Hello everyone,
I've been having a ton of trouble with various types of throttling on my Lenovo T480. It's mainly used for work so I dont expect to properly game on it but I do like to play the occasional cs:go match or some wow classic dungeons when I'm travelling with it.
So long story short my inital toruble were mostly related to power limit throttling but by undervolting the CPU & raising the power max values in Throttlestop's TPL I seem to have gotten rid of this. At least I no longer see and TDP throttling which is nice.
However I played around some more because the cooling on this laptop is horrendous so any game (even 10-15yr old ones) would just super quickly skyrocket the CPU to over 80C and it would throttle down to 400mhz.
So my current setup is the following. TPFan control is installed and set to put fan at max speed as low as 60C to keep the CPU temp below the 80's when playing. It mostly works and when it reaches 80 TPFan just put the fan at emergency speed and quickyl cools it down in a minute or so. To achieve this I have locked my CPU to not boos over 2.3ghz because it would otherwise boot to 4.2 when playing 15yr old games which run just as good at 2ghz. Thus creating a ton of temp for no reason at all. With this setup everything was working fine. My BIOS is the latest version available from Lenovo as there was a recent fix released because their laptops would severely thottle both CPU & GPU when either hit ~70C. Nvidia control pannel has any possible settings to max performance as well.
My problem right now is that without any changes to the throttlestop settings, nvidia settings, no updates installed and laptop cleaned as recently as last week. The darn thing absolutely randomly Thermal throttles at 50-60C and goes all the way down to 400mhz. I have attached the log file that it generated and also screens from my home page, FIVR and TPL settings in the hope that someone has had similar problems and can suggest why this is throttling at below 60c. Weird thing is that even now I can sometime put in a 6hr session playing with no fps drops and zero throttling. But most of the time as soon as we hit 60c it goes down to 1ghz and then to 400mhz.
Any suggestions are highly apprecited.
PS: Lenovo Intelligent Thermal Solution is turned off, drives uninstalled because I read on a couple lenovo forums that this heavily limits CPU performance. Though keeeping it off did seem to margianlly improve things I woul say it didnt change anything overall.
Specs of the laptop are:
i7 8650U
32GB RAM
Nvidia MX150 GPU
BOIS version: N24ET59W (1.32) from June 2nd 2020
