V2000z CPU upgrade temperature quest...

Hi Everyone,

I have a quick question. I recently upgraded my Compaq V2410 from an ML-30 1.6ghz to the ML-37 2.0ghz. My problem is that I am getting two different temperature readings for the cpu. AMD Dash Board Demo is usually about 4 degress celsius higher than what RM Clock says (ie. RMClock will say 47 and AMD DB will say 51). If I am correct in assuming that the fan turns on at around 54 degrees, then the fan is following the AMD Dash temps. What is causing the different readings?

And another question, when I swaped CPU's I noticed the ATI gpu chip has a really thick thermal pad. Would it be advisable to remove it and use a paste?, or is there too much of a gap? (I just removed and cleaned the CPU pad and replaced it with some thermal paste)

Thanks in advance!

 

They probably read the temps from two different areas, one from the CPU and one from ACPI for example?

the gap might be an issue depending on how the heatsink/pipe is attached. is the thermal pad thicker than the one on the CPU?

 

The gap left by removing the thermal pad would probably be a problem. You could make a copper shim to fill the gap and glue it to the heatsink with Arctic Silver thermal adhesive. I don't think it's worth the effort though.

You could give Core Temp a try and see if it agrees with AMD's Dashboard.

 

I would try notebookhardwarecontrol.

I have found that while both that and the amd dashboard display the same temp, core temp and speedfan are all over the place.

So that makes me believe that nhc and amd dashboard are the correct ones.

 

But which one should I follow?, the RM clock temp or the AMD dash board? I just don't want my fan always turning on when it doesn't have too. I will try NHC when I get home, but what would make them out of sync?, is there two separate temps sensors?

Just to make things clear, I only removed the thin thermal pad on the CPU and replaced with Arctic Silver. I did NOT replace the one on the GPU, but should I? It's a really thick pad so I decided not too.

One more thing, my current temps are as follows:

RM Clock: IDLE - 45-47 degress celsius
Full Load - 58-62

AMD DB: IDLE - 50-52
Full Load 63-66

Do they look normal?

 

HP's BIOS is set to turn on the fan at about 54-55*C (the latest one). Undervolt the CPU (if you haven't done it already...62*C full load is good) and you won't have to worry about CPU temp. I use MobileMeter to measure my temps (cpu and hdd); recommended for this laptop.

If you are up to disembling the laptop again, maybe you could fix the GPU with some new paste. Yet, it's not a powerful GPU so it may not be that important.
