Hi. I have an A8V, with a 3500 CPU. I recently took off the old thermal paste that comes stock with the Heatsink, and added sum Arctiv Silver 5. My temps seem to be at least 5 degrees hotter! Is there anything that I could have done wrong?

Someone pleae help, thanks
 
It might help if you told us which heatsink you're using. Are you using the stock heatsink that ships with retail Athlon 64s?

How much AS5 did you use?

Did you follow the application instructions on the Arctic Silver website?
 
Ok. I am using the Stock Heatsink. What I did, i just spread it over the whole cpu back, then got a credit card and evenly spread it out so it was a thin layer evenly spread over the whole CPU. I have heard that it could take a few days for it to settle in, maybe thats why. Another reason which I thought it could have been, is that in the same process, i changed the stock fan for a 80mm Fan that pulls roughly 28CFM. Is it possible that the stock fan is just much better?

Help appreciated.

THANKS!
 
Ok. I have read the instructions on the Arctic Silver Website, and it may appear that I have done it incorrectly.
 
yeah...no need to "smear" AS5 on the A64 processors. Just put a little "dab" on the center, and let the heatsink do the spreading. When you pull the heatsink off, it will look like a blob of oval, or circle paste in the center, with bare corners. I really don't know if this should cause a 5 degree difference though. The stuff that was on your heatsink (Shin Etsu) is pretty good stuff, so you probably shouldn't have messed with it, if it didn't really need it. After proper curing of AS5, it should drop a degree or two in roughly 2-3 days. I would also experiment with the stock fan, and the one that you switched it out with, to see which gives you better temperatures. I think the stock heatsinks actually do a pretty damn good job, if you're not overclocking.

It can cause temps to go up if the AS if "smeared" all over the top of the processor because the top is actually a heat spreader. The actual core of the processor is a lot smaller than the heat spreader and is located (naturally)in the center; under the heat spreader. If you spread AS all over the top of that, you are in fact insulating the unit and not allowing the spreader to distribute the heat. That is why they only want you to put a little dab in the center, where the HS meets the core.
 
Ok Guys, thanks for your replies. I followed the instructions on the AS5 website, and it now appears that my temperatures have dropped quite a bit from what they were before the way I had spread the AS5. I think I have realised now why the temperatures have gone up quite a bit as well though. The stock fan apparently pulls something like 38CFM, whilst the 80mm fan I replaced it with only does a maximum of 28CFM.
