How much better is arctic silver 5 than 3? Also is this the best thermal paste out right now, if not what is?

[schismspeak]

Maybe upto 2°C better in temps, and yes to my knowledge it is the best.

[Twigs]

i just dropped 2C off my idle temps from putting some as5 in place of my old as3...and yes, it is the best consumer level product(i have no idea about server/business thermal paste, it could be better but its probably only sold in bulk), some may argue, but then again, some may argue that beer counts as a vegetable

edit: wording

[archilochus]

Heres a link were you can see some differences in TIMs.
AS 5 was not avalible at the time of testing.THE FANMAN

The best grease is Shin Etsu X23-7804E3. Kicks Ceramique's ass and is NON-CONDUCTIVE! What more could you ask for?

[Jognt]

the shin etsu stuff is like very hard to apply, its very thick...

AS5 is also non conductive :P it is the other thing though... (the one allowing for cross-talk) it does NOT conduct high currents..

still, you should always pay attention when applying it anyway

(AS5 cools best, nothing is better...)

It's funny. I don't pay attention to modding and this forum for two months. I come back to find out there's an Artic Silver 5????

Nope it's not thick dude, the G-751 is THICK but the new X23-7804E3 is not... consistency the same as AS.

[dalilman52]

i prefer to use as5 on my cpu and ceramique for highly sensitive areas like chipsets...

[stamasd]

Frankly for having used silicone-based stuff before and AS5 now, I must say I don't see much of a difference. Maybe 1 degree at most.

[Mr_H]

What was it that I read on Tom's Hardware.... Oh yea

A paste is a paste is a paste.

[AntmanMike]

AS, AS2, AS3, and AS5 are all capacitive, meaning they allow crosstalk but not current.

[dalilman52]

stamasd, the reason u are prolly not getting better temps is prolly cuz u didnt remove ALL of the previous TIM's minute particles left in the hs..u should lap and use acetone to remove any traces of the previous one..maybe u didnt, becuase i saw a big improvement over generic silicon junk and using AS5/ceramique

[Shin Akuma]

Haha you're kidding right? There's no difference in temps between your so-called "silicon junk" and Ceramique...

BTW it's "silicone" not silicon...

Test them in a controlled environment and you'll see.

[dalilman52]

shin akuma, its called a "typo" maybe uve heard of it

[omaticrail]

I'm about on board with Stamasd. When my old "junk" silicone began to fail after 1.5 years, resulting in a slow (6-month) rise of 4 degrees (C), I thought I'd get some AS5 and smack those temps back down.....oops. After a hundred hours of running with a high speed fan and several load-temp to shutdown cycles, temps are still 1 degree (C) higher than just before putting on the AS5, for a total of 5 degrees higher than I had on day one, two years ago, with the silicone "junk."

Actually I have to confess that I don't know that it is/was silicone. It's whatever was supplied by Swiftech in those days.

I used acetone to take the TIM off the CPU, and a combination of acetone and 1500 grit lapping to clean up the block. *shrug* I can't imagine doing any better than that, but am open to suggestions.

HERE IS A HEAD TO HEAD COMPARISON BETWEEN 3 AND 5., 5 WINS ALL!!!!!!!!!!! LINK

[omaticrail]

I think the point being made by some folks (at least by me), is that 5 may be better than 3, but it would seem there are other brands that are better than either. I realize that statement may make me a fool for not just bowing down to the masses that "believe," but I do not believe so easily, when my experience is the opposite. I'm happy to be wrong, cuz I already paid for this stuff, but I'm waiting for the proof. So far, I'm running hot on AS5.

Omaticrail> Have U tried cleaning between the fins on the sink. The dust collected there during 1-2 years will reduce the sink-performance..

Sorry, but I put the AS5 on a brand new CPU (my 2nd Barton), and compare with the first one. And what I used on the other one wasn't even "thermal" paste, it was some generic silicone high viscosity grease used in vacuum pumps to provide seal under high vacuum.
