Absolutely necessary with today's hardware. As technology makes notable increases, so does the temperature of this newer, faster hardware. Fast, powerful processors, and the shear amount of data throughput in todays technology creates alot of heat, which in some cases can significantly shorten the life of your hardware.
The cheapest, most efficient way of keeping those heatsinks as cool as possible it by getting all that hot air out! But dont jump right in, this guide will quickly give you some understanding on how to most effectively mount your case fans for optimal performance.
I'm writing this guide to hopefully clear up some confusion, through experience with my customers, I've come to learn that many of the custom systems they have purchased came with all of the case fans pointing inward. Great concept, not too efficient. This does not allow for optimal airflow, the cool air quickly rises to the tempurature inside the case, and then becomes trapped. It's only means for escape is through the already hot power supply. Better than NO fans, but we can do alot better.
Not only do we want to provide plenty of cool, outside air, we want to push out the heat generated by the components. Infact, your best bet is having more exhuast than intake!
Let's say you have 5 fans. 2 in the back (including the psu's fan), 1 on the side, 1 on top, and 1 in the front. Your front fan is definetely an intake fan. Your PSU (power supply unit) is definetely an exhuast. Your other rear fan needs to be an exhaust. Now we got 2 exhuast and 1 intake. So far, so good. Your first instict is to mount the side fan pointing inward, directly on the motherboard. Again, good concept, but were trying to MOVE air, not build it up. I recommend mouting the side fan as an exhuast, making 3 exhuast, and 1 intake. This is creating a vacuum inside the case, not only is the front intake providing lots of cool air, but now all the little creases, cracks, openings and small air passages are effectively pulling in cool air also. Which in turn, is cooling areas of the computer that normally would not cool, especially if you have all the fans pointing inward.
You've got one more fan, the top. Make it an exhuast also? Good concept.. its the top of the case, where the heat builds up at, but the PSU and the rear fan is plenty enough for exhausting heat. Since we got only have 1 intake, I would recommend mounting the top fan as an intake. Increasing the cool air flow through the top of the case increases the effectiveness of the entire vacuum fan system, and its still more exhaust then intake! Excellent! Your hardware greatly benefits from remaining as cool as possible.
If you already had this general idea, great! Please still vote for this guide, and if this helped you in any way, your helpfulness vote is greatly appreciated! Thanks!
