As one does I was thinking about my bedroom fan/noise usage in the middle of the night.

Call it 30 years, 9 hours/night. The current fan is about 55/w, 181kWh/year.

So 5430kWh for all that time.

Which is about the normal > 1 year < output of a modern 5,000 kWh solar panel, roughly 25 - 35 square meters of roof space.

I've got a process than runs every hour; it does a local backup snapshot, and checks the snapshots for validity.

It goes full-hog on my storage, and calculates some checksums/hashes/etc., so it's also pegging the CPU. It does this for a pretty short time, but it's long enough to spin up my fans. I want it to stay quiet.

I'm running it with `nice -n 19 ionice -c 3`; is there anything else I can do to slow it down?

I recently got a 3D printer, and I just figured out why I get a visceral reaction at some points during the prints.

It’s the fan ramping up that brings me back to the bad old days of mid 2000s windows laptops that burned your legs and had those loud screaming fans!

While playing with Nextcloud I saw that the raspberry pi was overheating so I played with a fan for people to cool the device. It worked well, except that when you’re holding a fan you’re stuck holding a fan. I looked at various Raspberry pi cases and decided to get a Joy-IT case with an integrated fan.

The case is simple. It consists of a base plate, a middle block, and a top plate. You put the pi, with the card inside. You then plug the fan to some of the GPIO pins and the fan starts to spin and cool the Raspberry pi beneath. The Raspberry pi went from 50-70°c to 38°c so it works, but it’s noisy. It seems paradoxical that something as small as a Raspberry Pi could end up with such a noisy fan. It’s as noisy as an old laptop or an old external hard drive.

This does not mean that I don’t like the case. I do. I think it’s great that it is so simple. You don’t need screws. You just put the card into the Pi’s card slot, put the pi on the base plate, put the middle sandwich part over the USB and ethernet adaptor, you then plug in the fan to the GPIO pins, and put the top on.

In my case I found that the fan seemed to be blocked so I improvised a solution to keep the fan from hitting the Pi and now it’s happilly spinning and cooling the Raspberry Pi. For 11-12 CHF you don’t expect it to be as silent as newer mac book pro.

As I write this post I’m playing with the time tracker app in Nextcloud. With the app you can provide project names, and then you can specify the task that you’re currently doing. I created an IT project, and a blogging project. Now I’m tracking the daily blog post time spent, and when the post is finished I can stop the timer, and see how I have spent the morning.

And Finally

I think the fan on this case is so noisy that it would fit right into an air conditioned server room, but it’s too noisy for a living room or bedroom. I need to place it where it won’t be so disruptive.

Asus ROG Ally overheating can kill your microSD card reader (and cards), so Asus plans to crank up the fan speeds a bit, which could make the handheld noisier, but safter to use. Affected users can request repairs. https://www.tomshardware.com/news/asus-admits-rog-ally-microsd-card-reader-may-malfunction
