CPU cooling system debuts

Active Cool on Monday is launching its AC4G CPU cooling system, a thermo-electric apparatus designed to address the processor heat "crisis," according to the company.

As PC processors get smaller and faster, heat remains a challenge to system reliability, Active Cool said. The company claims its system, based on a solid-state thermo-electric heat pump, can cool the most advanced Intel Pentium 4 processors and AMD K8 processors. The ACG4 pumps heat out of the processor and dynamically reduces fan noise through use of a noiseless electronic heat pump.

Active Cool's system, which occupies a PCI slot, features microprocessor-controlled thermo-electric cooling, maintenance of PC temperatures at 26 Centigrade during normal operation, and independent operation from the PC.

The technology is based on thermo-electric components used in aerospace and military applications, said Ronen Meir, founder and president of the Ashkelon, Israel-based company. The technology can cool chips with speeds of as much as 4GHz, he said.

Initially, Active Cool intends to sell its technology through conventional cooling system manufacturers. In about a year, the company will approach PC manufacturers to either sell or license it to them, Meir said.

Hewlett-Packard this summer announced that it, too, is working on system-cooling technologies, applying its inkjet printer device to dispense dielectric fluid to cool chips.

It’s perfect for mobile workers. Just take it out — it’s small enough to sit anywhere — turn it on, load a sheet of paper, and start printing.
