My case has a concern, I can not open it from the other side plate. So no backplate for me.
(Backplate is the term for reinforcements and metal nuts for the rear of the motherboard, provided systematically on all current coolers.)
With this TX3 EVO, an average size but's Light, which is modeled on the original pine Intel: just press on previously screwed pins, and poof, it's fixed.
Nothing more expeditious.
In terms of temperatures, I went from 85-95c to 24-31c ° ° games (League of Legends, Rift and Guild Wars 2). So yes, given the temperatures it was time to change the cooler ... (after 2 months of reflection: Simple cooler or backplate + crowbar ...?)
The thermal paste is provided. Do not spread a thin layer, smooth as could be.
================================
Furthermore, I understand that this kind of broad cooler had already twisting motherboard few special cases ... if only you had screwed your motherboard, there should be no problem.
