“Built a NAS with a Pi 4 and started with the standard plastic case and the set of 4 heatsinks (they do look good!) and now with this heatsink case.
My findings (degrees C at idle / sustained write over WiFi ):
Plastic case closed and 4 x heatsinks fitted: 60 idle / 70+ loaded
Open heatsink (case top removed and Pi sitting on its side to allow natural airflow): 50 idle / 60-65 loaded
Armour heatsink: 40 idle / 45 loaded
I've yet to mount the Pi to a drive bay of some kind and neaten things up I doubt it'll have much impact on these figures.
This is a great solution if you want a silent running rig. I haven't measured the effect on WiFi signal strength (I did wonder about all that metal around the pcb possibly masking the signal) but transfer speeds remain the same as with the plastic case. It's easy to assemble the heatsink around the Pi and it looks superb, too!
Drives: Two WD 240G SSD in RAID 1. OS: Ubuntu 22.04 server. Environmental conditions: about 20C, no forced air movement.
Hope this all helps someone else decide what to use for their project!”
“This is the second one I have purchased after the first worked so well I decided to purchase another temps dropped around 20c compared with no heatsink so works well and looks good too”
“great case, keeps the Pi model4 8GB cool and protected, while still allowing access to all the headers, sd card and IO's.
comes with spare heat pads too. Do not over tighten the screws otherwise you will cause the pi board to bend causing potential damage.
over all a great product at a great price”
“Contrary to the instructions, the thermal pads came pre-cut in my package, which was convenient and saved some foutering. My one uncertainty was that it seemed like the two small pads were made of slightly thicker material, again contrary to the instructions. It would be good if the instructions could be updated to clarify this, although it seems to work fine. In the official case, my Pi idled in the mid-40s. Installed in this case, it idles around 30ยบ.”
