Noctua NH-U9S CPU cooler fitted in the first part of a project to make a desktop PC less noisy. The concluding part of this series is here:
A Noctua NH-U9S can be purchased on Amazon.com here: and Amazon.co.uk here: Note that these are affiliate links,…
Now swap the HDD for an SSD, and for PSU, you could just open the PSU, and install a curve bladed case fan in it.
Just make sure it's the right voltage, as some PSUs run their fans at 24V, not 12V like most case fans do.
I wish I had Mr.Bernatt as my teacher back in my school days. I would've learned a lot more stuff, really lol. I dont know, the way he speaks and explain stuff just makes me wanna learn more 😂
If only I've seen this a day earlier… silly me -_-
could you please change those cables in the pc to all black as well with the psu the current ones with the german flag are really quite offputting for me
its so small. very cute little cooler. I have the NH-D15 in my pc so next to the NH-U9S its an absolute giant. The D15 is a loud cooler, especially with dual fans. my pc sits above me on a shelf though, a good 4 or 5 foot distance from me, so noise is less noticeable. I don't like to use the noise filter that noctua provide, they limit the RPM of the fans thus stealing away some performance.
Hi, I am planning on doing something similar to my computer. Why did you choose a CPU cooler with 92mm fan? How did you know 120mm fan doesn't fit? Did you measure it? I believe I roughly measured 155mm from base of CPU to top of case? Would be tight fit. Is there much difference between 92mm and 120mm CPU cooler? Thanks for the videos! Do you plan to cover over the holes in the side to eliminate more noise?
How can you tell if that blob of heatsink compound has spread across the entire surface of the CPU.
So; anyone else just automatically click like on all computer videos to feed the Youtube algorithm and cause it to recommend more computer videos?
I got the M1 macbook air because it makes zero noise… and have my NAS and desktop running somewhere else.
The loudest part of my PC is my GPU.
Thank you for the video. I have recently fitted my Ryzen 7 5700g system with all Noctua fans and a Noctua Nh-D15S with a second fan fitted to it and it is pretty much dead silent now. Coolermaster N200 case with corsair 450 w PSU. The only downside is that under heavy system use my Samsung 970 EVO plus NVME is reaching 73C. Is this too high?
I had just added a new power supply to my computer and was wondering if I had made the right choice. Getting to the end of your video confirmed I had. Exactly the same make and model. Other than initial start up, I have had no fan noise yet. Thank you for your straightforward, well explained and informative videos.
A good way to fully load a cpu is to use the "stress" application on the command line. My AMD Ryzen 3700x 8 core cpu runs at 74.1C fully loading the system using "stress -c 16" !
I’m in awe of how lovely and clean the inside of your PC is!
16:59 That is The Problem with silencing a PC – once you silence one component, you will begin to audible notice some other. Oh, how the fun just never stops…
Another great one Chris! It is so well researched and presented. A help to us every day PC users who don't have water cooled LED monstrosities! Hope the algorithm picks up on your stuff again. Sorry I did not do my part by watching it sooner. Cheers!
The power supply on a ZX81 used to get hot.
Very good, but wouldn't it be cheaper to put the PC in a cupboard under the table/bench with some baffles on the air ducts?
Great video. Very useful. I'll be in the market for a self-build (of a PC running Ubuntu) in the next year or so. This is good to know.

Very well explained as always!
Love this program style forgive my appreciation for its retro and more utilitarian style. That why I love it. Just give us the information, less personality and joking around. I love this niche!
Noctua is very quiet and a good noisegate like the one in adobe audition can do the rest
Hey, CB! I want to compliment your excellent filming angles! Your production is on par with people who have professional film crews. Keep up the good job!

Not sure if it's still a threat but Intel CPU's had Minix running even in standby. Google Minix chips so you can read my concern.
Nice relaxing video, can't help thinking the days of PC's in metal boxes are numbered.
Would a standard fan with a voltage reducing resistor be as quiet and cheaper than a noctua?
Just curious, why not a Ryzen 3600 unless you are using the iGPU?
I wanted to make a quiet PC so I got a case from 'Quiet PC'. I'm pleased with it's acoustic quietness but dissappointed with it's radio frequency radiation. It outputs a large number of carriers in the 430 – 440 MHz band which are not present on any other PC I have.
Christopher, it's really useful that you've listed reminders of the previous upgrades in the section above. 👍🏻
Interesting that you rejected passive CPU cooling because of the additional case fans required. I've usually found that a large case fan (say, 120mm+) tends to be a lot quieter that the smaller ones simply because it doesn't need to spin as fast. That said though, you're not working on the fanciest case in the world, so your locations for case fans appear to be a bit limited.
Never a criticism of what you do of course, and you did show us plenty of alternatives too!
A nice PC without any RGB. I thought I was the only one! Lol! A nice sight!
"Lets apply the magic of film making"
Bro what!!?!? This guy is the best!
Sometimes you don't have to change the entire heatsink but just the fan if the heatsink is decent but the fan could be of a better model. Depends on what pc and heatsink is used
I bet you didn't expect it would install this close to your RAM, Idk i be keeping an eye on that or remove 1 RAM Stick.
The older Intel fan you used was 12V – 0.2A, rated with only 2.4 Watts, enough for the Pentium.
The new Intel fan you installed with the i5 have 12V – 0.6A, rated with 7.2 Watts. That produces much more airflow, but also much more noise. They are called Delta fans. There are delta fans lovers, and delta fans haters.
Your choice to Noctua looks like you are going to live happy, again!
Thanks for the video.
Always more rather than less, for the thermal paste.
me personally, I would setup a custom curve and set it to not turn the fans on at all until it starts getting warm.
I was going to say as i don't think people realise the size of some passive heatsinks, the round copper one you showed briefly is about the size of an average football,
Happy to see a new PC build video! Some of my favorite content that you do!
Thanks for this! I've got an i9-9820x that puts out a lot of heat when working hard and the Intel cooler is obnoxiously loud and high-pitched. Worse, even after fiddling with the motherboard settings it still tended to constantly rev up and down. I had thought about replacing it with something bigger and quieter but it sounded like too much effort, but after seeing this video I figured seems easy enough. I got an NH-D12L and the temps under full load dropped about 16C and it's nearly silent! The Intel fan was clearly audible from out in the hallway outside the room the computer is in even with the computer idle!
I like computer cases built just thick enough to accommodate a 5.25" drive, a 120mm at the front, and two 80mm fans at the rear, unfortunately cases like this aren't made any more.
These smaller 92mm towers fit perfectly in such cases, but the 120mm towers don't. Not a problem with the quality 92mm fans available today, but it's understandable how 120mm fans now dominate the market given how awful and droning many smaller fans were throughout the 2000s.
CPU FAN config…
That stock Intel fan could have been far, far quieter if you set an aggressively quiet fan profile. You can likely run 90degC on the CPU constantly. So I would personally have had THREE different ramps. The first is FLAT for IDLE. Whatever RPM keeps you below 60degC. Then ramp from 60degC to 80degC, then a sharper ramp to 90degC at 100% fan RPM. I use the same basic profile regardless of cooler. FLAT in idle. RAMP. Sharper RAMP. FLAT again at 100%.
Beautiful Channel. Thank you.
Thanks to your video i upgraded my pc from i3 to i7, also upgraded the graphic card, used Corsair PSU you showed in another video, a Noctua CPU cooler and case fan, the PC now is much quieter 🙂 i was thinking about buying another PC but glad i upgraded what i have, i hope it lives for another five years at least.
