First off..... What is this? Did everyone get Friday afternoon off? Oh, ok, you guys in the east are 3 hours ahead. Rockr, did you get the afternoon off?

You said it Brother!!

To me a fan is a fan and like everything else mechanical in nature they are prone to fail whenever they damn well feel like.
Again, you said it Brother! Said it well too!
The whole point of a sleeve bearing in a fan is it's inexpensive
. There's more than just riding on metal to metal, plastic to plastic, or lubrication....If
there is lubrication. They're inexpensive, buy 3 so you have replacements!
BTW, if you look at my sig line, I have 4, soon to be 6, Zalman fans for sale.

When the sleeve is in a horizontal position the lubricant can easily cover the entire shaft (even if it pooled in the bottom the shaft would all be lubricated as it spun through). When the shaft is vertical, the lubricant might settle towards the bottom and not coat the whole shaft no matter how hard it spins. This would lead to metal on metal contact wearing the bearing and making noise.
That being said most sleeve bearing are made out of a self-lubricating metal such as brass so the effects aren't immediate. That's why you can have a sleeve bearing in the vertical position and not have the fan instantly seize up. Also, I am not taking into effect capillary action where if the gap between the shaft and bearing is low enough the lubricant can pull itself up.
I dunno, it always seems like lubricating vertical axes is a bit hard and we usually switch to ball-bearings for the verticals at school.
But yeah, mechanical things do fail whenever they damn well please
You're starting to answer things the way I do! LOL! You left out the part that since it's a fan, if it's oriented the right way there could also be a little cushion of air that helps keep it from wearing out. I'm one of the first people to jump up & attest to things wearing out......
"Don't worry, your pump will last 5 to 10 years, they never fail in short periods of time. They have ceramic bearings in them, they're fantastic, plus when they're on there's a kind of magnetic levitation in the works too."
Uh huh, that's why my system locked up at 100c and I burned the side of my hand on the cpu fitting when I was checking for loose wires. My pump was just over 90 days, which I've always heard is the prime point for failure if it's electronically controlled.

Yep, mine's in AHCI too. In fact, I had it set for RAID 0 for about 20 days when I seperated them. I just moved to to the other onboard controller so it couldn't see the second SSD. In fact, it still doesn't show in some programs, but it's there in Win7!

mr-Charles . . .
Just change it, it won't affect it.
He writes more "consise" then you and I do. A gift to him and our readers but it might put us out of business Boss.
I told Chris it was a combination of Engineering school & PLDC that ruined me, before that I could say things in a sentence. You know
how it is now! LOL!!

Ok, trying to follow Rockrs act I want to say: Sleeve bearing, make a ring with your thumb & forefinger & put a finger from your other hand in it. Rifle bearing, now put a lubricated gear shaped disc around the finger you inserted.
Engineering again, it's not that easy.
Sleeve bearing, aka, one type of plain bearing: http://e-drexler.com/p/04/03/0323bearingDesigns.html
The Military uses Drexler, well, they did when me & Enigma were in, that's where I went first. I love atomic models!
Hee hee: Atomic Model - She looks fantastic, just don't be around when she goes off!
Look at the Wiki for plain bearing: http://en.wikipedia.org/wiki/Bearing_(mechanical
Rifle bearing, sure its the same, with a twist. As I've said before, sometimes the best answers are on our forums: http://www.overclock.net/air-cooling...ml#post9820550
This type is getting harder to find as there isn't much gain for the cost increase.
On of the best I've seen in long time is CM's Excalibur, not long term tests yet but I'd like to see how long they last, scroll down to the drawing: http://www.coolermaster.com/product.php?product_id=6634

Question to the Scouts?
Can the computer tell when there is a SSD and not a Mechanical HDD in the Build?
My wife just told my dog to eat his food. There are starving Dogs in China.
Well, it depends!
Does the system know it's mechanical or SS? SS being solid state. Not really, it's a segmented memory block, the hardware can't tell the difference. Yet.
Does it handle it differently? Not if you set it up right, it's the software that knows the difference & treats it differently by using the TRIM command or not defragging. BTW, if you haven't set it to NOT defrag, Win7 has probably been defragging your SSD once a week. In hardware, if you set your PCI above 100%, your HDD may run a bit faster, probably up to 105%, above that it may fry the controller. On an SSD, set it above 100% and it probably wont even be recognized.
Then again, with the new EFI bios, a GUI bios, things will change a whole lot! It may be able to tell when you have an SSD and to set it up without all the junk on it..... if they program the bios right.
Edit before post:
Just read what PapaSmurf put up & yeah, forgot that part, if you don't turn AHCI on before installing Windows, then it probably won't turn on, but if you did it first, you can go back & forth in the bios, usually with no problem (there's always exceptions), one thing though, in Device Manager it will always say it's an AHCI controlled computer, even if it's turned off. Also what he said about the intel & jmicron controllers is true for me too, but I have "The Book" if you AMD guys want me to check it??Edited by BriSleep - 10/8/10 at 4:50pm
