I like ThemoChill rads, but the HW Labs SR-1's might be good for you.

They have better paint, and will most likely require less flushing for initial setup.

T.C. rads can be a real PIA to get clean the first time around, I still favor them however.

Size depends on your case and if they must be inside. I say more/bigger rads = more Xtreme.

I like these fans for 25mm thick. http://www.newark.com/jsp/search/pro...sp?sku=96M1770


Or these for 38mm thick. http://www.newark.com/sanyo-denki/9g...fan/dp/96M7364


You can believe their specs, very good fan's, I own some of each.

These are bare fans however, no pins, DIY.
