PM 7720 thermal throttling

Laptop idles at 47c, spikes to 100c during normal operations like updating Windows or even opening an application like Illustrator.

I replaced the thermal paste a few weeks ago with some good stuff because this laptop has been doing this for almost a year and a half and I got sick of it. Replacing the TIM did not help. I was going to use liquid metal but the heat sinks on this are raw copper, so no go.

This is the Xeon E3-1535 processor with a Quadro P4000.

Was wondering if anyone has experienced this kind of wild temp swings and thermal throttling.

Thanks

 

Did you clean up the fans and fins (radiators), Also how's the state of condition of thermal pads and do you have any crappy cheap paste, then try to check heatsink contact with it.

Umm you seem to have some misconception, aluminum heatsink is a no go.Copper's good so go time.

 

I build gaming computers regularly so yes, I know to clean fans, etc.
TIM added was Thermal Grizzly Kryonaut, so basically the best TIM made.
You can't use LM on bare copper, it'll eat it up within a year. It eats aluminum up in hours. Only nickel plated copper is advised for LM.

Gamers Nexus should be you go-to source for LM application techniques:

EDIT: I was actually looking for advice on the behaviors of the Xeon processors and if people have found them unstable temp-wise.

 

This is a 5 years old pure copper heatsink from Alienware 17 which survived Liquid metal


This a +3.5 years Clevo P870 heatsink in copper which has survived near 4 year with Liquid metal.



And the heatsink in my other and older Clevo W860 run exactly as the two other... http://forum.notebookreview.com/threads/clevo-overclockers-lounge.788975/page-450#post-10308981

A good advice... Always test it out yourself before you throw out claims/statements (same as we who have used Liquid metal in many, many years)... @Mr. Fox @Falkentyne @Ultra Male @Donald@HIDevolution

 

Oh and....regarding your comment that Kryonaut is the best..

@Papusan is correct. Liquid metal does not harm copper. I have also been using it for as long as he has (about 5 years) with no issues. Does it turn the copper silver in color where it makes contact with it? Yes. Does that matter? No. It is not harmful in any way.

Point of reference (where it started): Repasting with CooLaboratory Liquid Ultra, any tips before I start?

Still using it today on my copper surfaces. No regrets.

 

The copper silver color is what you all should aim after. If you can and have the time... Apply Liquid metal, let it be on heatsink a few days (running or outside the chassis), open up then clean of or rub in more Liquid metal into the copper heatsink.

 

Correct. It fills the pores in the copper with the liquid metal, improving the density of the contact surfaces and the ability to transfer heat more effectively.

Worrying about the color change can only be described as silly and irrelevant.

 

Yees. And the second application(or you add more after a few days) will let the liquid metal stay put a lot longer (almost no degradation - or reduce LM degradation). The way to go on heatsink with not the best fits.

 

On most pascal mobile systems I don't find LM to be beneficial to the GPU, maybe a 2-3c at best during normal synthetic stress test and long term gaming.

CPU is an entirely different story though.
