Chip cooling: The answer is blowing in the wind

Researchers at Purdue University have made a major breakthrough by managing to achieve better chip cooling through the use of 'ionic wind'. Funded by Intel the promising new solution more than doubles the air-based heat removal solutions seen in laptops and other small appliances today, paving the way for faster and more powerful consumer products. According to the source article, we may see this technology debut as early as 2010.

Called “Ionic Wind,” this new solution addresses one of the biggest bottlenecks in forced air heat removal technologies: The “no-slip effect”, which refers to a scenario in which air molecules near the surface of a metal are nearly stationary, making them difficult to blow away. The further out the molecules are from the surface, the more easily they move about. While this allows those more distant molecules to be blown, the ones closer to the metal act as insulators keeping the heat inside.

Purdue's new technique breaks down that insulation barrier and creates thousands of tiny hurricanes. Once the hurricanes begin moving air around, the heat can be blown away.

This hurricane effect is achieved by using a combination of anodes and cathodes arranged in a particular way and spaced about 10 mm apart. When a voltage is applied, ion jets are created and ejected from the nodes. When this happens, the normally stationary surface air begins to move in tiny vortexes. Once pulled away from the surface by the vortex, cooler air is brought in behind to fill in the void. The metal gives off its heat to the cooler air which is then, in turn, also ejected by another vortex. This effect yields the greater heat exchange efficiency seen in this solution.

In laboratory simulations scientists have seen a reduction in cpu heat from 60 degrees Celsius to 35 degrees Celsius. Further, according to the research team spokesperson, the technology in its current state is very fragile but should reach a consumer level within a year.

I found this anti virus software aimed at gamers and installed the demo (free for 2 months).

I had Macafee 8.1 which is a bit old and have been looking for some new anti virus. The anti virus is powered by Bullguard and the firewall is powered by sygate. The software detects when a games launched and switches into low resource mode and opens the ports for that game. It seems good while in game (CSS), although it has slowed down my pc slightly while not in game which I dont mind. You can configure all the gaming profiles and even add your own.

Has anyone else got this software and what are your opinions?

Use NOD32 mate, doesn't take up enough resource for you to notice in the first place

AVG with daily scans, along with adaware and spybot, and Xp Firewall.

Suits me and does job.

I dont even use a anti virus anymore, used NOD32 for years without getting a virus so thought whats the point.

Touch wood I havent had anything yet.

It doesn't look too bad, takes up 30+mb of memory tho :(

I use AntiVir as it's free and seems to work quite well. Also updates itself every day and doesn't take up much memory.

I switched to it after noticing f-secure was using a lot of resources and also after doing some research and finding it came 3rd in a test on :) and the top 2 were expensive corporate suites

They used to give BullGuard with Kazaa. Thats good enough for me to NEVER want to use it.

Im quite happy with Avast.

Can`t argue with that at all.

2nd point, look at less pron on the net.

3rdly Bullguard ?!?!?!?!?!??! Got this vision of playing a game, then suddenly an advert for poker pops up or something >.<
