kony pravi: You might want to read up on the fact that 9600 baud on computers is no longer 9600 baud and not only in multitasking systems. It has to do with the point that all modern OS's CPU time scheduling mechanisms are incompetent. It's not like 9600 baud is something the hardware could not manage, it's the point that the software's triggers and events misfire by design. Yes, it could. The theory was tested and the result prooven. Read the "Sythesis OS" whitepaper for details. In short, it is possible to make an OS's CPU time scheduler automatically detect how much CPU time and when a generic program needs to process it's input signal at the actual data rate. Modern computers have more than enough CPU power to provide for all the needs simultaneously, it's all about the OS not doing things flexibly enough. If you want a good example of the catastrophic state that that CPU time scheduler in Windows is in, use a program that counts how much CPU time it gets, run only it and Windows, then wiggle your mouse around the Start button area and see the user program suddenly getting way more CPU time than before. -- Primary function: Coprocessor Secondary function: Cluster commander http://www.thought-beacon.net Pay once per lifetime webhosting: http://farcomm-it.com/?ref=jsah We are the paragon of humanity.

kony pravi: I second that. The packaging for fans usually comes with preprinted text in the following sequence: [ ] Fluid bearing [ ] Sleeve bearing [ ] Ball bearing ....the sequence is always used to indicate worst to best. Fluid bearings die soon, Sleeve bearings sometimes develop rattling, Ball bearings are the best choice. At work, I service very high quality high pressure pumps. They contain only the best everything and they use double ball bearings everywhere. -- Primary function: Coprocessor Secondary function: Cluster commander http://www.thought-beacon.net Pay once per lifetime webhosting: http://farcomm-it.com/?ref=jsah We are the paragon of humanity.

Hey Kony, since you seem to know so much about fans... what the hell is the deal with those chipset coolers that have flakey fans? Some of them spin at >7Krpm and last 6 months max. Is it even possible to make such small fans move enough air and still last? They're usually "buried frame" type and easily replaced but impossible to find, even from distributors. I've been able to find a 45mm diameter "bury-frame" fan for my GPU cooler at Directron but the 30mm versions usually used on chipset coolers are just not available anywhere. Do you know why? Any ideas on where I might find a "quality" version?... or do the mfrs prefer to sell with a hunk of metal for the extra $$?
It seems you're suggesting computers don't work at all, since they can and do processes 9600 baud signals as well as a myrid # of others, given I/O peripherals. You're out of your mind. On the one hand you discount the hardware itself, then turn around and cite OS. It seems you are on a quest for a solution without a problem. "All the needs"? You lack a very basic understanding of the situation. No OS change makes a CPU, bus, etc, etc, faster than technically possible. When the needs exceed the bandwidth, processing ability, etc, there's no OS change that will matter. Trying to tweak things to get a few percent improvement would always be a minimal improvement realative to the generational hardware gains. That's supposed to happen, not a catastrophe but correct function. You don't WANT something you're NOT doing to take as much time as something you actively ARE doing, ELSE there is a provision for that, the higher priority assignment.
In other words, you cannot provide a citation. http://www.newegg.com/Product/Product.asp?Item=N82E16835185006 Sony fluid dynamic bearing 120 mm case fan. Has a 15,000 our lifespan. http://www.newegg.com/Product/Product.asp?Item=N82E16835186008 Arctic Cooling fluid dynamic bearing 120 mm case fan. Comes with a six-year warranty. Panasonic is a major manufacturer of fluid dynamic bearing fans, for many years. More like teaching you a lesson. I won't hold my breath waiting for citations you will never provide.
I guess this troll also considers "sleeve bearing" to be a marketing term.

