Hello.
I am testing the X1004 board with different NVMEs and the temperatures seem high with most drives ...
I wanted to make a 2x 4TB setup and I was looking at eider WD Red SN700 4TB or Samsung 990 PRO 4 TB, now testing mostly with the WD red 4TB.
// I am aware that the speed specs of these drives are overkill, but I need the 4TB capacity and some reliability so I don't lose data.
Booteed from sd card, no activity on the NVME, the temperatures are:
WD Red SN700 4TB gen3: idles at 49-51C
Kingston DC1000B 500G gen 3, idles at ~51C
Samsung 970 PRO 500G gen 3, idles at 35C
Samsung 970 EVO 500G gen 3, idles at 35C
Samsung 990 PRO 4TB gen 4, sealed in box, not tested yet
I have the active cooler too and I seen the drive above that hole in the PCB is hotter by ~3C
I don't know if the hight (50 ~ 55C) temps on most drives is normal or there is something else I can tune ? Maybe something to send less power to the NVME drives ?
Because this board runs at relative small speed, it doesn't make sense to me for the drives to get hot.
I dind't test the Samsung 990 PRO 4TB (gen 4) yet because I wanted to return it, not sure if I should expect it to run hotter because is gen 4 not 3, or cooler because the 970 PRO and 970 EVO run the coolest. If anyone tested the 990 PRO and runs cool, I will unseal it and test/keep this one instead of the WD red that runs hot.
Any thoughts on other things to try ? enabling / disabling dtparam=pciex1_gen=3 in /boot/firmware/config.txt doesn't seem to make any difference.
