- By request, a deeper dive into how 3 and 4 pin (PWM) fans work. Turns out that PWM fans are a lot smarter than I thought, and 3pin fans are a lot simpler than I thought, and neither work the way I expected!

I thunk these videos should be in a new series called 'lets talk computers'
lol "I'll leave the dust there, just to trigger some people"
This is my new favourite channel. I watch one every night these days. Helps me chill and unwind. I enjoy learning something new about pcs and his chill personality and clear explanations make for an interesting, relaxed, entertaining watch. Bravo!
I hope he gets sponsorships someday. His clear knowledge and expertise, to me, make him one of the top tech tubers there out there!
Very cool video explaining something fairly complicated that really doesn't seem like that when you look at what it does. I think you nailed it in accordance to what you want this channel to be. Thank you!
Man this is REALLY clever! Thank you so much for this video! I've sat through this and enjoyed every bit of it!
How do Graham Fans Work?
Your sleeve ends look like they’ve been caught in the fan many times 😂 great video! Very informative 👌
Really interesting content and very well delivered
a mundane fan is such a sophisticated device.
When I was a kid in the 70's TV wasn't available 24/7, not in the UK anyway, so if you got up early on the week end, I could never sleep as a kid, there wouldn't be anything to watch, except for the Open University on BBC 2, and that's what this reminds me of of.
Had not thought about hall effect sensors being used as tachos and schmitt triggers to covert their output from analogue to digital. Nice work....clarity.
Wow thanks Adam yet another great video and I have learnt allot from it. Kevin
Super interesting video, thanks for that! I came here because I was scratching my head while trying to understand how it works when people are "PWM"-controlling 3-wire fans, such as demonstrated in many Arduino-tutorial. Through your video, I understood that that is actually a brute-force method, because that kind of PWM turns the SUPPLY VOLTAGE of the Hall-sensor IC On and Off thousands of times per second! I'm amazed that it still works "somehow", especially because there's no buffer capacitor in the 3-wire fan that would remain charged during the PWM Off cycles. Would be very interesting to see what the coil voltages look like when a cheap 3-wire fan is supplied with a PWM modulated supply voltage. Also, I'm wondering whether it would make any difference to the noise of a 3-wire fan if it's controlled by PWM-modulated Vcc versus a linearly regulated, variable DC voltage. Something to investigate! Cheers!
Hi there, this is my first message here. I like the honesty, straightforwardness and non commercial attitude. So big thumbs up!. I would like to suggest an review on a case : DeepCool DeepCool MATREXX 70 ARGB 3F. In the Netherlands it's about 95 euro. I've got an MATREXX 70 ADD-RGB 3F and i like multiple things about it, especially things you don't see or hear about with reviews like the front usb and power connectors on the top of the case which are luminated. Also the big space inside the case and psu shroud which is hidden with a temperated glass, which i have never seen anywhere. You also got the DeepCool MATREXX 50 ADD-RGB 4F which is 70 euro.
Thank you for posting this
Im enjoying your videos. I think I’m becoming a fan :)
Hey man. Greetings from Brazil. Your corsair sp120 pro video helped me a lot.
That face at
For PC fan repairs, you can take out the PCB by holding the coil part in a vise and carefully twisting the casing. If you're lucky, the fan board will come right off.
