I Just bought a new Heatsink which is the ZALMAN 9900MAX-B and I will be using Artic Silver 5 for my TIM. My CPU is the AMD 8core 8120

My question is, which is the best method to apply the thermal paste? I'm asking this because I've read that the paste needs to cover the area where the cores are and since my cpu has 8core I was wondering if it need more paste to cover more area or not, or just a small dab in the center will do like always?

I was just worried that the paste wouldnt be able to cover the whole CPU chip. Not sure if that makes a difference or not though..



Thanks for any advice1

Best method would be to follow this:

Also keep this in mind:

http://archive.benchmarkreviews.com/index.php?option=com_content&task=view&id=138&Itemid=1&limit=1&limitstart=5

Here is the Arctic Silver 5 recommended cure time instruction from the manufacturers web site:

Due to the unique shape and sizes of the particles in Arctic Silver 5's conductive matrix, it will take a up to 200 hours and several thermal cycles to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity. (This period will be longer in a system without a fan on the heatsink or with a low speed fan on the heatsink.) On systems measuring actual internal core temperatures via the CPU's internal diode, the measured temperature will often drop 2C to 5C over this "break-in" period. This break-in will occur during the normal use of the computer as long as the computer is turned off from time to time and the interface is allowed to cool to room temperature. Once the break-in is complete, the computer can be left on if desired.

So by my estimation of this statement it would take almost a year of normal use to properly cure the AC5 compound, or almost nine days of continuous power cycles to meet their recommendation. Benchmark Reviews feels that this is a characteristically unreasonable requirement for any TIM product, and we do not support it. We want products that perform without the burden of sacrifice on our time, especially with some many competing products offering performance without this extra requirement.

What I do is(after cleaning the crap out of both surfaces), put a dab in the middle and using a knife like tool(credit card or some other suitable tool) smear it over the entire surface of the cpu, you want a thin coat, not thick, just enough to still barely see the writing on top of the cpu, then following the instructions above, put the dabs as recommended in the instructions.

Edit: The link above was for intel chips, this is for AMD chips: http://www.arcticsilver.com/amd_application_method.html#

You never EVER want to do the 'Business Card' trick. You have a high chance of the paste spilling over into the CPU leads and causing over-heating issues due to air bubbles.

Here is an excellent video on how to apply thermal paste: http://www.youtube.com/watch?v=-hNgFNH7zhQ

Worst method ever, from testing it, seriously, like i wrote, do the AS5 method they have tested it and they ensure this is the best method...

PS: not the video, the Credit Card spreading method is the worse ^^

Yes, thank you! It is unbelievable at the naivety of people who think smearing paste on a CPU is the best method.

He has a lot of great videos. My favorite series is "The Tek" where he talks about news on technology and what's going on in the world. They have great humor and it is fun to watch. And your welcome, glad to help!

Maybe I have misunderstood you, but I have not heard of "tinting" the CPU.
