Hello Guys,
I am curious which of the two ( Thermal Grizzly - Kryonaut or Hydronaut ) gives you better temps consider using on a CPU Waterblock
What I read is that hydronaut as the name says is made for Watercooling but Kryonaut is made for "extrem OC" so what you actually should pick ?

Kryonaut is better than Hydronaut, the latter is just cheaper and has no silicone in it so can be used in those few applications were silicone based materials will cause problems.

Some TIMs have different optimal operating temperature ranges, but without subambient or unusually high temp conditions, that difference is marginal enough to be ignored.

Hydronaut is better simply because it is so much easier to spread then the Kryonaut, and I noticed no temp difference between the two on either my cpu or gpu

But it is not a 10€ different?
The hydronaut is the (new?) paste you get when buying a cpu block from EKwb. I am using the kyronaut right now but the difference shouldn't be that Hugh or?

I saw no difference in temps between the two pastes, I got the more expensive Kryonaut first, found it difficult to spread and you don't get much, ordered the Hydronaut next after looking the specs, I noticed the Kryonaut is 12.5 W/mk, and the Hydronaut is 11.8 W/mk, not much difference between the two and the temps have been pretty much identical from what I have seen.

If you don't mind a paste that spreads like clay then it wont bother you, otherwise the Hydronaut is much easier to spread and it's the only reason I would choose it over the Kryonaut.

Does anyone know how Hydronaut compares to Conductonaut? Can't find Conductonaut in NZ but have Hydronaut...

Conductonaut will outperform Hydronaut, by a lot....It's a regular TIM (Hydronaut) versus a liquid metal (Conductonaut)....

What are you intending to use it for? Between the IHS and cooler, Hydronaut would be better. Between the die and IHS, Conducntonaut would be better. On the GPU, Hydronaut will be safer....

Just looking at applying it straight to the GPU on my 1080 Ti FTW3... I applied Noctua NT-H1 today but finding no real difference in temps vs the stock TIM.

This guy was able to get around a 7C drop on an FTW3 with Conductonaut, I just can't find any in NZ... What do you suggest? I've heard Gelid Extreme is also pretty good...

Edit: Sorry 1080 Ti FTW3 vid here:

Edit: Really only keen to do it again if I can get good gains like with the liquid metal...

Just to add to this normal usage you won't see some stuff you see in extreme cooling. L2n and even some phase change people don't use several tims as they have several properties that make them inferior for their uses.

Hi,
Old thread but heck even Noctua NT-H1 will perform the same if not better seeing NT-H1 spreads better and not to mention is easier to find locally and is cheaper than any thermal grizzly product.

I've noticed something with the liquid metal stuff, they seem to get really cranky with unplated copper, escpecially when you are using it between an IHS and a cooler.

For the price and the arguable zero-performance difference... I've looked at a lot of reviews, and it seems CLU beats TGC more often than losing, and they are basically tying a lot. CLP is a more direct cross to TGC, as CLU has added graphite and bismuth, to make it more stable and easier to install. It takes a small hit to the max thermal transfer, but again in real world performance I've only seen a few cases where CLP edged out CLU. TGC is very expensive, and the amount TG gives you is much less than what CL gives you in a tube of CLU or CLP.

I chose to use CLU between the core and IHS on my i7-7700K. Using it between the IHS and the cooler, there isn't much point to be honest after staring at the temps. If you have an bare copper cold plate on your block, you should probably avoid it.

TGC: Thermal Grizzly Conductonaut
CLP: Coolaboratory Pro
CLU: Coolaboratory Ultra

The trick to spreading kryonaut is to spread it slow. It sticks better the slower you go. This also allows you to spend a thinner layer. The thinner the better.

I've tried all kind of things with Kryonaut and not spreading is the most reliable way to do it. Just put a vertical line on the CPU and make sure it's enough. Then tighten down the cooler and it will automatically spread. High end cooler have stiff enough springs to squeeze it as much as possible.
