A:AnswerThe product page for that case says it will accommodate a 360mm radiator, so there shouldn't be an issue using the H150i Elite LCD XT unless you wanted to add 3 more fans for push/pull.

A:AnswerI was getting this when I had a bad motherboard and cpu. Once I got the replacements parts. The red triange with the explanation mark went away.
A:AnswerI noticed the same issue with that smaller box having the 240mm highlighted while the 360mm was not selectable.
If the main text shows this -
" CORSAIR - iCUE H150i ELITE LCD XT 120mm Fans + 360mm Radiator Liquid Cooling System with IPS LCD Screen - White-"
Then you should get the white 360mm. It worked for me at least.

Yes, there is pre-applied thermal paste on the copper cold plate to ensure equal paste distribution and easy installation. If you have any more questions or concerns, please feel free to reach out via support on our website and we'll happily assist you.
