im gonna be adding some windows and blow holes to my case real soon

now, ive done 80mm fans before but never any larger in mods,

would adding 2 120mm fans to the door, and 2 to the top window im adding be overkill?? im into overclocking and want to get every bit of cooling i can get my hands on

do the 120s drain more power, or make more noise??
 
i looked into it, and on average they produdce like 3 times the air flow and 1 and a 3rd the noise

so do you guys think its worth it??

or is it over kill to have 4 120s in your case?
 
I think 4 would be a bit much, but it all depends on if your oc'ing or not. If you're using a regular sized mid-tower I'd think 2 would be fine, 3 good.

120mm can run at slower speeds then 80mm and push the same amount of air, hense slower speed = lower decible :) 120>80
 
it should work fine. in the cubes and in Thermaltake cases ive seen people have modded all of there 80 and 92mm fans to 120mm. i dont think it should be a problem. how high are you OCing? mabey you might want to think about a watercooler. there a little expensive but worth it. somtimes you can find one for about 100 dollars. but i havnt been that lucky.
 
yah, im deff. ocing, so i want all the cooling possible

so, 1 on the top, and 1 on the door, or 2 on both just to show how [H]ard Core i am?
 
4 is complete and utter overkill. A single 120mm can do the work of 2-3 80mm fans depending on its CFM.

One on the side panel and one on top will move more then enough airflow inside that case, even if your overclocking to the extreme.
 
Bah, I've got five 120mms on my case and nine 80mms (all high speed to boot :eek: ). So four 120s should be fine :D

Mind you, I can turn 'em off.
 
id probably rig up a speed controler on them so i can crank em down when im dling for long periods like at night, or just not realy putting much stress on it

i would love to watercool, but i realy dont want to watercool my system if all i can affford is a cheap-o system, i want somthing nice if im gonna watercool

should i go for it or not?
 
i'm putting one fan in the front and one in the back. should i make the front intake and the back exhaust?
 
I'd go with the 120 only if you have a fan controller. They are incredibly loud.

YES!!!!!!

Watercooling is by far superior to air cooling. Just by setting up watercooling on my rig I dropped by 10 c, without any changes to my fan setup. At stock my barton 2500 was running at 27c with a case temp of 26c. So, go for it, drop the extra 250 or so bucks and get wet!

OK think about this if you go with 100 cfm fans that means with one blowing in and one blowing out you are replacing the air in even the largest cases every 3 seconds. I don't think knocking it down to 1.5 seconds is going to cause any OCing improvements. You are still going to have the air around your heatsink at the same temp as the ambient air. There will be no gain from doubling it. Also 2 120's look like crap in the top of cases.
 
The thing I like best about 120mm fans is that what noise they do make is a low-pitched whirrrr.

I can't stand the high pitched whine of 60mm fans and some 80mm fans.
 
would this fan controler work well?? or do i need somthing with more a little more kick?? im pretty confident that it would easily power them but i just wanted to double check

Ps-Rage, if you were not a Mod, I would say your either lying or your MBM is configured wrong. But, on that note, with a case temps of 20c no wonder you're running so damn chilly :p
 
My office is in the basement - chilly down here all year round. Without all the fans blasting, at idle I see case temps at 30C and CPU temps at 36C. But once I turn the wind tunnel on.....
 
heh, with that hell of a rig you have no doubt :D

On air right now my case temps idle at around 31, cpu temps around 32. Im using the Aero 7+ in a cheapy case I got from PcClub, with a 80mm in the rear and 80mm in the front and a rats nest of wiring (this is my puters temp home while I redo my watercooling).
 
That, by the way, is a 3G Northwood with a Thermalright SP-94 that has a 92mm Delta on it


:D
 
lol, anyone care to answer my questions instead of drooling over rage's temps?
 
Ack sorry! But you have to admit, his case is worth drooling over :D

Well, without know what size case you have, whats in the way of the fans, where the airflow is I really could not say if more than 2 120's would make a dif or not. It all depends on the space you have, obstructions to air flow, and how much air you need to move. I would say in most mid/full tower cases 2 120's would sufice. For a full server tower *6 external 5.25" bays or more* I would use three, one in front for intake, one on top for exaust and one in back for exaust. But, again it comes down to your case. I would say do two, and if the results are not what you were wanting, add a few more in.
 
Shoehorning 4 120mms into that case would be difficult. I would lose the bottom 3 1/2" drive cage and put one there and another out the top in the center. I also am a fan (heh, pun) of side intakes. So perhaps, two filtered Panaflo intakes (low speed) for the front and side and one medium speed for the top exhaust. Panaflos are as quiet as everyone says. I have two 80mm low spin Panaflos in my server and they are whisper quiet
 
i was planning on adding to the current fan aray, 2 intakes on the side, and 2 exaust on top
 
One thing to remember, keep your airflow balanced. Too much negitive or positive airflow will cause dead spots in your airflow, making that spot a hot spot. Personally I would put a 120 in the front, a 92mm up top for an exaust, two 80's in back and maybe a 80 side intake up towards the front to balance out my + to my - airflow.

I agree, two 120mm at top for exaust is way to crowded, if you could even fit them up there. Maybe two 80mm's set at low spin, but thats as high as I would go if your dead set on doing two fans on top.
 
You don't have the space for two top exhausts. Putting one above that power supply isn't going to do anything
 
after some measuing, i dont think i could comfortably squeeze 120s up top

so im gonna go for just one up top, and one on the side

so that would be a total of

2x 80s
and 1x 120 for intake

and 2x 80s
as well as 1x 120 for exaust + my psu exaust

i also have a slot for a 90 on the other door that is mounted on the mobo tray, think i should use it to ballence out the air?
 
If its just blowing at the mobo tray it is a waste of money. If it is actually blowing against the back of the slug, I would probably do it (but I'm a fan freak so...)
 
Yeah, the new chieftec cases have put a fan grill on the mobo directly oposite of the hard drive cages on the mobo side. How effective it is I dunno, but its kinda cool they are using that whole space on the right hand side finally.
