Heatsink Compound: On core or on heatsink?

[SimeonArt]

I was just wondering what surface in was best to apply the artic silver. should i spread it on the bottom of the heatsink or on top of the core? I've seen it done both ways but was wondering which is the best or if it really matters. thanks.

core.

Definitively CORE!

Core.....Paper thin layer....

Core... The rule of thumb is to put on whichever surface is smaller. In the case of CPU's this is normally the core.

thanks for the info everyone

FWIW, I put a razor-thin layer on the core, plus another razor-thin layer on the applicable section of the HS. Seemed to give good results...

I just installed a Pep66u/Delta. The instructions say "1mm" of spacing between heatsink and chip. So I put a bunch of RS heat compound on the chip and slapped on the Pep. Is this the right way to do it? I thought the idea was for direct metal/metal contact w/the compound taking up the air bubbles.

I have a question on this-----------I put some Radio Shack heat sink compound (Silicone Based ) between my Thunderbird 800 and the heatsink and it has done wonders ---temp came down 10 Degrees C. The question is on the CPU I avoided putting and on the diode thingys and the little metal gates that are exposed on the top of the chip. Does it matter if you put it on the whole CPU or just around the edges. I don't want to screw it up.Another thing ---the heat sink compund is SILICONE based ---does that matter? And what is the difference between Artic Silver and a cheapo Radio Shack Silicone base heat sink compound ? Is it just harder to get off if you want to remove the stuff from the CPU ??


Waiting patiently for your replies,

only on the Cpu core... you don't need compound for the bridges or anything else...

Thanks for your reply. I just ordered some Artic Silver so I will use this Silicone based paste until then. I was running aroung 50 C and close to 60 C with a reasonable load and was having heat problems---Blue screen etc.. -------Just with the silicone based paste I was able to lower that to 40 c and about 44 c with a reasonable load. So I was quite pleased with just the silicone based paste so I can't wait for the Artic Silver.




BTW I have a Thunderbird 800 and an Asus A7V mobo for those interested in the heat generated.

Thanks again,

Dave
