M4800 CPU Temps Folding @Home

Hello all,

I tried running Folding@Home on my machine. The CPU temps got up to around 80C. IM guessing its bad for these to run that hot. The CPU fans spin up shortly after starting folding with the software. Has/Does anyone else here run F@H on their M4800? Is there anything I can do to run it and brings temps down, like change how the fans spin up?

 

This temperature is normal for high load and will not damage your system. The CPU can run up into the high 90s.

You can install Dell Command Power Manager and adjust the thermal profile in there... I believe one of them is more aggressive with the fans.

 

I know that the CPU itself isnt in danger at those temps, however I have heard in other places that the board and other components around the CPU can be damaged by running at those temps. Is this true?

 

I use a box card or hdd case to lift up the machine so that the fans will have more air space to work with, or a laptop cooler. That being said my normal temp with HW monitor is about 46C in a tropical country with air conditioned on. It has gone up to 80C during instances of continuous indexing or photo editing but not for long periods < 1hour. I guess if ran for 24 hours with 80C could be a concern which I would use a desktop for it

 

I don't think that there's much truth to that... The high temperature from the CPU is highly localized at the CPU and heatsink interface. I've run my M6700 at max CPU for days on end (CPU running in the mid/high 80's) with no adverse effects.

 

great to know that, I shan't be too worried for the high temps now

 

CPU temperature is always high under load, 80°C is too common. 90°C can be seen sometimes. However if any of the core occasionally spikes up to >90°C and drop back very fast under common use, need to check the fan/fin for dust or bad contact of heatsink.

 

Temps are stable. They dont spike at all. Under light use they are almost always around 43c and only get up to 80C under heavy load.
