fan size

ArrizX · 05-04-2005, 11:01 PM

i am thinking of getting a custom computer case, that has 2 fan slots that are 120 mm, now, is that too big of a fan, for do i only need one 120 mm fan.....please explain

Mental Liberator · 05-04-2005, 11:02 PM

There are 80mm and 120mm, 120 makes more sound but increases the air flow by more. I just have 2 80mm fans and i'm fine.

ArrizX · 05-04-2005, 11:06 PM

actually, i just looked, and i noticed taht it has room for one 90 mm fan, or to 120 mm fans......what about one 90 mm fan, is that good, or not enough

What are your system specs? Mine is on a pentium 4 3.0 ghz at like 65 c with only 2 80mm fans and is the most stable thing ever. So I'm pretty sure you would only need 2, 80mm or 120mm or whatever. Just tell me the specs of your comp.

ive got an assload of fans and my comps not that loud, you just have to get good ones. and I can honestly tell you that every time I added one of those fans my mainboard and cpu temps went down. fans aren't very expensive so I'd say fill up whatever space ya got.

ArrizX · 05-04-2005, 11:14 PM

actually, i dont have the computer yet...but what i wanna get is
-amd 64 3000+
-ati 128 readon graphics
-asus asrock mother bored(i think i spelled it wrong)
um.....do you need to know anythin else, or is this good, cause i dont wanna name everythink, lolz

ArrizX · 05-04-2005, 11:16 PM

lol, ok thanks ill see what i can do

winterfreshpwnz · 05-05-2005, 12:12 AM

Yeah you won't need many fans so long as the heatsink for your CPU is fine and the cables in your case aren't scattered and cluttered. Be sure to organize the wires as best you can so that the airflow can get throughout the case without a bunch of wires getting in the way.

ArrizX · 05-05-2005, 12:25 AM

oh ok

Actually, 120mm is designed to run slower (which makes less noise), but push more air out due to the larger blades.

oh, thats awesome, but i g2g, ill search for this thread, and be back on later

ASSEMBLER · 05-05-2005, 05:25 AM

i have 2 80mm fans in keeps things just right but my cpu seems to trip at about 62 degreese the 2 fans keep it at 40 - 50 degreese also i have to run a heatsink and fan for a AMD 3400+ but im about to fit a third intake fan. for the sake of a fiver it cant hurt to put extra fans in for extra peice of mind

Kage · 05-05-2005, 08:11 AM

Yeah, its always best to go for a case that provides more 120mm fans which do run slower, which means less noise, but still pushes out heat than 80mm's

When you get your computer set up, it'd be best to have ones that act as exausts (blow hot air out of the case) and ones that blow cold air in to the case which should keep a good airflow and lower temps. This just means turning around the fans.

ArrizX · 05-05-2005, 01:16 PM

so, are you saying that i need to have the two 120 mm fans blowing out the air, and turn the 80 mm fan around so that if brings air in, so i have a good air flow??

Kage · 05-05-2005, 01:18 PM

Hmm, i'd have one of the 120mm fans blowing air in, and the other blowing air out, and have the 80mm one probably blowing out too

**David Lindon** · 05-05-2005, 01:38 PM

It depends on how powerful the fans are too.

The_Other_One · 05-05-2005, 02:03 PM

The bigger the fan, the more are that can be moved at lower speeds. I have 2 120mm fans in my case running around 1600RPM and they keep it cool. Now when I crank them up to around 4000, they scream, but then it REALLY cools down this sysem.

Another thing, if you're into keeping noise down, larger ones tend to be more quiet. Now, if mine weren't on a controller, I certainly couldn't stand how loud they are on full blast.

Something else I found out, which this might be due to my case layout, I donno... But my case seems to get coolest when my rear fan is full blast and my front is at it's slowest speed. When I have them both going fast, the temp rises!

Kage · 05-05-2005, 02:06 PM

Weird. Maybe that has something to do with how the air flow moves around, and if the front one was pushing out, maybe the one blowing in at the back somehow gets pushed straight out by the front.
I might try that, though my front one blows in

Does that make sense surely if you have 120mm is bigger so it doesnt make sense cus has room for one 90mm or room for two 120mm who does this work cus 90 is smaller so you should get more in.

ArrizX · 05-05-2005, 02:08 PM

the tow 120 m fans have 4 pin connecters, and 200rpms...
