Low profile air cooler for 3U case

[Joust]

Gents,

As far as I can tell, there appears to be a max height of 110mm for an air cooler in a 3u case. I've been running a 3570k in an open case, but I'm moving the entire rig into a more hostile environment and need to close it up.

What is the best option? Noctua, bequiet! Both have low profile offerings. Sound is a non-issue. With the coolers I've seen, I'll need a tornado of wind to make up for the heat exchanger surface area difference. (Currently using a full-size Noctua)

I love my NH-L12s as an actual "low profile" cooler. 110mm is a huge height. You have plenty of space.

I have an original NH-L12 (not the L12s) and it works fine - but mine is just on a non-OCd HTPC i5-4690. I think it could handle quite a bit more, looks like the 12s is the same heatpipe assy, just a single thin fan - adding a second fan to the 12s might up its game a bit if you have the room.
