Even robotic systems occasionally need a cooling fan. When they do, the cooling circuit must be an intelligent one that makes minimal demands on power consumption and space. The circuit described here ...

A good way to reduce acoustic noise in a system is to adjust the cooling-fan speed as a function of temperature. The standard way to do that (shown in simplified form in Figure 1) includes an IC that ...

A continuously running cooling fan is a big nuisance and is not very crucial in most instruments. The 12V smart fan control presented here allows the fan to run at rates varying from once a second to ...

Well, I'm using Noctua fans which are damned well made. I was originally going with Redux fans, but I found them too noisy, so I'm going to return them in favour of NF-S12A PWM which come with a 1:2 ...

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 ...

While the number of residential fires has been significantly reduced over the last 20 years, the National Fire Protection Association reports there remain more than 45,000 fires related to electrical ...
