I have an Acer V17 Nitro with Windows 8. The temperatures get way too hot on this laptop, even when using very non-demanding applications.   How do I lower the throttling temperature so that it begins throttling CPU down at say 80 deg C instead of 96 deg C?   I don't care if performance is impacted, I don't want to burn a hole in the laptop.   Thanks,

I've seen a lot of posts about disabling the throttling temperatures but none regarding setting them.  I have an Acer V17 Nitro, i7 laptop and it's CPU temperature reaches 95°C before throttling. It's a very powerful laptop, crippled by a bad cooling system. I already undervolted by 70mV and disabled hyper boost.   Currently, I have to go into Power Options and adjust Maximum CPU Frequency between 40% and 80% to keep the temperatures under 80°C. But this depends on the application. And I have to do this manually for each application I'm using.  Ironically, some applications (especially Fortnite) will run just fine with the CPU frequency set to 30-40% with the temperatures only rising to 80°C, while others will run at the same temperatures with the maximum frequency set to 80%. It just depends on how the code was written and how many cores are being used.  I know the throttling temperature is set to 95°C for the CPU, but even if it doesn't melt the CPU, it can cause a lot of other issues, like melting the case.  I would prefer to lower the throttling temperature to something like 80°C. This way I don't have to adjust the maximum CPU frequency by hand every time.  Is there a way to do this from the BIOS? From Windows? Via a third party app?

So I have a Compaq CQ50-215CA and my sister was using her laptop on her bed and I was just using it quickly to check my email. The surface of the laptop was really hot and I opened Speccy to see that the CPU and GPU temperature was 96 C. A couple months ago, my laptop was on the desk without a cooling pad and I was playing a game. Using GPU-Z back then, I had a reading of 104 C. Even with a cooling pad on a desk, running several processes/games keeps me around 88-90 C.  Is this normal for a laptop and what's the highest temperature the internals can handle? Besides a cooling pad, are there any other more effective ways of cooling a laptop?

I remember changing some values to disable Deep sleep mode and hibernation a few months ago, and realised that my battery drains faster now. I just want to revert all settings to default. I changed some back such as hibernationmode 3, but not sure if I'm missing anything else.  Are these values normal for a 15" Retina Macbook Pro ?

My 1yr old laptop, HP Pavilion 15 has it's CPU, Intel i5-8300H stuck at 0.78 GHz whenever it's plugged and charging, and the moment I remove the charger plug or switch it off, it increases suddenly and keep fluctuating freely, with good utilisation percentage more than 1-2GHz or more as I experience Thermal Throttling. I tried sneaking into the BIOS to see if I can do anything, but found nothing. I also downloaded Intel Extreme Tuning Utility (XTU) but couldn't control it. My question is how do I increase the speed to say atleast 2 GHz (fixed, not fluctuating) when it's charging, irrespective of getting thermal throttle, and also maybe even control the fan speed if it does get hot?

I have a laptop that's running on the following:   MSI MS-1634X motherboard AMD Turion X2 TL-66 CPU ATI Mobility Radeon HD2600   It keeps overheating, especially when I do something more CPU and GPU-intensive such as games. I've tried SpeedFan and Notebook Hardware Control and neither are able to help control my fans. I also have a Targus Chillmat for my laptop which helps cool down my laptop, but it still overheats. Are there any fan controlling programs that I could use to maybe turn up the RPMs on my fans or any other ways to cool down my laptop? My laptop runs pretty hot, maybe 80c core when being used, not even intensively. The Hard drive stays cool though, close to 35c.  Any help is appreciated. Thanks!

Don't Know why my PC heats up while i use ubuntu (any version). I have dell i7 processor system with 1 GB nvidia. Still finding solution but no positive and effective solution found. any suggestion

I generally keep my laptop on 24x7, and at the end of the day it's really annoying to have my thighs burnt because over overheating.   The overheating seems to be a result of WMI Provider Host (WmiPrvSE.exe) spiking the CPU utilization to 25% every few minutes.  Why does this happen?  I have an HP Envy 14 (with the HP bundled crap) running on Windows 7 Home Premium.  (Note: Based on @nhinkle's , it seems that HP Wireless Manager might be the culprit, is there any way to confirm this?)     This question was a .

I accidentally clicked on the option "When power is critically low" under System Settings>Power. The original entry was blank, but the only two options after I clicked were Hibernate and Shutdown. I want to set it back to Suspend.

Is there a Windows standard way to do things such as "start fan", "decrease speed" or the like, from C/C++?  I have a suspicion it might be ACPI, but I am a frail mortal and cannot read that kind of documentation.  Edit: e.g. Windows 7 lets you select in your power plan options such as "passive cooling" (only when things get hot?) vs. "active cooling" (keep the CPU proactively cool?). It seems the OS does have a way to control the fan generically.

