The TC648B is a PWM fan speed controller with auto-shutdown, fan restart, and FanSense™ technology for fault detection. The device features over-temperature indication, efficient PWM drive, and it ...

Withclosed loop speed control, the fan controller ensures that the fan isrunning at the desired speed by measuring the actual speed and adjustingthe duty cycle accordingly. Here the host specifies the ...

For those of you cooling enthusiasts, you probably know Noctua by now and they make great cooling products, so when they decided to introduce their new NF-F12 PWM fan, we were more than happy take a ...

This post is a quick sequel of my previous article jam-packed with my personal experiences and observations while I was fiddling with standard 4-wire PC cooling fans. Today I will be talking about the ...

When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...

In my previous article, I described the four most common methods for motor and pump control: input voltage, input voltage pulse-width modulation (PWM), external PWM, and 0–5V DC analog speed input.
