AS5 made it only 1,5ºC cooler?

Blito · Post by **Blito** » Thu Jul 15, 2004 6:45 pm

Hey, two days ago I finally adquired some as5 hoping to get =noise/+speed or >noise. But it was not the case.
It only dropped 1,5ºC max.
Could it be too much goop? Ive put only as much as they say, but still.
Could it be the V11?
Could it be the airflow on my case? (the cpu its horizontal, and it exhaust via the i/o panel and a fan above it)
I've already reinstalled the hsf twice, and tomorrow I'll probably be doing it again, this time putting the goop in the hsf with some tape to help.
But it's me or it's just so?

Thanks in advance

First, to what are you comparing the AS5? Also, from the AS5 webpage:

Important Reminder:
Due to the unique shape and sizes of the particles in Arctic Silver 5's conductive matrix, it will take a up to 200 hours and several thermal cycles to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity. (This period will be longer in a system without a fan on the heatsink or with a low speed fan on the heatsink.) On systems measuring actual internal core temperatures via the CPU's internal diode, the measured temperature will often drop 2C to 5C over this "break-in" period. This break-in will occur during the normal use of the computer as long as the computer is turned off from time to time and the interface is allowed to cool to room temperature. Once the break-in is complete, the computer can be left on if desired.

Also, I believe people sometimes expect too much of a drop from using ASV versus a generic thermal paste, or AS Ceramique. There are alot of other factors that affect how hot your CPU temperature is than just thermal paste, while in your case it seems to have helped, I'd try fiddiling around with some other things first, see if that helps. And if it comes down to it, I'd reapply, but only if you've tried almost everything else you can think of to make your temps lower. Try taking your side panel off and see how much your temps drop, if they drop too much it may be because your intake is not sufficient. Just throwing out some ideas for ya.

I'm comparing it to "Silmore", the white stuff that came with my V11.
Reading Dan and others, I know that the temp drops should not be anything super, but one can only hope to get that "10ºC drop" too

Without the side panel it only gets, just as before, something like 3º, max 4º cooler, so it's not that bad. Maybe those are the V11 limits, who knows?

10° sounds a little optimistic, I changed from AS3 to AS5 and have noticed little change in my temps..

The Arctic Silver website talks about a "curing time", where it takes around 200 hours (I think?) for the stuff to cure, in which time the temps should continue to drop. So I'd suggest maybe taking it off, applying it again, and then letting the computer run itself in and see how you go.

Yay!!!

Today I was feeling lucky, so I took note of the temps and reaplied. Once I turn it on, I can see inmediatly that the temps are lower! 1ºC in both load and idle; but this time the stuff is fresh, while before it had had 24h to cure. So well... this is better. Gotta wait till next week to really see the diference.
So thanks to all of you

The more examples posted, the more I believe HSF compound performance lies mostly in the quality of the mount.

I'm impressed that you got ONE degree C of difference.

And I agree with Hammer. Although I wouldn't recommend the ultra-cheap compounds, there's not a lot of benefit to be had by spending a lot, either.

To second (or third?) hammer's and wumpus' comments:

Application often makes a bigger impact than the quality of the compound. El-cheapo white grease applied perfectly will outperform AS5 applied badly.

Even with my not-quite-perfectly-but-pretty-good applications, 1-2° difference between even nearly identical applications is pretty typical.

Well, I was pretty shocked too. Always since I saw a Shin-Etsu guide in amdforums, where it recommended to mask the base of the hs with tape and put it there, rather than the core I've used that, and always have had excellent results.
This time I tried to follow as5 instructions... not so good.

Follow my directions.

I second that notion!

i didnt too had big difference in temp in beginning, but in the long term my as3 was bleeding so i was getting higher temp

But as5 is suposed to be thickier, to avoid that

ps: Edward, I did follow your instructions, that was my second attemp. To be fair, with more practice it should be the same, but I find this method easier and faster for me

Indeed; such as it is with true art...

What do you mean your AS3 was bleeding? How could you tell?

Blito · Post by **Blito** » Mon Jul 19, 2004 9:01 am

You know what? as5 may have shaved only 5ºC at most, but it allowed me to lower my Vcore from 1,725 to 1,675. That didn't make a big diffence in temps either, but it's still nice

.
Besides, I've just aplied it to my 9600p

.
Thanks for the guide Edward, but what happened to the rest of your site?

smifou · Post by **smifou** » Mon Jul 19, 2004 9:03 am

i guess i could tell that temp went up after like 2-3 months and i think their seemed to be less of paste? problem never camed back with as5

Wait, are you seeing something wrong with the site that I don't know about? Seems to be coming up okay for me, besides the Gamma page needing updating really badly, as well as the Alpha Three page needing a bit of minor updating; shouldn't be anything noticeably screwed up though.

Please let me know if there are broken links or something.

Doh! It works for me from the link from your sig, but when I tried from the link in the tim page it didn't

Edward Ng · Post by **Edward Ng** » Mon Jul 19, 2004 12:29 pm

Thanx; I'll check it out.

EDIT: Okay, I see the problem (damn that's stupid); will be fixed by 4:35PM, EST.
