A burning question

Post by pkumar » Sat Mar 23, 2019 9:48 am

Hi all,
I used to run gauntlet matches in Arena on my Z570 laptop (i5-2410M CPU @ 2.30GHz). CPU usage would be 25% with single CPU
engines not pondering. Now I have installed "Core Temp". It shows core temperatures beyond 85 C when running a gauntlet
for more than 10 minutes at ambient temperature of 26 C. That is a rise of 60 C! At this point Core Temp activates sleep
mode. Operating with higher trip temperature may hasten the laptop's demise - many people consider 85 C as bad enough.
Seems I have fried the processor for quite some time. Cleaning and re-pasting of heat sink are needed which I plan to do myself
(never done before). What temperature rise is normal in new or cleaned non-gaming laptops under similar conditions? What
is your experience?

PS: If you install Core Temp then untick any bundled program.

According to Intel docs your CPU has an max of 100°C die temperature:

But from my own experience common laptops are simply not designed to run heavy load for a long time.

Start to update the bios. For me it worked very well. Initial bios default voltage was total setting were strange.

This is why I have a bunch of big desktops and servers full of fans.

Laptop def.

Half way between a mobile phone and a proper computer.

Hi,
I also use a laptop - usually reaching no more than 72-74°C at full CPU usage; but during hot summer time I use Battle Encoder Shirazé to throttle chess engines. A very efficient tool; can also be used to tune some emulators speed, or to save some CPU available for your own use while running a tournament in background... Much worth a try!
