HeatSink Compound Question.

I have been using Radio Shack brand heatsink compound for about 2 years now. (same tube I bought back then) they have apparently changed the mixture and/or make of it and still list it as being the same stuff. I bought some recently and I really don?t like the way it looks, feels, and spreads. It is like a gel almost and is more cohesive to it?s self then the surface. The old compound I use to use was like a paste and worked very well. I haven?t actually tried using this new compound to see if it will actually help cool. My last project, which I almost did not have enough to finish with the old compound, was too expensive to use as a test for heat transfer. Plus I am not familiar with the expected and normal heat ranges with my last project.

Now on to the question? Are there any local stores that would carry heatsink compound, not glue, like the old Radio Shack brand? By local stores I mean electronic stores, best buy, I have already exhausted all the computer shops I can find with in an 80 mile radius. For some reason they only have the thermal glue. :( I am just looking for closer and local alternatives than order off of the internet. Just name something local to you. I will find it if it is near me. :)

Failing that. Can someone recommend a good compound by name or shop brand that isn?t over priced? I don?t do a lot of over clocking but sometimes I do. I just don?t like settling for the thermal pads that come on heatsinks plus after you remove it once or twice it isn?t really very helpful.

I know of ArticSilver brand but last I checked it was a bit pricey for little difference it showed in tests.

Guess that is it. If I confused you let me know and I will try to undo it. :)

Thanks.

humm... didn't know there was an articsilver 3 now. test results do show to be better. comparing to what i do know about my Raido Shack brand compund it probably would be worth the extra 3 to4 dollars.. wonder if i can find a local shop that sells it so i will not get hammered on shipping..

I don't know about a local shop. Arctic Silver has a listing of dealers on their Web page.

You will probably be nailed by the shipping charge...

damn. i was about to buy some and right at the botom i read.

"Caution: We do not recommend using Arctic Silver 3 on Intel Xeon processors. The huge contact area and large gaps between the processor and the heatsink require a thermal pad or thick mesh-reinforced paste."

why is articsilver 3 not good enought for this? the reason i ask is because i have xeons and wan't to remove the heatsink to copy down numbers i had befoer and lost. sure it will work fer everything elsei have but if it will not work for my xeons i still need something for them. any sugestions?

edit.. ok i just noticed the articsilver 2 and the Alumina don't have the warning about the xeon. but i would still like to know why AS3 has the warning if anyone knows.
thanks.

The warning is there for all three Arctic Silver thermal compounds. It only applies to the older Xeons with about eight square inches of contact area. The surface of the HS supplied by Intel is so distorted that a mesh reinforced thermal is recommended. With that much surface area, thermal transfer is not a big issue any way. I should also note that excellent results have been reported with the current P4 based Xeon and Artic Silver thermal compounds.

This warning probably refers to the viscosity profile of the AS3. Since there is a big gap the AS3 might flow at the elevated temperatures and leave voids... not good.

I am not sure if it is the kind you want, but I saw that MY local Best Buy DOES have thermal compound. It is made by Antec. I think it was $4. Have you seen it?
