50mm size radiators, what are they used for?

[RacA]

Recently, while browsing for watercooling parts I have found quite bizzare, thick, 50mm size rads.
I've been trying to find a reasonable usecase for those parts but I am out of ideas.
Also how a tiny 50mm size fan would push any air through such a thick rad?

Has anyone ever seen a case with a spot for such a radiator?

Photos and name for reference:
"Alphacool NexXxoS XT45 Full Copper 50mm Single radiator"
 

Also they go up to 3 slots, 3x50mm fan?

1u servers I guess?

servers ( thin models )

 

if you look at Alphacool's website you'll see that they have an entire section dedicated to severs

That's it! Now I'm feeling a bit silly for missing this.
This also answers my question regarding how tiny fans are going to push air though such a rad. I bet 10k rpm server fans would do an easy job of it

Only minor problem is that its too tall for a 1U server of 44.45 cm, so I think your question is still valid. IIRC alphacool had a separate series for 1 U servers.

Computers aren't the only thing that are water cooled. I recall seeing a project years ago where these small radiators were used in RC vehicles.
