Do you guys notice any difference applying intake fans?? :?:

[61Dynamic]

It all depends. It can be benifical to have one installed if you have sufficiant fans pulling air out the back of your PC. If you have too many you can actually hinder airflow adn cooling by creating positive pressure inside your case.

If your not overclocking I wouldn't be to concerned with it. Just don't block the vents in the front. If you are overvlocking or running a mean rig with 3 or 4 fans blowing out the back, then a fan up front could help.

The best way to find out though is to measure the temp inside the case and play around with fan combonations. You might fiind that you can get more than sufficiant cooling with less fans and end up saving your ears from a lot of noise.

you want the same "in" as "out"

draw the airflow out on paper.

I have two in the front and one on my window on the side pulling air out and one in the back pulling air in, and i seem to be doing fine. I don't know if what i'm doing is good or bad, but if anyone has comments on it, tell me lol.

[[GF]Burke]

2 in, 2 out.

front to back.

I had the two in the front as intakes but i found that lot of the dust in the air was being sucked in and brought into the case. There isn't as much floating around the back of the case.

I got mine at CompUSA ..you can get all diffrnt sizes... 60mm-120mm

[imported_Yoshi]

yes you definately want to balance your airflow. Your exhaust fans can only remove as much air as goes in the case.
The reason for front to back is the back of the case is, ther is more hot air in the back so you want to bring air in from cool side of case. Also most of the time the back of the case is near a wall so it does not get the cold airflow the front does.
Use the filters and clean out your case regularly. I vacuum mine out every couple weeks.

[[GF]Burke]

u use a vacuum??? :shock: wow.. talk about static..

that shocks me you say that.. weirdness.. now i feal i was tought diffrntly/wrong

[imported_Yoshi]

yeah.... I am not the most careful person with static. I will be biten by it at some point I know.
You were taught correct, static should be avoided. I am just a little to lazy to remove all the compents before cleaning the case out which is what should be done.

[[GF]Burke]

lol, k

i just use condensed air. (and filters)

[n0strax]

I have the removeable motherboard tray, so I just disconnect the cables and take it out and then I vaccum it out and use condensed air for the little places. I'm sure it's still not very safe, but I feel alot safer than if the mobo was still inside.

You don't have to have the same number of intake fans as exhaust fans for sufficiant cooling. If you only have 2 fans blowing out the back, cool air will still enter the case through the front. It's the basic principles behind vacuum.
The fans in the back create negative pressure in the case and thus cool air is drawn in through the front. In fact, thats how car engines work.
If you have multiple fans in the back, having at least one in the front will help increase how efficiently they work.
No one can say for sure how many fans you need to draw air in or out. They can only give you a guideline to go by. It varies system to system. Fan placement, obstrucions in the case, size of case, etc all can have an effect on cooling.
Having at least 2 fans in the back, and one blowing on the graphics card, and one in the front blowing inward is a good place to start for a gaming rig.
Like I said before, the best way to find out is to measure the temp inside of the case.

Sorry 'bout the length :wink:

[apeter]

I've got 2 80's and whatever 's in my PSU blowing out, I had been using an 80 for an intake, but it's cooler without :?, so all my fans are exhaust

yeah.... I am not the most careful person with static.
I've drug my mobo around on the carpet before... :shock:

[[GF]Burke]

sucking= restrictions. IE= vacuum. (loud/restrictive)

you DO want even "IN"/"OUT" for best airflow.

[61Dynamic]

Thats correct. Whatever is pulled in needs to be let out equally and visa-versa. But the number of intake fans do not have to be equal to the number of exhaust fans as you can see in apeter's example.

[[GF]Burke]

correct.

me personally, i run 2 80mm in, 2 80mm out. all the same speeds (its a chieftec case) and i do not use a side fan, that just didnt make since on paper.

[61Dynamic]

Yea, I think a side fan is more of a way to cool the graphics card more directly than anything else. I don't think it would make too much of a difference (good or bad) for ambient temp inside PC unless the fan is real big.

[WVJammer]

I'm just finishing my first mod, and I was thinking of using 2 80mm intake,
and 120mm out, through the top. How do you think?
