My own searches did not yield any results on adaptations of the Icewind Dale video game series' story into pen & paper adventures. All I could find were adaptions for other video games like Neverwinter Nights.
So, have their plots ever been converted into a published campaign, adventure modules, or adventure path that is compatible with D&D 3.x or Pathfinder? I don't think there is anything official, but maybe there is something fan-based?
The Plane Above is the 4E sourcebook for the Astral Sea, and includes a paragon-tier "mini adventure" set in the Astral Sea, as well as other adventure hooks. The book is about 150 pages, and the adventure is only a half dozen of those, give or take. The Manual of the Planes also spends about 30 pp on the Astral Sea, but there are no adventures. I believe there may be some hooks.
There are sourcebooks from previous editions that cover the astral plane, most notably 2E's Planescape's A Guide to the Astral Plane (which does not contain any premade adventures). The cosmology of 4E differs drastically from that of previous editions, however, and the Astral Sea of 4E is quite different from the Astral Plane of the 1-3E "Great Wheel" cosmology.
To the best of my knowledge and research, there are no adventure modules published by Wizards or TSR that were set in the astral anything.
I've verified this using microsoft paint. First, note that 1 mile is 63 px wide:
Next, I found the nearest-to-horizontal stretch of road, just east of Torgos and measured four dots:
Also 63 px wide.
So four dots on the roads represents one mile, or 1/4 of a mile per dot.
Note, astute readers will be keen to avoid a fence post error; the 63px segment consists of exactly four whole circle diamaters.

I have a fairly comprehensive collection of the official modules and can confirm there were no official adaptations (or any released as web exclusive content). I have never seen a fan module either, though there are a number of threads with people who started to do so in various editions or are running their own variation (a couple examples below).
It might be worth following up on those message boards to see if the participants have content they're willing to share. At a minimum, the threads frequently have official sources of data on the Icewind Dales region at least.
