I guess more fans doesn't mean better.
VERY TRUE!! But keep in mind there are more components than just the CPU. You may notice your GPU, Northbridge or southbridge get lower temps with the side fan. I observed the northbridge in my comp to lower in temperature while my GPU and CPU gained a few degrees with a side fan. However, the best overall setup for me seems to be front to back with NO side fan and the GPU placed away from the Northbridge.
