skawster Ok well I figured out the issue with the temps, I got a huge air bubble stuck in my front rad as it's ports are located at the bottom and this was causing abnormal temps in the GPU (probably due to low flow as the Poseidon is pretty restrictive), even though I did turn the PC upside down and shake it looks like doing it for a second time fixed the issue.

I do agree that Kryonaut is stupidly expensive but as someone already mentioned it's a pretty good deal perf/$ wise.

ThrashZone Hi,
I can get nt-h1 locally 5x more more product for 3.us less than the small 1g tube of kryonaut
If anyone wants to use kryonaut feel free too.

It's maybe $1-$2 per application depending how much you use. Not exactly a massive hole in the budget for the type of machines people are building here. Spending an extra $1 to chop 1C makes as much sense value-wise as spending an extra $50 to chop 50C (which anyone here would do in a heartbeat).

I have a 5 year old tube that I cap and store in food saver. Still works just fine

Remember. Rated Shelf life is often times much lower than the reality. Specially with properly stored medicines 😛

broodro0ster Does it matter if the paste dries out if the temps stay stable? I don't think so...
I have tested Kryonaut back to back with Noctua NT-H1, and Noctua was 1°C better on a fresh application, but after 3 weeks, it was Kryonaut that took the lead.

Inital temps on a fresh application on the GPU were this:
Kryonaut: 42°C
Noctua NT-H1: 41°C

And after 3 weeks (same results after 3 months btw)
Kryonaut: 44°C
Noctua NT-H1: 45°C

So it's Kryonaut for me. It seems to be more consistent in the long run. And I don't care if dries out or become a stone. As long as the temps are good, I'm fine with it.

Idk, I change things often enough to never run into any issues. (Longest I’ve run it is 1-2 years)

You also become way less anal over time as you learn the hobby inside and out.


Solder pads are pretty cool too, just a PITA to implement. Most folks don’t like having to thermal limit the chip for reflow.

Someone will see a 1-2c change n freak out trying to point blame, all the while it was just 1-2c warmer in your office that day. 😛
Why only ultra? I'm on my second tube of pro and have been exclusively using that for my delidded cpus since 2014. But if ultra is better I wouldn't mind switching. I just like pro because of how thin it is.

Also MX-4 always migrates for me. AS5 beats it without fail after a few months for me. Not at first, but as soon as the application of MX-4 turns to nothing but mineral oil in the interface area it falls back. Maybe I mount my coolers too tight?

8 years for both MX-2 and MX-4, stated on the package for several years now, just checked mine and cross checked with the 2019 editions on their site, it's still the same 8 years. Speaking of which, I just opened a still unopened tube of MX-2 I had lying around for ~3 years and it's fine. I have experience with MX-2 and MX-4 and they last for several years. The MX-2 in my i7-3820 has been there for 7 years and is still going strong. The AXP cooler (also made by Arctic) that I put on a GTX 480 in 2011 came pre-applied with MX-4 and I ran that card for almost 3 years without any temperature problems.

I Just checked a new 6 year old tube of MX-4.
The very edge of the paste was hardened (around the nozzle) but everything else was just fine. Not using it, though.

Also I've had no problems with Kryonaut. Yes it is a little hardened in the 9900K compared to brand new, but there was no difference between a 2 week old application and a 3 month old application. Temps may have worsened by 2C or so from completely fresh, but remained stable afterwards.
