[Video] Quieter PC #2: Corsair RMx PSU & Case Fans

Corsair RM550x power supply and Noctua NF-F12 and NF-A9 case fans fitted in the final part of a series in which I make a desktop PC very quiet indeed!

The first part of this series, in which I fitted a Noctua NH-U9S CPU cooler, is here:

The Corsair RMx PSU is on Amazon.co.uk here:…

  1. Impressive improvement in extending the life of your i5. I, myself, favour Cryorig's silent series fans. I find they're adequately quiet in one of my rigs.

  2. My traumatized hearing, finds Noctua's fans, of standard thickness, to be the the most pleasant that they've heard, from the fan's PWM min. to their full rated speed. Yes, when displacing large quantities of heat, Noctua fans also have to go to full speed. But, my ears don't mind! I've paid about the same price for 94, 120 and a bit more for the140mm fans. I however, could not rationalize their higher price over other fans, so as to call them expensive. [Flawless diamonds are expensive, compared to diamonds with a subtle undesirable characteristic.] There are other brands of fans, many of which are highly touted by the branded seller. But your choice was from Noctua's line of premium fans! 'Nough said!

    I also use a Noctua NH-U9S to cool in my mini-tower, a stock spec Intel i9-12900K, but with a PL1-165W, PL2-175W, Tjunction-94Β°C.

  3. Regarding expensive: a night at the cinema will set you back (depending on country) 15 USD for the ticket, 15 USD for pop corn, drinks, snacks, and 3-5 for travel. You are entertained for 2 hours and will then forget the plot of the movie a week after (unless it is an exceptionally good one). The same 35 USD gets you almost two Noctua which will provide you joy every day you use the PC πŸ™‚

  4. I didn't think I'd enjoy these as much as I did. This has been an eyeopener and really rather fun to watch. Getting into the works is so much. I always found the internals the most frustrating part an you made it a joy. Thanks!

  5. My next PC will be a great deal quieter than my current PC even then that is really low on my SPL monitor at 36-37dB idle. Another great and enjoyable vid. πŸ‘

  6. Have you been watching Matt at DIY Perks, because this is right up his alley. He hates fan and really any noise from computers. I'd like to try building one of those WeeCee's, though that's just for running old DOS and Win98 games, would still be fun.

  7. Unfortunately, when you demonstrated how quiet the new fans were, I couldn't hear them over the noise from my own D-Link ShareCenter!
    Must get round to home-building a better NAS sometime.

  8. haha, I can't hear the recording of fan noise made by your computer over the fan noise being made by mine. The Noctua fans are a great choice (I'm using a laptop – older MacBook running Linux – so don't have the option)

  9. What a relief (and joy) to finally see a NORMAL PC on YouTube.. All those "rocket ships to the moon" builds are so Zen'-depleted :O) Props to Mr. Scissors, s/he's sharp!

  10. Your upgrade and tests make sense as Britain is raising its energy prices. Having new fans and energy-efficient PSUs is indeed quite crucial for reducing noise pollution, excessive energy consumption as well as cooler temperatures to keep the motherboard and hard drives safe as they don't like heat that would brick the HDDs and maybe melt the soldering or worse pop several of those capacitors etc

  11. Hi Christopher; thanks for great video; what about power efficient computer for windows while practically usable for basic office work to reduce carbon footprint ? it would be great for you to do video(s) on such topic …

  12. Great series! I was coincidentally also on a quest for a quiet but decently powerful computer a few months ago and settled on a second hand Mac Mini from 2012. Not only is it small, it also is whisper quiet under normal use and only barely audible under load.
    Definitely another use case than your build, but still a valid option to consider!

  13. Yeah, I love these. I really like how practical your approach is. Most people building PCs on YouTube are going for these crazy unobtainable high-end machines. It can be cool, but I really appreciate how you have a realistic purpose-built mentality. You let your experience carry the content instead of relying on fancy hardware.

  14. Please Make a tutorial on Raspberry pi 4 based PLEX SERVER, with nas service enabled so that every time we copy a movie it can be done through device available on lan and no need to unplug the SSD from RPie4.

  15. 07:46 I find semi-fanless PSUs to have an inherent flow: if the fan fails to spin properly, the whole unit can can be damaged. A complete fanless PSU takes care of that, unlikely but possibly fatal, occurance

  16. The episodes on this channel kinda reminds me of British educational programs they use to air in the1970-80s. Very informative, straight to the point and with simple sound effects between the chapters. I like it πŸ™‚

  17. Does that bag of bits add up to anywhere close to the cost of a baseline M1 Mac Mini, which most of the time is completely silent (and could no doubt be throttled to never use the fan, as per my MacBook Air that doesn't have one).

  18. When I disconect my PC from the wall socket it looses its configs so when i turn it on it makes a TON of noise, sounds like I'm trying to launch a rocket. 10 years from now I'll buy a new 3V coin battery.

  19. Those silicon mounts are a great addition, they reduce the case resonance quite a bit on a computer that runs hot but at those low low fan speeds that shouldn't make much of a difference.

  20. I would have picked a 80 Plus Platinum with around ~90% efficiency and fanless πŸ™‚ There are some that do not even have and do not need fans at all. Because of their very high efficiency. Means normal case airflow is more than enough for these. If you want to go all silent and full premium that is πŸ™‚ There even exist PC cases with huge passive radiators on the outside area side windows. Which makes them look a bit like a room heater, with this wavy shape of heat fins, to increase its surface area πŸ™‚ Those only get somewhat warm, while pulling out all the heat from your processor. This way, even your CPU can go fully passive. Even under full load πŸ™‚ And the heatpipe system is fully modular. So it fits to any common standard board πŸ™‚ But such cases are rare and pricy πŸ˜€ It would give you absolute silence on a powerful system though πŸ™‚ But your build is very silent already and I like the simple looking case! Very nice to look into, without all those sprayed colors of black inside, that makes it so hard to see things inside of modern cases nowadays, at low light conditions. I prefer this bright, unpainted, metal look, that your case has, to be honest. It makes the insides look brighter and easier to see. Because it doesn't eat up light πŸ™‚ Sadly those sturdy retro cases of the past with cream colors and simple designs are not produced any longer πŸ™ Nowadays, mesh and black spray color and glass sidewindows etc. is all made to be eyecandy. But for people like me, who do not want to be distracted from the PC but rather prefer simple and unobtrusive designs, that even do have slots for disc drives (5,25 bays), it's a hard time nowadays πŸ™ Atleast my case still has two disc bays. So I can put a DVD burner into one and a fan control with temp control display integrated into the other bay πŸ™‚ Something that doesnt fit into those "modern" cases without disc drive bays… Or lets talk about front connectors for professional soundcards, to plug into music instruments. Not possible without front bays in modern "bling bling eyecandy" cases… It's sad how much they focus on eyecandy nowadays, but how little on practical use πŸ™
