OK, so recently my tube of AS5 ran out. I also learned my CPU temps were actually a lot higher than i thought, sooo I need to reapply my paste, CORRECTLY THIS TIME! I saw that AC had released the MX-4 for a much more budget wise pricing compared to the MX-3, But.... AC doesn't even have the MX-4 product on there site. That's weiird, but yet they put the awards MX4 won on its site The review speaks for itself it is at a much lower and better pricing vs the mx-3 http://www.tweaktown.com/reviews/3383/arctic_cooling_mx_4_thermal_compound/index.html and better than the MX2. IT doesn't require curing either right? Another thing to discuss where do they even sell it? I can't find MX4 anyware. And last but not least... What's better than MX4 after looking at the review. Price wise of course.
