Anyone tried this stuff before?

Is that nail painting or something?? :stick:

I wonder if it beats liquid metal?
I just applied some to my setup and I still haven't picked up my jaw off the floor! - my temps dropped 13c under load :slobber:

Sounds more like you had a duff CPU block mount prior to applying... no thermal paste can account for a drop that large.

Nah, I mounted the block plenty of times.
Originally I had:
31c idle and 48 under load with my silent watercooling setup.

Once I whiped and cleaned the AS3 off my block and core and replaced it with a thin film of liquid metal and my temps changed to:
28c idle and 35c under load

it has remained at 35c under load despite raising the voltages also. I moved it up to 1.48v until the meter showed an increase of 2c under load. Otherwise it sits hapilly at 35c

The stuff is simply amazing!

I'd have to agree with Marci, 13c can't be right! I would love to test it myself, but I haven't found anyone selling it yet...(the liquid metal thing that is)

Not a debatable point. Something else accounts for the difference. A thermal compound and it's application CANNOT account for 13 deg C load temp drop alone.

Well those are my results. - sceptism is a moot point since this is what I got out of it.

But you cannot conclusively account your findings to a variance in TIM and TIM alone. Therefore, your findings are not conclusive, empirical, proven or otherwise especially when it takes a paper of this calibre (http://www.electronics-cooling.com/html/2003_november_a2.html) just to outline the difficulties of measuring the performance of a TIM. Don't tell me you've suddenly cracked how to do it when (the world over) scientists and ThermoDynamics engineers can't manage it accurately or agreeably.

Zalman's OWN testing only shows a 2 deg C difference between "High Performance Compounds" (ie: Silver based compounds) and their new stuff... and a 5 deg C drop between "regular compounds" (ie: silicon based white goop) and their new stuff... your old compound applications / block mounts were flawed. Your current mount / application is not. Yes, Zalman's TIM exhibited a drop, but it is NOT the sole cause of a 13 deg C drop, and end-users would be foolish to expect such.

Yes and look at the graphs... I don't see a 13C drop, I see a 6C drop at _best_ in their tests.
I must concur with Marci, 13C drop unless you are talking temperatues of 80C is not plausible, for common computers a 13C drop would mean that you are now below room temperature first of all, almost even for my computer which is running really hot because I want it silent.

I'm guessing as marci, your previous setup was probably a little skew or perhaps some AS was in contact with the area around the core. 13C drop _is not_ possible for computers at sane temperatures, the paste only improves heat transfer, it does not dissipate heat itself.

Well I didn't think it was a such a big deal, but after reading the importance placed on my accomplishments your plight has driven me to publish a paper and claim a spot for the next annual NP. :toast:

The only thing I can attribute to my results is that the AS3 was not fully set, or it may not of been fully optimized in terms of amount and spread. However I should point out that this is a common occurence in many cases and that the use of liquid metal eliminates these problems.

So I would say that the liquid metal is responsible for the 13c drop on my setup when compared to the alternative brand.

But this review surely can't be right?? 8c better than ceramique? :stick:

None of the companies conducting these reviews have the equipment to conduct them and produce empirical results.

A TIM's performance cannot be measured on PC Hardware. Fullstop. All these reviews are pointless other than to create a buzz regarding a product. That is all. Everyone will draw their own conclusions after purchase regardless, but misleading comments and reviews will merely serve to bring about a lot of folks pissed at that product for not living up to it's claims. Solution - make no claims unless they are empirical. The same held true for Waterblock reviews, Radiator reviews, Pump reviews... if it's for use in a cooling system, then generally it's performance cannot be reviewed and summarised on a PC or using PC Hardware due to the inherant variances in that hardware. Ignore any reviews you read on Thermal Compounds unless the testing methodology is scientifically sound.

i think you are all forgetting the swiss and cheddar cheese TIM results.

Toothpaste beat everything didn't it?? Well reminded - a link to that article may be invaluable here... http://www.dansdata.com/goop.htm


Firing up my Minty Fresh Thermal Transfer Experiment produced, rather hilariously, an excellent score - 0.47°C/W.

That's right - Toothpaste Superior To Arctic Silver 3! Film At Eleven!

Over at OCForums SSS is testing it and trying to talk to Zalman.
