... if you don't get electricuted or leave the computer unpowered overnight. I think a flash HD might have been a better idea.Originally Posted by charleski
I dont really understand how this works? what generates the airflow?
It obviously requires some care in the fabrication, but once completed and properly shielded it's as safe as any ionic air cleaner. Probably important to make sure that any large pieces of metal in the airflow path are correctly grounded, as he points out in the conclusion.
It works because the electrons leap across the space between the cathode and anode. In doing so, they slam into air molecules with quite a high velocity and these ions then transmit their momentum to other neighbouring molecules. Here's a news article about an attempt to use the same principle directly on chip coolers.
Its looks brilliant but the thing is, there a no temperatures, no benchmarks and no overclocking results from it.
If it does work that well i would have thought that he would have shown some temps at least.
May give it a try when i have the time and the money to do it.
I'd of like to seen temps too and exactly how he figured out it was 325CFM.
I have the case he used and the sheer size of it keeps many things cool. I can run mine with all the fans off when idle.
That ionic thing would only need to generate a modest amount of airflow for the system to run without fans.
He needs to get with the times !The main reason we chose the Intel CPU is if for some reason there was a thermal issue it will self-protect the CPU unlike AMD's.
Every motherboard I've used in the last few years has a BIOS option for it anyway, so CPU choice is unimportant. Not to mention the only reason Intel had it was because of their 150W monsters.
That sounds fairly impossible. The only thing it could do is ionise molecules in the air and then use something to attract the ionised particles.
You can't shoot electrons at air molecules and expect wind. At least from what I've read/learned.
It's not, it's the way it works.
Electrons have momentum and they transfer that to the ions. What, do you think the momentum would just go away when an electron ionises an air molecule?
...
I know the theory works, dont know if it could push 325cfm, anyone who has played with high airflow fans (200+) will know how much air that is and even without moving parts it wont be silent, because of the turbulence.

I think 325 CFM is vastly overstated, more likely to be 32.5 CFM.
I have a 235 CFM fan and with it going even at half speed just the air flow noise is very noticable. If he was really blowing 325 CFM you'd be able to hear a fairly loud roar of air.
A 120mm fan running full speed can easily push out 80-90 cfm according to the specs. The surface area in his project is roughly the equivalent of the active area of 5 (did some calculations and it turned out I'd been too conservative) 120mm fans. So the figure actually seems reasonable if he's able to apply similar force to the air passing through. He should have mentioned where he got the figure though.
The problem with using really high cfm 120mm fans is that all that airflow is happening across a much smaller area, so causing much more turbulence.

You just contradicted yourself
?You just contradicted yourself
Moving a given volume of air through a wide pipe means it'll have to flow at a lower velocity than using a narrow pipe. Lower velocity = less turbulence.
Airflow for size is about the same. So the amount of air flowing through any given area is about the same as a high performance 120mm fan.
