I wanted to improve the cooling on my northbridge and I like Enzotech products. However they are not factory compatible on the P45 chipset spacing. So I used my grinder with a thin kerf cutting disk to notch the CNB-S1 so that I could use on my mobo like this:

Here is a shot with the 4-40 screws prepped for install and tim applied. You can't use nuts to hold the bolts to the mobo due the low height of the mounting tabs. I had to place a folded napkin underneath the mobo to hold the screws up until they were tight enough to pick up the mobo and crank down on them.

Lastly a overall shot showing all the mobo cooling.

I did almost the same thing on a P5Q SE. I used the round Enzotech northbridge heatsink (don't remember the part number), which comes with a mounting adapter that has holes which match the mobo exactly. It also came with a 40mm fan mount, so I attached an ultra quiet 40x40x10 Scythe "mini-Kaze" or something like that. I moved the stock northbridge heatsink to the southbridge, replacing the little piece of aluminum that covered it.

I bought a couple of those square Enzotech heatsinks wanting to do what you did, but when I couldn't get the pushpins to fit, went to Plan B above.
 
You would have been better off with the SLF version as it has active cooling on it. It's gonna need a fan to cool it optimally.

I have a Sunon 40x20 fan, the same as Swiftech uses for their MCX-159 NB cooler. This model has taller fins for better cooling capacity.

More Enzotech goodness. I only have a 4.5Ghz Dual core, but my mosfets are not even hot, merely warm without active cooling!
