thermal paste Which Thermal Paste to buy and apply (Traditional and Liquid Metal)

[ryan]

I don't want to argue this as its highly subjective, but carbon specifically diamonds are tops when it comes to thermal conductivity..fact. but as for implemtation thats another story, and I don't think any paste has dropped me close to 15c vs arctic silver 5 since iv'e been laptop gaming(circa 2004)

Yes but you're not using a solid continuous piece of diamond. Its more like diamond powder suspended in silicone oil so the conductivity won't even come close to matching diamond.

 

Theory is one thing, how it works in real life is another matter entirely. Thats why actual testing is important.

I have to agree, in the spec sheet the polyester surfactant and polymeric dispersant are Trade Secret* and the other two ingredients are

                           % by Wt
CAS Number:    90 - 95
7440-44-0
Activated carbon

 

and

                           % by Wt
 CAS Number:    0.1 - 0.5 Trade Secret *
1333-86-4
Acetylene carbon black (100% compressed)

 

Its a good generic thermal conductive paste but not great.
Lifetime wise, sure it is a good thermal paste that age well because its carbon based. I can't speak for the bulk material because the solution is a trade secret.

There are no diamonds by its definition how you would imagine sharp tiny stones in a grey paste thats gonna scratch your silicon, its a very low concentration of Acetylene carbon black which is highly conductive but again a very small quantity.

Even Noctua's NT-H2 beats IC Diamond.

yeah im an ol OG nbr member... and as I understand it back in the day IC diamond was the best and still is..however trolls are saying it scratches the die and the performance is mediocre? weirdos.....the diamonds are nano particles and don't scratch the die

 

I used it on an old asus gaming laptop with overvolting I was seeing gpu temps exceed 100c with ic diamond they peaked around 80c...

 

argue this?

 

I applied it many times on many laptops and it never scratched my die? it kinda angers me with all the false info out there

 

on a tangent, the new switch state pads seem like they are tops. they are solid below 50c and liquid after

I can confirm it does scratch the die. But the scratching happens after many applications. I used to remove and reapply the thermal paste over ten times in a year due to various upgrades and yes, after so many re-applications the writting on the GPU die was almost gone. However, if you apply IC Diamon once every 2-3 years, I don't see a problem with it.

Sorry that my previous tone was a little harsh on the matter. By way of apologies, here's another little URL trick that I never see people use. If you want to direct people to a particular section of a webpage, you can craft a link that will jump to and highlight that section by using the following construction:

 

URL/#:~:text=Start%20of%20line,end%20of%20line

Apologies, I didn't realise that this feature has only been rolled out so far in Chromium based browsers. So it will work in e.g. Vivaldi or Opera, but not in Firefox which might explain why it's not working for you. See here for more:

i guess ima old fart....was under the old impression IC diamond was the best non metal thermal paste.

 

I had H2 and it was terrible..so what should I go for if im not willing to risk liquid metal? details

Thank you. This is good stuff and probably could use its own sub....url http ftp  tips n tricks  ?!?

 

 

I decided to buy this PTM7950 from Aliexpress...will let you know how it goes.

Doubtful it is real, its specified at being sold at 1kg or 300cc, its either a refill or fake.

Original product safety spec sheet says it is composed of;

aluminium                                                           cas 7429-90-5
zink oxide                                                           cas 1314-13-2
naphtha (petrolieum), hydrotreaded heavy    cas 6472-48-9 also called ISOPARAFFIN L
 

These are most commonly used as a screen printing product, being pre-applied to heatsinks.
Its closest competitor is probably Dow Corning 5000 series which is also used for screen printing on oem heatsinks but being slightly under Honeywell in terms of thermal conductivity.

IBM and now Lenovo had their heatsinks printed just like in the document below in a rectangle with small dots of thermal paste.

 

I found something else while checking out my go to distributors.

Either way, keep us posted ✌️

Thank you for that I will keep it handy.

Yes I suspect you are correct and it is fake, but I will give it a shot. Never know your luck in the big city.

Any updates? because i been thinking about trying this paste as i heard good things about it and its very effective especially with gaming laptops. Lenovo Legion laptops uses this paste as their stock paste i think but its in sheet form.

 

The SYY-157 i been using doesnt last long. Even after repasting my laptop with it again after 7 months im already experiencing temp spikes up to 105C when playing GTA V after a few weeks, Not sure if im doing something wrong or its a thing with AMD CPUs.

does anyone knows what is mx4 W/mK .? am using mx4. i think its fake even though the qr code says its geniune.

what would you susggest that is better than mx4.

It says  temperature range: -60°C ... +150°C, Thats not High enough

[aldarxt]

I've been using Gelid Extreme for years but have also used Star 700 and Halnziye HY510.

The Gelid is ok as long as you repaste within 2 years or it gets cakey and temps start to go up.

The star 700 claims to have silver in it and is kinda thin but not liquid and stays fresh but havent ran it for 2 years, maybe 6 mos. It also shows spikey temp readings on speccy, I assume its cooling off more quickly and noticed an 8c temp difference lower from the 2 yr old gelid.  The HY510 is thicker than Gelid and I thought it was almost as good as the Gelid but not as good as the Star 700. I like the constincy of Gelid and need to do long term Star 700 test. I am satisfied with Gelid Extreme as long as I keep up with it. I also need to buy more Star 700 because they came in tiny little tubes where the Gelid is in a 1 oz  jar and will last me years. So all this writing and I have no conclusions.lol

[KING19]

I ordered the paste version on Wednesday and im not sure i made the right choice as people on reddit said that the sheet works better and the paste version will take about 2 weeks to cure but i rather find out for myself and hope for the best

[Rofa1234]

There are indeed several of really encouraging tests for the Honeywell PTM7950, interesting paste. There is also a newer PTM7958 used by Lenovo: https://www.reddit.com/r/LenovoLegion/comments/tfxomi/lenovos_stock_paste_is_actually_ptm7958_a_custom/

I looked into this spec sheet: https://thermalmanagement.honeywell.com/content/dam/thermalmanagement/en/documents/document-lists/marketing/ThermalInterfaceMaterials-Electronics-Brochure.pdf

 

PTM7000 series has a thickness range of 0.2-1.00mm which is really good for bare die CPUs and should work on my uneven i7-1165G7. There is also a TG series of thermal paste, TG5500 has a viscosity rating of 300,000 cps. Lower thermal impedance rating than the PTM series but also a lower thermal conductivity. Maybe the thickness range is lower.

Lads and gents do you know some other paste like K5 pro as pad replacement?

Use the phrase "Thermal putty" in search. I think digi key offer several viable variants. Look also for Dow Corning and Laird thermal compound products. Well known brands for this type products.
