So... maybe I was just a bit too much conservative on my AS5 application , or is it the fact that I might have made air buble in the AS5 while sreading it.

GAH, I had a 2 paragraph post responding here and the site crashed when I hit submit!!!

LMAO


Artic Silver does NOT recomend you spread it out when applying. They specifically state not to do that because it causes air bubbles as well as possibly causing gaps in the seal between the compound and the heatsink/CPU.

They state to place an amount roughly the size of a BB in the center, then press the heatsink down evenly, twisting slightly side to side. This forces air out and creats a seal.

What I do, and it is a pain and a little wasteful, but I find it more accurate.....is to follow those instructions, but don't tighten down the heatsink. Instead, immediatly pull it back off. Check how the compound spread. Did it get fully pressed out and spread across almost the whole CPU? Then you clean the heatsink and the cpu completely and re-apply, making any changes you deem needed based on the test. If it wasn't fully spread out because the heatsink wasn't seated, you may have to repeat this test until it IS fully spread. If it spread, but didn't cover the majority of the CPU then apply a little more this time. Then tighten it down and turn on the computer, check the temps in the BIOS, if it looks good, let it boot to windows and run some tests.


Also, as was mentioned, AS5 requires 200 hours of heat to cure. What I recommend is to let the computer idle for 24 hours. Let the CPU burn in, get comfortable. Then turn the system off for about 8 hours, let it cool completely down. Then turn it back on and load the CPU....either Prime95 or better yet, with Folding@home. Let it run at max temps (as long as those temps are safe, and watch for heat creep) for about 8 hours, then turn it off and let it cool for 8 hours. Finally, turn it back on and load the CPU again, check for heat creep (this is where it starts at a cetain temp under full load, but continues to gain a degree every so often. So it starts at 55c, 2 hours later it is at 57c, then 3 hours later it is at 59c) and let it run for at least 8, but no more than 24 hours. Then turn it off for 8 hours minimum and repeat that cycle for about 2 weeks.

Your AS5 should be fully cured and the system should run 3-5 degrees cooler than when you started

Sure......eventually. Like I said, 200 hours. My way cures it in 2 weeks.

How much do you use your computer on average? 6-8 hours a day? That'll cure it in about a month if you use it 8 hours every day. Also, it needs heat to cure........letting it just idle, or only putting a moderate load on the CPU for the 200 hours might not be enough heat, might take 250 or so, there's no way to be sure.

Me, I just like to dive in and get it done.

Thumper is right IMO about the as5, they say themselves that you don't spread it. I have the best results when I just follow how they say to do it.

Clean off your hs and cpu really good with some isopropyl alcohol. Put a very small "bb" sized dab right in the center, and you don't need much, really. If you see some squirting out the sides when you put on the hs, then you put too much. The weight of the hs spreads the as5 out, and gives you the best concentration of as5 where it's needed by far the most, the center. Nearly all of the heat coming from a cpu is coming from the very center of the cpu, where the core is.

One other reason I can see to do this as the instructions state, is that I have found myself from lapping my cpu's and heatsinks, that they're not always flat, sometimes by quite a bit. CPU's can be slighty concave, where the center may not touch the hs as tight as the corners and outer parts do. So then you have the center of the cpu, where like I said almost all the heat comes from, not touching as hard/well as the rest. Possibly a fix for this imperfection in the surfaces (unless you wanna start lapping) would possibly be to do as the instructions from as5 say (and who knows, could be one of the reasons why they say do the bb dab way). This way, from your as5 dab in the center, you are ensured a good concentration of as5 at the most critical place, the center.

Now I'm not saying guys spreading it are doing anything wrong, I just don't think it's the best way or necessary to do. The other thing I'd say is make absolutely sure your hs is making good contact with the cpu once it's seated, as already said. If something isn't on right, or on one side the hs is hitting on something pushing it up, you can get really screwed temps like yours.

I'm new to the site and forum and am quite glad I stumbled upon it, I've learned much here. I read this whole thread and just wanted to give you a little info on my temps as I just built a new machine on a P5WD2-P with a pressie. I used the P4 650, stock cooler scraped the factory thermal pad off and used AS5 the first time out. After the AS5 curing my temps were generally 45idle ~62C load. And I do mean load, some have mentioned F@H... I'm into other distributing computing projects utilizing the BOINC client so those were temps at 100% 24/7. Long story short... bought the Zalman 9500LED, used AS5. Now at a 4.3GHz OC my temps are 35/45C Just thought I'd chime in with temps as I couldn't believe the temps gg_Malkavian was having.

all i use is AS Ceramique. I burt out a 9600 pro w/AS5, stupid stuff actully does conduct.:swearing:ITS SILVER FOR CRYIN OUT LOUD! anyways I heard ASceramique actully out performs AS5 in the real world, besides i like it better and washes off easier too.
