Who does not care to search - cooler height is 53mm, 38mm heatsink and 15mm fan.

Goshdamn that looks good for some of the sandwich-style mITX cases on the market.

Lookin good for the ITX crowd for sure

pretty lengthy coldplate, wonder if its done that way for Alder Lake

ZoneDymopretty lengthy coldplate, wonder if its done that way for Alder Lake

I doubt it, Alder Lake actually looks more square. It's Rocket Lake that is the longest/thinnest design we've seen in ages because of the extended Xe graphics, and that still fits (just) under a regular LGA1200 IHS.

It's probably just for ease of manufacture. They could either undercut to reduce the amount of surface that needs machining/polishing, or they could just machine/polish the whole lot. There's probably very little difference in machine time and cost between the two options.

EDIT:
Pricing on AliExpress is reasonable, $43 for black vs $37 for unpainted with a grey fan.

Looks like the Noctua NH9

Caring1Looks like the Noctua LH9

I hate the Noctual LH9 series. They don't use the good secufirm system (space constraints) and they are socket specific, so I had to throw out my old intel-socket LGA115x NH9i when I went AMD.

As coolers they were fine, and good quality but my NH-U12 is still in service after, uh, 12 years or something like that.

It's alright, better than the noctua LN9a but thats much thinner.
If you only have 53mm, it's about as good as it gets .
If you can get a tiny bit more space, the ID cooling IS 60 is a better option,
Note the IS60 evo, is not the same thing, and its 63mm tall..... its the IS 47 with top fan.

btarunrhydraulic bearing fan.

isn't that marketing words for Rifle bearing ?

Alder Lake isn't that big, 37,5 x 45 mm for the entire CPU, take away 4 mm on all sides and you roughly have the IHS size.

There isn't a cooler already out there that won't fit Alder Lake.

In this space every cm is effectively a different class of cooler. Roughly <40mm, <50mm, <65mm but of course this varies alongside the common case clearances.
NH-L9a/L9i are 37mm, AXP90-X53 is 53mm, IS 60 is 55mm.

Keeping many of these coolers at 92mm fan size is deliberate as well - this fits into the standard cooler clearance limits around the CPU socket and will not cause issues with surrounding components, RAM or heatsinks. Anything that low and larger to accommodate a 120mm fan is likely to have limitations with how they fit on motherboards.

He was pointing at Alder Lake being rectangular instead of square like LGA115x/1200 (37.5 x 37.5 mm). AM4 is also square and not too different at 40 x 40 mm. Both have a few millimeters smaller IHS size.
Coldplate on AXP90-X53 is 36x55 mm, so Alder Lake's LGA1700 actually might have been a consideration. AXP90-X53 came out in October last year when LGA1700 was a recent but known thing.

I have a boxed NH-L9i in my hand and the packaging states it has Secufirm2 mounting kit, and I also have the AMD mounting kit for it.

Huh, fancy that - they've changed their tune. Back when I bought my L9i I remember it saying very specifically that it wasn't for AM3/AM4 and that's why they made the L9a. Just checked some 2013 reviews of it and I'm not misremembering, that's how it used to be - no interchanging and no AMD kit in the L9i box.

If the L9i includes AM4 mounting in the box now, why does the L9a still exist?! :)

L9a is ~15% bigger.

I really like this one, however, I regularly see second hand Noctua NH-L9x65 for 25 EUR or so. And they seem about the same to me. There is no pricing here, but I feel like it will be a tough sell.

I have a chassis I expanded to 6L because I couldn't stand 92mm fan noise. I have all the heatsinks I mentioned.

You misunderstood.
It is the Intel cooler and the AMD mounting brackets are free from Noctua and available separately to enable it's use in an AMD system.

I like it
