You guys i believe this is true because the heat is caused by the number of transistors and even tough cpu's get smaller they olso get faster with more transistors and produce more heat.

smaller transistors leak more but also have a shorter period of time to change state thus making them more efficient.

The heat is caused by everything. Size, speed, insulating layers.... Research the AMD Thoroughbred A vs. B core for a few examples, others can be found with various revisions of the P4 core and recent revisions of Core 2 Duo/Quad cpu's (including Penryn most importantly).

why did you even make a thread of your beliefs? do you have any articles to back up your opinion or is this gonna turn into the same as the wireless thread

True, but the new chips are made with materials different than silicon dioxide which leak less when shrunk. (This improves reliability as well)
