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.

### ⭐⭐⭐⭐ 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.
