Arctic Silver 5 Problem

[thescreensavers]

I applied Arctic Silver 5 to my laptop cpu and followed the directions on AS website and In about 3 weeks I check on it. The thin layer is gone on the CPU core and 1/3 of the core was covered. I checked the base of the HS and there was just an outline of the CPU core of AS5. So now I re applied it. I made a thin layer on the cpu (turion) then very little on the HS and then smeared it all around the base of the HS(to fill cracks and stuff) and screwed it back up. The way the website said wore off Does this mean I need new AS5 and that the one I got has gone bad?

Dude, you're lucky you didn't fry your board! 😉

AS5 is different! You shouldn't smear it 'all around'...

Source: Application Instructions for Premium Silver Thermal Compound

For Arctic Silver 5:
Arctic Silver thermal compound should be kept away from electrical traces, pins, and leads. The compound is slightly capacitive and could cause problems if it bridged two close-proximity electrical paths.

Carefully apply the thermal compound directly to the core of the CPU...

Transfer about 1/2 the size of an uncooked grain of short-grain white rice or 1/4 of a BB for small core CPUs.

I know ppl who smear it also and it works fine. I made a mistake in my post lol ill fix it.

If you smear it around, it could leak out past the core, and short something out. This is a bad thing.

Leak out past the core wtf are u talking about? you mean onto the mobo? thats why I dont put a lot.

 

[VinDSL]

LoL! What we have here is failure to communicate...

First of all, you make it sound like you and your buds are laying AS5 on your CPUs like pancake batter squeezing out of a waffle iron -- then you make it sound like you're using it sparingly.

Which is it?

If all else fails, RTFM! 🙂

QFT

my impression was of the "waffle iron" analogy, where the paste was squeezed out from between core and heatsink onto the motherboard, where it might short something out

Use Ceramique. It's easier I think..

 

[Gautama2]

doesnt cermique like glue your heatsink to your cpu?

 

[lenjack]

no.

Correct! 😉

Source: Ceramique Application Instructions,

Ceramique is a grease, not an adhesive. It cannot be used to glue a heatsink to a chip.
To permanently glue a heatsink to a chip that does not have any other attachment method, please use Arctic Silver Adhesive or Arctic Alumina Adhesive.

You'll be better off to let the squishing do its work. It never gives problems to me in my own experience AFAIK

 

[firebyyrd]

do you use the squishing method with ceramique also?

What did the laptop originally have on the heatsink - thermal grease or a thermal pad?

I worked on a laptop that had a thick thermal pad on it. Without it, there was a gap of a little less than a millimeter between the core and the heatsink. A thermal paste layer would have been far too thick to effectively transfer heat. I cut a little square of copper sheeting and put ASII on both sides, and sandwiched that in between. Afterwards, the heatsink got hotter than ever before, indicating that this method was even more efficient than the thick thermal pad was.
