At this point I´m just completely resigned that the cooler is either really really bad or my CPU is horny as f***. I tried mounting the cpu outside the case to be 100% sure the base is making contact and enough pressure, during the night (was chill idk probably 15°C max) even reseated the cooler twice with 2 different thermal pastes and changing the direction of the cooler / fans. Both attemps gave me same results, the so called "safer" spring system is a joke, simply because the screw have a short threaded lenght and they will never go further down enough to make use of the spring system. Basically i had to screw so tight (as i would be a mechanic) the base, in order to be sure have "less" space between the base and CPU and the screws would apply more pressure, nothing changed. So I´m here with a glorified 1Kg of cooper / aluminium and stuck at 4.0Ghz because not even my CPU loves me and i got bad luck because simply will not reached 4.2Ghz unless tha auto system decide to throw 1.475V YAY!!
