Unfortunately, I was not able to install the stock SN750 heatsink. I Pulled the SSD out, and then put the heatsink on... Gigabyte's backplate on the B550i doesn't have enough clearance. It wouldn't go back into the M.2 slot. I'll probably get some zip ties and a thermal pad and attach the front of it onto the drive later, or maybe pull the backplate off, and use sandpaper to widen the slot so the cooler can fit. It's literally off by ~ .5mm which is pretty maddeningWere you able to install the WD heatsink on the m.2 installed on the back of the motherboard? Do you have before and after temps?
Also, what is the clearance back there for a m.2 heatsink? Curious to know, so that I can search for aftermarket ones that will fit.
Semi-concerned about sticking a hot SN850 into the rear m.2 slot on the motherboard.
But I did take real-life measurements. The clearance for a rear m.2 heatsink is:
- 6mm (total height from the top surface of the SSD's PCB to the top of the heatsink)
- 8.2mm for the TOTAL SSD + heatsink thickness (including the backplate on the SSD for a 2 part heatsink)
- Take care that the M.2 drive heatsink does *not* push the riser cable against the GPU backplate, as that could affect cooling of the GPU Backplate! If you follow the guidelines above, that should *not* be an issue.
- Total clearance will depend on how tall your motherboard's rear m.2 slot is. (if they are lower profile, you may have more room)
