Temp Differences

Post by Dexter »

Hi All, well greetings from the Blue Mountains in hot and Sunny Australia (ATM), it's so hot ATM that I had to get a Zalman CPU Cooler a the crap CPU cooler that Intel supply nearly caused a meltdown of the CPU one night, The CPU was running at nearly 100% all night while I encoded some DVD files into mkv files, it left a rather nasty overheated electrical smell all day, it all seems OK now with no problems that I can detect visually or with the running of the system.

If anyone is interested I installed a Zalman CNPS9900 Max CPU cooler today and it immediately dropped the CPU temp by over 15c deg so quite happy with the result as it was quite warm outside today.

Anyway my question is this, when running Core Temp there is a large difference between CoreTemp and the software called Easytune 6 from Gigabyte, so which one is correct and how can you tell ?

Right ATM with the PC more or less sitting idle
CoreTemp is saying 33c-34c
Easytune is saying 24c-25c
9-10 watts

OK now I will start my encoding software - load of 98% - 100%
CoreTemp has Jumped to 46c-48c
Easytune has jumped to 39c-40c
56 watts

Here is my system:

Motherboard: Gigabyte, G1 Sniper M3
Bios: Version 6
Processor: Intel Core i5 2500, Sandy Bridge @ 3.30GHz
Socket: LGA1155
Technology: 32nm
Ram: 16G Kingston DDR III SDRam
AGP: Geforce GTX 660
Directx: Version 11

Thanks for your help :)

I assume that the reason for this difference is that Gigabyte's tool doesn't read the processor's core temperature and uses the motherboard sensor.
Core temperature is taken near the hottest spots in the CPU, therefore they are usually higher than what other sensors will read.
Therefore I would trust Core Temp's readings more than the motherboard manufacturers tools.

Thanks Mr Coolest

I suspected something like that, I tried a few of these types of Apps and yours is by far the best and most user friendly
Thanks for a great piece of software

I read in a post here somewhere that your machine idles around 40c deg and is around 80c deg at full load, that seems excessive to me
so those temps won't damage the CPU ??

I was looking at my CSV log from last night and it topped out at around 40c Deg at 95% - 100% load, so I'm happy with that
Cheers

80c is only under very heavy stress, and is still over 20c off tjmax, so it should be fine.
