PC Case Made Completely of Fans
drgroove writes "I work in a computer store building PCs all day. With every new case there are one or two 8cm case fans included. Most of the systems we build do not need any more cooling than is supplied by the CPU fan as most of our customers generally don't go in for all this 'overclocking malarky.'
Looking around the stock room I discovered two large boxes of unused 8cm case fans. Surfing through case mod sites, the most popular mod you see (besides Lexan windows) is some form of whizzy cooling device, be it fan or waterblock. People go to great lengths to keep their PCs cool. Now... putting these two things together..."
How LOUD does that thing have to be? There are two fans in my case. One has been disabled due to the incessant racket. I can't imagine what this thing is like.
'Standards' in computing only impress those who are impressed by things like 'standards'.

Anyways, it's a New Zealand mod. Which doesn't use Number 8 wire.
For shame.
But that is only 18 fans, which is WAY different from 70!!
While I and probably every other PC user on earth are trying to reduce power usage and noise, this guy go the exact opposite. Weird. But, it's probably the perfect case for a dual intel p4. ;-)
"Only two things are infinite, the universe and human stupidity, and I'm not sure about the former" - Albert Einstein.
He claims "Looking from the front of the case, air flows in through the left side and out the right side. The front an back blow air into the case and air flows from the top of the case down and out the bottom... theoretically anyway."
Ideally, the top/bottom flow direction should be from bottom to top, since the coldest air is on the floor of your room (heat rises). Most datacenter-class stuff goes bottom to top as well, but that's just because that's where the A/C is, underneath the servers in the raised flooring.
And having two major airflows intersecting in the case (left->right vs top->bottom) seems inefficient as well.
Personally, I would have set it up with the bottom, front, and back as intakes, and the top and both sides as outflows. Only issue there is the usual power-supply placement puts it outflowing on the back, but I guess in such a custom case you could move the power supply so that the "rear" of it is blowing out one of the sides or the top.

It's because the moderators here suck.
Nah, the posts just blow.
But yours wasn't on slashdot.

holy crap. the asshole removes the case fans and just leaves the cpu fan and psu fan in?
ALL the DEAD systems that have come in here, have had failed OR missing fans
[me:] You should probably post a comment about that.
meh
god. how fucking stupid to remove the fucking case fans
the cpu fan and psu fan just aren't enough
and when one of them fails. kiss your computer goodbuy
bye
that's one of the reasons i hate dell so much
they typically have an 80 mm fan on the outside.
and have a cowl that goes around the cpu heatsink
with no fan on the cpu
if the fan fails. it overheats badly
need..
at least ONE fan on the case
one psu fan
one cpu fan
if anything should fail. it won't destroy the hd and ram
god. they can't spend the 3 fucking bucks on a fan
oh hell they just remove em and dump em.
Not "Funny", but "Insightful".
Now that's funny.
If you don't like the story, don't read it. I avoid Slashdot like the plague on 1. april, but I don't complain about it. Well, not much anyway.
Which is probably his problem. Unlike light, streams of air can not cross each other. If he has two air streams at 90 degrees intersecting he will get all sorts of turbulence swirling around inside his case. If he turned off the fans at top and bottom, and front and back, then he would get air flowing right through the case, which would probably be more efficient (discounting eddies from irregular shaped components.
Oh, he should also probably replace his CPU fan with a relatively large passive cooler.
