+# Universal K80 Cooling
+
+This will determine the speed your fan (connected to your Arduino) should run at based on the highest temperature 
+between your GPUs, then will send that speed to your Arduino. 
+
+---
+
+### How to use
+1. Connect the Arduino to the fan according to this diagram:
+![https://create.arduino.cc/projecthub/tylerpeppy/25-khz-4-pin-pwm-fan-control-with-arduino-uno-3005a1](Images/arduino-fan-diagram.png)
+   1. #### Connect to the PWM wire, not TACH as is shown there! The color may change depending on your model of fan!
+      1. Sorry for not making another diagram, I couldn't find any decent way to do so. Once I make a new diagram, I'll 
+2. Connect the Arduino to your PC via USB, then find the port it's on and **set the port variable**. 
+   1. Instructions for finding the port are in the Python code.
+3. Revel in your success!
+   1. If you plan to use this constantly, make sure to create a service that starts the Python code on boot.
+
+### My setup
+I use [this](https://www.thingiverse.com/thing:4960323) 3D-printed fan adapter for my Tesla K80; I highly recommend it.
+
+In the long-term, I'm planning to build my own front cover for my PC case (a Corsair 175R), and will have a spot for my 
+Arduino and wiring in it.
+
+Pictures will be added later once my setup is complete. Don't expect it to happen anytime soon, though.
+

+
+### Notes and Limitations:
+ - This currently **only supports NVIDIA GPUs**
+ - This currently **only supports normal PWM**, not delta PWM
+ - **You will need to set the port of your arduino manually** (in the Python code as the `port` variable)
+   - There are instructions on how to find the port in the code
+ - Your **fan may use a different color scheme** for its wire, or have a black color scheme. Be sure to 
+Google a diagram first.
+ - You may need to change some variables in the Arduino code depending on your fan's specifications.
+   - Try looking up a datasheet
+ - This was designed for an Arduino Uno, and should work on one. I don't know about running it on anything else, though.

+- Python-Arduino communications library - [pySerialTransfer](https://github.com/PowerBroker2/pySerialTransfer)
+- Arduino PWM fan control - [25 kHz 4 Pin PWM Fan Control with Arduino Uno](https://create.arduino.cc/projecthub/tylerpeppy/25-khz-4-pin-pwm-fan-control-with-arduino-uno-3005a1)
+  - This is where I got the arduino-fan diagram from.
