Okay so I have my new mobo. I took off the heat pipes ( awesome mounting. I'm Really impressed) and oh hey look... the heat pipe covers and cools what I believe is 2 clusters of mosfet(s). I'm not having awesome success in finding a waterblock kit I can afford or any that say they work with the :XFX. Is it a standard one fits all form factor? I have been buying danger den lq blocks for 5 years, but they don't seem to what I need. ( waiting a reply from tech support).

look right. BUT SIXTY DOLLARS EACH? That makes a mobo waterblock set over 220 with the N/S.

They look right. Not specifically my mobo. Though they are 1/3 the price.
