Awesome product. Fits perfectly and works like a champ. My pi is happier now. Thanks! Review: Cool Cooler - Problem solver - Pi 4s can run a bit hot and after adding an accessory board on top of the Pi 4 my unit reported 129 degrees F all the time even without a case. The Radio board I use has an LCD display with temp front and center so I can't miss the issue. This wedge cooling solution with stock heat sinks now runs at 97-98 degrees even under load -Problem solved! Wishes - a little more included hardware would help as the stand offs have too long a screw threads and I've had to cobble together mounting hardware. Also, a high-med-low fan speed switch would be great as I can barely hear the unit and my cooling is likely more than I actually require, so running at 50% fan speed might be a great option. ## Features - 0.91 Inch OLED Display---This is a 40pin Pi HAT type expansion board, which provides a 0.91 inch display screen connected to the I2C pin;The display information can be customized through the program. - Speed Adjustable Fan---It provides an ultra-thin 4007 silent fan to provide heat dissipation support. - Programmable LED Indicator---There are 4 customizable LED lights on the back of the board. You can also control the lighting mode of the LED lights through simple programming. - GPIO expandable interface---The previous HAT board design is used. The 40Pin GPIO can still be easily accessed by users. The new fixing method avoids the risk of short circuit caused by metal parts and provides a good appearance design. - Package Inlcudes---1 x Fan Expansion Board Plus 0.91 OLED V1.0; Note: Pi board is not included! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09MVL8BWQ | | Best Sellers Rank | #1,073 in Single Board Computers (Computers & Accessories) | | Brand | GeeekPi | | Compatible Devices | Raspberry Pi 4 Model B, 3B+, 3B, 2B | | Connectivity Technology | GPIO, I2C | | Customer Reviews | 4.4 4.4 out of 5 stars (61) | | Manufacturer | GeeekPi | | Mfr Part Number | EP-0152 | | Model Name | GeeekPi Fan Hat | | Operating System | Linux | | Processor Brand | ARM | | Processor Count | 1 | | RAM Memory Technology | LPDDR4 | | Total Usb Ports | 2 | | Warranty Description | 6 months | | Wireless Compability | 802.11n | ## Product Details - **Brand:** GeeekPi - **CPU Manufacturer:** ARM - **Connectivity Technology:** GPIO, I2C - **Model Name:** GeeekPi Fan Hat - **Operating System:** Linux ## Images ![Fan Hat for Raspberry Pi 4 Model B, PWM Fan GPIO Expansion Board with 0.91inch OLED Display for Raspberry Pi 4B/3B+/3B/2B - Image 1](https://m.media-amazon.com/images/I/61u-31cTaXL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Get one! *by A***R on December 9, 2025* I don't leave many reviews, but this one deserves it.

You will have to do some coding to get it to work right.
