I do not have any real data for temps or comparison, but I do have a 240mm Asetek LCLC system installed in my HTPC housed in an Antec Fusion Media case and it all looks pretty good. Here is a picture if it helps:

It is not anything fancy or elaborate, but better than any coolers I could fit in the case due to its short height. It DOES beat a Scythe Ninja Mini for what that is worth haha

And I ordered the Asetek kit off NCIX, here is the link:
