The fan was constantly speeding up after booting, but CPU usage still hovered between 8 and 12%. I recorded temperatures reaching 65\u00b0C, which is hot but not dangerously high. I tried cleaning the vents, and I also replaced the thermal paste.<\/p>\n<p>But things were not adding up. It felt more like the system was overreacting than overheating. It took a lot of prying into Ubuntu&#8217;s power management stack for me to realize I wasn&#8217;t facing a cooling problem. This was a coordination problem, and I needed to fix it to control my laptop fan.<\/p>\n<h2 id=\"the-fan-wasn-rsquo-t-reacting-to-temperature-mdash-it-was-reacting-to-frequency\">\n                        The fan wasn\u2019t reacting to temperature \u2014 it was reacting to frequency<br \/>\n               <\/h2>\n<h3 id=\"why-60-deg-c-can-still-sound-like-90-deg-c\">\n            Why 60\u00b0C can still sound like 90\u00b0C<br \/>\n    <\/h3>\n<p>        Afam Onyimadu \/ MUO<\/p>\n<p> Ignoring noise or sounds from your laptop can be costly. In the past, I only observed the temperature, but my understanding began when I started looking at the CPU frequency. My CPU wasn&#8217;t permanently hovering around 100%. However, tiny bursts of work were constantly resulting in short spikes in clock speed. When the spikes occurred, voltage and package power increased and caused the fan controller to react.<\/p>\n<p>Because cooling systems are designed to react before temperatures become catastrophic, a rising power draw can trigger a response. This creates a situation where the average temperature stays within&#8230;<\/p>\n<p><a href=\"https:\/\/www.makeuseof.com\/finally-fixed-linux-laptops-constant-fan-noise-it-wasnt-hardware\/\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I finally fixed my Linux laptop\u2019s constant fan noise \u2014 it wasn\u2019t the hardware https:\/\/www.makeuseof.com\/finally-fixed-linux-laptops-constant-fan-noise-it-wasnt-hardware\/&#8230;<\/p>\n","protected":false},"author":1,"featured_media":216333,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/static0.makeuseofimages.com\/wordpress\/wp-content\/uploads\/wm\/2026\/02\/diagnosing-from-linux-monitoring-app.jpg?w=1600&h=900&fit=crop","fifu_image_alt":"","footnotes":""},"categories":[48],"tags":[71,79],"class_list":["post-216332","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-linux","tag-linux","tag-ubuntu"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/216332"}],"collection":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/comments?post=216332"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/216332\/revisions"}],"predecessor-version":[{"id":216334,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/216332\/revisions\/216334"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/216333"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=216332"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=216332"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=216332"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
