I know this thread is old sorry.
I had a TE CPU cooler that had a bay controller and when I built this PC I could no longer use it and miss having all that information at my fingertips. I finally decided sense my MB supported one I'd get one and everytime I found one I didn't have the extra $$ and if I had the extra $$ they were out of stock LOL I finally found one and ordered it but was told it had to come from ASUS so it would take an extra 7 to 14 days to get it did I want to wait... ahhh YEAH! I'll wait! LOL anyway when it comes in I'll let ya know how it works on a Crosshair IV Extreme
