GPU temperatures in an M1330

i8kfangui says my GPU temperatures are between 46C and 49C.
CPUID Hardware Monitor says my GPU temperatures are between 69C and 71C.
This is not gaming. It's just typing and viewing files.

I was expecting i8kfangui to be a little off, but 23 degrees off?

The CPU temperatures are a lot closer, with CPUID showing both processors, the hottest one of which is around 6C hotter than what i8kfangui says. Nowhere near the difference in the GPU temperatures.

Which program is more reliable for GPU temperatures?

 

I'm using rivatuner and with light processing or surfing, the GPU temps are registering as mid to high 50's C with an ambient temperature in the room at around 70. I find it pretty reliable. I guess I'd try rivatuner and see if CPUID is closer to the truth or is I8kfangui more accurate. 23 degrees is a big difference...yikes!!

 

@chelet: i8kfangui needs to be tweeked according to a thread here in dell forum.

@callanish: In rivatuner, my idle temperatures are 10 degrees higher with latest drivers than with the ones from windows update. What drivers are u using?

 

Here ya go.

Somehow I don't think that adding 3 to the GPU temperature and 2 to the CPU temperature is going to account for that 23 degree difference in GPU temperature that CPUID shows. If the difference were 3 or even 8 degrees I wouldn't be so surprised. But 23 degrees? I certainly hope it's CPUID that's wrong.
My room temperatures are around 70F (20C).
I'll check out Riva Tuner.

 

ATITool, Everest, and Rivatuner reads the same GPU temp.

My tip gives a way to match it 100% on the I8kfan.

It seems clear that you didn't read it through, so go ahead and read it through. I don't think I typed anything about adding 3 to GPU temp, but did mention changing sensor reader to it.

 

ACHlLLES' instruction work fine. You might need to offset the gpu temp by +10 degrees depending on the drivers. At least in my case.

 

Sorry for the late reply.

167.45. I've tried the drivers from Dell and some of the drivers from laptop2go and keep coming back to the 167.45 for performance and the fact that it registers 10C cooler while idling than pretty much every other driver I've tried.

 

Same here, using the 167.45 as well, performance is okay (not as good as the latest 174.74 or 175.12 i think, but otherwise my gpu runs up to 104°C and downclocks when gaming). I use nTune to monitor temps and do no overclock.

 

I did that, and it reads only 2 degrees C higher than before for the CPU and 3 degrees C higher than before for the GPU.

I've installed Riva Tuner and it agrees closely with CPUID, sometimes a degree different, but usually exactly the same.

When i8kfangui (with the 3 added) read 50C, Riva Tuner and CPUID read 70C.

A couple of minutes later, after the fan has come on and gone off, CPUID and Riva Tuner are reading 68C while i8kfangui reads 48C. By default the fan seems to come on when the temperature gets higher than 70C.

This is when I'm doing nothing more than typing into the computer and using ethernet.
Is it normal for the card to get this hot when not under stress? And is i8kfangui not accurate for a GPU with GDDR3 unless you use an offset of over 20C?

I tried CPUID, Riva Tuner, and i8kfangui with my 1720. CPUID and Riva Tuner agree and i8kfangui only needs a 7C offset to match them. The 8600M GT in the 1720 is a GDDR2 card though.

My driver for both cards is 7.15.11.7431 from Dell, dated 2/22/2008 (according to Device Manager). I'm concerned that the 8400M GS in the M1330 is going to burn itself out and start getting the vertical line thing in 2 or 3 months. What is a safe temperature for it? I have 2 more days to decide if I want to return the laptop.

 

For the second time, my guide to CHANGE THE TEMP READING SENSOR to #3, not offsetting the temp by 3C.

If you did what I wrote, the temps will not have such difference. (your quote "When i8kfangui (with the 3 added) read 50C, Riva Tuner and CPUID read 70C")

Just check my pics out. I8kfan temp is same as ATITool.

 

Sorry but that doesn't do it either. Still showing 10C less for GPU temperatures with i8fangui than with CPUID and RivaTuner. And 5C less for CPU temperatures with i8fangui than with CPUID.

 

Thanks, I'll try out the 167.45 drivers.
