Just think, WWLD

I'll get my cable ties!

Nice thing is that you can request one for free.

I had bought a pair of Noctua NH-D9L's for my server. A future server I'm currently buying parts for uses the Intel Narrow-ILM mounting holes. I sent Noctua a e-mail asking for the ILM mounting hardware and all they asked for was proof-of-purchase.

Only drawback is the gear doesn't come with instructions so I'm going to have to kind of guess as to how it goes together or find them online.

Not sure I can be bothered to dig out the proof of purchase, easier just to buy the kit.

Fitting isn't difficult, at least on square 2011 dunno if same on narrow as not come across that. Screw posts into socket. Screw mounting bar onto posts. Screw heatsink onto mounting bar, Cut fingers trying to put fans back in place.

Posts in board, screws in posts, bars on the...then wtf is the rest of this shit for?

That looks... different. Let me go check my D9L. It actually is server version so came with 2011 mount on it already, but assume kit modifies consumer version to same.

It's kinda coming back to me now looking at this. You need to unscrew the existing mount bars on heatsink and replace with the ones matching your socket. Then use the screws and springs to screw top down into socket. The mechanism on the bigger heatsinks in the range is a bit different from this.

That makes sense of some things. It's identical with the exception of the shape of the bar. That means they sent me 2011 & 2011ILM.

I wonder why the 2011 mounting hardware you have is so different compared to what comes with the cooler.

The cooler pictured above is the server version of the D9L, but apart from the mount it is the same. Think it is this one:

Yeah I have the desktop version: Noctua NH-D9L

The screw holes on the cooler itself still line up with the server version so it won't be a problem for me.
