There essentially are three different situations in the\ncase.<\/p>\n\n\n\n<ul><li>Positive pressure<\/li><li>Negative pressure<\/li><li>Neutral<\/li><\/ul>\n\n\n\n<p>Neutral\npressure simply means that the amount of air coming in is equal to\nthe amount going out. Positive pressure is when more air comes in\ncompared to the amount going out and conversely the negative pressure\nis when more air is coming out compared to coming in.<\/p>\n\n\n\n<p>It\nis impossible to be truly positive or negative pressure, in that\nsituation the extra pressure will equalize via any crack or opening\nin the case. \n<\/p>\n\n\n\n<p>Obviously\nthe best case would be neutral pressure but failing that positive\npressure would be the next best.  The over pressure will escape via\ncracks.  This usually means that the incoming air is filtered and\nthen escapes but the negative pressure situation will have unfiltered\nair entering into the case via all cracks or openings.  The\nunfiltered air means that dirt will begin to accumulate in your case.<\/p>\n\n\n\n<p>There\nare different sizes of fans but the most common sizes are 120mm and\n140mm.  Larger fans will push more air which means that they can spin\nslower and will be quieter.<\/p>\n\n\n\n<p>Air pressure\nexamples<\/p>\n\n\n\n<figure class=\"wp-block-embed-youtube wp-block-embed is-type-video is-provider-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Computer Case Airflow - What is Positive and Negative Pressure?\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/sh6F2eccMec?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The CPU is going to get hot, really hot and so you need to keep it cool.
