well im looking into building a new build for vista and so far i have 6 fans in my new build... 5 vantec 80 mm fans and a 120 mm silverstone fane on the heatsink...now i was thinking about modding my case and putting a couple vent fans at the top but is there a point to where there are too many fans in your case

More about : fans

you have to many when you run out of places to plug them in. and then you just get some kind of crazy adapter so you can have more, so basiclly you can never haven enough fans, or about 120, all of them have to have led's though, because its cool.

I saw a pic somewhere of a case virtually MADE out of fans. It was like a shell with something like 30+ fans held together with cable ties :lol:  .

i know the exact pc your talking about, i cant find any good pics online though.

heres the best one i could find.

Too much is when you have to add more fans to cool the other fans you have already added or when your case begins to lift off and levitate:lol:

Why stop at cold beer?

If you can stand the extra noise, then you may as well put them in. It certainly won't hurt to have a couple more exhaust fans.

Wow! That case took a nose dive of the ugly tree and hit every branch on the way down.

or just go phase chang. on everything, gfx card, cpu, northbridge, southbridge (why, i have no idea), sound card, hdd, psu, ram, cd/dvd drive, even the motors on the fans in your case. it would be insanly expensive and complicated, other then that you would have a really cool pc!
December 3, 2006 2:59:59 AM

Yeah, but look how much you can overclock it!!!
December 3, 2006 3:01:37 AM

ROFL Phase change on your sound card chip. 8O

Somewhere in some CAD file, the design is alive and well, and someone is getting paid for it.

Just put it in a freezer with dry ice......cuz you know......since it's "dry", you won't need to worry about "wet" condensation or electrical problems ;)

Thanks! Was just getting around to that, but was too busy laughing! That's definately original... a PVC rig with the prop from a Cessna!

i already gotcha beat man....
4 case fans (2x120mm and 2x90mm)
Corsair RAM cooling fans (3x40mm)
Vantec PCI fan card (2x70mm)
CPU cooling fan (1x92mm)
That makes 10, not including built-in fans for Graphics card and PSU...

It's not about how many fans you got but how well you control the velocity and direction of air-flow thru the case....in thru the lower front and out thru the upper back while flowing across the major components including the hard-drives, chipset heat-sinks, graphics card, CPU and RAM.

Good bye.... power supply stability.

Fans use a bit of juice dude, don't go overboard.

1 or 2 PSU
1 or 2 Exhaust / Intake
1 CPU
1 GPU (maybe two in some designs ?)
1 NorthBridge

Any more than that is overkill.

Just get a well ventilated case, with a 'grill' over the CPU and Video card(s).

how about this. 4, 120 mm thermaltake thunderblades on the side of my case, 1 120mm thunderblade in the front, 2 thunderblades as exhaust, one 80mm top exhaust, and one aerocool xtreme turbine on the heatsink

7 thunderblades * 78 cfm per fan = 549 cfm
1 80mm fan = 32.5 cfm
1 xtreme turbine = 89.39 cfm

so thats 9 total fans, pushing 667.89 cfm through my case. ;p

if you don't believe me, ill send you pictures

True, but fans can be variable in speed and draw, esp while revving up, other components don't like minor fluctuations.

I know at least two people who have caused more problems in their PCs by adding more fans, issues they associated incorrectly to heat, so they added more fans..... (the cycle continues until their PC suffered some minor issues).

A mainboard was damaged enough in-so-far that it became useless.

There is likely some technical / electrical engineering explanation, I just follow the ATX / FormFactor specifications and avoid systems that don't follow them.

(Sadly many cases do not comply with the ATX / FormFactor specs considering what hardware is being put into them).

The nice thing about having so many fans in a computer is that when you are gaming, you dont have to have a heater in the room.

You ask the wrong question Grasshopper.

Much happier will you be when building a box using the fewest fans possible. Less is more, and least is best.

Believe me when I tell you that you will not fall in love with a case full of howling fans. It will, over a period of time, drive you stark-staring mad.

Eventually, appreciate quietness you will.

Nice, if not for the fact dust bunnies will hold secret or.. NOT SO SECRET meetings everywhere in and outside the case. And if the fan starts chopping up any of the cables and shorting them through it's metallic blades, you'll get a neat dust BOMB! :p

Has anyone ever seen those foot long radial fans they use with gas fireplaces?

I've been meaning to install one somewhere in my case (I managed to get ~11 of these, don't know what else I'm going to use them in other than 2 in an aquarium for cooling the MH lamps.), but haven't gotten around to drilling and cutting for the intake of the fan yet.

Those things push a lot of air, I don't have an exact number, but they're powerful enough to push your hand away at ~1.5m. They do pull quite a bit of power tho, ~65w.

I would absolutely love to see someone have a few of those fans in their case, and all set to full speed. :twisted:

yea im thinking about totally doing an overhaul on the chenming case that im gettings so im thinking about 3 in the front, 2-3 on top, one in the window, and two in the back...

You can get all that at Home Depot. Now that it's holiday you might get it cheaper. Components are PVC pipes 1 1/4" diameter, PVC elbows, adhesive or sealer, that metal strips with screw holes, and one industrial fan of your choice.

What do you use for your filter?

a couple layers of chicken wire and stretched out steel wool in between for good measure.

That would work. I was thinking about AC/swamp cooler matting.
