Just a quick note. FCPGA refers to the flip chip packaging. That basically means that its inside out or upside down. The really hot part is much more easily cooled. A bit like if your heart was on top of your chest instead of inside. It might sound a little stupid, but if your heart was incredibly burning hot, and to survive you had to cool it down, thats what you'd have to do. Otherwise, if you dumped ice cubes on your chest it still wouldn't cool your heart enough, and either way your lungs would probably fry in the meantime. Why are we designed with our testicles on the outside? We're all too familiar with how painfully sensitive and pitifully easily injured they are. Sounds like a crazy idea, but none of us would be here today, otherwise. It's all about the heat dissipation. Pure and simple.
Gee, I really wish I hadn't gone there...
