Talking Improve Cooling System

My ATX casing has a fan funnel mounted on it since it was designed for LGA 775 mainboards. In order to provide more adequate supply of fresh cold air to the CPU fan, I removed the funnel, reduce its size so that it will not touch the CPU fan, and attached it to an 8 cm chassis fan and screw the chassis fan on the side of the casing that has holes in it. In this way more supply of air enters directly to the CPU fan. When I powered on the computer, I discovered that the processor and system temperature dropped. It also reduced the heat generated by the power supply which is directly above the processor. The only disadvantage is more noise is added to the system.

Hi, I need someone to help me about the fan as soon as possible.
Gabriel Torres said that "fans at the computerís rear should be fitted in the exhaust direction" so does that mean that this installation guide:http://www.evercool.com.tw/install/instal_sff.htm is wrong?
Because the guide shows that the fan is facing inside (that is pulling cold air in right?). To pull the hot air out, isn't the fan suppose to be facing outside like the power supply?
The technician install the spider fan in my computer facing outside but the guide shows that it's the other way around. Which is correct??? I'm very confused, @o@.

Most fans I've seen have an arrow to show the direction of air flow. If you can't find this, test it to see which way the air blows. Then you should be able to screw it on to the case any way you want.

Fans on the back should be exhaust or blowing air out the back.

In a standard tower configuration, yes, the rear fan should blow air out of the case. Most fans show the direction of airflow (and sometimes rotation) as a small arrow embossed somewhere on the side of the fan housing. Also, a typical fan sucks air from the exposed side and exhausts it on the side where the fan motor actually mounts to the housing. In the picture below, you're looking at the exhaust side of the fan.



It looks like your fan is configurable, so if you want it inside the case, then the spiderweb cover could be moved to the intake side. Although I don't see why anyone would put a filter on a fan that's blowing air out of a case, unless it was to keep the fan blades clean. The intake is where you need the filter.

Then is this installation guide:http://www.evercool.com.tw/install/instal_sff.htm CORRECT???
Because the installation guide shows that the exhaust side would be facing inside the cpu case, not outside.

A computer case needs to evacuate the heat created by the components inside. This includes not only the CPU, but the other components on the motherboard. In terms of airflow balance, a case will remain cooler if there is more air being sucked out than blown in.

Regardless of what evercool's instructions say, unless you have additional fans sucking air out of the case, you won't see any benefit by having front and back fans blowing into the case.

Case in point (no pun intended): My current system sucks air in from the front and back. But, I have two fans on the transparent side cover that suck air out. The overall airflow is balanced. The air from the rear fan travels over the motherboard, while the air from the front fan travels over the hard disks, then the motherboard. The streams converge over the video card in the center, where the two fans mounted on the side suck air out from that area. So, overall, I run very cool temps inside my case, because of managed airflow.

You can't always trust what a manufacturer's instructions tell you to do. If you have additional fans, like I do, sucking air out from another location in the case, then it's acceptable to draw air in from the rear. But, if you set up a case with just air being sucked in, with no way to evacuate, the case will run hot.

Hope this helps.
