Making of GPU Post 7

Finally got around to modelling the heatsink.
First setup the CV curves and circles so that I could create a pipe that curves around in a certain way.

After that I extruded them.Tried to give them a tapered effect.
I then created a cube and beveled the outer edges, and duplicated it 60 times with a translation on the X axis of -2.I did this twice to make the fin-stack.
I then made the cpu block which is intended to press the heatpipes securely against the processor.
Added a few small details, and got this.
