- elnerdo, on 10/12/2007, -1/+14I wish I knew how many cubic-feet of air per minute an ordinary fan moved. Without that information, that number is completely useless to me.
- TokenUser, on 10/12/2007, -1/+8Wow ...
A link to engadget.com ...
Which links to hackaday.com ...
Which links the source at http://inventgeek.com/Projects/IonCooler/Overview.aspx
Thats one way for the folk at Weblogs to reap the rewards of advertising, and throwing a crumb to their orphaned step child.. - spliznork, on 10/12/2007, -0/+7See the Slashdot discussion from yesterday http://hardware.slashdot.org/article.pl?sid=06/09/17/2134250
The consensus is that 325 CFM is ludicrous and must be a typo, since largish case fans move 50-80 CFM. At 325 CFM, the air moving should make audible noise. And that ozone oxides copper, so its bad for your motherboard. And so on... - ePlus, on 10/12/2007, -2/+70.0 dBA!

- zbeast, on 10/12/2007, -0/+4Who cares about smog? What the trouble is this thing makes ozone.
Ozone eats rubber, ozone eats some plastics.
Ozone is not healthy for you..
Driving your car around and making ozone is fine, it's out side.
Your computer is in your room with you.
Maybe if you stuck with of those catalytic converters they started sticking on those
over priced ionic breeze's things on this device it would make it safer. - piesforyou, on 10/12/2007, -1/+4I agree, blogspam. Even if it is ENGADGET, it's still a BLOG which offers absolutely no more INFORMATION than the actual SOURCE. Link to the source, not a blog!!
- emperortomato, on 10/12/2007, -1/+4If it's anything like the ionic breeze you'll also be slowly killing yourself when you're around it.
- LoungeActx, on 10/12/2007, -1/+3Yeah, but these Ionic Breezes are also bad for your health. If you read the warning label on the box it says "Use in well ventillated room." You wanna know why? Because they release Ozone which causes cancer. Plus, using these things in a well ventillated room kinda defeats the purpose right?
From Consumer Reports:
Sharper Image’s Ionic Breeze Quadra Silent Air Purifier and four other similar machines fail to significantly clean the air — but also release potentially unhealthy levels of ozone.
The article is being published two months after San Francisco-based Sharper Image agreed to pay the magazine’s publisher, Consumers Union, $525,000 in legal costs after a judge dismissed its libel suit. The failed lawsuit alleged that earlier magazine articles highly critical of the Ionic Breeze’s ability to reduce airborne particles were false and malicious. - inactive, on 10/12/2007, -0/+2"total project cost: 160$ - 800$"
... That's an awfully large range there... - zip22, on 10/12/2007, -0/+2just some info on indor ozone
"Consumers Union believes that the CPSC should set indoor ozone limits for all air cleaners and mandate performance tests and labels disclosing the results. CU also believes that the Federal Trade Commission should take a close look at air-cleaner ads to determine whether they include unsubstantiated and deceptive claims.
In the meantime, we recommend avoiding ionizers that performed poorly or emitted significant ozone in our tests. “We can't guarantee safety at any ozone level, so it makes sense not to contaminate your living space,” says Jonathan Samet, M.D., chairman of the epidemiology department of the Johns Hopkins Bloomberg School of Public Health."