That makes two trolls with no citations. Is that supposed to be a citation? If you're so sure of yourself, provide a citation. The best hard drives use fluid dynamic bearings.
In other words, it is common knowledge and you can easily find this yourself via: Google or any mainstream search service Usenet search Any fan manufacturer that makes lifespan projections There are NO fan manufacturers that claim fluid bearing fans have longer lifespan and most claim only (roughly) 50% of the lifespan of dual ball bearings. Which citation would you prefer? There are SO many, so let's get your foolish arguments out of the way first so I can provide the most applicable to dispell your misunderstanding. 15,000 hour? While that IS what the product page says, it's funny! The funny part is you are clueless about fans. If you'd had a clue, you would have realized that 15,000 hours is an incredibly LOW lifespan for a fan, that the lifespan projection for that product was supposed to be 150,000 hours. They can make this questionable lifespan rating because of two factors: 1) Assume ideal operating condition. IE- low heat 2) They base it on the low RPM. Usually fan manufacturers spec a family of fans, including those with much higher RPM, while the higher RPM fans have a lower actual lifespan than the lower RPM of the same model. Similarly, any crap fan can be taken out of context, selectively focusing on the lowest RPM model and then suggesting a longer lifespan than it actually has. That doesn't mean it has a longer lifespan, it means they've overpriced it enough to offset any potential RMA issues. Do you realize just how little a sleeve fan costs in volume? It is trivial to them to replace it free, the shipping cost is multiple times as much, but putting interest on their profit, they can cover that too. Further, six years is lower than the expected lifespan of a system. Yes, I'd already mentioned them as an exception. They do NOT rate their fluid dynamic bearing fans as having a higher lifespan than their dual ball bearing fans. BTW, do us all a favor and stop with the nonsense about "fluid dynamic bearings", as they are SLEEVE BEARINGS and any other term is a senseless marketing gimmick. You have enough ego to get your system's cooling into a bind but nowhere near enough experience to teach. Don't you mean that you're just ignorant? Seriously, you started a disagreement about fans yet you think we need to provide a spec when you could have easily read it yourself from any of the major manufacturers if you had ever been to their websites and read the datasheets. If it were new information, it'd be "news", but the only thing new is that we became aware how ignorant you are about fans. Anyone and their brother has known dual ball bearing fans are at least as long lived, sometimes MUCH longer lived. These products you cite haven't even existed long enough for you to pretend to have any experience with their actual lifespans. It is impossible for you to have experience with them, whether their projections actually hold true. So you're an armchair quarterback who read marketing blurbs, believed them, and didn't ever bother to test anything yourself.
We aren't burdened with countering anyone's ignorance, it would never end. This is another example of common knowledge, that which any competent engineer or system integrator has know since the beginning and believe me, they'd love to shave some $ off the costs if there weren't the detractions, especially when sleeve bearing fans have significantly lower high pitched noise. So you can't be bothered to find any information yourself, only a product listing? Do you believe all product listings? How about a $15 600W PSU with one of those fluid dynamic blahblahblah in it, are those good too because they wrote some lofty specs? Sorry, there comes a point where you have to have some experience instead of just repeating marketing by gypsy companies selling PC parts they dont' even make. What might we Google for a citation? How about; http://www.google.com/search?hl=en&q=ball+bearings+sleeve+bearings VERY FIRST GOOGLE HIT, http://www.currentsolutions.com/knowledge/ballbearingvssleevefans.htm excerpt: "The chart indicates that when temperatures ranged from 25 to 60 degrees C, ball-bearing fans on average outlasted sleeve-bearing fans by 50 percent. When temperatures exceeded 700 degrees C, ball-bearing fans ran for 45,000 hours, while sleeve-bearing fans became inoperable. Yet, when the ambient temperatures were relatively low, sleeve-bearing fans lasted as long as ball-bearing fans." Since any normal system will be in that 25-60C range, we can conclude this is one citation. SECOND HIT, http://www.frostytech.com/articleview.cfm?articleID=193 excerpts; "Ball bearings... most important for our situation - long life" "With proper lubrication sleeve bearings will provide performance and service on par with that of their ball bearing counterparts. If left alone for a long time, and run at higher temperatures they will fail before the ball bearings will." ------------------ So far we have the first two hits Google found. The trend continues with practically EVERY link that discusses both types. So it seems it is [entire world] vs [you] So tell us, is it you [the one who doesn't make fans, hasn't actually tested the fans you linked for they haven't even existed as long as their spec'd lifespan, and doesn't even use proper terms for sleeve bearing fans] that knows about fans, or it is major website reviewers, fan manufacturers themselves, engineers, and just about every possible 3rd party? Sorry but you are a lone advocate of them for lifespan improvement and have no evidence besides a line of text versus 'site after 'site after 'site.

This is another example of common knowledge, that which any competent engineer or system integrator has know since the beginning and believe me, they'd love to shave some $ off the costs if there weren't the detractions, especially when sleeve bearing fans have significantly lower high pitched noise. So you can't be bothered to find any information yourself, only a product listing? Do you believe all product listings? How about a $15 600W PSU with one of those fluid dynamic blahblahblah in it, are those good too because they wrote some lofty specs? Sorry, there comes a point where you have to have some experience instead of just repeating marketing by gypsy companies selling PC parts they dont' even make. What might we Google for a citation? How about; http://www.google.com/search?hl=en&q=ball+bearings+sleeve+bearings VERY FIRST GOOGLE HIT, http://www.currentsolutions.com/knowledge/ballbearingvssleevefans.htm excerpt: "The chart indicates that when temperatures ranged from 25 to 60 degrees C, ball-bearing fans on average outlasted sleeve-bearing fans by 50 percent. When temperatures exceeded 700 degrees C, ball-bearing fans ran for 45,000 hours, while sleeve-bearing fans became inoperable. Yet, when the ambient temperatures were relatively low, sleeve-bearing fans lasted as long as ball-bearing fans." Since any normal system will be in that 25-60C range, we can conclude this is one citation. SECOND HIT, http://www.frostytech.com/articleview.cfm?articleID=193 excerpts; "Ball bearings... most important for our situation - long life" "With proper lubrication sleeve bearings will provide performance and service on par with that of their ball bearing counterparts. If left alone for a long time, and run at higher temperatures they will fail before the ball bearings will." ------------------ So far we have the first two hits Google found. The trend continues with practically EVERY link that discusses both types. So it seems it is [entire world] vs [you] So tell us, is it you [the one who doesn't make fans, hasn't actually tested the fans you linked for they haven't even existed as long as their spec'd lifespan, and doesn't even use proper terms for sleeve bearing fans] that knows about fans, or it is major website reviewers, fan manufacturers themselves, engineers, and just about every possible 3rd party? Sorry but you are a lone advocate of them for lifespan improvement and have no evidence besides a line of text versus 'site after 'site after 'site.
