If a fan is noisy from a cold start-up but goes quieter as it spins, be sure to replace it as it will most likely give you problems later on. You will then be clear on which fans you need to replace. If you have any that are noisy, disconnect them one at a time until the noise is gone. Take note of how many intake fans you have versus the number of exhaust fans. Take a look at the fans that you currently have on your PC.
This leaves very little chance for stagnant air hanging around to warm up and to cause the internal temperature to rise above desired levels. Having positive air pressure means that the air will be drawn primarily from your intake fan(s), and as I’ve mentioned, the air is easier to filter.Ī standard air filter can be installed in front of your intake fan(s) if your case doesn’t have one to ensure that cleaner and more dust-free air is drawn into your case.īecause the airflow is more balanced, plenty enough air is still exhausted, which means that plenty enough air is flowing in and out. This is what I have found to be the best in terms of keeping things cool and clean. If these conditions are present, it can be argued that the case may remain clean for longer periods of time. The computer case cannot have too many intake areas that are unfiltered.The filter must have the correct cross flow rate.The filter must have the correct pore size and density.There must be a large enough intake area that is filtered.However, in some unique instances, you could have a situation where a negative air pressure configuration won’t draw in much dust. This is because air may be drawn in where the is no place to add a filter. It is also more difficult to add filters to the intake areas of the case that specifically draw air in through them exclusively. While it is an effective way to cool your system, it can quite often result in more dust being pulled into your case over time. Side note: The same points listed here can be applied to any fan configuration when comparing airflow rates. The exhaust fan has a higher airflow rate specification compared to the intake fan.
The exhaust fan spins faster and is the same size compared with the intake fan.More exhaust fans of the same size or larger than intake fans.
And, of course, we are referring to all the fans inside the case as a collective. The exhaust fan(s) have a higher airflow rate compared to that of the intake fan(s). Negative air pressure means that more air is going out than in. Intake fan: The blowing side is facing the inside of the case and draws air from outside the case and blows it inside.It draws air from inside the case and blows it outside. Exhaust fan: This is the fan that has its blowing side mounted to the wall of the case.To help you understand my explanation better, here are the two types of fans I will be referring to: We will start out by taking a look at the three ways to configure cooling. The main three types of airflow configurations Here’s a link to my review of the top CPU cooler on the market. A complete understanding so you can configure cooling like a pro. The true challenge is keeping it cool, quiet, and clean as time passes. I’ll just mention though, that it’s easy enough to create decent airflow through the inside of a computer case and get the system temperature down to acceptable levels. So I’m going to share all of them and point out which one I recommend based on my experience after building hundreds of computers from scratch. There are various ways that you can configure the fans to give you different results. Recommended graphics card cooling fan configuration.Make sure that there aren't any obstructions to the airflow.
