Penta SATA HAT is now available
Sorry for the late reply. As far as I know, the Raspberry Pi doesnāt support booting from a device on a switch.
Hello - is it possible to confirm that the physical design of the Penta SATA HAT for Raspberry PI has NOT changed?
In both video reviews, the creators said that they had to break few fins of the active cooler to fit between the Pi and the HAT, so I imagine there will be a new design at some point.
Since I will follow the 3d printed case from one of the author, Iām worried that if the HAT has been modified, the 3d model might not fit anymore.
Thank you!
Have You tried to use thermal adhesive tape and small heat sink?
@setq what is radxaās response to the JMB585 chip getting uncomfortably hot during operation? Basically every other manufacturer I have seen who sells products using JMB585 have heatsinks installed on them (or has clearance for adding a easily purchased standard sized heatsink). Installing the top board with fan has not made any noticeable difference in temperature. The placement of the JMB585 on the Penta makes it extremely difficult to find a heatsink that will fit as there is only 4mm clearance between the chip and a disk installed above it. I have seen discussions online about the JMB585 dying from overheating (and apparently has no internal throttling for temperature). I was going to follow @geerlingguyās approach and increase the Pi5ās pcie speed to gen3, but in the odroid forums (post above) people suggested limiting the controllers bandwidth to keep its thermals safer.
pokblach I have been unable to find an appropriateĀ¹ heatsink to install on the chip. The chip is 8.5mmx8.5mm and there is probably only space for a 3mm tall heatsink (at 4mm it would probably be contacting the drives, at 5mm it would prevent proper drive seating).
1 - I did find one seller with a 8x8x3mm heatsink, but they cost USD/$15, which seems unreasonably expensive, especially because I believe radxa should have already included at least some cooling solution for the JMB585.
Some pi4 heatsinks fits there perfectly and those are super cheap.
Also search for ācopper plate heatsinkā, those are flat, comes in various sizes, and You can stack them together if this is needed.
Lastly - check out option to get some copper heatpipe, those are designed to transfer heat to bigger radiator/fan somewhere when there is more space. Hint: You can get those extra cheap from laptops and customize them for Your needs, heatpipes can be bended quite easily (but be careful to not damage them).
If You donāt care about warranty then google for Your drive internal images. Most ssds are covered with and are much smaller inside. Removing those will give You additional place for heatsink for sure. Check out if Your drive would benefit from this, only high end ssds comes with metal enclosure that helps with heat as well as PCB that fills whole place. Of course older hdds wonāt apply.
Mine works perfectly on Rock 3A which has two pcie gen3 lanes (2x more than pi5!) and idle temp for JMB is about 60-80āC, hot but not critical. On original case there was fan under the PCB and above drives (top board) that make some airflow. This worked on factory metal case.
Maybe something like this?
Donāt have to be exact size, easy to cut if needed.
