“Ordered my second pi4 with the aluminium heatsink case. Managed to destory the thermal pad trying to peal the backing off (even with tweezers). Contacted Pimoroni and they sent me some replacements the next day free of charge. Such a great company to deal with, I always buy pi related stuff from them because of this. Not sure about the heat sink the temps are fine and it looks much better than the first pi4 with a cheap fan held in place with my sons discarded loom bands (don't you just love kids crazes). Might try thermal paste next time. Bottom line great company to deal with.”
“Look great and protect Raspberry pi Board
But
It does not allow connection of 40 pin GPIO HATs or plugs without using extra headers.
Also - bolts should be longer or have threaded standoffs to allow mounting on touch screen frames or other mountings.”
Ahoy Marco! Sorry to hear that - there's a tutorial for assembling this case here: https://learn.pimoroni.com/tutorial/sandyj/assembling-the-heatsink-case . If you drop us a line at support@pimoroni.com we'll see if we can help with the thermal pads!
“Nice quality finish. Seems to do what it is supposed to. Silent passive cooling and Pi4 temperatures within reasonable level (~63 ºC) even after 15mins of insane cpuburn 4-core tasking. And no throttling! Obviously, heat sink can get very hot when all 4 cores are working but typically hs temperature seem to be below 50ºC as is the ARM chip temperature. Does not block the wi-fi but might attenuate the signal and speed achieved. I was able to reach ~70 Mbits speed @ 5GHz band. I have a 200 Mbps FTTH connection directly to house.”
“This is what I call a heat sink. It weighs 97 grams and manages to keep the 4GB Pi4 at a steady 50 C when the Pi is in normal use as a substitute desk top.”
