Arctic Silver 5 -- AMD NOT Recommended

DeusExMachina · 03-29-2006, 05:39 AM

Posted this in the Mod/PSU forum, and while searching for more info on Shin Etsu found this tidbit of useful info, and thought it's best to post here for a heads up...

Something AMD folks should be reminded of -- AMD doesn't recommend Arctic Silver 5...

Quote:

As for the Arctic Silver 5, AMD says don't use it. "Phase-change materials develop high adhesion forces between the heatsink and processor when the material is in the solid phase. This strong adhesive force may cause the processor to stick to the heatsink. During heatsink removal, this strong adhesive force may cause the processor to be removed from the socket while it is locked, and this action may result in damage to the socket or to the processor pins."

From post #9 (someone emailed AMD over the issue)...

Hello

Thank you for contacting AMD's Technical Service Center.

The thermal interface material that is installed on the bottom of the heatsink/fans included with the boxed sets is in fact 'thermal grease'. The grease may appear to look similar to that of a 'thermal pad', however, it is definitely thermal grease.

I have included the part numbers below and manufacturer information for your review which are the standard thermal grease applied to the heatsinks:

MANUFACTURER PRODUCT
Bergquist TIC-3000 Grease
Shin Etsu G751 Grease
Shin Etsu X23-7762 Grease
Shin Etsu X23-7783D Grease
Thermoset, Lord CPD TC-350 Grease

Hope this helps. If you have any other questions, please feel free to contact me.

Regards,"

For those not aware since Shin Etsu isn't as popular as Arctic Silver (and because Shin Etsu is harder find), it cools at least or better than Arctic Silver. So there's no performance decline in using it. It is more expensive, like $7 or so per application, but it goes on like butter and isn't as messy as Arctic Silver. It's also less conductive (not totally non conductive, less).

I have tested Shin Etsu, the stuff that most heatsinks ship with and AS5, and all are within the percent error. Although I do agree AS5 is way to adhesive. It has pulled my 3.2C out of the socket every single time:eek: . I myself would not recommend AS5 for any PGA processor, but there really aren't any other alternatives.

I've never had a problem with AS5. I just make sure that I run the computer for a few minutes. If I don't have time to wait, I just make sure that I slowly twist it free not just yank it out!

I assume this isn't too much of an issue with an LGA socket. It pays to be cautious in any scenario of course, anyway.

Definitely, a little heat before removal and I have never had a problem. In the past, I did pull a 2.4b out of a P4PE removing the sink. Amazingly enough, no damage. I'm not sure how good the Shin Etsu but I'll stick to my AS5 and Ceramique. Good info though.

From my test, that I did, the Shin Etsu performed slightly better than AS5.

No LGA is not really affected my the adhesiveness as the processor is held down by the motherboard, so unless you break the motherboard or retension mechanism the proc will not come out.

I've used this at one time just as an experiment in the lab. I used it on GPU and CPU's in place of heatsink grease. Its like silly putty, DAP FUN-TAK.
Have a look

see here:*From Skulls laboratory*

Eldonko · 03-31-2006, 08:56 PM

Ive used only AS5 and ceramique for years, works fine. All you have to do to not yank the CPU is twist the HS a few times to loosen the goop's grip.

Is that the same as the Blu-Tack sold in Australia?

BINGO!!! I wouldn't do it any other way. I even run something very processor intensive for a few minutes - maybe prime or something.

I have coolermaster Premium, and on the sticker its stated: Thermal compound by ShinEtsu, so can i be sure its the real shinetsu?

Is it normal that its difficult to apply, and AS5 not?

Greetings

If it's an old tube (like 2 years or older), there's a chance that it isn't what the label stated. Remember reading that one hardware site had it metallurgy tested, and found out the actual compound wasn't what was on the label. Coolermaster wrote back shocked of the finding and promised to investigate what occurred.

Edit: It wasn't CoolerMaster, but OCZ...

But the CoolerMaster version of Shin Etsu isn't the same as the straight Shin Etsu compound (it's made to CoolerMaster specs)...

Please stay away from the CoolerMaster Shin-Etsu, it is a blend of compound they designed for themselves and it does not work near as well as the Shin-Etsu G751.

It sure sounds like the same thing as Fun-Tak. I'll have to get some sometime and give er a try.
