Advice needed - i7 965 and Arctic Silver 5

Vector

I have never used AS5 successfully. So I just have to ask again how to apply this stuff. The Intel cooler has some gray sticky crap (geez) which I assume must come off to use the AS5. I went to the AS5 website and found instructions for different types of cpus but none for this 965. I am not sure which direction to apply a line of AS5. The AS5 website does state that a little line is all ya need and not to spread it, let the AS5 squish around when putting on the cooler.

Advice appreciated?

Thanks.

I would recommend using Ceramique instead. I've had better luck with silicone based TIM than I have with AS5. I've used silicone TIM, AS3, AS5, Ceramique, MX-1, MX-2, thermal pads and some cheap "silver thermal compound" that the local shop sells...which is basically the original AS TIM. I've had the best luck with Ceramique and MX-1 (which is no longer being sold that I can find). Ceramique is a ceramic based thermal compound. Ceramic is a VERY good conductor of heat. I've even had a few engineers recommend the ceramique over AS5...

I have read pros and cons about these product. Like don't get the AS5 on any electronic components because of the metal particles in it, and with Ceramique it's very hard to spread around.

AS5 application instructions for an Intel quad: http://www.arcticsilver.com/pdf/appi..._quad_wcap.pdf

The Core i7 die is positioned running the other way under the IHS though, so instead of applying the AS5 horizontally you need to do it vertically.

This CPU came with the worst cooler I have ever seen in twelve years. The base copper area is rough and marked up and scuffed. Not sure if lapping it will help. I think I will have to get a Thermalright 1366 RT cooler.

$1,000 cpu comes with a p-o-s cooler.

Your Amazing Intel!

i have been able to use AS5 on almost everything perfectly... including my laptops!!

dont really know what you mean by unsuccessful. just apply a thin even coat across the CPU.(lol )

AS5 = arctic silver 5, right?

Actually its a horizontal plane morbias when u rotate the cpu.

According to Arctic Silver the spreading technique is for small naked core(Thunderbird, chipset, etc...).

Now for Quad core CPU (C2Q - i7) they recommend a straight thin line of compound across the center of the chip with the triangle mark pointing down and to the left....Horizontally for a C2Q and vertically for an i7.

For my part i always used the rice grain technique (right in the center of the chip) since single core CPU (Heatspreader) to i7 and i never had any issue and no overheating.

Right now i'm running my i7 920 @ 3.5GHz, 1.25VCore with a Noctua NH-U12P full load (OCCT) around 55-60C which is to me pretty decent (rice grain technique).

Their technique highly reduce the risk of trapped air bubble between the chip and the HSF compared with the spreading technique.

If there's no SMT near the area you apply the compound there's no NEED to use Arctic Ceramique but you can always give it a try....I've been using it (Ceramique) for a while on everything and i've seen no significant difference with AS5.

Well yeah, if you rotate the cpu 90 degrees obviously you put the line the other way. The point is, i7 has its cores positioned differently to C2D.

Every since messing with an old P2 I have always applied a thin even layer across the heat spreader, it's not like this is rocket science. The CPU is underneath that huge metal plate on top and all the compound has to do is fill the micro unevenness/imperfections found on the cooler/heat spreader. Get something like MX-2 or that Diamond Compound, both of which perform great (33C Idle 48C Full Load (11 Hours of Orthos) w/ E8500@4.0ghz Tuniq Tower 120 + MX-2)

Thanks for that link....just installed a new Q9550 the other day and my temps have been a tad bit higher than I'd like to see (hit 73C under load, idling mid 50's)....guess I'll try AS's approach to applying my Ceramique

There is no difference between a heat spreader on a P3 and an i7. It's just a flat piece of metal, no special instruction for quads.

IHS isn't always flat...lol....seen some where center is low or high.

LedHed

that has nothing to do with the number of cores under the heat spreader, flat is a general term not an exact..lol..

"flat" makes a difference in how the TIM spreads when the heatsink is installed. First installed....my ceramique all spread to the outside. Strange occurance for me as I've never seen it happen and didn't think it was possible....processor and heatsink mating surfaces were nice and shiny...no signs of TIM showing on either..lol

just aply 1 drop spread it with finger.
put cooler on top off it.
and done pretty simple actualy ;>.

ofc i would't use to much remember silver is conductive and that you dont want it to touch other parts other then the ihs it self.

Funnily they use ceramic plates on the spaceshuttles as a heat isolater and spreader Oo

Using a thermalpaste containing some kind of conducting metal makes the most sense really, high silver halts most preferably since you don't want the material to hold heat ( like copper ) but to conduct it towards the copper/aluminum spreaders.

Ah well I donno, think that ceramique stuff sounds wierd

http://www.arcticsilver.com/ins_rout...2intelas5.html CHOOSE QUAD CORE .. QUAD CORES USE AC5 LEFT TO RIGHT ON CPU OR LINE LEFT TO RIGHT OR RIGHT TO LEFT LOL(MIDDLE OF CPU). CORE 2 DUO IS LINE TOP TO BOTTOM OR BOTTOM TO TOP . (MIDDLE OF CPU TOO)

Veteran

just apply a grain and a half across the cpu..flatten it out with the heatsink...dont lift the heat sink off or you will have air in there..easy

If you actually think about what you are going to do then its very easy

Well I use the AS5 and it works great. Cpu runs around 88F at idle.

Is that brown or white rice?

Personally I've had the best luck with tx-2 so far, I like the consistency. I just put a nice glob down and pushed some into my heatsink (I have a ccf). Works great for me. I'd like to try tx-3, but this stuff is expensive!
