Monitoring temps m15x?!?

I just can't figure out this temp monitoring business. I have now fired up HWmon, thermofan, rivatuner and RMclock and they all give DIFFERENT readings on the same things. None of them agrees on anything. CPU having the most radical differences from 37C (rmclock) to 43C (HWmon) to 55C (thermofan). The GPU is does not have that big of a gap showing 47C (rivatuner) 48C (HWmon) and then I can't quite figure out thermo fan but it gives off an internal reading og 44C and a skin temp of 51C. All temps are measured at idle. How can I know what to trust, and why are the gaps in readings so big in some instances?

 

i have this dilemma as well. for my notebook cooler test, i need accurate measuring tools... but what to do when three different tools give three different temps?

 

best tool out there is everest for this. there is a free trial version. compare other scores to everest to see which are most reliable.

 

how do you know everest is the most accurate? any tests etc. to back that up?

 

did you not ask him this in another thread?
i seem to recall the same statement made by stirfry and then the same rebuttal by you....

 

and i will continue to post that answer until it is countered by sound evidence, and not WAGs

 

-_- He keeps saying Everest but never posts a reason as to why it's the best...

 

i love everest. we use the corporate version on our PCs at work for software auditing (cheaply). I love it on my homebuilt desktop as well. its great that it shows so much info on the motherboard, ram, etc... as well as the temps on pretty much everything.

 

I'm sure it's good and ranks highly but we're looking for a reason to call the best. Same with the other temperature monitoring software.

 

I have currently tested everest, rivatuner and thermofan for the m15x. Here are my findings

1. Rivatuner and Everest gave me basically the same temps ( plus or minus 1 or 2 degrees )
2. Thermofan gives 2 temps for the GPU. Taking the average of the 2 temps given results in more or less the same temp readings as shown by Everest and Rivatuner

I believe the reason people do use Rivatuner more is because you can monitor your temperatures without haveing to alt tab back to windows.

Oh, and the reason I think stirfriedsushi says Everest is the best is because it can also monitor temps of the hard drive and CPU. Everest also has so many more extra features which are quite user friendly. I got to see that my Battery already had some wear % with Everest

 

That's actually good info. I think I'll give Everest a shot. Might as well, seeing as I already use Riva and TF.

 

I think we need to get technical to actually solve this. What we would need to know is what the model number is of the chip or sensor that is responsible for reporting the temps. We would need this info from the manufacturer and I have no idea how to obtain that. Then we would need some knowledge on how it actually reports the temperature (my guess is that it doesn't actually pump out the temp in celcius?). And then we would need some info on how those apps actually treats the info it is fead. One very real possibility here is that some of the apps think there is a different temp chip in there then it actually is, and even though they can access the data it outputs they apply the wrong logic to interpret the data and thus we get bad readings.

Of course if anyone has a better solution to how this can be proven then I'd love to hear it but I'm just not going to accept that app x is more accurate then app y because one person feels this way.

 

do you think that temp readings from the bios will be accurate enough. even though you cant test the temps when you stress it i guess you can test the idle temps.

 

Personally I like HWMonitor the best as it monitors the CPU / HD / Ram / GPU and that is what I base a lot of my temps off of. To each his own though, until we have proof we do not know which monitor is the best.

 

Just started using Everest and for some reason, there are some discrepancies in the CPU reporting. I keep getting CPU temperature jumps. One second, it'd be 46 and the next it'd jump to 52 then later back down to 46. Any ideas on why this might happen? These jumps are too sudden to be correct.

 

CPU load...

 

I am not a big fan of everest personally. I tried one of the included memory speed tests and after a few run throughs I had gotten some very deviating results, everything from 86 nano seconds to -6 nanoseconds. Yes, you read that right, negative 6 nano seconds, meaning that it had completed the task before I had initiated it. How can they even allow it to output that? But this is off topic.

What we do know is that the motherboard and CPU is fearly well known so the CPU temps should be very possible to figure out with a little bit of research.

 

possible to find out where each program samples the temps from (i.e. location on the board, cpu, gpu, etc...) ?

this could be a reason why each program differs as much as it does.
then again, i could be off my rocker...
