SparkFun will be closed Friday 7/3/2020 for the 4th of July holiday. All orders placed after 2 pm MT on Thursday 7/2/2020 will be shipped out on Monday 7/6/2020. SparkFun Support will also resume on Monday 7/6/2020. Have a safe holiday!
Why use a heatsink and a case, when you can use a heatsink case?! This purple, anodised aluminium case for the Raspberry Pi 4 will give you 10-15°C of passive cooling under a full CPU load. This case is great for situations where you want completely silent cooling, like home media centers.
It comes with a thermal pad to provide thermal contact between the CPU and top case, and a handy Allen Key and set of hex bolts to attach the case together.
The case gives you access to all of the ports, pins, and connectors. You can just about get away with using low-profile HATs and pHATs (those without bulky components on the underside) using one of our tall headers, but be extremely careful not to short any components on the metal top case!
Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.
Skill Level: Noob - Basic assembly is required. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Power tools or custom parts are not required. Instructions will be included and easy to follow. Sewing may be required, but only with included patterns.

It's a very neat idea, and initially looks great, but once you actually fit it you notice that none of the interfaces from the heatsink to the chips on the Pi 4 are actually correctly sized or positioned. There are 3 different raised portions on the inside of the heatsink to make contact with the CPU and two smaller chips. None of these are correctly centered, nor sized correctly to make complete contact. Further, they are all different distances away from the chips they are supposed to contact. With the thermal pads applied, only the CPU makes good contact (thermal pad gets compressed). The middle chip's thermal pad does not even make contact at all! The third pad just makes the lightest of contact. It's as if someone just eye-balled a Pi 4, drew up some junk in a cad program, and sent it off to production without ever even testing it.
