Oh wait I actually found the post, bot said:
"MX-1 is what comes with the AF7 Pro. It is a very good thermal paste, in fact probably the best. The only reason it's not recommended more is because its harder to get and AS5 is more readily available.
The MX-1 is the reason that the AF7 Pro works so well."
I mistook his post and thought he said AS7 which led me to believe there was a Artic silver 7, but he ment the that cheap HSF most of this people on this forum go for cause its so cheap...and works good too... but not as good as a tuniq tower
