This PWM Controller circuit is ideal for controlling small motors with 2A maximum current consumption. For higher currents you need additional cooling for T2 and increase C2 value. This pwm motor ...

A few weeks ago, I saw a reader’s question about how to run PS3 cooling fans using an external electronics circuit. At the time I was busy with some other projects. The other day, I decided to put my ...

Optimised performance, efficiency, and reliability in high-voltage power supplies need to be combined with reduced BOM count and cost, as well as lower design efforts. The FF CoolSET solution combines ...

This is a very cool electronic project to control dc loads using a very cheap and reliable design. This video also explains ...

Since the early 1990s, the power requirements for VCC core voltages for leading-edge processors and ASICs have become increasingly demanding, with chip voltage decreasing and current increasing. Early ...

I realize I am resurrecting a rather old thread, but has there been any updates on this? I too have PWM fans I bought for a 3 year old motherboard that I thought had PWM fan headers. I can't seem to ...

A cooling system can sometimes be a buzzkill. You drop your badass engine into your badass hot rod, and then you remember you've got to keep it cool. As an afterthought, you order a big aluminum ...

[hedgehoginventions] wrote in to share a little modification he made to his video card in order to keep it from overheating during strenuous 3D tasks. Having swapped out the stock cooler on his Nvidia ...

Maxim has introduced a bi-directional current sense amplifier with pulse-width modulation (PWM) edge rejection. Called MAX40056 it is intended to reduce vibration in motor drives. The claim is that it ...
