They are real loud. I should also note that I bought these (https://smile.amazon.com/dp/B07DB7DLMM/ref=cm_sw_r_cp_apa_fabc_pGk3FbMKGSAK8?_encoding=UTF8&psc=1) and it doesn't seem as though they respond to software speed reduction.
That said, that benchy from the photo had very little stringing without tuning the profile much and the underside of the roof looks almost better than the first layer!
Sadly no because I could mot find them, I tried not to buy the cheapest out there but reading the specs of fans turned out mote challenging than I expected, every chart seems to measure different metrics.
I got these from amazon:

Are they wrong?

These are what I’ve been using for parts cooling. I also use their dual ball bearing fans for hot end and mainboard cooling. Dual ball bearing carries a 24 hour duty rating. They don’t need a rest. My mainboard fan is also directly wired to the PSU so I can print PETG with no parts cooling and not have to worry about cooking my cpu. The color changing fans are cool, kinda gimmicky for me though. I had three fail in quick succession so I won’t go back for a while. The one I’ve currently got on my hot end has been there for about 10 months. Same for the cpu cooling.
If it doesn't work its no problem could be a chance for you to get some of these:
If your gonna get a new one might as well go all the way
This guy knows what he's doing. He's been helping me almost daily since I bought my printer about 2 weeks ago.
I've pretty much done all of this with a few exceptions:
>Mainboard
I went with the BTT SKR Mini E3 because it was cheaper. I used this guide to compile my firmware. First issue was hitting upload would not sent to the sd card which was inserted into the usb adapter that came with my printer. You have to manually copy the firmware.bin file from Marlin/.pio/build/STM32F103RC_btt_512K/. Second issue I ran into was my screen would stay blank when trying to update the firmware. Strange because the file extension changed from .bin to .cur which means it should have updated. Turns out the sd card that came with my Mini E3 was bad so I used the one that came with the Ender 3 Pro and it worked fine. Third issue I had was that the drivers were still loud even though I enabled StealthChop in the firmware. Turns out there is a jumper in the wrong position. I wasn't the only one with this issue. All drivers are silent now and the loudest thing is now my hotend fan, which isn't that much louder than my 4u rackmount server with 3X 120mm fans in the front and 2x 80mm fans in the rear.
>Cooling
I went with the same listed hotend and PSU fan but went with the 20dB version of the board enclosure fan. At the time I bought the fan no one had many 24V 5215 blower fans in stock. In my search for a 5015/5215 blower fan I came across this 4-pack for $20 on Amazon however the reviews are all over the place and I wanted something with ball bearings instead of sleeve bearings. I went with a Delta BFB0524HH. All of the fans with the exception of the PSU fan (as Noctuas are more consumer retail products) were purchased from DigiKey as Mouser didn't have much stock. I run the part cooling fan at 50% for PLA, as was suggested by OP.
>Vibration dampening feet
I haven't done this one yet as I'm not quite sure if this will silence anything after having silent motor drivers. I already bought the squash balls though so it's only a matter of time.
>How to install new fans
I thought the JST connectors looked a little bulky. Thought about DuPont connectors but wanted something that would click or lock together. Decided on these JST-SYP connectors (more commonly known as JST-RCY which are used for batteries on RC cars and drones). I'm not positive these are that much less bulky than the JSTs. I went for this cheaper crimping tool made by IWISS instead of Engineer for less than half the price.
Just these cheap Winsinn dual bearing ones from Amazon.
This is a direct drive setup, so being heavier and slower might reduce that vibration for me.
These are the fans I'm using: https://www.amazon.com/gp/product/B07DB7DLMM/ https://www.amazon.com/gp/product/B07DB5H6K1/ Along with the fan ducts and stuff talked about here: https://www.youtube.com/watch?v=dbS9MA4UkZA&t=1633s
Gotcha! On my ender 3 (same hot end) I use:
a Red Squirrel Hot end:

and a Winsinn 5015 Blower fan:
https://www.amazon.com/gp/product/B07DB7DLMM/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1
Is this the fan you’re talking about?
I bought the Briss Moto stl but am nervous to figure out PETG to print it. Would the 5015 fan be better than using this with some noctua (or similar) fans? I don’t know enough about cooling to decide one way or the other, I’ve just been kinda half-blindly following the advice I find on here and YouTube.
Is there a much more basic system that supports the following?
You get 4 for 23€. They a not quiet but do their job.

I had a hard time finding good fans. So much so, that I never did find any. I just ordered some cheapies on Amazon. I went with the cheaper bearings because they’re quieter, but their life is about 50% of the better bearing. I went with a 4020 vs a 4010 so I could push more air at lower RPM.
I don’t expect the fans to be any quieter, but maybe I won’t have to run them as high, essentially making them quieter.

These are the ones 3DPrintSOS recommended as the dual ball bearing is rated for longer run times
Does it need to be 4010 blower? 5015 is popular
Im using these Winsinn 24v blowers. They work great! Albeit a little noisy in a dual setup like this. :)
I keep pushing this write-up, but it really is excellent. It should give you some additional details about which 5015s, connecting them, etc. I based most of my machine's cooling setup on this, so I can vouch for it.
Edit: Upon revising the guide, it appears 5015s aren't examined in-depth, but there are example shrouds listed. The wiring is similar throughout, so it may still be useful.
Though not perfect, the 5015s I had laying around are these. They're quiet enough to not bother me and pump out quite a bit of air vs stock. Again, you can get much better blowers, but these are cheap and effective.
These are the files you'll need for the Bullseye/Petsfang. There's also a chart in the download that should help you determine what you need for any accessories you're adding (ABL)/checking my math. Just locate the hotend setup you have at the top and look at that column for what you need.
Bullseye: BULLSEYE_BASE_CREALITY_9.27 & BULLSEYE_DUCT_9.27
Petsfang: CR10_STOCK_MANUAL_CASE_V11.3 & CR10TEVO_5015_DUCT_V7.5
​
I cut the existing wires for the fans and wired in a connector for easy replacement down the line. Just make sure you get the 24V and not the 12V.
