If I were you I would get a fan controller that allows you to switch the Tornado from 12v to 5v, that way you can keep the tornado and up the fan speed when needed, but also have the thing quiet when you dont need it. Myself, I have 2 tornados in my case, and there on full all the time. Its downstairs so I dont have to worry about the noise, and when I DO want to play a game, I wear headphones, so that solves the noise problem
now, onto your FSB. If your running your ram in Dual Channel, take it out and put it single channel, that will help you get your fsb to its max. But if I was you, I would leave the thing at 12x200. Thats amazing for a barton, and well, you have the equivilent of like a 3800+ now, so who really cares LOL. You can try and go for the 12.5x and if she works, thats awsome. I cant seem to get my 2100+ to get to 12.5x, perhaps there is an issue with the NF7-S? If you happen to get it to run stable at 12.5x, let me know what your settings are at. Cuz I know the proc I am currently using can push 2.6ghz (it did on my cuz's epox 8rda+) so a setting of 12.5x200 should be fine for it.
Nice to hear that the M is going good for you tho.
