I'm actually looking on eBay for case fans. I found a lot of them for sale and they include some deltas. These fans draw 1.6 amps at 12 volts, but I do think that they would still be pretty loud. I'm going to prank my father by putting one in his office PC😂
Wow. According to my dB meter App, jet planes are 120dB during take off & that's damaging to the ear after about 30 seconds. This fan's dangerous! edit... Ok, i've realised it's not in dB heh. Good for comparison anyway, as you say.
now i bought two of the same, may i ask how did you get the fan plugged in that you are able to control their speed through the software? I wanted to attach them to the heatsink of my processor so that they are controlled by the board CPU temperatures, it is clear to me that they must be powered from molex but when I swapped the pins in the connectors so that it goes from molex 12v power supply and from the board negative and yellow one to speed control so the fan did not start, I probably only have to plug the blue and yellow into the board, am I right?
I control the speed through hardware, with a Noctua NA-FC1. I have a split cable for this, with the power pins going straight to the PSU via molex, and the other two going to the controller. I think you are right with your assumption. Also, the fan on this video has inverted speed control - 0% PWM is full speed, while 100% PWM is stopped. I'm not sure if they're all like this.
The Pwn signal are inverted on these TFC and PFC series so even if you swap the Yellow(PWM) wire and Blue (Tac) to standard PC 4 pin the fan would work in opposite, CPU heating up will cause this fan to slow down and a cool state will be 100% rpm annoying none the less. I bought a 3 dollar 8 channel Pwm Miner fan controller with a potentiometer which also works in opposite but does the Job.
I have tow of this，i like it's blade so i bought it. But at daily 800-1500rpm, the blade wind cutting sound is significantly greater than the airflow sound，that's pretty noticeable， even when compared to cheap consumer grade products.
Other than that, there is no appreciable motor and bearing noise. I bought it from an agent, and the price is about 9USD（66RMB） per unit，i think for some people who don't really care about a little bit of noise it's a good value for money
i bought a tfc1212de too im trying to get it to work on my pc lol cause my motherboard cant supply the needed power so i am trying to make it get power off the power supply
Yeah it can be annoying to power. I have a split extension cable for this - +12v and neutral go straight to the PSU via a molex connector, while the PWM and Tach go to my Noctua NA-FC1, which connects to my motherboard.
@@Kadencabs Unless you want to do my split cable setup, your best bet is to use a Noctua NA-FC1. It can supply 3A, which is probably enough to run this fan at almost full speed. The rating on the sticker is generally the peak current draw if the rotor is stalled or something.
the noise from these fans arent the blade design or the ball bearings ,they have a powerfull and strong motor ,thats why they are noisy as fuck ,also the reason why they can operate at massive speeds while sustaining no strain or damage ,they can last 5 years at full speed... these arent build for "comfy" ears xDDDD
I think the motor uses excessive power at low speeds and generally has excessive torque though. More modern fans that have similar performance will operate a lot quieter at lower speeds. The reduced torque is noticeable though in that they will generally take longer to spin up
That unusual blade-to-hub junction looks particularly good at noise generation. That's on top of the crazy bearing noise.
I think most of the noise (especially at lower speeds) comes from the commutation, but those things you mentioned certainly all add up.
As a rule of thumb Sanyo Denki fans will always be quieter than a Delta for the same amount of airflow...but then some Delta fans have impressed me.
At 900 RPM you can see keyboard's backlight being multiplexed row by row.
Would you mind to redo this with dB as parameter instead?
imagine putting your finger there at 4K rpm
I like this noise!
chad KDE enjoyer

Ah i remember this chanel.

It's not a dB meter, it's nowhere near that loud. It's still pretty loud though
CPU: Wow bro okay okay chill!😮

Hi, can you do the same test with rpm and loudness stats for qfr1212ghe?

Please tell me you wore ear protection
Love This fan ❤ 💕 💖 💗 💓 😍
Fan sound siren
Awwe I love your baby so much 😘
Can it go to 300 rotations per minute and be silent?
i bought a tfc1212de too im trying to get it to work on my pc lol

@@ydihtty yea I’m gonna use a moles cable too
@@ydihtty do you know how i can control the speed of it somehow?

@@ydihtty interesting il look into it
This fan is out of lube in the bearings.
Bro I got that one and I’ll try to make it work on my series X 💀
i need this fan for my watercooling system uwu
Is that your suit in your profile pic? Either way, nice suit uwu

Same with drones brushless motors, mini 4 pro I can barely hear the propellers spinning, but the motor humming is way more audible
Awful. It sounds like a cheap ball-bearing fan.
It is a pretty old design, not really optimised for acoustics at all.
It's a fan that gets the job done, with no regards to noise since normally it will be in server room anyways
