Well this is...interesting:


Reminds me of the old sound cards with joystick ports.

Seems like the new Crucial T700 is working ok with just a heatsink. Does anybody have it?
I have one, but it's not a week old yet. I have the 4TB without a heatsink. My motherboard has cooling for M.2 drives and it works well so far. I figured I could order a heatsink, if things go south.

I just ordered one, it is arriving tomorrow.

Just 1 TB one to use in a small server. I got the version with a heatsink.

I am also going to be looking for one for my home / gaming system. I will probably also go with 4 TB version (up from 1 TB I have now). Some of these games are taking a ton of disk space. I noticed Starfield will take 125 GB...

Still throttles even with bulky coolers with fans:


One of those coolers is basically a small GPU cooler. M2 was never designed for such weight, bulk, or clearance.

Also unlike CPU sockets which are standardized, there's no standard for M2 thickness or component height. It's luck whether a heatsink makes contact because NAND chips can be a different height to the controller. You might even have uneven components on the bottom.

So you'll have air gaps even with a thermal pad, like my Samsung. What's next, thermal paste? Lapping the chips? Delidding? LMAO.

It's a catastrophic failure when a 10W device with a GPU / liquid cooler still throttles.

People say "that never happens in the real world!" Wrong. A game that constantly streams data will potentially do it because it hammers reads. Rage makes my Samsung throttle after 20 minutes. And with DirectStorage, expect these things to be gaming furnaces.

I haven't read all the posts, so just in case no-one's mentioned it:
Drives running the 4Kn SECTOR (not Cluster) size, rather than 512e, seem to be running cooler from what I have read.
ie:
Converting your SSD to its native K4 sector size, rather than have it emulate 512K sectors may well mean a usefully cooler drive under load.
Less processing = less heat. (and less time)

Once your sector size is maxed out, know that NAND is written in Pages.
Pages used by be 4K, (the windows default) but have grown to 8K, 16K, etc.
Setting your cluster size to equal your NAND's page size may well have a similar effect.

Naturally all Partitions, sectors and clusters need to be aligned.
Thats a subject in itself. Especially as most drives now employ a pSLC cache (to spead up writes mainly), meaning 2 different Page and Erase Block Sizes to align to.
Newer Windows versions do an adequate job of alignment, but there's more performance to be had here IMHO and should again result in a bit less processing.
eg: https://askubuntu.com/questions/314262/partition-alignment-confusion

I'll leave it to you all to research the truth of this and perhaps experiment.

Yeah, a lot of HDR monitors with local dimming have a fan, especially if they also have gsync. Manufacturers gloss over it and usually only the detailed reviews mention it.
never owned one but I'm guessing the hdr portion of the monitor makes the pcb very hot?

Another day, another Gen 5 cooling monstrosity.

I call this one the "tower wind tunnel". Also the SATA connector for the fan nullifies yet another advantage of M.2 ("no external cables needed!").

They couldn't just go for a simple 4 pin PWM that you could potentially control via a motherboard header? It would still be an annoying cable, but the potential to have one less connector attached to your PSU, if you have the available motherboard fan headers...

Because if you buy a cheap board, no optional fan headers (or they've put the header as far away as possible).

Cheap boards don't have Gen 5 slots though, right?

I'm sure they will do (no idea if they do already). Whatever looks like a sales point, then cheap out on the fine details.

But then you just use a splitter, fan controller, or adapter, just like you would if you didn't have enough headers (or well placed ones) for case fans.

Fair point, though most hardware design companies faced with the choice of which power connector to use (and are trying to save as much money as possible) are going to go for the likeliest item that every desktop user will have spare; even the cheapest PSU you can find will have spare SATA/molex power connectors spare (the one I have here, labelled a "Pemtium power supply" [sic] from CiT has three SATA power connectors).

I can kinda see the point of that.

Id like to add some more nvme drives to my PC but I'm out of m2 slots and I'm also out of PCI lanes so sharing the ones with the GPU seems not a bad idea.

Why not put a fan connector on the M.2 and power its own fan from PCIe power? There should be more than enough amps available to power a tiny fan...
