“I find this heatsink very robust and with not too heavy CPU/Memory activity, keeps just warm. The Pi4's are in use 24/7 so reliability is important. There are no moving parts with this heatsink cas - I have had problems with fan failures over time with other active heatsinks.
Ideal for servers, not so good if the GPIO header is to be used as 40 pin extenders are needed for HATs and some padding material is needed between the heatsink and a HAT to avoid electrical contact.”
“A nice and high quality heatsink but with a pretty glaring clearance issue for the GPIO pins.
The case is hefty and nice but the 40 pin connector isnt given enough space for ribbon cables without using a way too large extender piece. If it gets a rework for pi5 id really like to see that fixed and wouldnt mind a few mounting points for a fan, but thats an extra.”
