Quiet and Cool. Thermal paste replaced! 38@idle 73@load

I replaced the thermal paste of the CPU and the GPU with "Coollaboratory liquid pro". And I replaced the thermal pad of the northbridge with "Arctic Silver 5" thermal paste.

Here are my sesults (in a 20 degrees Clesius enviroment, T9600, 2,8GHz, stock voltage):
73 dregrees Celsius at 100% load
(instead of 92)
39 dregrees Celsius at 0% load (fan off)
(instead of 45)

According to my research and different experiments this combination is my actual optimum.
The cooler and more silent system supports my usage of voice recognition (using the internal mic).
Of cause later the voltage could be reduced using rmclock (this is one of my next goals).

 

Nice results

 

I'm curious what other combinations have you tried and their results. I can't see there being much of a difference since rate of error in temps is pretty high using the built in thermistors (unless you have a laser temperature measurer). Did you not use the Liquid Pro on the Northbridge because it was aluminum?

 

I really doubt the results... a bit of paste isnt knocking 20 deg off your temps.

 

It looks reasonable to me. Remember he also replaced the cheapo thermal pad that Dell uses with quality paste. That will make a huge difference.

 

Thank you for the replies.

@sgogeta4
I used ik8fan and CPUID Hardware Monitor to check the temperature and different versions of cpu-z to check the frequencies. The temperatue values are consistent but not nessesary completly absult. IMHO at least the relative statement ist trustable.
I try to post some figures of i8kfanGUI here.

The upper figure is 'out of stock'. And the lower now includes also Rmclock undervolting. The white line changing from about 2% to 100% is the CPU load. The yellow ;-) line changing from about 25 to about 75 is the temperature. the maximum of 90 degrees is not in the figure - sorry, I did not took a screenshot of the maximum.
I think at least you can see the smaller Hysteresis marked with two ellipisis.

Maybe someone can post some i8kfanGUI figures from his original stock enviroment at idle-full load-idle?

This morning (CET) I additionaly installed RmClock. It supports up to 2,66 GHz with my T9600 and I changed the maxVID to 1,0375 and the minVID@SLFM to 0,95 (from 1,0). 100% load: 62 degrees Celsius at low fan (!) is the result. 57 dregees Celsius with high fan (enforced by ik8fanGUI). I can gladly show you this live via a free webex session next weekend.

Before I tried Arctic Silver at my old Latitude D (Pentium M 765) with quiet better results than the stock thermal paste. Some month later I found Liquid pro and was suprised, that it worked even better. This weekend I can look up the old results.

Here you can see, that Arctic Silver 5 is one of the best conventionel thermal pastes and that Coollaboratory Liquid pro has about 800% more thermal conductivity.


@tubby: Thank you for your trust.
@one4spl: Sorry you doubt the results.
Now with Rmclock@2,66GHz it is a huge 35 degree decrease instead of an 19 degree decrease, but maybe a webex session can convince you.

 

Yes the thermal paste results are plausible. The 20c temp loss isnt all because of the new paste. The method and paste they use on the stock unit is ineffective.

Try Undervolting your pentium M, they are the best chips to undervolt. Mine runs so cool, it literally has 0 fan usage.

Shin Etsu and Coolaboratory Liquid have replaced AS5 these days. Since Intel uses Shin Etsu for their benchmarks, im going to give them a go next.

Also keep in mind Coolaboratory Liquid PRO should NOT be used on aluminum heatsinks, it will react and corrode it.

 

@flipfire: Thank you for your plausibility statement with your high reputation power.
Yes, the fact, that Coollaboratory only works with copper was the reason I used Arctic Silver 5 for the northbridge.

Another user of this board "ofelas" told me, that he just bought Coolaboratory Liquid PRO for his notebook (M4400/Mobile Quad Core Extreme QX9300, Quadro 770M). Maybe he can post some of his results.

Coollaboratory becomes even a bit better over time (48h)

Sorry folks for my bad English. My German is better (but my French is worse) ;-)

 

It was on Heinz's suggestion (after emailing me a few days back with his excellent results using Liquid Pro) that I ordered a syringe of Liquid Pro.
It's not here yet, but will post results after I get it in & use it.
My results may not be as drastic, as I've already replaced the factory goop with the excellent OCZ Freeze thermal paste.
I'll beusing the CL Liquid Pro on the CPU & GPU heatsinks as they're both copper, and most likely will be doing a copper mod on the Northbridge - I've got various copper shims of different thicknesses to play around with.
Good work Heinz!

 

Hey, could you maybe post a guide for this? I have a tube of Artic Silver laying about, you think that would make difference just using that?
