A desktop-replacement laptop using the Centrino 2 Platform, Intel's highest dual-core mobile CPU, the Penryn-based Core 2 Extreme X9100 to be precise, was overclocked to 4.00 GHz with help from aggressive cooling made by CoolIT and Intel's Extreme Tuning Utility. Seen in the first picture is the laptop seated on an unreleased notebook component cooler made by CoolIT. The cooler uses external thermoelectric couple (TEC) and air cooling to draw heat away from the laptop. Despite using overclocked settings using this cooler, the CPU reaches a scorching 50° C.
The cooler releases in January 2008 and will be priced around US $120. This feat was also helped by Intel's new Extreme Tuning Utility (Iron City). Intel's Dan Ragland used the software to overclock the laptop's CPU to over 4GHz, stably. He commented that the notebook-cooler added around 500MHz over and above what's achievable by using the laptop's cooling alone.
