Would like to hear your opinion and ideas for NVMe cooling solutions, most obvious is a heatsink I guess.
First of all is it necessary?
The reviews I've read of NVMe's with pre-installed heatsinks, e.g. WD Black SN750, the heatsink didn't seem to make that big a difference in performance (kind of disappointed). Endurance might be another matter
E.g. from eteknix.com
Solutions?
I've been experimenting with custom made heatsink, but the fixing is the difficult part.Using strips work rather okay, but they take some space and actually easily bent the PCB = puting stress the chip-solderings which in worst case breaks over time!
And of course I insert thermal pads in between.
The WD Black heatsink and fixing:
Got my mind thinking about 3D printing something equal

Also there seems to be different cooling needs of the NAND chips and the controller, the former like the heat, the later don't. Can any contribute with knowledge about this (confirm/deny)?I have a pretty good ventilated system without high-end graphics card, so its easy for the drive to keep up with things in my setup. Without the heatsink, the drive came in at 53 degrees Celcius and 490K IOPS. As comparison, with the heatsink attached, the drive only reached 47 degrees and delivered 500K IOPS.
