[EOL] Arctic MX-5 is here!!Tests incoming! Completed. Now its MX-6 testing time!

[Falkentyne]

Oh I'll pass on that.

That's specifically for TFX.
(I got the best results on my 3090 FE (most stable core temp deltas) applying it like that.
SYY-157 still needs full coverage but is easier to get on.

Anyone here use SYY-157 yet?

At 75°C it evaporates much faster than at 25°C; the problem is the Boltzmann distribution of velocities, some have what is takes to 'boil' off; so actually it both boils and freezes, some evaporates off, the rest cools down.

Taking into account evaporation and pump out is overthinking? These are real things.

A capacitor rated at 105°C will perform just fine at 105°C? Have you seen their rated life at that temperature? months, not years.

Straw man argument.

Evaporation is a trait specific to water (does oil evaporate??) and it's own specific chemical stability. Even ice evaporates (sublimation). That has nothing to do with thermal paste.

Anyway, I'm done with this conversation and trying to keep up with your endless meanderings. Cheers.

Technically, not true.
Evaporation is simply the separation of individual molecules from a material. Many objects and liquids will perform like this. It isn't intrinsic to H2O.
99% isopropyl Alcohol evaporates at room temperature even faster than water does. Apply a thin layer of 99% iso to a CPU IHS or GPU to clean it off and it evaporates in seconds.

Then we get into "Erosion" which is getting extremely off topic. We don't need go deep on a tangent about about chemistry and physical science.

And technically, "boiling" point is a form of evaporation, where the entire material transitions from a liquid to a gas.
Probably most important to overclockers is Liquid Nitrogen, which boils at room temperature and evaporates all over the place, probably the best well known example besides water itself, and dry ice (which isn't water).

Anyway I don't think evaporation is what anyone should be talking about here. What we're focused on is the actual separation of materials from an alloy or mixture into their individual components (e.g. the "Soupy" MX-4, etc), which one can call "Dryout" of paste, as opposed to "Pump out", where the paste is intact but gets slowly pushed off an even layer from the die, leaving hot spots (expansion/contraction+uneven/imbalanced heatsinks/bad mounting pressure).

False. All elements can evaporate as all elements have a liquid state depending on temperature.

(does oil evaporate??)

It does, the only question is how fast and at what temp range.

Anyway, I'm done with this conversation and trying to keep up with your endless meanderings. Cheers.

Oh come on now, let's be friendly. Andy's not trying to irritate you..

Hi,
Thermal paste one subject that gets heated by more than 1 or 2c too lol

 

[Space Lynx]

my parents PC's need re-pasted, they are ancient APU based systems the first Ryzen offered I believe. going to use mx-5 for them as well. its been about 5-7 years since i re-pasted did a full cleaning on theirs... so that will be fun... haha... I think my mom is running my 2500k cpu and 5570 gpu..., I can't remember. my dad has the APU

Then why does a bucket of motor oil sit in a shed and it's still there after 30 years, hmm? It's in a liquid state, so where's the evaporation?

I'm not mad, it's just tired of talking to people who have an imaginary degree in chemical engineering and make baseless claims with no connection to reality. Blanket statements are overly simplistic and the behavior of products should be considered on a case-by-case basis.

In general, typical room temps are not hot enough to do so. Heat it up to 200C and you'll see some action.

I'm not mad, it's just tired of talking to people who have an imaginary degree in chemical engineering and make baseless claims with no connection to reality.

As someone who holds several degrees, I would be willing to give him the benefit of the doubt due to a number of contributions Andy has made to numerous conversations. Additionally, there is also a language barrier to consider. His primary language is not English. He does his best to converse in English(very well IMHO) but sometimes things get lost in the translation.

EDIT: After a PM conversation it would seem I got him confused with another user. It would seem English is his primary language. Still, everyone thinks and communicates in a different way and this can sometime still get lost in the process.

We're all friends here, lets be chill.

That's cool, I have a few degrees in engineering myself. Mechanical and agricultural mainly, but I never mention them because they tend to have little to do with discussions about computing.

I don't know, a Mechanical Engineer would have done courses in thermodynamics and so be well prepared for thermal conduction.

I studied thermodynamics and did my dissertation on heat storage in latent heat materials. Pretty well prepared for it.

@95Viper Amen. I've had enough of talking about things that have nothing to do with thermal paste, it's a total waste of everyone's time.

 

[95Viper]

OK, stay on topic.
Do not do the "I have the bigger ego/degrees/intelligence or whatever you have".
As, said before... discuss the topic and not each other.

Thank You and Have a Nice Day.

For how long have they been using metal as opposed to metal oxide in thermal grease?

Are there any military specs for thermal grease?

Fun fact, Grease is a lubricant, intended for the reduction of friction on moving parts.
But I guess you already knew that.

