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)

Muy contento con el disipador y el kit recibido.El montaje es muy sencillo y el disipador cumple su funcion. Lo estoy utilizando con un Compute Module 4 de Raspberry Pi en un proyecto de clasificación de sonidos en exteriores en el que necesitaba un solución de disipación silenciosa.

The heatsink is good quality, but does not come with screws long enough to attach it to the cm4 while it is in a carrier board. I would still recommend if you have another way of attaching it.

très bonne qualité ! surpris !l'ensemble s'adapte parfaitement , fourni avec des pads de refroidissement , mais attention pas assez épais , donc ne pas hésiter a en poser 2 l'un sur l'autre pour le contact avec l'emsemble !sinon tout bon !

Looks great, but will not work on big tree tech pad seven that was what I was hoping to use it for

Excellent passive cooling for a Pi CM4. Couldn't be happier.

I purchased this to cool a Raspberry Pi CM4. While the heatsink is well designed, the thermal pads are not. It’s as if they knew this, because they included enough material for two applications. The material does not separate from the plastic backing cleanly and more often than not, splits or tears. As you can see from the photo, it was very frustrating. It may have been related to temperature as it just got worse the more I worked with it. I wound up balling it up and smearing it back on the CPU. Definitely not ideal.

As you can see in the picture, included hardware works and mounts up fine when using a carrier board. Maximum temp in a stress test stays below 50c. Get this heatsink if you want to keep your CM4 cool!

I bought one, and then bought four more, because it was the best option I could find. The product has two flaws:(i) The bolts are too short. I solved this problem by buying longer bolts separately (M2.5 x 18, or M2.5 x 20 if the case has enough clearance).(ii) The "feet" are slightly too short, and this causes the CM4 circuit board to flex slightly when the heatsink is fastened down. I think the amount of flexing is sufficiently small that it should not damage my CM4. I currently have this heatsink in use on two CM4s, and have not observed any faults yet (after ~ 2 months). I considered putting thin shims under the feet (to prevent the flexing), but I worried that the heatsink might not be close enough to the top of the CPU if I did that. At least when it flexes, I know it is making contact.

It's rather clearly just a cast part with next to no machining. Whole thing is powder coated, so for best results, file/sand/ect the coating off the SOC riser. The thermal pad that's supplied is actually not terrible, though I did switch out the SOC pad with artic silver after awhile. Average SOC temp with thermal pad was ~40°c (no heatsink it hovered around 60°c), with artic silver i haven't seen SOC temps exceed 38°c under decent load. Overall, great product and the tiny "cons" are well justified for the low cost.

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.
