

Video Card

faast and runs silent on low gpu load

Power Supply

handles current hiccups well, silent : fan turns off on normal load

Case Fan

mammoth fan that's excellent for case airflow, unfortunately start current is at 80% so fan curve aren't well suited for silent operation

Case Fan

a bit expensive and high power spool up at 40% but extremely silent, zero vibration and god air flow


great and cheap when it was released, very sturdy case that I am reusing, a bit cramped, I had to pull out a lot of metal to get better air flow. The case is narrow to the point that a u12s almost touches the side panel

What was the problem with the Ryzen 1700x?

daslolo submitter 4 Builds 1 point 12 months ago

slow and glitchy

Why did you pick a Z370 board for a locked CPU? Is there any other reason?

daslolo submitter 4 Builds 1 point 12 months ago

because that's all there is for gen8 chips

How are temps with the cpu cooler? I have the same cpu and am lookin at options because stock causes throttling

daslolo submitter 4 Builds 1 point 11 months ago

it depends, in the bios it says 22C but in hardware monitor it says 34C, can go up to 40C idle

This poor man looks tortured. I was inspired by the original : https://m.youtube.com/watch?v=4zLfCnGVeL4

I used to listen to the original all the time when I was a child. :)

It's fabulous stuff, I karaoke on that stuff, on occasion.

No, not me. I have a terrible singing voice.

Well, it's heavenly really. People pray to heavens I stop singing. :D

The satas don't seem to slow boot time, I think moving the boot partition to the m.2 did it, also the asrock bios seems particularly good, unless it's windows 10 that registers the satas in a non blocking way.

I added more photos of the interior, including some weird angles that show the velcro work. I didn't hot glue, the backing cures and breaks off? If I hear something rattle I'll know what it is. The velcro is glued to the rubber insulator - definitely not travel ready.

By the way, what's a more silent and better fan than the noctua? I'm having the cpu one replaced, and the 14" isn't spooling up until 80% power is applied!