That is the REAL article link. - Broelke4, on 10/12/2007, -0/+2Dugg because thats my computer case.
But I think I'll just stick with my 4 casefans. - MYarms, on 10/12/2007, -0/+2I'm curious to know how well it actually works. They seem to have left that part out of the article.
- compu486, on 10/12/2007, -1/+3There are alot of applications where silent computers are tremendiously valuable. Audio mixing for instance.
- compu486, on 10/12/2007, -0/+1Its not being used to purify the air. If you read the article you would see they removed the diode that created all the ions and ozone. The ozone production from this is negligible at best. I realize everyone here is an expert... but do some research before sharing your opinion as fact. Simply put there are several patents on this topic. Ion fans emit no more ozone than a brush type fans motor arc. Also there are several no ozone producing versions of this system uses a tear drop shaped grounding rod. This is all in patent searches... this is a viable solution that no one has ever done. And he states it’s a prototype flat out in it. Be grateful people out there are tiring to make the world around us better via innovation!
- compu486, on 10/12/2007, -0/+1Are you including the computer components or not? if you have the gear its cheeper. if not you pay more. duh....
- mymoustache, on 10/12/2007, -0/+1I agree, there's a lot of talk about heat dissipation followed by absolutely no temperature data off the completed project.
It looks cool, but RadientBeing is right, we should see some kind of temperature data since that's at least partially the point of the the project.
@Smokester - that page 11 info just air volume and noise (i think)
/correct me if i'm wrong
//like i have to ask diggers to correct me... - RadiantBeing, on 10/12/2007, -1/+2The original report doesn't include any temperature readings either. At the very least they should have taken CPU temperature idling and under load.
- inactive, on 10/12/2007, -0/+1I don't know what he's including but I would assume that since they bought the equipment for their own project they would know how much it costs. That can't even be an estimate of what they spent with that much gap.
- pype, on 10/12/2007, -2/+3Meh - call me when it's the ONion cooled PC.
- Sonic84, on 10/12/2007, -1/+2I have one of those ionic air purifiers, a side effect is the air smells funny after a while. but it really does move a lot of air with near no noise.
- veruus, on 10/12/2007, -0/+1Seriously, this is about the 8th time this technology has been in a Digg post. WTF
- fatnutz, on 10/12/2007, -0/+1According to the actual article he's going to get temps up soon maybe tonight yet.
- elnerdo, on 10/12/2007, -1/+2You're awfully negative. This thing produces about 1/1000th the smog as your car does. I'm willing to bet that you still drive your car around.
- inactive, on 10/12/2007, -0/+1That info is there
http://inventgeek.com/Projects/IonCooler/Page11.aspx - LoungeActx, on 10/12/2007, -1/+2These things are soooo bad, not only are they piss poor at purifying the air they are known to cause cancer:

- tektalk, on 10/12/2007, -0/+0i only saw the pros but not the cons. its a grand, health risks, and something can go wrong.
- compu486, on 10/12/2007, -1/+1This is a amazing project.
They have a comparison of CFM of other fans on there last page. You can find the project directly at: http://www.Inventgeek.com/projects/ioncooler/overview.aspx
Looks like there forums are down, but they always do updates to the project and I already emailed them and got a yes to fix the omission for everyone. - IonFreak, on 10/12/2007, -2/+2Seriously! Do some research! There are tons of papers that show that the ozone level in your house with one of these things running is less than the air outside. Cars are the number one producer of ozone production. Not ionic air filters. There is a small percentage of people that have an intolerance to ozone. And asthmatics fall in that group mostly also.
- IonFreak, on 10/12/2007, -1/+1spliznork thats just not true!
The thing is 3 120 MM case fans tall. Using 3 high volume case fans you can do way more than there estimate. Also the unit is rated at 400 CFM so it’s entirely plausible it’s accurate. And that volume of air wont sound like a jet if its dispersed over the entire length of the cooler. It will deteriorate over time until you bust out your can o' air. - heyitsme23, on 10/12/2007, -0/+0lol that would be awsume, although I don't like onions. Maybe use the ironic air purifier instead of the ionic purifier.
- Bamborzled, on 10/12/2007, -1/+1Really? Just click on the picture, and you'll go to http://inventgeek.com/Projects/IonCooler/Overview.aspx
.
But of course, that's not obvious, and you should still link to the source. - compu486, on 10/12/2007, -1/+0They have a comparison of CFM of other fans on there last page. You can find the project directly at: http://www.Inventgeek.com/projects/ioncooler/page11.aspx
- IonFreak, on 10/12/2007, -1/+0Just google it or wiki it. its not complex. they dident need to explane how it works.
- Sweetdelight, on 10/12/2007, -3/+2Great, a Super silent cool computer.
However at a huge cost to the environment is not worth it. In my opinion.
However, if you don't give a ***** of the enviroment, wan't to smog it up and ozone in the air, then go ahead and go through with this awesome mod. - fugazi48, on 10/12/2007, -3/+0seems a little over the top...basically not worth it if you want silence and coolness just go water cooling simple as that
fan cooling if fine for me, if you have enough air moving in and out of a case and decent quality fans that don't make too much noise you are absolutely fine
