Ceramique Better than AS5?

I just swapped from Ceramique to AS5. I burned it in the same way as before, and i seem to have risen a few degrees, rather than drop the few degrees i was suppose to.

Any ideas?
 
You must have applied it wrong, as AS5 is MILES ahead of ceramique. Just put a small drop on the center of the heatspreader and that is all. No big globs.
 
it was done right. Small grain of rice sized pellet right in the center, use heatsink pressure to spread it into a nice round circle across the center, etc, etc.. Thats what was done.

I do this stuff for a living. I just never switched to AS5 until now.

Its not that my temps are bad by any means, its just that they are a few degrees worse than before. I didnt know if this stuff needed alot more time to burn in than the ceramique or what. My ceramique was giving me 3c better than this on idle after the exact same amount of time. As far as i know, they both had the same burn in time for full conductivity. And i must say, as of right now, ceramique is kicking AS5's AS5, if you catch my drift 🙂
 
Arctic Silver claims AS5 needs 50-200 hours to fully break in. Run your system 24/7 for a while and see what happens to your temps.
 
Yes, but it claims the same thing for ceramique, and again, the ceramique was cooler.

Perhaps the Athlon 64's like the ceramique better. Or the winchester core likes it. Not sure what it is. Its more curiousity than anything.

My idle with the ceramique after 3 "quickie" burn ins and cool downs, and then an "all night" burn in and then cool down was 32c. Now with the EXACT same test, the AS5 ends up idling at 35c.

I can not stress it enough, they were both tested the exact same way.

I have always found this to be the best way to get good temps:

SuperPI 32m run..then shut down for 5 minutes
SuperPI 2m Run and shut down again.
SuperPI 2m Run and shut down for 10-20 minutes.

Then Sandra aryth. Burn in overnight, then shut down for an hour.

This is what i did. I know its not the 200 hours yet, but my point is, with the ceramique, this same approach yeilded 3c lower temps.

And again, my temps are not bad, i just want to figure out what the difference is. Everything was done "To the T" by AS instructions, as always.
 
My experience is that when properly applied all premium T.I.Ms are within a coupld degress C of each other. Subsequently I base my purchase on how easy they are to work with, wether it is messy and hard to clean up or can I just wipe it off with a lint free cloth, does it have a good price per application or is it expensive like Shin-etsu? and does it dry up or pump after being subjected to the harsh conditions in use, and does it break down if stored for a good while. Ceramique' is the best I have used with all those factors considered IMHO, and silver based T.I.M. is the worst.

I prefer Ceramique myself, IMO it's just as good as AS and much easier to clean up.

You told me a couple years ago I wouldn't see more than a degree or 2 differences between T.I.M.s and of course you were right :beer:

 
I have tried most everthing, to include synthetic gear-lube, and lithium grease. Some worked outstanding, and some.............didn't. All that lasted for more than a day os so (toothpaste was AWESOME, but dried up in two days flat), were similar in performance. Enough so that I use the easiest to clean off that I can get cheaply. The Ceramique cleans up faster, so gets my vote over toothpaste, lithium grease, Margarine, Lard, Machine oil or AS5.
 
How was margarine? I was thinking about trying vegetable shortning. I think that would work pretty well and wouldn't dry out that quick.
 
Well you should use even less than that rice sized amount. Also spread it around evenly with your finger instead of the HS as when the heatsink is shoved down some could be pushed off of the core and you could have an uneven contact as well.

AS5 is supposed to be better (though slightly) than ceramique.

The athlon 64 core is huge. It couldnt spread off the sides anyhow. Ive put it on and looked before afterwards, it looks just like the AS website shows. A near perfect circle taking up the center half of the CPU. It would take alot to have leak-over with the P4 and 64 chips.
 
I have had my computer running for 2 weeks and my temps never changed (except maybe up a bit ) with AS5...no drop as expected
 
Ahh see, I experianced the SAME THING when switching.

Although conversly my father has been using AS5 forever and when he switched to Ceramique he experianced our problem.

I can explain it to you--when you cook in the TIM, particles of the TIM seep into the grain of the heatsink and core, fastening themselves almost indefinately. The only way you can remove them is by professional cleaning or using xylene based products (with some 'elbow grease'). The alternative to this is lapping your heatsink.

Basically, you lose cooling because you're essentially using one TIM on top of another. I could get more technical with things like deterioration, etc but I'm lame and tired.

You should feel proud, though, that I signed up with Anandtech JUST to tell you this. XD

first post what what?
 
I got AS5 and keeps my 3.0E@ 3.6 with a 1.55v Vcore at 44C Idle and 58C Full Load and thats with Intel stock HSF! But then again my case does have 4+ fans running in it so the better airflow might affect the results a bit...
 
What psikoticsilver said makes perfect sense to me. thanks for the input bud.

So am i better off staying with the AS5 now, or going back to the ceramique it had before?

How well did you clean the CPU before switching? Regardless you have some Ceramique still in there (unless you cleaned it out and inspected it with a microscope), so it's not really a 'fair' comparison since the CPU has Ceramique in the pits and grooves already, even if you did a thorough clean job.

If you tried a brand new CPU (or REALLY cleaning the CPU off well) and applying AS5 it should be better than Ceramique (albeit marginally).
 
I'll keep using my Ceramique, as it's easy to clean and it's non-conductive. I didn't get nervous putting big blobs on the memory part of the NV5 Silencer as directed. I also have enough Ceramique to last me until I'm well into my 30s. 🙂
 
I use AS5 because that's what I have. As everyone else has stated, it only makes a couple degrees difference, if any, and I don't think a couple degrees C is going to hinder my overclocking or cause my CPU to die.

Using your finger isn't a very good idea. Dead skin cells fall off and hamper heat transfer (or so says Arctic Silver).
