I've been building water cooling PCs for some years and lately focusing mostly on SFF builds. Anyway, long story short, working with mini ITX motherboards created a problem.. no TEMP headers on most of them. Even full ATX ones don't have any anymore unless you go into the very premium sector.. and that comes with other headaches.

So I wanted to solve this problem once and for all and decided to build a small controller that supports water temperature readings out of the box and not being OS / BIOS dependent at all.

It's an open source/open hardware solution available for download on [GitHub](https://github.com/kennycoder/waku-ctl). Parts are mostly off the shelf components, available from mouser, digikey, and similar shops.

Happy to answer any questions and I hope this is useful to someone!
