Rear Fan Direction Help!

I wanna know that i have a PC right now it has only 1 80mm Fan installed on the side panel of the case right over the position of CPU HSF which is sucking out the air and throwing it outwards (Exhaust). The case has a place for 120mm Fan on the rear. I have a couple of spare 120mm's and now i wanna know that if i fit it for the Intake direction (Suck air from outside to inside of the case) will it be ok? coz these 120mm's have 3 Pin connectors and they perfectly reach the pins located on the Motherboard near it (for rear fan) but the problem is i can only adjust the fan in 1 direction which is of course Intake coz the 3 Pin cable on fans is hard as hell.

Hi boogieboy

Front fan air flow in, side and back air flow out, but also side fan in depending ... as you could download SpeedFan - freeware- to tune your fans and check your temps (if supported) a good balance is best.

My rear fans and top fans all blow air out of the case. I believe in bringing in cool air from the front at the bottom and exhausting out heat from the back near the top.

There's no place and no fan in the front just on side panel and rear.

The reason for front fan/fans is to bring in air over the Hard Drive/Drives and to cool the Motherboard etc. Most front fans are at the base of the case and most back fans are at the top (making a pull through). Sorry but I would consider a new case if you intend upgrading.

That is correct. Also, fans on the side panel (if fitted) should be drawing air into the case. Basically, what you want your case fans to do is to assist in the natural flow of air through the case and since warm air rises (and the air inside the case is warmed by the hardware) you need to arrange your fans so that cool air is drawn in at the bottom front and exhausted at the top rear.

i only need to know about the directions for the Rear and Side or i think i'll just set the side panel direction for the In and the rear for the Out and extend the wires in tomorrow morning that would do the job.

There are markings (arrows) on the fans to indicate the direction of rotation and the air flow direction.

i know about the marking on the fan just need to know the ventilation direction of just 2 fans. I know about the directions when there is a place on front, bottom base, Tops, side panels etc. but i'm lookinh for the best possible directions on just 2 fans 80mm and 120mm that's it. No front, top etc.

Direction of Case Fans
I have an 80 mm fan on my heatsink that is directly below the 80 mm fan on the side of the case. The side fan is sending airflow out of the case. If I install a 120 mm fan in the rear of the case, should it draw air out of the case or into the case? Or should I reconfigure a different way?
