TEMP readings - what is HIGH ? Thermal paste to use?

2013-05-27, 5:00 AM

T60p 2613CTO  Win XP Sp3

 

So I eventually downloaded and installed TPFANCONTROL.  v062.

 

Now what?  :smileyhappy:

 

I have no idea if the temps reported are good or too high.  I just installed with whatever settings are "default". 

 

Is there a "TPFANCONTROL FOR DUMMIES" that explains the reported temps and the various settings?  The  ini file does not explain it simple enough for me!  :smileyembarrassed:

 

This is what readings I get:

 

1 cpu 54°C
2 aps 36°C
3 crd 34°C
4 gpu 77°C
5 no5 50°C
7 bat 30°C
9 bus 38°C
10 pci 46°C
11 pwr 46°C

Fan Control State  "Fan 7"  ////when rpm is lower it says "Fan 3".

 

Switch 77*C

 

Speed

changes from 3300 to 4400;  higher  especially when gpu went to 79*C.

 

Mode is   "Smart"   with a value of  "7".

 

Just before I installed TPFanControl,  I took the whole machine apart and vacuumed every nook & cranny.  Lots of lint inside.  Fan was running LOUD a lot,  mostly when any video or esp FLASH was running in my FireFow browser.  I tend to have many tabs open at once. 

 

Fan is MUCH quieter now.  Although the paste on the cpu(?) was mostly dried out.   What kind of paste should I get and where is a good place to buy it?

First of all, what ThinkPad are we discussing here?

 

As for the thermal paste, Arctic Silver which can be bought at your local Radio Shack or online at NewEgg.

Cheers,

Ooops!  Sorry,  I thought I typed the model!

 

T60p  2613CTO   Win XP SP3

 

Any idea where I can lookup what are proper temp readings?

 

And where I can find simpel instructions for TPfanControl?

Re: TEMP readings - what is HIGH ? Thermal paste to use?

Hi.

 

For what's it worth, I'll give you my opinion:

- First of all, TPFC reads actually the correct temps. In my experience (and quite often) I have used SpeedFan as a different application (quite powerful and useful). But SpeedFan always reported my gpu temp (for example) higher than what TPFC reported (as much as 10-20 C).

- For the thermal compound - buy & use ArcticSilver 5. It would not hurt replacing the Northbridge thermal pad, if there is any.

- Difference in temp readings between cpu and gpu should not be so great. I used to have a 5-10 degree hotter gpu compared with the cpu, as they share the same heatpipes / heatsink. At some point I tried my best to make sure that both heatsink plates (cpu & gpu) sit correctly and flat onto the die surfaces of the chips ... I used some empirical methods of checking the correct flatness but it worked. I now ran my laptop with a higher cpu temp (4-5 - 7 degree in average) than the gpu.

- the value of the temps greately depend on the CPU / GPU types (if the cpu enters low power mode when idle, if the gpu is discrete and also uses low power modes when idel etc.).

 

just as example, - do NOT take this as reference, because the systems are different, but see below my temps in almost idle desktop:

 

1 cpu 59°C
2 aps 43°C
3 crd 35°C
4 gpu 55°C
5 no5 30°C
7 bat 30°C
9 bus 38°C
10 pci 48°C
11 pwr 50°C

 

fan runs @ 3000rpm (fan 128), Bios setting in TPFC.

 

I hope this helps ..

Proper temp readings are what you're getting from TPFC.

 

I'd just let the programe run in its "smart" mode. That's what I do on my machines anyway, unless I'm doing something very stressful and switch to "manual".

Cheers,

George

Let me ask a different way.

What maximum temp levels are considered NOT too hot for gpu and cpu, in my T60p?

Even in Smart mode, there *could* be something mechanically wrong that causes the cpu temp to hit 100*C. The fan could spin at 5500rpm and still no temp drop. Switch to manual mode and yet the temp still stays over 100*C.

So : What maximum temp levels are considered NOT too hot for gpu and cpu, in my T60p?

Thanks! :-)

OK, 100 degrees - if we're talking in Celsius - is almost the shutdown point, and implies that there's something wrong on the hardware level, my guess would be that the fan is either dying or is not seated properly.

 

Your CPU idle should be under 60 and GPU under 65 in my experience, on a healthy ATi-based T60/p machine.

I am thinking that the thermal paste on my fan has dried out. It was kinda hard. I will buy new paste and see if I can get the temps lower.

I was using 100*C on cpu as a hypothetical problem. But while I am actively surfing the net (reading forums, news, email, facebook, maybe see a funny video clip) with a bunch of open tabs, my gpu has jumped from a usual 78*C to about 94*C. Vdeos and flash content seem to be the cuplrits.

I just replaced the fan on my T61 which was showing the odd fan error here and there and making noises like a lawn mower. Temp was ~ 90oC peak before the fix and it was pushing boiling hot air out - enough to make you move your hand away from the vent.

 

The entire HSF assembly was removed, air dusted, both CPU/GPU and fan surfaces cleaned down and polished with IPA and the actual fan unit removed and replaced with Kapton tape replacing the silver tape. Arctic silver was applied generously. Was fairly easy to replace.

 

Temp is now around 50oC peak and it's eerily silent most of the time which is good.

 

Hope this is of some use.
