Premix fluid suggestions?

[Vidar]

So for the past few years I've been using Mayhems X1 Clear. It's been great, and I'm happy to keep using it. But, I'm wondering if there's anything better that people recommend?

Better by what measure? I've been using X1 in various forms for over 10 years and never had a problem.

If it does what you want and comes in the colour you want then why change!

Why change? Curiosity I guess.

Better by what measure? Thermal conductivity, lower temps or maybe longevity of the liquid?

X1 has been great, you'll get no argument from me here but surely things have moved on a bit.
