PIMORONI Fan SHIM for Raspberry Pi User manual

Fan SHIM for Raspberry Pi
PIM461
Make your Raspberry Pi 4 seriously cool with Fan SHIM! This
30mm no-solder, controllable CPU fan with RGB LED and
tactile switch will give your Raspberry Pi significantly better
thermal performance. It's whisper-quiet too!
Fan SHIM uses a friction-fit header, so it just slips onto your Pi's pins and it's ready to go, no
soldering required! Note that, due to the height of the fan, if you want to use HATs or pHATs
with Fan SHIM, then you'll need to use a booster header.

- check out his full benchmark blog post.
The fan can be controlled in software, so you can do crafty things like toggle it on when the CPU
reaches a certain temperature. Use the LED as a handy visual indicator to show fan status, CPU
load/temperature, whatever! The tactile switch can also be programmed, so you can use it to
toggle the fan on or off, or to switch between temperature-triggered or manual mode.
You can read some detailed benchmarking of Fan SHIM's cooling performance here on the
Pimoroni blog.
Oh, and it's compatible with our new Pibow Coupé 4 case for Raspberry Pi 4!

Assembly
Assembly is really easy, and will take less than two minutes.
1. WiththecomponentsideofthePCBfacingupwards,pushthetwoM2.5boltsthroughtheholes
frombelow,thenscrewonthefirstpairofnutstosecurethemandactasspacers.
2. Pushthefan'smountingholesdownontothebolts,withthecablesideofthefandownwards
(aspictured)andthetextonthefanupwards.Attachwithanothertwonuts.
3. Pushthefan'sJSTconnectorintothesocketonFanSHIM.
Software
Our Python library lets you control the fan (on/off), RGB LED, and switch. There's a handful of examples to
show you how to use each feature, and a script to install a daemon (a service that runs in the background)
that runs the fan in automatic mode, triggering it on or off when the CPU reaches a threshold temperature, with
a manual override via the tactile switch.

Notes
Whenmountingordetachingthefan,orassembledFanSHIM,donotpushonthefanitself,asitisliableto
break.
BecarefultomountyourFanSHIMonthecorrectpinsonyourPi,withthePishutdownandpower
disconnected.ShiftingitleftbyonepinordownafullrowofpinscouldcausedamagetoboththeFanSHIM
andthePi.Checkoutthephotosinourtutorialifyou'renotsure.
Notheatsink‐compatible!
BecauseFanSHIMusespinBCM18tocontrolthefan,andthispinisalsousedbyI2Saudiodevices,youwon't
beabletouseI2SDACslikepHATDAC,pHATBEAT,andtheIQAudioboardsatthesametimeasFanSHIM
Dimensions:45x39x11mm
