(Cans of clean, compressed air are also available from hardware stores or online - I've never used them. That Dell does not have much in the way of removable panels, and the keyboard is a beast to remove, so concentrated on vent holes and I think I sprayed some electrical contact cleaner and let it dry out, between vacuum sessions. First though, I took a small tank vacuum cleaner with a fairly powerful crevice attachment and sucked out everything from every available opening. (If you think it's a Mint setting, try booting a live USB of some other OS and see if the problem is resolved.)Īfter a lot of fooling around with fan control software on both systems, I was considering taking it to a repair shop to see about replacing hardware. Behavior on Windows confirmed it wasn't just the Mint OS. I went through a round of frozen fan / overheating shutdowns on my Dell 1520 some years ago, at that time a Mint / Win7 dual boot. Step 4: If that resolves the overheating, you can either try Mint again (Maybe XFCE over Cinnamon as that can reduce temps a bit) and put in some cooling help (extra fans blowing air into the system etc) and learn to work around the overheating issue (as i do on this old acer) OR just use Ubuntu. Step 3: If that does not help, think about trying regular Ubuntu and see if the temp issue goes away. Step 2: If no, then go through the link info in my sig. Step 1: Check if you have a GPU that needs a correct driver setting up. You might find for example that regular Ubuntu (that Mint is based on) will not overheat your hardware, so that is always an option to look into as you work through the trouble-shooting process. IF that is the problem you end up facing and you can find no fix for it, you can live with it (like i do on this old acer laptop) and be careful how you use it, or try a different distro even. Some hardware just has an issue with Mint. You might not have a GPU on your system so this might not be the exact issue, but in all cases where people notice overheating in their system, you need to be careful and try to resolve the issue as soon as possible and as well as you can.įor example the old acer laptop i'm typing this message from also over-heats (i can't watch youtube video's on it for longer than 20mins etc), and that is after using the tips in the link in my sing and having it placed on one of those laptop pad cooler things. I was not able to get the system to take a GPU driver that would stop the default non GPU Nouveau from loading that meant after i had logged into the system, the GPU fans would not function. The laptop (an old but expensive HP) that cooked itself to death was having trouble due to the GPU card, and it was ultimately the GPU card that generated the heat that killed the system. You can have a read through the link in my sig just in case that helps also. You could try going into the bios and seeing if you can change fan settings in there (to run sooner at lower heat levels than the default setting). You might have a laptop that will cook itself to death (i had one years ago that did that). I've updated all drivers and installed all updates on Windows Update.Be careful. I can open Task Manager -> Processes and watch all the start-up processes raise the CPU load and the fans will speed up to the expected level.Īt 1 minutes and 54 seconds, a process called "Dell Instrumentation" will start using about 27% of the CPU and the fans will speed up to full and stay there, even after this dell instrumentation process goes down to 0% about 10 seconds later. When I boot up, the fans are running normally at first. When I shut down, the fans stay spinning at full speed right under the laptop powers off, where they immediately stop. Using Open Hardware Monitor, I can see the 4 CPU cores are at 43 - 53 degrees C, so this isn't due to overheating. I have the laptop set to use the integrated GPU instead of the dedicated GPU so the GPU is usually a 0% usage. I have an Alienware 14 laptop that I use mainly for web browsing that developed an issue a couple of days ago where the fan would be spinning at full speed regardless of how much load the CPU was under.
