Thanks for the video. If I may point out something: You have two different fans in this video. You installed NF-F12 fans but the case you showed and the last one you installed is the NF-S12A. These fans are very different as you can see in the fan blade design. The NF-F12 fans are built for static pressure where there is a lot of resistance, i.e. using on water cooler radiators. The NF-S12A is built for high air flow. Based on advertised specs, there is about a 8 CFM different between those two fans.
The 1st reading you took from a couple meters away with the case fully assembled. 2nd reading the phone was in the case. There was a lot more than a 4db reduction.
4dB is a nice difference ! Keep in mind dB are logarithmic ! 4dB is 2.5x less noisy than before, seems like that it's really worth the extra ! ;) Rule of thumb : 3dB is 2x louder and 10dB is 10x louder.
Thanks for commenting! Thanks for the info of dB being logarithmic. I started to dive into this a bit more after your comment! Thanks for enlightening me!
You are right. I did. I did an updated video with my corrections ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-p-yJKs2SvTU.html. Appreciate the feedback
Hi there. Thanks for watching. You are right. I actually did an updated video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-p-yJKs2SvTU.html where i corrected my mistakes. Thanks for watching.
If you have enough positive pressure in the case from the fans, you don't need an exhaust fan per se. This is due to the fact fluids (water/air) follow the path of least resistance without assistance. If both the front and top fans are used as intake fans, then there is enough positive pressure built up that will cause the air to exhaust out of the rear of the case from any opening there is. A well designed case built for airflow, will not require an exhaust fan. Where as any ole case that isnt designed for airflow in mind, will require an exhaust fan as you will have the situation of stagnant air which will cause temperatures to build up.
Noctua do black versions of 120mm and 140mm fans-the "Chromax" edition and the Industrial versions, a bit expensive, but you are paying for the quality - you can also get an all black "Chromax" edition CPU cooler
Thanks for the input. I agree, the black ones look way nicer! I may do that for a future build. For now, my desktop is hidden under my desk, so it doesn't bother me so much. However, if it was in plain view, i would switch them out for the black out versions for sure.
You are totally right ! I am going to do an update video on the issues with positive pressure. I am going to turn off one of the front fans. Thanks for watching!
@@AF-rm4dr It’s debatable and goes by a case by case basis. Nothing is wrong with positive pressure but if you have all positive pressure with no exhaust the positive pressure will do nothing but blow hot air around
Hi there. Great suggestion. I ended up replacing my AMD wraith cooler with the Noctua NH-u12S Cooler and the sound made such a big difference. Unfortunately, i wasn't being careful and I erased all of my footage on the installation tutorial. Thanks for watching!
@King Everard Conquerors Blade Gaming Yeah, that's your CPU cooler. Both AMD and Intel have painfully loud stock coolers, you should get a 3rd party one. Depends how comfortable you are with replacing it (and finding the right one, rated for your CPU wattage)
@King Everard Conquerors Blade Gaming Seems good, which CPU do you have? Also, do your other fans show multiple colours at once? Not just a solid colour that changes? If so, the lights will work (it's ARGB)
@King Everard Conquerors Blade Gaming Ah if it's a quad-core AMD this cooler will be good. I'm not sure if the lights will work, unless your board has the connector for it. If you hit Start and type "System info", it'll show you a list of your PC parts. "System Model" is your motherboard name
If noise is all you were trying to eliminate, then just go into the motherboard bios and set up your fan profiles for each fan port on that board. Noctua are always going to be a better choice. They usually last over 3 times longer then any normal fan. Just make sure you are getting the ones with PWN so you can control the speed better. Turn those fans down to around 1200 rpm instead of 2000 and it makes a huge difference in dBs levels. Each noctua fan also comes with a low rpm adapter that looks like an extension cable. It drops the rpm down to 900 (to low in my opinion).
thanks man, you sved me money. i was gonna buy them, because i have a set of 4 cooler masters fan that cost me 15 usd, they are silent enough but i thought that with the noctua ones i was gonna have a HUGE difference but apparently not, plus the fact they are very ugly and difficult to match with a case.
Thanks for watching. Yeah, honestly, for the premium price you pay for them, I don't think it was really worth the dB decrease. Glad I was able to save you some money. I agree they aren't pretty to look at.
