Coming from the Icy Box Flat (the black one).

I had avoided this one (the Tower) the first time due to the loss of reviews and the fact that it looks bulky and a bit ugly in the photos, while on the contrary, it is a miniature like the SSD (for 2280 it is btw not 2210, Skroutz is mistaken) and quite elegant, and although I was a bit worried it wouldn't fit anywhere in my Asus Prime Z790-A motherboard, it ended up fitting perfectly and has space from the card for the fan to get air, just maybe a little caution when inserting or removing the card because it does stick out a bit from the motherboard (only outward, seriously top to bottom it is very compact, as wide as the Nvme) and it might hit it.
As for the Performance, first of all, I recommend the Fan Control App (which is the only program I know that allows you to set the Fan Curve based on the NVMe temperature, it also works with anything that has a Heat Sensor) so you don't run it constantly at 100% since neither the Bios nor most if not all Hardware Manufacturer programs allow you to set the Fan Curve based on the NVMe temperature.
Well, unlike its sibling, this one is silent (even at 100%), has a Fixed RPM Range (meaning it doesn't change the Max RPM on each Boot), works flawlessly with both Bios and Fan Control App (although unfortunately it seems to only start from 30% and above, specifically the Auto Calibrate of the Fan Control recognized its Range as 1940 RPM with 7500RPM) and "freezes" the disk. Simply perfect (hard to believe it’s from the same company).

It does a very good job, especially in PCI Gen4. The temperature compared to others I had is 10 degrees lower
