    About a year ago I got a Tesla K80 off eBay for about $200. It's basically 2 Tesla K20Xes in one card, so it's pretty powerful, but the downside is that it's a datacenter GPU - it doesn't have any cooling.

    I 3D printed a fan shroud for it and put an old (but surprisingly powerful) fan on there, and that worked ok. The issue, though, was that I wanted the fan to be quiet when the GPU was idle, and I couldn't figure out fan control on Linux, so I decided to control the fan speed via an Arduino.

    I took a spare Arduino, some wiring, and despite never before programming anything for Arduino, I managed to hack this together: https://github.com/askiiart/k80-linux-cooling

    It takes the GPU temperature, turns that into desired fan speed, then sends the desired speed to the Arduino over USB. The Arduino just controls the fan speed via PWM.

    I bought a Tesla K80 for ~$200 off eBay, and now it's going for less than $150, and you can essentially get the same but just 1 GPU for $100. It has 12 GB of VRAM, and works great for "medium-duty" machine learning and AIs like Stable Diffusion.

    It does run hot (150W per GPU), and I've had to make a [custom solution to cool it](https://github.com/askiiart/k80-linux-cooling), but it works great considering the price.

    By the way, you can essentially never have an application use the 2 GPUs in parallel in any useful way; I'd suggest just getting a K20X instead.
