Automatic fan control for my old amplifier
Вставка
- Опубліковано 8 лют 2025
- Hello guys,
I recently used my old amplifier made in 2009, but it has a noisy fan.
I decided to modify the fan speed depending on the heatsink temperature. So in this episode I will show you in detail an easy way to do this using ceramic thermal switches.
A big THANK YOU to all my patrons, especially to: Max Rice, Jon Lloyd, Max Bane and Jonathan Jones.

Great video! Your amp is working for 15-16 years and still working, in todays component manufacturers or seller the old quality is just not there, i removed a tda2030 from a old amp and it was better than the new ones
this is a very simple yet elegant solution to a problem that most of us had. Fan speed controlled automatically
Your DIY amplifier works for 15-16 years
Good job Sorin! Thank u for the post
Always love your vids, wish youtube would actually notify me when you upload
This is a simple approach you can use a ntc thermistor as a temp sensor as the resistance changes according to the temp this can control the fan using some comparator circuit(opamp) ex for some temp a fixed resistor can be used (hence the voltage drop will be same)
Hi man im your biggest fan ive watched all your videos and sometimes i watch the same video more times for no reason😂😂 and im romanian
Every time I watch this channel this is what comes to my mind...

Cool project.
Good job!
Nice. I would personally use a fan that comes with thermal control, but to each their own.
Great video!
Big like 👍
Nice mustache, too 😁
Good work brother 🎉
great job!
He's BAAAACK
Awesome..like it,my bro..👍
The diode neckclace 🤣🤣🤣
Just use a temp sensor and a npn transistor
8:30
Without adding a resistors on that circuit, you would inevitably burn those diode sooner or later.
Ok i can use it for my amplifier
اشتقنا إليك ❤🎉
ti ai lasat mustata ! good!
With a personality Electro Cutie, ah Cattie. 🐱
5:19 or you can just use an arduino
NTC
And a mosfet to control the fan just like the graphics cards fan. Cheaper and smaller
For a transistor pa amplifier
Honest question: Why didn't you use a microcontroller? An ATtiny10 or ATtiny13 would have been perfect for this job.
I need to learn a bit more programming, then I will start using microcontrollers.
Hi sorin i have a question,what are the specifications of your pc
It's an older generation PC, but it works for me. The CPU is AMD ryzen 5 1600x, 16Gb ram, SSD Samsung 970evo, 2 HDDs, Asus GTX 1060.
How can the fan be annoying late at night but not the music or the sound of the speakers ? It's just extra work . Turn the amplifire off and use headphones ant night
Actually it can be annoying. When I record the script, the microphone is near the amplifier on the same desk. I need to check what I record, so I cannot turn the amplifier on and off continuously.
Or I'm doing some audio/video editing and there are some low volume sounds I need to hear, for example relay clicks, fans turning on or off, or the hum of the electrical transformer.
I rarely use headphones, because the sound is clearer with headphones and I want to edit the videos so that they sound OK for the people that don't use headphones also.
Use pwm instead
With this transformer.... TDA never have a enough power to working with rated power...
That is correct, the amplifier boards cannot deliver the maximum 100W of power with this small transformer, but with 4ohm speakers it's still pretty loud.
This amplifier of yours doesn't look like it's from 16 years ago🧐🧐
