Okay so $115 starting out.
If you add 2 more fans, that probably gets to be about $140 ish.
Change all the fans to better fans that are also silent? That could start pushing to $170 ish.
Price:Performance, the NH-D14 and Silver Arrow will wreck the H100, however if all you care about is performance, then sure, by a few degrees, the H100 wins.
Let's stay on topic though, shall we?
Fact of the matter is, the IB CPUs are not going to run as cool as SB CPUs, by the sounds of it, no matter the cooling. If it sucks on air it will suck on water, just less.