Lots of people refer to it as grease; I can refer to paste or compound if you wish.

It's possible SYY, FuzeIce Plus and Halnziye HY-P13 are all related, in the same way that TFX and ZF-EX are.
Even the packaging of HY-P13 and SYY is the same.

the words "make your cooling life" on the Halnziye website are the same words on the back of the packaging of SYY. Might be the same factories involved.

Shifting across to metals, I wonder about galvanic corrosion
Brake Grease vs Anti Seize – Which Is Best For Your Brakes? – Grease Expert
talks about the possibility of Galvanic corrosion from anti-seize copper grease.

This might explain the use of Zinc and Aluminum but not Copper in thermal paste.

Ok folks, testing is done.

Let's state the particulars.

The system being used is a Dell Precision T3500 with an Intel Xeon W3680 using the stock cooler and a steady state 3700RPM 92mm fan. The testing software was Prime95. Temp monitoring software is HWInfo. The thermal interface materials being tested are as follows:
Dragon Star DRG102, compound very similar to Arctic Silver 5
Automotive Copper thread grease
Noctua NT-H1
Arctic Cooling MX-5

The tests were conducted as follows:
3 runs of 2 stages of Prime95 calculations which run for a little over 11 minutes per each TIM.

Here is how each was applied. I did not take photos of the Noctua NT-H1 as I forgot to. It didn't look any different than the DRG102.

DRG102


Copper Grease


MX-5


As you can see, I spread the TIM out in very thin layers. The DRG102 and Copper Grease were the easiest to spread evenly. NT-H1 was a little more difficult but only a bit. MX-5 was a bit of challenge but with a few minutes of work it spread out fine. It is as "sticky" as everyone claims of course, however this is a minor thing.

Here are the test results.

Dragon Star DRG102

This performance ranks third best in the tests.

Automotive Cooper thread grease

This performance ranks fourth in the tests.

Noctua NT-H1

This performance was second best in the tests.

Arctic Cooling MX-5

This performance was the best of the tests.

My conclusion is that MX-5 is a very impressive TIM. It bested NT-H1 by several degrees C in both idle and full load tests. It also bested the DRG102 handily. The copper grease proved inferior to the rest, even though the temps were within reason as expected given that the compound was used in this same system for nearly a year and performed well. NT-H1 is widely regarded as a premium TIM and has shown itself to be an excellent performer. For MX-5 to perform better than such shows it to be, at the very least, competitive with premium TIM's and at most superior to many of the of the top shelf brand TIMs.

The screenshots are here for you all to draw your own conclusions though.

IMPORTANT EDIT;
For the record, this testing was done as much for fun as it was out of scientific, professional and personal curiosity. The testing methodologies used are based on known valid methods but are NOT all inclusive. I'm NOT going to test every TIM on the market, nor am I going to test on a multitude of platforms. These tests are focused on the topic of discussion here, Arctic Cooling MX-5. I deliberately chose to use a TIM that is a budget known good performer, a product not specifically designed for the purpose at hand(for giggles and to be an odd-ball) and a TIM that is considered to be a premium product for testing against MX-5.

That said, if you have a problem or complaint about the testing methods used or the fact that the products tested were limited, feel free to buy your own products to test, spend your own time conducting said testing and then post your own results. Whining about what I did or didn't do that somehow doesn't meet with your satisfaction will only earn you an unpleasant reaction, which will likely include open and public mocking.

Only warning.

 

[ThrashZone]

Hi,
Nice but you really need a new wallpaper lol

Tightened my water block on 9940x with mx-5 and core temp spread is now a lot better 38-42c on just a little 4.2 everyday clock I use not bad on 14 cores might crank it up this weekend see what happens at 4.9

Before temps were whack bad highest was 49c think I said earlier on this thread.
Funny how pressure helps and I thought all four were pretty evenly tightened but I do not spread very often I use x method

 

[Shrek]

Any great advantage applying it to both surfaces?

I'd still argue that since most any good TIM gives good results, longevity is important and wish you had included the infamous 40% diaper cream as that gave good results for me (as good as GD900) and might drive a comparison on more than just temperature.

Just in case it comes up, I am NOT suggesting the real life use of 40% diaper cream, but I find it sobering that it performs so well. Anyone willing to test it (to verify my results)?

 

[80-watt Hamster]

Cryorig instructions recommend tinting the cold plate, so I'm inclined to say "probably".

 

[Secret Rival]

yeah I saw that when I ordered. for ten cents its worth it imo, just in case. lol also the little spatula might come in handy for other stuff so meh.

If you've seen the movie 'Stripes', then you know it's always wise to keep a spatula handy.

MX-5 is indeed impressive on a desktop CPU or a video card.
It's atrocious on laptops though. Too thin. Same problem as "new" KPx (old KPx was awesome on laptops).
