Title: Qotom and the thermal paste...
Post by: kkoh on March 05, 2019, 04:09:46 pm
I'm just trying to get clarification... I took my Q355G4 apart and there is a "pad" that the aluminum heatsink rests against on the top of the case. Am I safe to assume that the pad stays put and that I should remove the heatsink, clean the residue that's there, and apply a pea sized drop of my Arctic Silver 5 to the i5 and reattach the heatsink?

Thanks,
K

Keep in mind, that Arctic Silver 5 is electro-conductive compound!
I can't see the CPU because of the heatsink, but if you have MX-4 it's safer choice.

I have Arctic Silver 5 and Ceramique 2

Ceramic 2 is an average. Take down the heatsink and see if there is close components exposed next to the CPU crystal die that may be shorted out if the Arctic Silver 5 is too much. And usual amout that is needed is about half to full rice bean. Pea sized sounds too much.

It's an i5-5200U. Pic of it with the heatsink off

And what do you mean that Ceramique is "an average"? It should also be non conductive nor capacitive so if there's a worry about other components a better choice, no? Also - not much around to worry about.

With the old stuff wiped off:

...also straight from the manufacturers website (http://www.arcticsilver.com/as5.htm)

Not Electrically Conductive Arctic Silver 5 was formulated to conduct heat, not electricity.

I put a thin line on the long chip and a little pea on the smaller one and reseated the aluminum heatsink and ran it with traffic flowing through all night last night.
CPU is 29.9c this morning. GPU is 27.9c
As this will be used at my house I think it'll be ok.  ;D

hm... Sorry for the conductivity. I also testing it with multimeter now...
"Made With 99.9% Pure Silver" made me suspitious. Obviously the silver in the paste is not so much.

Ceramic 2 is an average in thermal conductivity.

I'd guess they mean that the silver in the paste is 99.9% pure and not that the paste is 99.9% silver. But I can totally see how you'd read it that way.

Ah... I see how that would be confusing.
All set now. TY!

Those temps lower than they were before the new paste?

I'm getting a Q535G6, wondering if I should do the same.
I've currently got a Q190G4, which runs at 50ish.

Well they were a little misleading to begin with... I hadn't set the Misc. settings to use the Intel Core sensors so I'm not 100% sure where those numbers came from. When I set the thremal sensor setting properly the Cores (4 of them) report in the 45c-47c range. I can't really say if it made a difference as I didn't do any extensive testing before redoing it.  I can say that it seemed to me, at least on my unit, they did a decent application of paste, I just don't know what they used.
