Unannounced Arctic MX-5 thermal paste spotted
The compound series has taken legendary forms by now, as everybody recognizes it. However, previously undiscovered Arctic MX-5 thermal paste has been spotted, and it seems a new revision is to be released soon in the form of MX-5.
Arctic itself hasn't announced MX-5 thermal paste, but if you look around for a bit, you'll notice it's already listing at Amazon in some countries. A 4-gram tube sells for roughly 15 EUR/USD. Unfortunately, there are no details available about thermal conductivity or viscosity. The new paste would last eight years after application, similar to MX-4 and MX-2 variants. MX-5 is metal-free and non-electrical conductive.
MX-5 thermal paste will be on sale from March 15th, and that's 10 years after the MX-4 thermal paste release.

I have a d15s
like I said,there was no problem on dc1
Nevertheless, it cant happen like that unless the situation is as described.
If DC1 is pretty thick and sets in place quickly, that might be why you see it as an even spread, but you can be sure the paste will be deeper at the edges still.

maybe I overtightenerd my cooler and dc1 took it better
should I leave 1/4 of a turn next time ?
or use the cross/lines method instead of a drop in the center

Stick to the recommended (or as sensible as can be) tightness for your core and cooler.
Its ok, actually preferable, for a curved core centre to be in contact with the cooler, as happens with thinner pastes.
Tightening a lot beyond that could crack it though.
Before I knew about this I did some incredibly tight heatsink mounting and didnt suffer any issues, but that doesnt lessen the risk.
Every new core and each manufacturers cores can have a different construction + ability to withstand overtightening, go careful.
As long as the whole die has paste on it, except perhaps the area touching the heatsink, you cant do better. Always apply it to the curve centre though, it will spread naturally.
You cant change the eventual dispersion of paste by applying it differently, only affect whether the core gets well covered which seems like it was so no worries.

Would be nice to test Arctic MX-5 vs Thermal Grizzly Kryonaut Extreme vs Kingpin cooling KPx
