TEC1-12715 12V Peltier Plate Module (Peltier 12V 40x40)
Thermoelectric coolers (TEC or Peltier) create a temperature differential on each side. One side gets hot and the other side gets cool. Therefore, they can be used to either warm something up or cool something down, depending on which side you use. You can also take advantage of a temperature differential to generate electricity.

This Peltier works very well as long as you remove the heat from the hot side. After turning on the device, the hot side will heat quickly, the cold side will cool quickly. If you do not remove the heat from the hot side (with a heat sink or other device), the Peltier will quickly reach stasis and do nothing. We recommend using an old computer CPU heatsink or other block of metal to pull heat from the hot side. We were able to use a computer power supply and CPU heatsink to make the cold side so uncomfortably cold we could not hold our finger to it.

Note: It is imperative that a heat sink is used on the hot side of the module. Running the module without one can cause damage to this part. If it’s too hot to comfortably touch, you’re in the danger zone!

Fan SHIM for Raspberry Pi (Fan Shim)

Make your Raspberry Pi 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.

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.

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.

Oh, and it's compatible with our new Pibow Coupé 4 case for Raspberry Pi 4!


  • 30mm 5V DC fan
  • 4,200 RPM
  • 0.05 m3/min air flow
  • 18.6 dB acoustic noise
  • Friction-fit header
  • No soldering required
  • RGB LED (APA102)
  • Tactile switch
  • Basic assembly required
  • Compatible with Raspberry Pi 4 (and 3 B , 3 A )
  • Python library and daemon

Kit contains

  • Fan SHIM PCB
  • 30mm 5V DC fan with JST connector
  • M2.5 nuts and bolts


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.


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.


  • When mounting or detaching the fan, or assembled Fan SHIM, do not push on the fan itself, as it is liable to break.
  • Not heatsink-compatible!
  • Dimensions: 45x39x11mm

ICE Tower CPU Cooling Fan for Raspberry Pi 3/4 (ICE tower)

Please Note: Raspberry Pi is not included. Picture is for illustration purpose only

Meet this super ICE Tower CPU Cooling Fan for Raspberry Pi! Tower structure, 5mm copper tube, multi-layer heat sinks, 7 blades powerful fan, all the above combinations make this super radiator for Raspberry Pi. In the case of overclocking, it can reduce the temperature of the Raspberry Pi from 80℃ to 48℃. What amazing! Best of all, this cooling fan supports the new Raspberry Pi 4 Model B. In our actual use, we found that Raspberry Pi 4 has a large amount of heat. with the help of this super fan, the powerful performance of the Raspberry Pi 4 will be fully released.

Please Note

In the heat dissipation test mentioned above, the temperature was lowered from 80 ° C to 40 ° C. The test conditions are as follows: 1-Room temperature 25 ° C  / 2- Apply silicone grease directly to the heat sink and processor chip  / 3- Raspberry Pi 4 processor

If you use the thermal conductive tape included, you can reduce the temperature from 80 ° C to 48 ° C under the same conditions. It can be seen that the use of silicone grease is better. If you want to achieve the best heat dissipation, we recommend that you purchase silicone grease.
