Cool video.
How close does the new heat sink and fan come to hitting the frame at the front?

With cutting the track, is that the track to the 7805 voltage regulator?

Quite close 
But it's stable. For the installation bit, I pushed Y forward as far as I was comfortable (it was over the platform edge) and there was still plenty of room for the heatsink and fan assembly. It is a little off-center, though, or it could hit the frame at left. This seemed to be the only orientation (other than underneath, which doesn't jive with my "heat rises" OCD, and couldn't be easily ziptied) that fit and allows the case to be put back on.

It's between the USB "VBus" and Sanguinololu's 5v rail. Reprap wiki notes this as a possible bug with rev 1.3a. There SHOULD be at least a diode (USB Specification recommends better) but cutting the trace eliminates any possible current dump due to slight voltage mismatch between the 7805 output and the USB supply, which is inevitable. Even under general EE tolerances, this could produce as much as over a watt worth of pointless dissipation which probably the 7805 would get the thickest shaft for. The drawback? The solidoodle needs to be plugged in for USB communication.

I thought Dubstep was all the rage.
Why did you put the heat sink on the front of the motor rather than the bottom? It fits on the front, but there's no worry about hitting the case if it's mounted below.

Dubstep isn't fast enough
Re: Heat mods video
If your extruder gets clogged and starts shredding filament and skipping steps, maybe you could use dubstep then.

Funny you say that...I swear my prints looks better when I have my bass turned way up on the z5500s...who knew that would be the solution to the z-banding issue...j/k
