AMD heatsink/Fan - Page 2

post #11 of 16
There has been a rumor floating around the internet that using Arctic Silver on an AMD processor voids the warranty on that chip. Well, one of our writers, DCFlux, set out to find out if that was, in fact, the truth. To do this, he went straight to the source and asked AMD.

AMD has directly confirmed that your warranty is void if you use any type of thermal grease other than Shin Estu G 749 (and even that is only for evaluation purposes). AMD also provides their reasoning for this rule.

Here is the exact email DCFlux received in from Steve Knauber of AMD in reply to his inquiry:
For permanent installation AMD only recommends using phase change material with the heatsink/fan. No thermal grease is recommended for anything other than temporary evaluation purposes. And the only thermal grease recommended for that is Shin Etsu G 749. Artic Silver is made up of a matrix with conductive particles. There is the possibility of creating electrical shorts on the package. Any failed processor used w/ Artic Silver or any other thermal grease other than Shin Estu G 749 would be subject to warranty voiding. The concerns with other thermal greases are due to thermal pumpout causing overheating with on off cycling of the PC over time. The above information assumes you are referring to use with Athlon. For Opteron Shin Etsu G 749 also is the only thermal grease recommended for permanent installation. Again the concern is due to pumpout with thermal cycling.
Obviously, the fact that you cannot use ANY thermal grease (other than Shin Etsu G 749) on AMD chips will make a lot of people unhappy and I can definitely identify personally. However, if you put on your thermal paste neatly, it should be easy to clean up if you have to send it back (not that I am promoting trickery).

However, while I have not confirmed this, it is quite possible that Arctic Silver's new Ceramique compound might fit the bill despite it not being exactly the same as conventional phase change pads.

And if it does crap out, clean it up well, AND KEEP THE HEATSINK! i learned the hardway!

I would recomend the new 4 pipe stock AMD 64 cooler. It's very easy to install and compares nicely to Thermalright XP-90. Not to mention you can install a High CFM fan for even better performance.

what is this about the stock cooler? is it really anybetter than these others? like the thermaltakes and stuff? if so, is it cheaper? i need it to work really well, but i don't want to spend too much, ya know? i think 55 dollars is my max, maybe a little more, if i can tell the difference. where can i find this new stock cooler from amd and where can i find all of the thermaltakes?


okay, at stock, well kinda, my fan keeps my cpu under 40C with 100% load for hours at a time. do i need a cpu fan or should i wait until i start overclocking? and with a 1800mhz proc i only want to up it to about 2ghz-2.2ghz, not too overly much, will i need a new fan? and another thing, what are okay system temps? i can keep my proc under 40C with load and around 32C idle. and my mobo stays around 35~36C but i have three case fans going at it. i just need to know what i should worry about and what i shouldn't.
