I'm using Peppermint OS 7 (which is based on Ubuntu 16.04 i think) and my fan is speeding up for no reason (just browsing the web opening few tabs, not even a video).CPU : 5-10% usage RAM : 2400/58xx usage Laptop : Dell Inspiron-3521 Here are the outputs of some commands for information : inxi -Fz :System:    Host: ly-Inspiron-3521 Kernel: 4.4.0-67-generic x86_64 (64 bit)           Desktop: N/A Distro: Peppermint SevenMachine:   System: Dell product: Inspiron 3521 v: A12           Mobo: Dell model: 06X37M v: A02 Bios: Dell v: A12 date: 10/25/2013CPU:       Dual core Intel Core i5-3337U (-HT-MCP-) cache: 3072 KB            clock speeds: max: 2700 MHz 1: 1181 MHz 2: 896 MHz 3: 814 MHz           4: 824 MHzGraphics:  Card-1: Intel 3rd Gen Core processor Graphics Controller           Card-2: Advanced Micro Devices [AMD/ATI] Mars [Radeon HD 8730M]           Display Server: X.Org 1.18.4 drivers: ati,radeon,intel (unloaded: fbdev,vesa)           Resolution: 1366x768@60.00hz           GLX Renderer: Mesa DRI Intel Ivybridge Mobile           GLX Version: 3.0 Mesa 12.0.6Audio:     Card Intel 7 Series/C210 Series Family High Definition Audio Controller           driver: snd_hda_intel           Sound: Advanced Linux Sound Architecture v: k4.4.0-67-genericNetwork:   Card-1: Realtek RTL8101/2/6E PCI Express Fast/Gigabit Ethernet controller           driver: r8169           IF: enp7s0 state: up speed: 100 Mbps duplex: full mac: <filter>           Card-2: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter           driver: ath9k           IF: wlp8s0 state: down mac: <filter>           Card-3: Atheros           IF: null-if-id state: N/A speed: N/A duplex: N/A mac: N/ADrives:    HDD Total Size: 1000.2GB (24.1% used)           ID-1: /dev/sda model: WDC_WD10JPVX size: 1000.2GBPartition: ID-1: / size: 263G used: 41G (17%) fs: ext4 dev: /dev/sda5           ID-2: swap-1 size: 6.31GB used: 0.01GB (0%) fs: swap dev: /dev/sda6RAID:      No RAID devices: /proc/mdstat, md_mod kernel module presentSensors:   System Temperatures: cpu: 50.0C mobo: N/A gpu: N/A           Fan Speeds (in rpm): cpu: 0Info:      Processes: 204 Uptime: 8:24 Memory: 2436.2/5854.7MB           Client: Shell (bash) inxi: 2.2.35 sensors :radeon-pci-0100Adapter: PCI adaptertemp1:            N/A  (crit = +120.0C, hyst = +90.0C)coretemp-isa-0000Adapter: ISA adapterPhysical id 0:  +42.0C  (high = +87.0C, crit = +105.0C)Core 0:         +39.0C  (high = +87.0C, crit = +105.0C)Core 1:         +42.0C  (high = +87.0C, crit = +105.0C)dell_smm-virtual-0Adapter: Virtual devicefan1:        5100 RPMI'm dual-booting Linux with Windows 7 and that I don't have this problem with windows (of course the fan speeds up when I'm playing video games because they are consuming too much resources, but it doesn't speed like Linux does when I'm just browsing the web or working with some apps like Eclipse/Brackets and such, I rarely consume more than 3Gb of RAM)When I started typing this message, my fan started speeding up, then stopped for a moment, then speed, then stopped, and so on... It seems to be doing it randomly as well as when I perform some actions like opening 1-2 youtube videos.I'm suspecting my video adapter's drivers are not being well managed by Linux
Fan Speeding up for nothing
