That way, when you\u2019re performing CPU-intensive tasks, the PWM connector increases the voltage to the fan, making it run faster to keep the CPU cooler. Once you reduce the CPU workload, the fan slows down automatically.<\/p>\n<p>A 3-pin DC connector runs on full power, which isn\u2019t easy to control using software. Instead, you control its speed by regulating how much power flows to it - which can be unreliable.<\/p>\n<p>If your PC has a Molex connector that takes all its power from the power supply unit, you can only control it using a resistor cable, which isn\u2019t as dynamic as a PWM.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"BIOS\"><\/span>BIOS<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Back to the BIOS.<\/p>\n<p>If your PC BIOS allows it, you can control your CPU fan speeds from here.<\/p>\n<p>Each manufacturer deploys different BIOS software for all their devices, so there is no clear-cut way that applies to all brands. However, the Menus are very similar and you\u2019ll be looking for settings or tabs that manage hardware (monitoring).<\/p>\n<p>Once you get to this tab:<\/p>\n<ul>\n<li>Select the type of fan your PC uses. It may be DC or PWM.<\/li>\n<li>Choose between modes. Often, you\u2019ll choose between full speed, automatic (or performance), and silent modes.<\/li>\n<li>Some BIOS software will allow you to change the temperature threshold. Ideally, you want your CPU to run below 70 degrees. Therefore, set it to run at higher RPMs once temperatures approach 65 degrees.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Setting_the_Fan_Curve_in_the_BIOS\"><\/span>Setting the Fan Curve in the BIOS<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>If your system uses UEFI BIOS, you can configure your CPU fan curve, primarily if it uses a PWM or DC connector.<\/p>\n<p>The fan curve is a graph with fan speeds on the vertical axis and CPU temperature on the horizontal axis. You can manually plot a line graph that controls the behavior of your CPU fan once your processor hits a specific core temperature.<\/p>\n<div id=\"attachment_16998\" style=\"width: 977px\" class=\"wp-caption alignnone\"><noscript><img aria-describedby=\"caption-attachment-16998\" decoding=\"async\" class=\"size-full wp-image-16998\" src=\"https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/05\/Custom-fan-curve-MSI-BIOS.jpg\" alt=\"Custom fan curve MSI BIOS\" width=\"977\" height=\"741\" srcset=\"https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/05\/Custom-fan-curve-MSI-BIOS.jpg 977w, https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/05\/Custom-fan-curve-MSI-BIOS-300x228.jpg 300w, https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/05\/Custom-fan-curve-MSI-BIOS-768x582.jpg 768w\" sizes=\"(max-width: 977px) 100vw, 977px\"><\/noscript><img aria-describedby=\"caption-attachment-16998\" decoding=\"async\" class=\"size-full wp-image-16998 lazyload\" src=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20viewBox%3D%220%200%20977%20741%22%3E%3C%2Fsvg%3E\" alt=\"Custom fan curve MSI BIOS\" width=\"977\" height=\"741\" srcset=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20viewBox%3D%220%200%20977%20741%22%3E%3C%2Fsvg%3E 977w\" sizes=\"(max-width: 977px) 100vw, 977px\" data-srcset=\"https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/05\/Custom-fan-curve-MSI-BIOS.jpg 977w, https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/05\/Custom-fan-curve-MSI-BIOS-300x228.jpg 300w, https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/05\/Custom-fan-curve-MSI-BIOS-768x582.jpg 768w\" data-src=\"https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/05\/Custom-fan-curve-MSI-BIOS.jpg\"><p id=\"caption-attachment-16998\" class=\"wp-caption-text\">Source: <a href=\"https:\/\/forum-en.msi.com\/index.php?threads\/guide-how-to-set-up-a-fan-curve-in-the-bios.369711\/\" target=\"_blank\" rel=\"noopener\">MSI<\/a><\/p><\/div>\n<p>You can set your fan to <em>statically<\/em> run at specific speeds or <em>dynamically<\/em> adjust to the CPU's temperature - which is the recommended option for most cases.<\/p>\n<p>Once you\u2019ve made your changes, you save your configuration and restart your device.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Speedfan\"><\/span>Speedfan<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Speedfan is another powerful speed control tool.<\/p>\n<div id=\"attachment_16999\" style=\"width: 476px\" class=\"wp-caption alignnone\"><noscript><img aria-describedby=\"caption-attachment-16999\" decoding=\"async\" class=\"img-with-border wp-image-16999 size-full\" src=\"https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/05\/SpeedFan-fan-control.png\" alt=\"SpeedFan fan control\" width=\"476\" height=\"354\" srcset=\"https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/05\/SpeedFan-fan-control.png 476w, https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/05\/SpeedFan-fan-control-300x223.png 300w\" sizes=\"(max-width: 476px) 100vw, 476px\"><\/noscript><img aria-describedby=\"caption-attachment-16999\" decoding=\"async\" class=\"img-with-border wp-image-16999 size-full lazyload\" src=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20viewBox%3D%220%200%20476%20354%22%3E%3C%2Fsvg%3E\" alt=\"SpeedFan fan control\" width=\"476\" height=\"354\" srcset=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20viewBox%3D%220%200%20476%20354%22%3E%3C%2Fsvg%3E 476w\" sizes=\"(max-width: 476px) 100vw, 476px\" data-srcset=\"https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/05\/SpeedFan-fan-control.png 476w, https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/05\/SpeedFan-fan-control-300x223.png 300w\" data-src=\"https:\/\/g100.us\/wp-content\/uploads\/media\/2022\/05\/SpeedFan-fan-control.png\"><p id=\"caption-attachment-16999\" class=\"wp-caption-text\">Source: <a href=\"https:\/\/www.almico.com\/sfarticle.php?id=5\" target=\"_blank\" rel=\"noopener\">Almico<\/a><\/p><\/div>\n<p>You use Speedfan to control CPU fan speeds:<\/p>\n<ul>\n<li>Install and open the Speedfan app on your PC.<\/li>\n<li>Take some time to get familiar with Speedfan and understand how it works.
