HWMonitor not showing GPU temperature and usage

[smtrejo]

Hi,

When I run HWMonitor or SpeedFan, GPU's temperature isn't displayed, not even "0 C" (zero degrees). Does this means the GPU's temperature sensor is damaged? Or it doesn't has one?

Lately, my laptop fan started to work at minimum speed no matter if CPU reached temps above 90C. I read somewhere that in order to the fan to vary its revolutions it needs to "combine" temperatures from CPU, GPU and another element that I don't remember. I was guessing that maybe by the lack of GPU temperature reading the fan might stop working correctly.

My laptop is an old HP Pavilion DV7 1240us Turion X2 64 with ATI RADEON HD 3200.

Thanks in advance.

HWMonitor is generally only good for your CPU and base system. It's not very good with GPU's. Get MSI Afterburner and GPU-Z for GPU information.

not necesarily damaged, could be weird sensor and the apps doesn't know how to handle it so it doesn't show it

the 90°c is high, since this seems to be a old laptop, have you cleaned fan and heatsink? have you replaced the thermal paste on the cpu?

all the dv7, hps form that time work really hot so fan and heatsink and thermal paste maintenace after 10 years is a must

You are not seeing GPU temps because you do not have a separate graphics card. ATI RADEON HD 3200 is AMD's CPU onboard graphics.

To the OP: I use both CPU-Z and Afterburner and have noticed the temps between the two for my SLI 970s are exactly the same between MIN/AVG/MAX.

@bystander: I'll give GPU-Z a try later when I get home and post the results.

@atljfs: Sadly I've done almost everything possible, my first thread was about what I've done to make the fan work again . To lower the 90C+ temps I had to lift the laptops bottom wich it helped, but the fan problem persisted. Last weekend I build a DIY cooling pad with 12v fans, it reduced like 4-5C, but again, the fan still doesn't speed up. The only remaining thing to do is the thermal paste replacement as you suggest, to gain some more degrees to compensate the fan malfunction.

@10tacle: yeah, integrated graphics are very limited on their customization, there's very few things to do while I'm stuck in this old model.

Anyway, as a last resort, I'm considering to control the fan speeds via the DSDT table and there's also the option of using RW Everything to modify the ACPI table, a bit risky but I'm running out of solutions (until I get a new laptop or desktop).

Thank you guys

I don't think you understand - sorry I guess I wasn't clear. CPU-Z is only designed to read data from a dedicated GPU, not an integrated GPU on the CPU. CPU-Z can't read what's not there.

you can put alot of time, effort and oney but the dv series of hp laptops are a heat mess

they work like a heat blower

i think that you should consider to move away form this laptop, time to get a new one
