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

Good shizzle then!

Maybe we should search and find an industrial grade thermal paste.

National Renewable Energy Labs in 2008 did testing on a selection of thermal pastes, including TC-5022, a Shin-Etsu paste, - and the perennial AS5.

Very interesting report. Even if you don't care about any of these pastes it's worth bookmarking.

AFAIK Dow Corning is what's stock on Intel heatsinks or it was for many years. Stable paste, performs similarly throughout its lifetime. Also used in aviation.

What do the military use?

They have no idea. The contractors building whatever it is that has paste in it will use whatever compound allows them to meet spec at the lowest cost possible.

In general, using mil-spec as any kind of yardstick is a bad idea. If you want to know why, ask someone who's served. (Full disclosure, I've done the asking, not the serving.)

I have some mobo/CPU swap tests to do later next week. One box has an Arctic LF II 240 w/4 Silverstone FM121's in push/pull at full speed (110cfm each). It currently has an Asus ROG Maximus VIII Hero/7700K in it. The other has an Asus ROG Maximus Hero XI WiFi/9900K coooled by an Arctic LF II 360 w/6 EverFlow R121225BU's (OEM version of the FM121) in push/pull. I also have several 150cfm Delta FFB1212EH-PWM's to play with on hand as well. No side panels will be used on the cases during testing.

I have several different tubes of thermal pastes in my inventory. I happen to have two 4 gram tubes of SYY-157 that haven't been opened yet that I'm going to try out. The test board/CPU combo is a new ASRock Z690 Steel Legend WiFi and the CPU is a new Alder Lake i5-12600K. Since the two test cases have the radiators & fans mounted externally (something Arctic says they think should be done more often with hot running CPU's) swapping the mobo/CPU with a NVMe drive running a fresh install of Win 11 Enterprise is the easiest way to go. I'll be shooting for 5.2GHz on the P-cores and highly suspect the 360 with Delta fans at full speed will give the best results overall. HWINFO will be what I measure the temps with.

I have some MX-5, MX-4, Gelid GC Extreme and AS5 I want to compare against the SYY-157 after I find out which AIO/fan combo gives the lowest temps. Personally I've had the best results with the Gelid over the years. I want to see what combo performs best against my Cosmos II with a Z690 Steel Legend WiFi/12700K @5.2GHz cooled by a LF II 280 mounted externally with 4 Silver Stone 140mm FHP-141's at full speed (171cfm each) in push/pull using Gelid Extreme. It works great now but when I first built it 6 months ago using a LF II 240, MX-4 and the stock Arctic fans mounted internally I had some thermal throttling issues under load even with the side panels off.

What do the military use?

They adopt the "Don't ask don't tell" policy (they'd use products that dont need thermal paste in teh first place)

"TC-5022 is formulated with advanced silicone fluid that interacts with thermally conductive filler particles to form a highly stable matrix that helps to prevent pump-out and other common failure mechanisms."

I guess pump-out is real.

Pump out is absolutely real - we're just using products already designed to fix it (Tight contact with immobile flat surfaces, and we've had decades of thermal pastes used in PC's to improve the formulas)

I never had a doubt, but some here might.

 

[lexluthermiester]

However it is been speculated that noctuas are notorious for it's pump out effect.

Pump out effect has yet to be proven in all use case scenarios. However, they do dry out and lose some of their effective cooling ability.

NTH1 is total shit..

I wouldn't go that far as my own testing showed it was a good performer. It's not the worse, but it's not the best either and as mentioned above, it does dry out.

Greatly doubt. Highly subjective situation. I've been working in this industry for decades and have worked on tens of thousands of machines and have never seen definitive evidence of it. Not once.

Somewhere out there is a meme of Andy and runny pump out... hehehe.

What a great information. Thanks for sharing with us..
I think stock pastes aren't the best, as they are built for everyone, not just overclockers

What do the military use?

What does it matter?

Military devices undergo a far greater range of conditions than a consumer PC including traveling at high altitudes (above 50,000 ft. and below zero temperatures) as well as higher ambient temperatures and extremes of air pressure, humidity, radiation, etc.

Your typical consumer PC enjoys a cushy comfortable existence in the same general range of conditions that humans comfortably tolerate. My house's indoor temperature ranges from 60-80 °F (16-27 °C) throughout the year.

My gaming PCs don't need the same thermal compound as the missile guidance package of an ICBM or a military satellite's CPU. Heck, even the automotive electronics in my Toyota are subject to a far wider range of operating environmental conditions than my PCs.

In any case, what the military uses was probably formulated in 1989 and comes in 5-gallon buckets or 50-gallon drums.

My vote is MX-5.

Will you still prefer MX-5 over MX-4? (Without taking into consideration the price)

 

[lexluthermiester]

I've used both, MX-5 performs a little better, so yes. The comments about it be overly "sticky" are an exaggeration. Yes, it is a bit tacky, but nothing more than many other TIMs.

 

[mclaren85]

Has anyone used Halnziye paste? It looks like a generic brand but some claims it is performs very well.

How much? If it's cheap, try it. At the very least, it'll do the job...

 

[mclaren85]

It is about 5-6 $.
Btw, I've just bought Thermal Grizzly Aeronout from amazon.

Hi,
Last I looked mx-5 price was dropped on amazon to about 8.us so looks like arctic is dumping stock instead of recalling it since eol.

 

[lexluthermiester]

It's always been $8.99, price hasn't changed...

Quit with the disinformation.

Hi,
Saw it off the dudes link he posted to arctic website about eol and buy from amazon link there

It showed 33% off at that time down to under 8.us so arctic posting disinformation links to amazon is all so talk to them about the issue you accuse

https://www.amazon.com/gp/product/B08T6D1S73/ref=as_li_tl?ie=UTF8&tag=arctic.de-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B08T6D1S73&linkId=938c4513337ee3daa0678abd70f20832&th=1

Now third party has it for sell for 35.us

My link is from the Amazon Arctic store direct. Third party sellers are just scalping.
