I've recently installed the Alphacool Eisbaer LT92 in my Dan A4 V1. Obviously, as the V1 does not have the holes at the bottom for airflow, i've had to drill them myself.
There's been a thread on the fitting of the radiator, and it was said that it (probably) won't fit. Thought i'd buy one, and it fits without any issues! (Altough i did have to swap out one of the fittings to a 90 degree fitting,i've used the the EK-AF Classic Angled 90°).
I did have to cross the tubes as they were too long, so the angled fitting on the motherboard side points to the gpu side. Could also just have cut the tubes ofcourse.

In the above picture, i've fitted a NF A9x14 as that was the fan that used to be on my Dark Ridge, but it has recently been swapped to the NF-A9.
Performance and noise is great, keeping my 9900k cool. I will get some prober numbers later.
