I just found this news on Matbe today (translated in english). They're talking about new 180mm case fans! I'm wondering how quiet they are and mainly, how we're gonna put those inside a normal case!

that fan could kill a person

No way. It can't be very powerful, it doesn't even have a large centre hub. Plus it's plastic. There's lots of other fans, such as Deltas, and Cor-something Rotrons(the 172mm ones with the metal blades) which would be far better choices for attempting to kill people with.

I was really just joking. However, I did once get my finger in a 7000rpm delta and it quickly became a bloody mess all over.

Uh, well, in that case, I was joking too. So if anyone turns up decapitated by a delta fan, I had nothing to do with it.

wow, 180mm fans, i want one right now! just imagine that monster at 400rpm, pushing lots of air, it should be quiet at very low speeds.
i even know how to mount it on the side cover, to replace my 120mm aluminium Evercool: http://forums.silentpcreview.com/viewtopic.php?t=20515

Very low frequency too, but is that such a good thing?
Just think - no need for a CPU fan with one of these! (Or any kind of fan for that matter!)


And it should be able to kill a person, but I'd use the corners of the frame rather than having it spin...

At this rate I can see the entire side of your case becoming one big slow moving fan maybe 400mm! I can dream...

so how long until we see the "ceiling fan mod" popping up on the forums?

My first impression is that it might be going to far. I mean, what will this fan really do for you that a 120mm fan won't? It really would need to run 400rpm in order to be quiet. And will it really be blowing much more air than a 120mm fan at 700rpm? Will it be much more quiet? And the airflow will be even more spread out than a 120mm fan. So it won't provide any directed airflow.

Just some thoughts I had.

I think it might actually be very useful. It could serve as an intake/CPU/VGA fan. Maybe even a hard drive fan too, mount the hard drives in 5.25 bays and duct the air from the fan that misses the CPU and GPU to the drives.

I'm going to duct tape a box fan to the side of my case... and for overclocking, I'm going to add a leaf blower for intake. Anyone knows how to silence one of these suckers?

PS. Just kidding. Don't threaten to decapitate me with a Delta, please!

So how long before Zalman or Thermalright put a heatsink under one of these .
Just what I need in my Micro ATX case .

I'm suddenly reminded of that picture where someone used an industrial fan to cool of their entire case.

Seriously though, people are getting more and more weary of LARGE computers (I know I am). There was a time when fullish towers were much more popular, now most people stop at mid towers (other than stacker, v2000 etc). Other than that, this could be OK I guess, although it'll let correspondingly more noise out.

Instead of modding a ceiling fan to the back or side of a computer case, why not do it the other way around? Stick a motherboard right under the ceiling fan that is already in the middle of the room!

Or maybe you want to stick the motherboard above the ceiling fan. I have not thought through the "blow vs suck" arguments yet.

That really didn't make sense. What did people need those huge cases for back then? Airflow was hardly an issue, Most people didn't have CD-writers, and earlier, not even CD-rom drives, never mind fan controllers or display pannels. Not only were CD-drives expensive, but IDE would probably have been bottlenecked by two drives sharing a channel(correct me if I'm wrong), and hard drives were expensive too.

Maybe we'll see a turnaraund back to huge cases. Maybe wide ones, with DVD changers.

I dont really know (need is such an interesting word) but I remember it being the case in the enthusiast/OC crowds. It was right after people started shying away from desktop cases. Anyway, I think smaller PC's have a much better wife acceptance factor and the smaller cases can be used more than just in a home-office especially now with thin LCDs.

To fit stuff. Ever see a vesa local bus card? Expansion cards used to run the full length of the motherboard--and then some. Also, a 5.25" drive used to refer to a floppy disc, not a CD-ROM. And of course, there's a reason why "half-height" drives are called "half-height". Guess how high they used to be!

There was also a time when the serial and parallel ports that are now stuffed in an ATX mobo backplane often consumed expansion slot backplanes. And you also consumed expansion slots on a disc controller. Heck, you could consume an expansion slot on a MOUSE controller.

Computer stuff used to be just plain bulkier than today's stuff. I really don't see it going back to how it was before.

Check this picture out, its from a Finnish computer magazine, number 12 of year 1990.




Here´s a quick translation by me..

FOUR GIGABYTES!
If you need really large amounts of mass-storage or just want to own the largest hard-drive station on the block, the Storage Dimension four gigabyte is the solution. The price is 30.000$, but what would not pay to be the king of the hill?

would you please mind being on topic? we are discussing about 18cm fans, in case you forgot...

On topic discussion????? You must be new here.

4Gb mini-ipod £150...

Sometimes forget just how fast things change - gee I remember when it was 80mm fans or 80mm fans only but then I'm practically a fossil...

Oh yeah, I forgot my on topic comment earlier:

I can see potential usefulness for large diameter fans if it's the one fan in the system. You'd use multiple ducts from the fan to feed air separately to the PSU, CPU, GPU. By using multiple ducts, you get essentially the same effect as multiple smaller fans directly feeding fresh air separately to each component. However, there's potentially less noise and the airflow can theoretically be generated with less loss in turbulence.

Perfect size for a heater core, if they have any pressure.

That wasn't even that long ago, either; a computer I built 6 years ago filled 7 PCI slots with crap; the one I built last week had everything but the video built onto the motherboard this time around. It's a nice feeling to not have your case so stinking crowded.

I remember when it was no-fans-required (except maybe a milk bottle on top of the Speccy to prevent overheating). You need a Welcome to SPCR!

I think IsaacKuo has a great idea. Four 90mm ducts (approx...) would provide great spot cooling, and since the hottest components don't recycle their air it should mean even less noise. The only thing we need now is a case that will fit such a large fan...

I just found this case mod on 2CookTek... Ok, it's not a 180mm fan but a 170mm fan, and it's probably not so quiet... but that can give some ideas!

I believe the nickname for that was the 'waste disposal unit'...
