The latest processor and motherboard models to hit the market run much cooler whether AMD or Intel. Intel's previous socket 478 and 775 processors are very hot compared to the latest Core 2 Duo on the market. As for AMD, heat was never really much of an issue until the faster cores starting topping out. Between the two latest cores from each maker on the market, processor thermal properties have dropped to new lows and with much gratitude. Thermal dissipation is always a concern when dealing with processors of any type especially when the frequencies start climbing in stock or overclocked systems. CoolIT Systems developed their first own liquid cooling system for the avid users who want a cooler, more silent system as well as those who use more extreme methods of draining every ounce of performance from their system.
