Did you already decide on the 3M or EZDIY one? I saw the EZDIY is also sold by EASYDIY, upHere and in my local Amazon shop where it says the manufacturer is Thermaltake but they don't actually look the same (EZDIY/EASYDIY/UpHere vs Thermaltake).

Turns out they are actually manufactured by Deepcool but it'd be interesting to see how they perform in the long run.
