The Raspberry Pi 4 needs a fan, here's why and how you can add one

The Raspberry Pi Foundation's Pi 4 announcement blog post touted the Pi 4 as providing "PC-like level of performance for most users". The Foundation even offers a Raspberry Pi 4 Desktop Kit.

The desktop kit includes the official Raspberry Pi 4 case, which is an enclosed plastic box with nothing in the way of ventilation.

I have been using Pis for various projects since their introduction in 2012, and for many models, including the tiny Pi Zero and various A+ revisions, you didn't even need a fan or heatsink to avoid CPU throttling. And thermal images or point measurements using an IR thermometer usually showed the SoC putting out the most heat. As long as there was at least a little space for natural convection (that is, with no fan), you could do almost anything with a Pi and not have to worry about heat.

Review: Truffol Autograph Fusion iPhone 6 case

Jeff's Rating: 5/5

tl;dr: The first time I've put a case on my iPhone—and kept it on after a week!

I have always disliked iPhone cases. I've owned every iPhone since the beginning, and have never used a case; instead of a case, I kept the phone in a holster case on my left hip.

Every once in a while, I tried a new case, but returned it to the store within a day or two. There were always too many tradeoffs in terms of usability with docks and different headphone and dock plugs, and most cases made the phone harder to hold and use.
