High-performance NVMe SSDs tend to run hot. Ergo you have seen the manufacturers offer solutions with heatsinks, incl motherboard manufacturers making that even easier for you. Team Group takes it to the next level, as they are fitting the Cardea NVMe SSD with a heatsink holding liquid. That's right, that is passive liquid cooling for you.

Review: TeamGroup T-Force Liquid Cooled NVMe SSD
Hello,
I been reading that all NAND Controller manufacturers optimized their firmware to detect PCmark, so when it runs its test the files it creates always stay in the ram portion and then SLC cache without flushing it, basically thats why these benchmark is useless it doesn't represent real value, and by just looking at your score table, all the SSDs are going head to head and have almost identical score.
Its like GPU vendors did the same for 3d benchmarks long time ago, now its NAND time to do the same.
BTW, I also found out that this SMI controllers like SMI SM2262EN etc are "cheating", since most benchmarks they create relatively small files, so controller keeps the files as long as possible in the SLC cache, so benchmark scores look great but in real world scenario when you use bunch of programs it doesn't really help.

Given how hot these things get/how performance degrades with temperature/time, I'd not be surprised if it makes a massive difference. Yeah, 2 GB/s vs 4 GB/s is still stupid compared to even SATA SSDs, but in some applications, that performance matters.
I am dubitative about the use of WC for that thing...

Hello,
I been reading that all NAND Controller manufacturers optimized their firmware to detect PCmark
just like car manufacturers for emissions or less well known euroncap (security can go from safe to deadly if you crash at higher speed than euroncap tests)
more on topic I bought a supposedly copper heatsink you stick on your nvme drive from aliexpress
https://ae01.alicdn.com/kf/H1ec1be81ac5d45248433c6135d8ece57e/New-NVME-NGFF-M-2-Heatsink-2280-SSD-Metal-Sheet-Thermal-Conductivity-Silicone-Wafer-Cooling-Fan.jpg-q50.jpg
and my 970pro (copying a 100Gb file) went from 71°C to 61° or less so I gained around 10°C from a 3$ heatsink not bad, that said I don't think it's that much better than the "plates" recent motherboards like the X570 offer, if you don't have one of those integrated cooling, a 3$ cooler will do something for you
(I shouldn't have to say that but on chinese shops don't buy the ultra cheap stuff it's always garbage, bought 2$ blue light glasses they blocked nothing bought 10$ blue light glasses they block 99%)
another comment I have to make, watch your ssd placement, most motherboards have them below the GPU, very bad idea as both generate heat, I actually moved my gpu in a lower slot to have the upper nvme clear (in the recommended placement the same ssd was often at 90°C)

As the article also says, the water only works as a buffer to smooth out temperature spikes.
Lets guess 5-10 minuttes full load could overheat the SSD, it will then take around the same idle time for the temperature to fall down again, because the water will then keep the idling SSD warm, instead of cooling it.
A solid block of aluminium would also smooth out the temperature in the same way, but the aluminium top would not insulate the heat as the plexi top does, and a solid block would cost less to make.
I am willing to bet on that if you remove the plexi top, the drive would run cooler if full load is longer time then 1 hour.
I see this as, for looks only, personally i would not pay ekstra for it.
