When I installed the 512GB Samsung 950 PRO, used a much lower cost & reliable solution.
Rather than sitting a $300 NVMe SSD on a hot motherboard (throttling is the case with mSATA models also), I used a $13 Sintech PCIe adapter with included small fan attached, blowing air directly on the SSD, can be found on Amazon. Speed can be adjusted via a knob & should fanwears out, can pick up another on eBay for $5 or less (may as well get a couple). This keeps my investments cool & has never throttled.
HWMonitor always shows the Samsung 950 PRO NVMe SSD to be running under 36C & this PC has been running hard for over 12 hours.
Have a second setup the same way, only a (normally) warmer 240GB MyDigitalSSD BPX NVMe SSD in another build, temps sometimes reaches 42C, but no higher. It was near 70C on on the Sintech adapter with fan switched off, my mistake in turning the knob the wrong way. Temps dropped to under 40C within a minute after turning the fan wide open. On the build with the Samsung 950 PRO, fan speed is set to roughly 50% & temps are holding steady.
One can most likely purchase at least 5 of these low cost PCIe adaptors for the price of one of Cryorig solution. It sure does look cool, but don't see it fitting under all GPU's, and there's no promise it'll outdo a good old fan blowing air direct onto the NVMe SSD. Anyone with a spare x4 lane can use the Sintech PCIe adapter, or in my case, used my second GPU lane, the performance hit (running at x8) is hardly noticeable.
Those with CPU which has 28-40 lanes (or more) on a capable MB will easily find a x4 slot to be used for this purpose. I'm not spending $300 for a NVMe SSD & another $60-100 to cool it (if this solution proves to drive temps down & works across the board as intended). Have doubts it'll work as well as a fan. The answer is simple, get it away from the hot MB for under $15 per NVMe SSD & enjoy many more years versus having these running hot.
We'll see if Cryorig can get these drives to run below 40C passively under the hardest loads possible. HWMonitor is an excellent tool to monitor temps, Speccy and some other utilities cannot measure NVMe temps & other specs.
