I'm crossposting this from the Builds forum as I think there's a good chance that Dan A4 owners will have this cooler.

I'm planning a fairly extensive upgrade of an Alienware X51 R2 that I bought back in 2013. I'll create a post with all the details once I have them finalized (hopefully in the next few weeks).

One of the last things I'd like to change is the loud and fairly poor stock cooler. The height is a challenge, with the current heatsink and fan being only 42mm high, with a shroud fitted that adds an extra 20mm.

I thought I might be able to fit the Alpenfohn Black Ridge cooler with a 92mm Noctua fan, if I'm willing to remove the shroud. The RAM I'll be using is HyperX Fury DDR3, which scrapes in just under the 33mm limit.

I was wondering if anyone could let me know how far the heatsink protrudes from the mounting points in all directions.

Here's an image to show the limited space I have to work with.
