Hello, anybody know the best thermal paste? The one that chills more

I'm using Arctic Cooling since many many years and pretty happy with their products

Gelid GC-Extreme is good.

Thermal Grizzly Conductonaut and Cool Laboratory Liquid Ultra....they are liquid metal

they corrode aluminum though..and they are CONDUCTIVE so apply carefully, their application is not the same as thermal paste.

I replace my thermal paste regularly every 2month, I live in the tropical area plus almost half of my rig was R9 series. I'm using DeepCool z9 it cost me around $8, I'll need ten pcs each time replacing the thermal paste. The results are pretty good for me.

I have AMD Vega 56, but i couldn't unscrew the screws :( All the crews now mess up since i forced to open with screw driver. Any solution for my case?

A word of warning.

If you got an old GPU like a Radeon 7950 or some other 5 year old GPU, then avoid doing any thermal paste changes.

Basically the factory paste is old and like glue and when you separate the heat sink from the chip, it will be hard to get off which will end up using force and you might break some of the solder balls which attach the GPU chip to the PCb board.

thermal paste will degrade and become inefficient, in my experience in the past..my 280x rig hangs, the problem was one of the the GPU needs thermal paste replacement it was Gelid GC Extreme, lasted for a year..when they dried up and become in efficient, they were like dry thin film of brittle grey stuff.  

haven't seen one like your're describing...i typically replace thermal paste for about a year or two...not five years (they don't last that long, performance wise) and these good thermal paste don't act like glue..

anyway always try to lift the heat spreader a bit on all side to loosen the "stickiness" and not on a single side only...

You can try with giving some oil to the screw part, let stand a moment. You could use a bigger size of screwdriver. I have the same problem before, and I fix it with an electric screwdriver, it will spin hard and force the screw to rotate.

What I found is that if the thermal paste is replaced, it usually only lasts a year or two.

If the factory one is left on, it lasts much longer.

The difference in temps were very little from an old 5 year paste to a new thermal paste.
Wasn't worth damaging the GPUs.

Of course not, just a bit or much reducing GPU temps also depends on new thermal paste that used. When I use DeepCool Z5, it can reduce GPU heat around 3-5 degree. DeepCool Z9 was giving me more significant heat reducing, above 5 degrees comparing to old few years paste that has on it.

Reducing 5-degree of heat on GPU is worthed on mining process. Use spray cleaner for an electrical part to clean old thermal paste seem like more safe.

My findings are exactly the opposite. Factory paste always seems to under-perform for me, very consistently. It seems that either I have the worst luck or the manufacturers use extremely low-quality paste. I always end up replacing my thermal paste after, at most, a year of usage. That's pushing it though if I want optimal temperatures.

I've noticed that low-quality or old thermal paste alone is enough to really drive up temperatures. These are just my experiences, but since they differ from yours I wanted to throw them out there.

I never seem to care much about the company of the thermal paste, so long as it meets regular specifications and gets replaced regularly everything should run smooth. Regular maintenance and replacement of thermal paste is needed, it is not a "set-it-and-forget-it" kind of thing.

It doesn't matter which paste you use. I've heard people using toothpaste ffs lol!
Just clean the paste and reapply regularly.
I stick to a local brand called Fluxon. I m pretty sure you won't find it where you stay though.

All this assuming you can disassemble the heatsink easily without causing any damage to any components.

Are you serious about the toothpaste? I'm asking for a, uhh, friend. I'm wondering if that would actually work or if it would cause internal damage of some kind.

The hardest part about reapplying the thermal paste always seems to be either reassembling/disassembling the heatsink or simply putting back on the case of the rig.

i've used toothpaste a few times  on cpu's when i ran out of thermal paste...now that i have a stock pile of thermal paste because i'm a miner, there is no need to use toothpaste..just saying it can be useful for emergency situations..

you guys should be looking at liquid metal..recently I delidded an i7 8700k, it reduced the temp to around 15c (prime 95 stress test)........my gpus with liquid metal are now exceeding my typical thermal paste replacement time compared to one of the best thermal paste out there that I used-gelid gc extreme.....it also has lower temps compared to typical thermal paste.

