[BPI-R4] Power consumption of m.2 to sata adapters

Hello, as I am using bpi-r4 as a SFP+ nas server and router, I experienced “hard reboots” whenever all drives arranged on 2 raid arrays are used or performance tested. As I am using 2pcs of m.2 M asm1166 to 6 sata3 adapters, i checked that they are really really very hot - you can burn your skin in a second. I decided to make my own cooling upgrade and did “adaper” and attach heatpipe to every one of them. I also attached 3 (because I got the heatpipe cooling block for 3 heat pipes) heatpipes on the cpu.

Based on this cooling upgrades, The high sata load operations stays much much longer, even several hours, but at the end the “hard restart” appeared again.

What do you think it could cause the restarts? Does it is possible that bpi-r4 board does not provide enough power for the m.2 to sata adapters? I am thinking about connecting about 1mF capacitors as much close to the m.2 ports/adapters as possible, but I am not sure and thinking about where exactly they should be placed. Do you have any ideas?

The whole nas is powered by 12V/20A and 5V/20A power source, so there should be enough power. BPI-R4 itself is powered using VH-2PIN connector with 12V.
