[Overview] Geekworm design this 12mm embedded armor aluminum alloy heatsink to slove its heat generation problem for the Raspberry Pi Compute Module 4 CM4, This heatsink can also be used with a 30mm cooling fan above. [Key Features] Compatible with Raspberry Pi Compute Module 4 CM4 Motherboard High quality embedded Armor Aluminum Alloy Heatsink Supports to install a 30mm fan to get more cooling down, you can use 3007 or 3010 cooling fan. Heatsink dimensions: 54x39x12mm/2.12x1.53x0.47inch; Net weight: 30g/0.07lb Application Note: the Raspberry Pi Compute Module 4 CM4 Motherboard and the IO expansion board are not included in the packing list. Cut proper thermal pad to attach on the CPU of CM4 module FAQ 1. We get the feedback maybe related with the individual heatsink that use the one piece thermal pad still have gap between the CM4 module and the C235 heatsink, if you meet such a situation, please cut the thermal pad into two pcs and attach 2pcs of thermal pads stacked to attch on the CPU of CM4 module. 2. Or if you find there is no gap between the C235 and CPU of cm4 module, there is no need to attach the thermal pad, you can use some CPU grease(not included) on the CPU chip to get better heat dissipation performance.(Recommended!!!) [Packing List] 1x 12mm aluminum alloy heatsink for CM4 4x PM2.5x16mm Screws 4x M2.5 Nuts 1x Thermal Tape(attach on the CPU of CM4) Review: Excellent! I added a few more thermal pads, and it runs ice cold. - ICE! for your CM4. Almost. No matter what I throw at it on the CPU, it never cracks 55*. Ever. Never throttles, obviously. If it did, I'd throw a fan on it. Barely comes with any thermal pads and the one on the larger chip barely makes any contact. But it does make contact. I have an assortment of thermal pads so I threw them over the entire thing. You do have to screw this down a little bit for some of my larger pads to make good contact, but there's a trick to doing it without having the board bend like other people. First, my CM4 is mounted on a carrier board. There's a small gap between the underside of the CM4 and the carrier board. I filled in this gap with thermal pads of the correct height. This made it perfect! I can tighten it down with no bending. It's beautiful with this mod and runs ice cold. This cools better than a cheap one with a fan (when the fan is off), so I know there's headroom if I wanted to add another fan. would recommend if you're ok with taking a chance on having to order a thermal pad assortment. Otherwise, you probably have about a 75% chance of having it work out perfectly. It was worth the small risk for me since I had all the thermal pad assortments I could ever ask for! Review: A great option for the CM4 - This heatsink works surprisingly well. I had originally given a bad rating because the included installation bolts and nuts that were included weren’t a good fit — I couldn’t make a connection to the carrier board at all with the heatsink installed the way its pictured in the description. But after swapping out the 2.5mm bolts and nuts for something that was a better fit, this heat sink it working great. I’ve had a CM4 fitted with this and a 4010 Noctua fan on top with the CPU overclocked to 2147 MHz for 24 hours now, and it hasn’t broken 40°C. ## Features - Geekworm design 12 mm aluminum alloy heatsink for Raspberry Pi Compute Module 4 CM4; Model:C235; Heatsink for Raspberry Pi CM5, refer to model C519 - User Manual: Google Geekworm Wiki and search C235 to visit the guide - Heatsink Dimensions: 54 x 39 x 12 mm / 2.12 x 1.53 x 0.47 inch; Net weight: 30 g / 0.07 lb - Support install 30 mm (3007 or 3010) cooling fan above the heatsink for better heat dissaption - With one piece thermal pad, need to cut proper thermal pad to attach on the CPU of Raspberry Pi Compute Module 4 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08QMTVCJW | | Best Sellers Rank | #123 in Heatsinks | | Brand | Geekworm | | Brand Name | Geekworm | | CPU Socket | CM4 | | Cooler Heatsink Compatibility | Raspberry Pi Compute Module 4 CM4 | | Cooler Heatsink Material | Aluminum | | Customer Reviews | 4.4 out of 5 stars 125 Reviews | | Item Dimensions L x W x H | 2.12"L x 1.53"W x 0.47"H | | Item Weight | 0.02 Kilograms | | Manufacturer | Geekworm | | Model | C235 | | Mounting Type | Panel Mount | | Part Number | TB-2020-14 | | Product Dimensions | 2.12"L x 1.53"W x 0.47"H | | Warranty Description | 3 months | ## Images ![12mm Aluminum Alloy Heatsink (C235) - Image 1](https://m.media-amazon.com/images/I/61JI8tt9ZGL.jpg) ![12mm Aluminum Alloy Heatsink (C235) - Image 2](https://m.media-amazon.com/images/I/71ttpx44a7L.jpg) ![12mm Aluminum Alloy Heatsink (C235) - Image 3](https://m.media-amazon.com/images/I/71NEtb2ljpL.jpg) ![12mm Aluminum Alloy Heatsink (C235) - Image 4](https://m.media-amazon.com/images/I/711aO2ulG2L.jpg) ![12mm Aluminum Alloy Heatsink (C235) - Image 5](https://m.media-amazon.com/images/I/71wZozU-kgS.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent!

I had originally given a bad rating because the included installation bolts and nuts that were included weren’t a good fit — I couldn’t make a connection to the carrier board at all with the heatsink installed the way its pictured in the description. But after swapping out the 2.5mm bolts and nuts for something that was a better fit, this heat sink it working great. I’ve had a CM4 fitted with this and a 4010 Noctua fan on top with the CPU overclocked to 2147 MHz for 24 hours now, and it hasn’t broken 40°C. ### ⭐⭐⭐⭐ I like this heat sink, EXCEPT (a word of warning) *by R***I on April 18, 2024* I like the compactness of this heat sink, and the threaded holes for an optional fan, but DO NOT USE the pink thermal pads that come with this! The pads will WARP the CM4 module, which will compromise the mezzanine connectors. Instead, use thermal heat sink compound. ## Frequently Bought Together - Raspberry Pi CM4 12mm Aluminum Heatsink/Cooler/Radiator/Protective Shell Support 30mm Fan (C235) - Raspberry Pi 5 (8GB) - Waveshare Compatible Antenna for Raspberry Pi Compute Module 4/5, Supports 2.4G/5G WiFi Frequency Band, External Antenna For CM5/CM4/ESP32, with SMA Male Central Pin Connector --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/419878102-12mm-aluminum-alloy-heatsink-c235](https://www.desertcart.sn/products/419878102-12mm-aluminum-alloy-heatsink-c235) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-04*
