Has anyone replaced the nb heatsink with a Thermalright HR-05?

Or how about a Thermaltake ES II?

If so, then what are your results?

I'm wondering if the aforementioned coolers would would be more effective than the stock Formula heatsink with a 40m fan. I used these coolers on my old ICFX3200 and still have them hanging around.

Also, are there any issues with mounting a Tuniq Tower on the non-SE version of this board?