That is absolutely incredible. You learn something new everyday. Would it be better to leave relatively old thermal paste on or replace it temporarily with toothpaste? How extensive has your testing been with toothpaste, and do they share any similar components? Why does it work? I have a plethora of questions about this nonsense. Are we sure that it actually is doing the job of thermal paste and not that of a placebo?



Can you clarify, do you mean it reduced your temps by about 15c or to about 15c? Cause 15c is absurdly low temperature, I don't even have that at idle. My room is hotter than that.

I can't remember exactly but i think the toothpaste don't perform very long..like for a month or two you have to replace it...having that "paste" material in between, is somehow better for two surface (cpu and heatsink) than nothing, because if you don't put anything there the air gaps are worse than toothpaste..

..
15c is taken off like from 95c to 80c....remember liquid metal is CONDUCTIVE, brushing a thin layer is the best way of applying it, as far as i know..

what i'm trying to point out (benefit) in using good thermal paste specially liquid metal, aside from good temps...the replacement time, what if you just have to replace liquid metal every 3 years or more...also the effort and time lost, mining rig can stop/hang if just one card stops due to overheating core......sometimes even if the temps in your monitoring software is good, the card still hangs...happened in my 280x's a few times and thermal paste reapplication solved the issue.

I think we all read the same Toms hardware article about 10 years back.

I used tooth paste also on some KnCminer Jupiters which had very little or no thermal paste at all.

Basically since the ASIC chip was huge, it wasn't worth using Arctic silver so I just used tooth paste and it worked better than leaving nothing at all while I waited for a huge jar of thermal compound to come from China.

yup i read it somewhere I can't remember..came in handy...feels minty and clean on fingers hehe

If it is the air gaps that are the concern, then wouldn't something like Vaseline or petroleum jelly do equally as good a job as toothpaste? Anything that has that kind of texture and conductivity properties should do the trick, right?


That's what I was thinking, maintaining 15c sounded like some next level stuff. Still 15c cooler is a big deal when it comes to constantly running. That changes the lifespan of your hardware significantly, for the better.


I must be out of the loop then. I wouldn't mind a link if you manage to come across that post again.

ARCTIC SILVER 5

Besides liquid metal which is much more difficult to work with, there is NO better thermal compound that exists!

Here's (https://www.tomshardware.com/reviews/thermal-paste-comparison,5108-9.html) a TomsHardware article with a comparison of toothpaste against various types of thermal pastes using a CPU cooler with 'high' mounting pressure. Doesn't seem to perform too bad if you don't have anything better, but I have a tube of MX-2 in my house for CPU and GPU use; it's not much more expensive than the AS5, and it does a bit better in most applications. Unless you're buying paste from a noname brand or in bulk from China (I have had pretty bad experiences with bulk paste from Aliexpress), any thermal paste should work as long as you're applying it in the correct amount, cleaning off previous paste and mounting the GPU cooler on properly afterwards.

Arctic is  best for me.

In the case of your Aliexpress mishap would you say that you would have been better off with the toothpaste? Rather than the poor quality thermal paste. I'm sorry that I am so caught up on this, but I have never heard of such a thing and it's had my maximum interest ever since. Cause it sounds like, you'd be better off with some good toothpaste than you would be with some bad thermal paste.

in fact if we are not speaking about some crazy no name paste from unknown source, I think any branded thermal paste will do. it will be better then the old one, because it is fresh )) but seriosly, I don't think that 1-2 C will make a great difference.. so arctic silver is good choice, but if you can find something cheaper locally - source it

If you are looking for best thermal paste (https://www.thecrazybuyers.com/best-thermal-pastes) then I would recommend you to go for ARCTIC MX-4 Carbon-Based or Arctic Silver 5 Thermal Compound.

Thermal Grizzly conductonaut, and other Liquid metal products, is gallium based and it WILL alloy with your copper heatsink, reducing heat dissipation over time, and you will need to apply it again, and again, replace broken alloy heatsing, and add it again, and again, and so on.... i would only recomend it under ihs as it does not alloy so fast with nickel plated copper on the ihs, or in applications where replacing the heatsing in 1 to 2 years is cheap and not a problem.
