what do you mean rig a fan to it?? like the side of it? where exactly??..
and no i have never used a nitrogen CPU cooler before,
but
1. it sounds overkill.
2. its probally way more expensive
3. you probally have to feed it nitrogen dont you?
4. i never heard of the brand, and unless its a overnight fad, have not heard much about aftermarket nitrogen CPU coolers.
and thats all i have...