Is there any tool that helps to determine the weakest link of my current laptop hardware specification? Any online guide to help me choose nice balanced configuration for the new laptop?    I need to find the answers:  a) which component should be invested to increase overall performance the most? CPU? GPU? RAM?  b) which component may decrease overall performance and work as a bottleneck for the specific configuration?    The question is general and regards both to validating the current hardware usage (and its possible bottlenecks) and estimating the performance (and avoiding possible issues) of specs I'm going to choose and buy.    P.S. For the specific laptop I need to replace, the following software will be in use:    Windows antivirus, firewall, dropbox service running in the background mail app + web browser with a dozen or so tabs open from time to time: libreoffice apps, movies, games (both online and installed).

What are the pros and cons of controlling (lowering, or even overclocking) the CPU frequency on a laptop? How can I do it in Ubuntu and will it increase my battery life (as I never play games and stuff)  And do fan speed and CPU frequency have any correlation?

I'm having a problem with Windows 7 64-bit. I thought it was slow and all, but then I saw that the CPU usage was always around 80% and started searching for a solution.  There are two svchost.exe's consuming around 30% each and in the resources monitor there's a system interrupts consuming 45% all the time. I tried closing the applications, but it makes no difference.  I tried some other things that I've found on Google, like disable system updates, but it didn't work.  I don't know if it will help but here's my specifications:  Core 2 Duo 4400 ATI Radeon 4850 4 GB DDR2 RAM     EDIT  I ran the suggested program and got this information; did I get it right?      EDIT  As you asked here it is, did I get it right now? The other TCP/IP there's nothing.    EDIT  I ran msconfig and took the services that one of the svchost.exe processes was using out of the startup and now my CPU is around 50%, but I still would like to improve it further. I can't lose that much CPU power just because of Windows...    EDIT  Yeah, there's nothing I can do here. I am going to reinstall Windows&nbsp;XP soon, it's really weird...

Thanks to the help of a few of the other guys I have my AC to DC rectifier working, and the rest of the power supply working.  Now while testing the power supply, my 18V AC transformer gets rectified and put into my circuit below   And I end up with 1.3-26V DC output selectable via the pot R2.  Now while running this @12V with a LED strip light, running about 600mA my heat sink got quite hot. Not hot enough to cause the thermal protection in the LM317 to cut in but hot enough to get me thinking.  Power dissipated = (Vin - Vout)*Il = (26 - 12)*0.6 = 8.4W  My heat sink is rated at 11 C/W and I pasted the LM317(TO-220) on.  Max C/W is = (MaxRunningTemp - ambientTemp) / power = (60-25)/8.4 = 4.2 C/W  Does that sound right, never done any heat sink calculations before. So I would need a heat sink rated at &lt;4.2 C/W  I would not see my self running this over 500mA again but running this circuit at 5V would change a lot? The power dissipated would be 42W if 5V @ 500mA. What can I do to prevent needing a HUGE heatsink? and are my calculations above correct?

I run distributed computing projects, which typically want to use 100% of the CPU.  How do I limit the CPU usage in terms of temperature instead of percent usage?  Also, what is the maximum safe temperature to keep an Intel i5 running 24/7?  (With no CPU limit FahCore_a4 causes this machine to run at 82 degrees Celsius.)

I'm trying to control the fan speed of my MSI GS60-2PC laptop on Ubuntu 16.04. But pwmconfig reports that There are no pwm-capable sensors modules installed  I'm pretty sure these fans can be controlled, because some utilies on Windows can control them. What I've done  I've run sensors-detect (as root) like this:  yes | sensors-detect    It seems to only detect &quot;coretemp&quot;. .  Then pwmconfig (as root): pwmconfig    And  There are no pwm-capable sensors modules installed.  I've tried the following things, which didn't work:  Adding to grub (and then rebooting): acpi_osi=Linux Adding to grub (and then rebooting): acpi_osi=!Windows 2012 Adding to grub (and then rebooting): acpi_enforce_resources=lax    What I get when I run the sensors command acpitz-virtual-0 Adapter: Virtual device temp1:        +27.8°C  (crit = +105.0°C) temp2:        +29.8°C  (crit = +105.0°C) temp3:        +50.0°C  (crit = +100.0°C)  coretemp-isa-0000 Adapter: ISA adapter Physical id 0:  +48.0°C  (high = +84.0°C, crit = +100.0°C) Core 0:         +48.0°C  (high = +84.0°C, crit = +100.0°C) Core 1:         +44.0°C  (high = +84.0°C, crit = +100.0°C) Core 2:         +46.0°C  (high = +84.0°C, crit = +100.0°C) Core 3:         +44.0°C  (high = +84.0°C, crit = +100.0°C)  EDIT:

Problem  I installed Ubuntu 12.04 on a Dell Inspiron 15R. As soon as I boot, the fan starts at full speed and stays constantly on. I've seen similar posts, where installing fan control apps are recommended like  i8kmon   jupiter mesa-utils   but in general, these do not allow for automatic fan speed control and one has to manually set the fan speed, while keeping track of the processor's temperature.
