The previous generations of Raspberry Pi boards were not equipped with heat sinks or chip fans, but this generation of performance improvements caused heat dissipation. <\/p>\n\n\n\n<p>Under normal working load, the system-on-chip (SoC) temperature of the board reaches 60 \u00b0C, and the temperature reaches 60 \u00b0C to 70 \u00b0C after using the USB port. If you do some CPU-intensive work, the SoC will soon reduce performance for protection purposes. That&#8217;s why you do need heatsink any cooling fan for Raspberry Pi 4.<\/p>\n\n\n\n<p>We tested 6 different cooling cases, heatsinks and cooling fan for Raspberry Pi 4 and compare their effect when running four webpages.  <\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><a href=\"https:\/\/www.seeedstudio.com\/accessories_for_raspberry_pi.html?utm_source=blog&amp;utm_medium=blog\">SALE on Raspberry Pi 4 Accessories!<\/a> <\/h2>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter is-resized\"><img fetchpriority=\"high\" decoding=\"async\" src=\"https:\/\/blog.seeedstudio.com\/wp-content\/uploads\/2019\/11\/image-32-1030x201.png\" alt=\"\" width=\"924\" height=\"180\"\/><\/figure><\/div>\n\n\n\n<ul class=\"wp-block-list\"><li>Before we start, we have good news for Raspberry Pi 4 users!
