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

[Ruru]

Hi,
Just a couple weeks ago did my 1080ti and a week earlier did my titan xp after disassembly after finding sludge after a year of using mods water filter don't lie and time to look through the plexi gpu water block
lol
Went back with nt-h1 though but seems I disassemble yearly anyway so longevity past 12 months isn't needed also went back to distilled and biocide/ inhibitor+ products instead of premix.

Yuck, that looks nasty. Probably gives a "nice" increase in temps?

 

[lexluthermiester]

That's basically an epoxy.

Yeah, but that's plastics. There shouldn't be any bonding effect on metals...

Come to think of it. Its a gap filler but I gues the thermal conductivity would be horrendous.

You'll never know unless you try...

For science!

 

[toilet pepper]

I'll try it on metals first before doing something stupid. I have a spare ryzen 1600. I wont be doing it anytime soon though.

Is it possible that MX-5 works better with AIO's than it does air coolers? or let me re-phrase that, is it possible that MX-5 scores would equalize more on an AIO vs an air cooler?

so like I gained 2 celsius going from mx-4 to mx-5 on my tiny air cooler... which made me sad. should have kept the mx-4 after all...

but if i were to do mx-5 on an AIO, would it be equal to mx-4 on the same AIO? I can't test this... so if anyone else has tested it please let me know. it's not fiction that some pastes were better with laptops or air coolers like liquid metal, but i'm not willing to risk a leak and frying my mobo with it...

What air cooler did you use? I'm also wondering if you cleaned both contact surfaces thoroughly with IPA before reassembly with MX-5. It's possible to forget that the heatsink also needs cleaning....

i cleaned both with 91% isopropyl alcohol, very thoroughly as well.

Yeah, so there shouldn't be any issues there. The other thing to watch out for is the method of application, I personally apply extra globs of paste above the CCD and I/O die to make sure those heat-generating areas get good coverage.

Biocide will turn cloudy too. I just use a bit of blue antifreeze. ~ 15% or so with distilled water, that's the only thing that hasn't completely deteriorated after a year.

I've been wiping old paste away with TP since my Pentium II/GF2 days.

Won't that mess with the specific heat?

 

[Sithaer]

Can't add much value to the topic but I will just leave it here that I have GD900 'the original edition' on my RX 570 for ~5 months now with no issues.
Its holding about the same temps as whatever Gigabyte put on it in the factory, maybe 1-2 Celsius lower but its hard to tell here cause my room temps are all over the place all the time.

In general I'm using MX 4 for years now on my CPU, it gets the job done but then again I run everything at stock so its to be expected.

Checked now and MX 4 2019 edition and the new MX 5 is pretty much priced at the same in one of the biggest retail shop in my country at around ~7$ for a 4g tube.
In comparison the base Kryonaut 1g is slightly more expensive than that so I don't think I will ever switch from the MX line as it proved itself to me over the years. 'last time I let it on my CPU for 2 years and it wasn't dried out at all'

As for weird thermal paste ideas, well theres a known tech dude in my country who likes to try out really weird stuff.
He tried peach jam, chili sauce and basically anything in the household that was possible to apply on a CPU/GPU and compared them to the MX 4 baseline.

I think you have added value, namely the longevity of GD900

• GD900 seems to be based on Aluminum Oxide and Zinc Oxide and is good for -50°C to 200°C
• GD900-1 seems to be based on Aluminum Oxide and Silver and is good for -50°C to 120°C

120°C seems a bit low to me.

@lexluthermiester any comment on this? ^

Not really. Antifreeze is also a coolant be design. Should actually work better than water only.

Not sure to be honest. The difference shouldn't be too dramatic.

Specific heat of

• water: 4.2 kJ/kg K
• anti-freeze: 0.6 kJ/kg K

That is why it is not a good idea to run a car on pure anti-freeze.

So a 15% mixture has about 13% less heat carrying ability.

True, but when combined they work very well together.

Yeah I was kinda expecting a degradation but its stable so far.
Before re pasting the max I saw was 72-73 celsius in very demanding games and mainly Unreal engine 4 games that push my GPU that far even with an undervolt.

Whats constant is the undervolt and the fan speed, I've disabled the fan off function and set a fixed 40% fan speed instead. 'at that speed its basically dead silent'

So far I very rarely see my GPU 'core' reach 70 celsius with GD900 and its starting summer here, most of the times its around 65-66 nowadays.
With the dried out Gigabyte paste it was easily hitting 72-73 while playing Witcher 3 last summer.

I will keep monitoring it and see what happens during summer but its promising, especially for the price and the ammount we got for the money. 'My bro bought the GD900 after I told him about it after watching Brian's Techyes channel'

Hi,
Yeah too much biocide will cloud
Inhibitor+ is what controls the ph level I believe, sweet spot is to maintain ph7
Biocide will also not play well with nickel plating
I have used antifreeze mix think it was 15% but I used ac delco gold I named it golden shower lol

nothing in a PC is gunna run at 120C

It's a compromise, nothing unusual there. In chemistry basically everything is a compromise.

Just for fun: some semi-conductors run at 500C
Extreme-Temperature Electronics (Tutorial - Part 3) (extremetemperatureelectronics.com)

and they sometimes run diodes and transistors in power supplies purposefully hot (by reducing cooling) to increase efficiency.

TPU hates IC diamond with a passion, after their CEO came on here being an ass when it was damaging products and made weird comments about killing peoples grandmas, and threatening lawsuits.

Yeah, it was fun times.

That one went down in the great book of grudges, it did.

Nothing silicon anyways.

"Actually Si devices have been operated to about 500°C as mentioned earlier in Tutorial #1."

Again, this is just for fun... not trying to prove a point even if I would still prefer a thermal grease that could take higher temperatures so I know it will last decades.

"PC" was the context. I'm aware silicon can go much higher in non-PC configurations.
