Reasons for an overheating laptop

  • Blocked vents
  • Dried/pumped out thermal paste
  • Design Flaws
  • Non replacement of thermal pads along with thermal paste

We have already discussed about maintenance of laptops in https://www.desidime.com/discussions/laptop-buy.... Now, if the problem still persists then we can undervolt the laptop’s processor. It can be done in multiple ways. We will not do the hard way. Specialized software like MSI Afterburner, intel extreme tuning utility and Throttlestop make it easy for PC/Laptop enthusiast to either overclock/underclock their processor without damaging the circuits. Just restart the machine and your unstable system will revert to its stable self. 🙂🙂🙂 We will discuss about Throttlestop. 

Undervolting

A processor is overheating. Clearly it is wasting power. So, if we limit the power supply then we might be able to reduce the heating. It can be temporarily employed in software level by the use of Dynamic voltage scaling. Check this article https://en.wikipedia.org/wiki/Dynamic_voltage_s... for further knowledge.

Risks 

  • Unstable system. Random errors might arise. Solution is to close the application and restart the device.  
  • It can alter the system performance/damage if not used properly.

Throttlestop

App can be downloaded from https://www.techpowerup.com/download/techpoweru...;

The interface looks like below.

Processor used it an Intel core i7-9750H. It used to run pretty hot. After replacing the thermal pads and thermal paste I had to undervolt it. It runs cooler now.

After.*

Obviously I am not stressing the system. I am against frequent benchmarking of the system.

It has a benchmarking tool inbuilt.

Control Panel to do the actual stuff.

There is an option to minimize on close.

Glossary

  • BD Prochot (Bidirectional Processor Hot). If CPU gets hot then it has internal mechanism to protect the voltage regulators by utilizing lower multipliers. Lower multiplier will allow CPU to get so called Thermally Throttled. CPU gets slowed down. https://shauncassells.wordpress.com/2020/02/29/.... , 
  • FIVR (Fully Integrated Voltage Regulators)
  • Offset Voltage The voltage you want to deduct(undervolting)/add from normal operating voltage. It is in millivolts
  • VCCin and ICCmax CPU voltage and maximum current 
  • Turbo Ratio Limits Numbers. We need to use lower numbers. It ll limit the Turbo Boost power consumption.
  • VID Voltage Identifiers
  • CLR Resets the data

Please do your due research before doing anything. I will not be responsible for any damages done.

After the Plundervolt vulnerability Intel had issued patches to disable undervolting which can’t be reverted in some systems by OEMs like Dell. Also if I am not wrong it no longer works in 11th gen. and later. Only the traditional BIOS/UEFI based one.

However, beta 9.4.3 works for Intel 12th Gen Alder Lake Desktop and Mobile CPUs has been just released as of 01/31/2022.

I have not personally tried.

A small suggestion: always do such tests/tweaking first on mains/AC power instead of laptop battery power.

The engineer part of my brain somehow unable to accept this. If the processor is overheating, address the root cause what so ever it may be. Undervolting has its own cons, and on top of which if some half-knowledge person picks this process, we can’t really predict the mess.

Just a 0.11V undervolt in my i5 8250U ensures that the fan almost never turns on or at least isn’t audible in case of mundane workloads like video playback or web browsing. Otherwise the fan is noticeably more active.

right bhai. If Steps like changing thermal paste n pads, unclogging vents n dusting heat sink are taken then one has to look for other issues. Then one has to look if the problem is common. In my case the problem was common. I asked the Lenovo service centre. They replaced the heat sink module. Things didn’t improve.  And Core i7 9750H is very notorious for thermal throttling issues. I ll admit the usage of wrong words. 🙂🙂🙂 I am using Gelid GC Extreme thermal paste, Gelid GP Extreme pads.

Laptop motherboard is a tiny board. To diagnose it one ll need specialized equipments n skills. So, I took the matter into my own hands. 🙂🐒

disable intel turbo boost and run it on base clock, cool and fast 😄
