Always been about that no?
What's this like? Also what about conductonaut?.
Not really a deal imo

Forget about Conductonaut, only really useful in certain situations and the risk factor is too high

If you're wanting a premium paste then Thermalright's TFX is where it's at right now and available for ~£10.50 on Aliexpress (6.2g tube)

Really good stuff, don't own the 2019 one have the older one and it does the job really well considering the price
the 20g is always the best deal from time to time, sometime as low as £13

I use a lot of water-cooling and always find my paste has dried whenever I've had to take off a heatsink, very disappointing!. I think you guessed I buy decent enough stuff ( usually thermal grizzly or arctic silver), but performance over time is usually crap, hence I thought "what's doesn't evaporate or dry out?".
What's the tfx stuff like for performance over time, as I'm my current gaming rig needs a bit or a heatsink renewal.. it's been some time, and it's probably like dust by now!.

useless unless you are a system builder or it technician. never buy bulk if you don't need it. This paste has maximum life span of 5~6 years unopen or applied to cpu, open but unused goes bad after one year or so

How?? so, under heat should be replaced once per month then

I had i7 7700k overclocked to ~5.1Ghz and running on watercooling for years now and it was pretty normal for me to have to change thermal paste every 4~6 months. stuff with better thermal conduction usually dried much faster than cheap stuff. nocturno was my choice but overall it was very pricy to use

TFX was only released in February so I've no idea what it's like over time. Have a google of some reviews and decide for yourself if it's for you or not
Guru3D Thermal Paste Roundup 2019

guru3d.com/art…tml

Summary and conclusion

Choosing the right thermal paste is a very important step that most people completely overlook. However, believe it or not, the decision that you make does matter a lot when you are building a new computer. Since there are so many brands on the market, there is an obvious confusion that makes things difficult for the average user. And when that happens, people pick the cheapest thermal paste they can find.

Although buying thermal grease is a fairly simple and straightforward process, the really baffling moment comes when you end up facing a heap of different companies selling products that promise huge differences. In truth, the differences between these options are not really that big; and as long as you bought something made by reputable brands like Noctua, Cooler Master, Arctic, or Thermal Grizzly, you are good to go.

Hmmm... Longevity is important to me as I don't get around to reapplying much if ever.
If my thermal grizzly has stood up ok when I take off the heatsink next weekend, then I'll clean up and reapply.
This weekend I'm trying to join some raids on division 2.. Give the thermal paste a workout!.
Thermal grizzly kryonaut is still the best

Followed closely by gelid gc extreme

Well known fact
What is the best thermal paste for CPU's these days? I have always gone with Artic Silver 5. Can't say I have looked about in the last 10 years or so.

Replacing paste every 4 to 5 months would make it perfectly useful.
Scan give this as a freebie for any product you purchase from them. I'm assuming it's on par with the original version.
If you are using AS you probably won't see any difference in switching to one of the "pro" brands tbh unless you are running a silly overclocked rig with awful cooling!

Providing you have prepped it ok and applied the right amount with good contact I'd stick with AS personally

Not anymore. Thermalright TFX has higher thermal conductivity than kryonaut.

IceGrenade24/08/2019 15:38

It's liquid metal, its electrically conductive, if it gets onto your motherboard or other components you risk zapping it.
It also can't be used on aluminium surfaces.

Fair one, it normally gets changed at least one every 2 years with a "pea" size and I have Corsair AIO 120mm so should be fine, just wanted to keep temps as low as possible (only really going to 60c on load anyway).

I use Thermalright Chill Factor 3 for years, it works amazingly well. But hearing about this new TFX version I'm keen to try it, any good places to buy from?

Yao Yue Store on AliExpress is by far the cheapest of anywhere I've seen (100% legit seller)
I agree with the people here saying don't over think it. So long as you aren't doing anything particularly extreme like going for overclocking world records it really makes very little difference which you use from the reputable brands.

I do have to agree that Conductonaut is a bad idea for most people though. It is very liquid and very electrically conductive.


Another decent option these days is the Carbonaught pads. Close enough to the performance of most compounds as to not to matter in most cases, easier to apply, never dries out and is reusable.
Pretty good paste.

Here's a comparison of the best pastes that was posted recently on Guru3D:

how do you know its 100% legit seller ? and if the paste is that good how come its not in the UK and you have to inport it, I went with noctua NT-H2 but have not tried it yet
For me this worked great. My laptop was 80 degrees at idle and after applying this and cleaning fan it's 40 degrees at idle. Thermal grizzly is meant to be better but for the general user this will be fine there's thousands of reviews on Amazon.

Anyone doing this on a laptop be careful as I cracked the case in numerous places and broke one of the ribbon cable clamps (the thin one for the power button). Does anyone know if this can be fixed it's currently held down with masking tape.
2 types of thermal paste you can buy cheap and expensive, there is no middle ground!

The expensive stuff has various packaging and faff but is essentially the same. The cheap stuff is for a £1 or so, and sold on amazon for about a £5 but is exactly the same stuff. I brought Arctic MX-4 paste from a bay seller in the us and it is the same as the more expensive stuff. I paid £1.09

Yes, according to the review I linked above
yiu25/08/2019 10:51

Is this better than the Arctic Silver 5?


It's safer because it doesn't conduct electricity so you can't destroy your motherboard if you get some paste on it. But as5 supposedly performs better but is electrically conductive so a bit risky.
yiu25/08/2019 10:51

Yes it is much better, as it is safer to use. And also performs better then AS5.

I went with the Thermal grizzly conductonaut in the end.
