“Asthetically a really nice dual function case and heatsink. Assuming the silicone pads that fit between the heatsink and the chips have good conductivity then it has to be a winner. The only disadvantages are the ribbon cables are a bit tricky to insert and remove if you're going to want to do that and the SD card is a little exposed. My only regret is that I didn't buy these before for my other Pi's.”
“Nicely made heatsink, makes contact with 3 chips on the pi 4 rather than just the CPU (as on the flirc and coolermaster cases I have). Not sure if they needed cooled or not, but feels reassuring. They also provide two sets of thermal pads for each size which is a very nice touch. I am only using the top piece as I have it on a 3d printed mount, but its nice that the back piece is metal and so should provide good protection.”
“Very high quality. It even feels nice just to hold. It doesn't come with instructions however, so make sure that you apply the foam pads or it won't work. Keeps my pi very cool even when running some demanding stuff.”
“I would prefer it covers the sides a bit better. Overall good thermal performance. Just make sure you read the instructions before installing (on pi hut).”
“I wanted passive cooling, so I chose this as it had protrusions for the CPU and memory and ethernet. I cannot write code, so I used the 'Explaining Computers' web site and copied his code to test the generated heat. Running said script several times on the trot, with an ambient temp in a warm'ish room, gave the highest result as 56 deg c. To my mind a good result. Not only that, but it makes a strong, sturdy case as well.”
