How to install case fan filters

Just be sure to actually clean the filters once in a blue moon. By leaving filters dirty or covered in dust, you reduce airflow and cooling power. Aside from fans and vents the other major points of ingress include the many small gaps in the chassis and adjoining pieces. From bare bones basic to flashy RGB, NeweggBusiness offers a wide selection of case fans for any build type. Optimal air pressure with a computer case is one of the most discussed and debated topics in computer cooling.

In simple terms, a computer case can either have:. If the intake CFM is greater, then you have positive pressure. If exhaust CFM is greater, then you have negative pressure. Neutral would be when intake and exhaust CFM are equal. This way, the air that enters your case goes through a filter first.

When building your computer, be sure to configure your cooling system with the principles outlined above in mind. Otherwise, you may end up with a toaster oven of a computer. Just be sure to avoid those tacky LED-equipped case fans in the office. Your negative pressure graphic is not likely as you would never exhaust out the front. A single exhaust fan with no intake fan is negative pressure.

A single intake fan with no exhaust fan is positive pressure. Different flow affects dust build up just as much as the case and house itself. You want as close to a laminar flow as you can get, which just means as smooth and unobstructed as possible. You really could have spent a little more time on this to make it easier to comprehend for the beginners. Thanks for the feedback. The first image of the fan has been replaced.

As for the pressure graphics, the arrows are supposed to represent pressure rather than airflow. Question here, how can you find out the cfm rating of the stock fans that come with a computer case? Is there any software what I can install to get these ratings as most software just gives you if the fan is working or not and at what rpm..

I have a NZXT H case, it has 1exhaust on the back and 1 on the top aswell and i have a NZXT kraken x62 for cpu liquid cooling and the radiator is mounted at the front with 2 intake fans. So my question is, should i flip the top fan to be an intake and leave the one on the back as an exhaust?

Or just make them both exhaust? That is why all the perforated side plates and back plates are that way and the fans are mounted to be exhaust only. It works pretty well stock. Reversing would be bad as the 2 are so close together they would cancel each other out in a small area and give most of the case NO airflow.

If you do add intake fans in front there is limited ventilation for them to bring in much air since the front panel is solid, and it will mess up the negative pressure design unless you upgrade to higher cfm exhaust fans too and since NZXT is also a fan maker these cases have AER f fans instead of generic cheapo fans.

There was only 1 mm exhaust fan mounted at the rear panel. This means I have positive pressure happening in my case. Should I add additional fans at the top of my case to help with proper air flow? Imo this is hard to measure just by calculation because most of the cases would provide some restriction to the front intake due to the dust filters and stuff on the front panel which makes front fans less efficient — while at least the rear fan has no restriction since there are no filters on the back.

Hey, The image of the case used is the same case I have. Can you please tell me what the case is shown in the images? Exhaust fans for expelling warm air are commonly found at the back or top of a case. The majority of cases and PCs sold today will have unused fan locations available. If you need to replace a fan, make sure you find a replacement with the correct size, and connector.

Cooling fans are available in a wide range of sizes and shapes and colors , from tiny barrel-type fans sometimes used to cool chips, to large axial fans used in most power supplies. The most common fan sizes fall in the 70mm to mm range, but fans as large as mm are becoming more popular. Fans with a diameter of mm are typical in newer cases.

Look for one with a high air flow measured in cubic feet per minute, or CFM and low noise level measured in decibels, or dBA. Fans vary in size, speed, blade shape and color. Some fans even come with built-in LED lights, others are more performance focused such as this Noctua Chromax fan. Larger fans can usually spin at lower speeds and still move plenty of air without making much noise. Some manufacturers incorporate LED lighting into their fans as well.

When adding fans to a system, maintaining positive pressure within the case can prevent dust from being sucked into any open holes or crevices. If you want to make a custom filter, you can use magnetic tape and PC case mesh sheet.

The mesh is available in large sheet form and is relatively cheap. Start by measuring the size of the hole you need to cover. Mark up the mesh, then use a sturdy pair of scissors to cut it to size.

The magnetic strip comes in a variety of lengths and widths. Press the strip firmly onto the mesh.
