When I opened the box of my Creative TNT2 Ultra (it has 5ns SEC memory), the first thing I noticed was the puny heatsink and fan. Besides that I also noticed that it was poorly glued to the core-processor, this could not be good for overclocking. I knew I could do a lot better then Creative.

As I was working as a Development Engineer at the moment, I had the opportunity and materials to waste some of the companies money. So I took a piece of copper (50x50x15 mm) and created a heatsink from it with 13x13 rows of 2x2x10 mm blades. It took me only about 6 hours ;-) to complete it.

I glued it to the core-processor and attached a 40x40 mm fan to it. I must say I never ran the TNT2 with the original heatsink on it, so I can't really say if it's able to run any faster now. But it sure looks cool and I am able to run it rock-solid at 170 MHz core and 220 MHz memory.

BTW: in the pictures the TNT2 is lying on my desk. Some of you might recognize that it is made from carbon fibre reinforced PEI (PolyEtherImide) which is a material we used at Fokker Special Products to make airplane (Airbus and Apache) and rocket (Ariane 5) parts.

I made a sandwich off 2 layers of carbon fibre-PEI and a 2 cm thick light core material. It was made out of  waste material, rests on only 3 legs (on at each end), spans 3.5 meters  with a 135 deg bend in the middle and is 80 cm deep. Because of the stiffness of the sandwich fibre reinforced PEI, I am able to sit in the middle of the desk, while it will only bend about 5 mm.
