a213mPumping out is good, because the less paste between the cooler and the CPU, the better. If most of it squeezed out, then your mounting pressure is good.
a213mDon't try to fix what's not broken. Why do you think you needed to replace the paste in the first place? Your temps didn't change.
Cool GTXI use MX-4, inexpensive, easy to apply, seems to last years What did the TIM contact pattern look like - did you see any voids ? What I'm getting at is the TIM only fills voids / surface defects. Now some CPU IHS are anything but flat, can be convex or concave from factory
ZoranCI need to replace thermal paste on my CLC360. I tried using Kryonaut but that fell on its face, temperatures were practically not any better with it than with AIO’s stock paste. When tried to figure out why and took off cooler I found very little (practically zero) paste left between CPU and plate in the center, vast majority of it was on the edges as if it was completely pushed out during mounting. As I looked deeper into this I found number of complaints about getting “pump out” with Kryonaut which, based on description, seems to match what I am experiencing. So I went and ordered different pastes to see if they will do better. MX-5, NT-H2, and KPx are on their way. In the meantime I would like to hear experiences others have with this topic, which pastes you consider best but they don’t exhibit “pump out”?

Temperatures should've improved over the stock AIO paste.
jasoncodispotiI can’t speak to the exact issue you had or did not have. However I will say that I am not a fan of Kryonaut... I have tried using it the past and found it to be very dry directly out of the tube and thick. So dry and thick that it was very difficult to apply and get even application... I tried multiple tubes thinking I just had a bad tube and each tube was the same. Obviously Kryonaut comes highly recommended by many and is generally considered the best in the market... I chalk my experience up to my poor application skills and not a fault of the product. That being said I don’t have this issue with other quality pastes such as NT-H1 or NT-H2 and find them to be a lot more user friendly during the application process.
the_Scarlet_oneKryonaut is not the best for ambient cooling because it is not designed with ambient temps in mind, it’s designed with below ambient, hence the Kryo (Cryo) part of the Kryonaut.
the_Scarlet_oneI have no idea why everyone went on the kryonaut phase to start with.
the_Scarlet_oneKPX is also not designed for above ambient.
the_Scarlet_oneYou should not have a layer of thermal paste after application. You want as thin a layer as possible between the IHS and the Coldplate. You didn’t mention your CPU, which one are you using?
the_Scarlet_oneUsing Kryonaut isn't bad, but it isn't as good as many other pastes out there.
the_Scarlet_oneI have used Artic MX-4 for many years. When my tube runs out, I will try MX-5, but I do prefer MX-4 at this point. It works very well for my use case with watercooling and I have never had it dry out. I always spread my thermal paste myself, and MX-4 has always been incredibly consist:...I do want to say, you will likely see close to the same temps on all of the pastes. Your cooler may slightly adjust the fan speeds to keep consistent temps or something, which can be very hard to detect.
ZoranCthe_Scarlet_oneUsing Kryonaut isn't bad, but it isn't as good as many other pastes out there.I'm starting to realize there are things about Kryonaut that haven't been mentioned in those reviews. Which pastes you would recommend for water cooling at ambient temperatures?
the_Scarlet_one4:50 I show how I always apply the paste.
the_Scarlet_oneI want to try it, but I bought a big tube of MX-4 a couple of years ago, and haven’t run out yet lol.
DEJ915I had kryonaut scratch up some of my cold plates so I switched to Gelid GC-Extreme which was rated well as well and had no issues with it so far.
ty_ger07Pump-out doesn't happen right away. It takes a long time. Months, or years (depending on the thermal paste).…Pump-out effect happens faster (in a matter of months) with thinner thermals pastes, in general, and the thick stuff OEMS use is specifically chosen to have reduced pump-out effect during the entire warranty period of the product (years).…When your temperatures skyrocket months or years later, THAT is pump-out effect in action.…If you saw this "pump-out effect" right away, it wasn't pump-out effect. If you use a lot of paste, squeeze-out right away is normal.
ty_ger07If you didn't see better temperatures, perhaps the original paste was similarly as good as the thermal paste you replaced it with. … It just indicates that the original thermal paste was good and you replaced it for no reason.
ty_ger07All the conventional pastes are very similar in performance. Perhaps you expected to see a change which didn't occur, and that is why you think something is wrong.…Almost always, when someone changes from one paste to another paste and sees "a 5 celsius temperature improvement!", it's because the old paste had been on there for months and had already started to pump out.

transdogmifierpaste being pushed out from the cold plate/IHS contact area isn't bad ...
ZoranCtransdogmifierpaste being pushed out from the cold plate/IHS contact area isn't bad ...Like I said, it is not some paste being pushed out that concerns me, it is that practically nothing left where it should be concerns me. If nothing is left then transfer will not be as good as it should be. That is what I felt is reason why difference between Kryonaut and stock was practically zero. Stock had nice even thin spread, Kryonaut was leaving me with practically zero.
HeavyHemiI believe you're misunderstanding the entire purpose of TIM. The LESS TIM between the die or IHS and your cooler the better. More TIM means LESS thermal transfer. Ideally you'd have a perfect machine match between surfaces. Of course that is not possible. So, TIM act to fill those micro voids in the surface to increased contact area and thermal transfer.
