is AS5 still the best?

Parkre, AS-5 is not conductive, it has capacitance. Explain please.

I still have some AS-3 here. I just put a dot of 3 & 5 on the bench, then checked both
with a VG OHM meter, no conductivity at all.

I have read that Ceramique has no capacitance. Ceramique epoxy is used to bond on
board sinks because it will not cause the FET legs to short.


OP, this has been beat to death. There are about 5~8 decent pastes within 2C of eachother.

In my opinion AS5 was never the best. Myself & others get slightly better temps from Shin Etsu X23-7783D.

other advantages include .... Shin Etsu is AMD approved, is not capacitive like AS5, and is easier to clean up.

^^^ - Agreed .... the inherent differences in people's systems and application techniques creates a margin of error
much greater than the slight performance (temp) differences between the respective pastes.

Which is why I listed possible advantages besides temperatures.
 
okay now that others have posted I will step into this.

AS5 is highly overrated to the point people actually believe it was at one time the best.

As others have pointed out in this thread--

On these forums both sides of this issue have been discussed over and over...
The simple facts are that the thermal paste that is shipped with most top end heatsink....Zalman...Scythe...Thermaltake...Thermalright..etc are all real good thermal paste. There is no need to go out and buy a tube of AS5.

Alot of people have done test using AS5 and other pastes and the end results have been no negligible difference in temps.

What with all the different ways people apply thermal paste and what with the different airflow schemes people use as was stated...

Have a good day!!
 
OK twitch, so it holds a charge but does not pass it. What does that mean?

My ohm meter showed no current flow. Does it need high voltage??

No, I didn't mean AS5 was conductive. The link I provided was to the liquid metal that came about a few months claiming to be better, but conductive....


I used Ceramique myself for everything because I bought a huge tube of it back in the day.
 
Also, if you read that link to the liquid metal, it says pastes could become conductive overtime..


1) Coollaboratory Liquid Pro was designed for use with high quality coolers made of copper or silver. Aluminum coolers are unsuitable for use with Liquid Pro.

DO NOT USE ALUMINUM COOLERS! Do not allow Liquid Pro to come in contact with any aluminum surfaces. Aluminum is not resistant against Liquid Pro and will result in damages to any aluminum surface.

2) Like all metals, Liquid Pro may act as an electrical conductor. This creates no problem if applied according to the directions provided, as your cooler is a conductive metal as well. Make sure Liquid Pro Does not touch any electric components. This could lead to short circuit when power is on. If you spill some of the Liquid Pro, wipe it away thoroughly before turning your PC on. Larger quantities can be sucked away with the syringe, or use a paper towel for smaller amounts.

Note: Even non-electricity conducting heat conducting pastes may acquire electric conductibility after some time. The reason is possible contamination with dust and metal particles by the cooling fan.

Please read all instructions included with Liquid Pro before applying.

oh, and paste that you use doesn't matter nearly as much how well you apply it. (i.e. putting thick layer of AS5 will be crap compared to pink pad.) The thinner, the better.
 
MX-1 from Arctic Cooling is the best. I know because when my Freezer 64 pro was mounted the first time with this paste (pre applied) the CPU load temp was 45C, later I took it off and reapplied with AS5 and got 5C higher. Room temp was the same. MX1 > AS5 [pwned]

While I would agree with you, mx-1 is better than as5. However, 5C seems like quite a big difference. Too big for it to just be the paste. If I had to guess you applied too little or too much and/or did not apply it the most effective way. So most likely a little user error in some way to have 5C higher. You are right though, mx-1 is better than as5. 🙂
 
I actually think AS5 and MX-1 vary in performance depending on the surface. MX-1 is much thicker paste and can't be spread out like AS5. I think it works better on heatsinks that have the very slight "grooves" like the Freezer64. Artic Cooling actually states the Freezer64 is designed specifically for use with MX-1, and it actually makes sense.

AS5 is much thinner and spreads out easily. As such, I'd think it would beat the MX-1 when used on heatsinks with a well-lapped, mirror finish.

DISCLAIMER: The above opinions have not been tested. MX-1 works great with my Freezer64, but I'm out of AS5 to test.

looking at the AMD website, they recommend only using thermal pads
and not paste or grease, unless you're needing to remove the heatsink often.

a good thermal pad should be good for the life of your rig. The problem with thermal pads is that if you remove your cpu cooler, you really don't want to reuse the same pad, and it's going to be a real pain to clean what's left of it off your cpu and cooler, and replace it, before remounting the cooler. Standard thermal paste has some of the same "cleaning" issues as with pads. Using something like Arctic Silver thermal grease is much easier to deal with if your in the habit of occassionally removing and then replacing your cooler, because it's a whole lot easier to clean up and reapply, because it doesn't get as hard and crusty like pads and paste tend to do. As for lifetime, whichever you use, properly applied and properly mounted, it will probably last longer than you'd keep that rig anyway, before upgrading to something else. I've seen old oem pc's which were over 5 or more years old and still working just fine with the original cooler/pad originally installed. I've never kept a rig of my own anywhere near 5 years.




 
I saw the title, "is ass still the best" and I though... "whatever floats your boat dude, more kitty for the rest of us." Then I was like, "DOH, he meant Arctic Silver 5, not butt pirating..."
 
LoL! Well, that puts a whole new 'twist' on things, Zap!

Astroglide, definitely! Doesn't get 'hard and crusty', like JEDIYoda said... 😉
 
AS5 is the best in my book!

Oh, you meant Arctic Silver 5... Nevermind - just these old eyes playing tricks again. 😉

..bh.

PS: I meant the generic AS5, not Zap's meaning (his mind not mine dropped that one)... .bh.

PPS: re. Thermal goop. There are many within a degree or so of each other now so I tend to prefer ease of application over an extra degree. Shin Etsu has come out with some new goops that apply better than their old crumbly clay stuff. One can hardly go wrong these days. .bh.
