Crucial T700 Gen 5 SSD Throttles Down to HDD Performance Levels Without a Cooler
Crucial T700, the company's flagship M.2 NVMe Gen 5 SSD, runs hot—like every other drive based on the Phison E26-series controller (such as the Corsair MP700). ComputerBase.de discovered what the drive does without some sort of cooling. The E26 controller has a Tjmax value of around 86°C, and what happens when it's reached depends on the drive in question. The Corsair MP700 can turn itself off to protect the controller—something that will definitely cause your machine to hang with a BSOD.
The Crucial T700, on the other hand, aggressively throttles down the controller in an attempt to lower temperatures. While the drive won't stop (and your machine won't hang), its performance drops to hard drive levels, with CrystalDiskMark (CDM) measurements pointing to around 101 MB/s (of course, with much lower access times than a HDD). Both Crucial and Corsair offer the drive with large heatsinks, and recommend users to use them. This should severely limit the adoption of Gen 5 NVMe SSDs among notebooks, where the notebook chassis has room for only bare drives. However, some OEMs specializing in larger high-end gaming notebooks and desktop-replacement workstations, can find ways to connect the drives to the notebook's main cooling system using flattened heatpipes. You can catch ComputerBase's review of the MP700 in the source link below.

I know that M2 is slim and fit for laptop. But, proper 2.5" would for sure be easier to cool down properly? Or I am mistaken?
We back to there crucial c300 64 gb ssd. That was my very first ssd and the first from. Since then I have had several from them and from Samsung as well. I have not had a single failed ssd ever.
But yes nvme ssd gets hot and the Samsung 980 pro i have is no different amd that's only a Gen 4 ssd. With out a cooler, thermal throttle is garantied.
The heat is caused by the high speed nvme ssd's are capable of. It put more stress on controller and nand chips than like a sata ssd. Thar will give more heat.
I've just installed my GIGABYTE GC-4XM2G4 AORUS Gen4 AIC Adaptor
It is basically a "simple" PCB for 4 SSD with a 1kg copper heatsink with a fairly silent 5cm fan (which has high/low/off modes)
I like it so far, even if I only can use 2 slots of the 4 because my mainboard can only give 8×/2×4 lanes for the first two 16× long PCIe slots (GIGABYTE X570S AERO G)
On the effectiveness: my Samsung 980 PRO 2TB used to operate around ~50°C idle in PCIe v4 mode, and got into the 60+°C (and throttle territories) when I started using it.
It had a big heatsink from the mainboard, but the RX 5700XT and now the RX 7900XT's cooler just covered most of it, so it got hot fast....
With this adapter card, it is in a comfy ~35°C range and after a full atto or Cristal-disk benchmark it hit only 44°C
I am aware that my GIGABYTE GC-4XM2G4 AORUS Gen4 AIC Adaptor is "only gen4"
But I am sure someone will start producing a similar card for PCIev5.0 motherboards, and these option will be more effective in cooling your SSDs
I just wish/hope AMD will start adding more lanes for mainstream processors 32~48 or even more PCIe lanes than the current 24 pre Zen4 and 28 with Zen4
Sadly me and the most of us cannot afford a Threadripper system...
Would be nice to have at least 2 full PCIe 16× card slots where I don't need to turn off other parts on the mobo

But we can't have nice things.
I wish they'd make MLC drives, which I could use as system drive and TLC would be for storage.
A nromal HDD consumes power too and releases it in the form of heat. Drives could go up to 60 degrees in summers. Thats where it started to get dangerous when HDD's where too hot to touch. Was never any different.
I don't get why they decided to abandon SATA instead of improving it, and went for M.2 instead of pushing PCIe or even U.2 to their mobos. Instead of making use of the case they want everything on a single board.
All this gaming trend in computers is dumb asf, and since every major manufacturer is devoted to releasing these products there are no alternatives for a similar price.
NVME is directly linked to the PCI-E lane or bus. It offers far more bandwidth then S-ata could ever do. S-ata is still supported but no longer continued as in development.
Obviously your going to use a NVME SSD now and in the future and not back to S-ata which is limited to only 500MB a second in regards of read or write speeds.
As I've found out in the Corsair review, I still think it violates the the design rules by being too hot, while consuming very high current pin, thus making it a hazard. There are no documents, that prove that the M.2 slot is already improved when used fanless and can withstand more than 0.5A of current per pin @~50C.
Nevermind, we got MOAR RGB with glass and tiny M2 instead :)
Everything already coming overclocked out of the box.
The secret sauce is that You just need to locate them away from the GPU cooler.
I've had SSD throttling effects for years, even with Gen 3 SSDs with a pair of 970 plus 2tb. Those 2 wouldn't get so hot, maybe mid-high 60s.
The day that I find a laptop that can link the laptop heatsink to the SSD, is the day that I'll buy that model.
