H115i Platinum Problem

Yesterday I replaced my old H110i with the new H115i Platinum.

But I immediately found problems with the AM4 coupling system and performance.

With the old H110i I tightened the screws (with my fingers without a screwdriver) until they lock, instead with the H115i Platinum the screws do not lock (they become hard but you can always turn them with your fingers) and if I continue to tighten them the screw clips are released from the bracket installed on the motherboard.

I tried to tighten the screws until the pump no longer moves but I have temperature problems.

Idle temperatures are the same 33 ° C / 40 ° C, game temperatures are slightly higher than 2 - 3 ° C, benchmark temperatures are much more higher + 10 ° C.

For example in cinebench R20 multitred i lost 500 points, in single thread the points are the same.
