140mm x 140mm x 25mm
So yes, can fit anywhere and everywhere a standard 140mm PC fan will fit (same mounting dimensions/geometry/holes/etc). They're also compatible with 120mm mounts/holes/etc, if there's enough space for them. I've used them in many systems, including the one listed in my profile PC specs (2 on CPU cooler, 2 front intake, 2 side intake, 1 rear exhaust, 1 top exhaust), they keep the inside of the box surprisingly "cool" even when running hours of nonstop torture/stress in a 35C ambient.

Rated airflow (~3000rpm) = 269.3 m³/h = 158.5 CFM
Rated pressure (~3000rpm) = 10.52 mmH20 = 0.15 PSI

Rated 800~3000rpm, the rotor geometry is balanced so that fewer rpms will diminish airflow at a faster rate and air pressure at a slower rate. Meaning they're optimized for enclosed rack environments, they push hard instead of pushing more.
They can be forced to spin down to ~400rpm (hard on motor) but then they sound like choppy little helicopters.
They can be overvolted up to >3600rpm (hard on motor and on bearing) but then they sound like little space shuttles.

Beware that at full rpms they draw 0.55A @ 12V = 6.6W each.
So basically only one fan per (1A @ 12V = 12W) mobo fan header, if you want a bunch of them in a push-pull rad setup then you'll need a bunch of mobo fan headers and/or other fan controller hardware.

The 2000rpm version is a far better choice for sane people, much quieter and much more power efficiency.

What case?
What MOBO?
What CPU?
What GPU?

Personally I got better performance from the Corsair ML Pro fans that draw a lot less current.

What are you using for the primary cooling? air only? You don't need high pressure if the fans aren't on a radiator. Just enough air flow in the right places like inlet blowing into the GPU and an inlet in the rear to the CPU. Then out the roof.
Case comes native with 3 in the front or intake and one out the back for exhaust the would give you positive pressure and allow the excess to be pushed out the top and other open areas.
Looking at your case (nice one too!) its meant for WC with two rads where the pressure is more important than flow.

If I was you and I was going for air cooling Id buy 3 more fans to go out the roof and reverse the rear fan to be an inlet and leave the front as is.
Unless you just want overkill and different fans. Ive tried the Noctura fans and not a big fan of the fans....uh what...yep. There is one place where they made a difference for me and that was as a replacement for the fans in my NAS because the stock fans were horrendous in both air flow and noise levels in a Synology DS3018XS. The 7200 rpm drives are loud enough, dont want fans that can drown that out!

You CPU cooler and its fan are much more important, what are you using there?

Thanks for responding Justin!!! I am using Asus ROG Ryujin 360 AIO with 6 Noctua NF F12 industrialIPPC-2000 PWM on the radiator.
