Ended up breaking one of the small white pins on my cpu heatsink. They also seem to be really difficult to remove from the motherboard. It almost feels like with the amount of force you are bending the motherboard when putting these in.
*** these man. Just replaced my last heatsink after i cleaned the other one out and broke it while pushing it back in. Got a close call on this coolermaster TX Series Aluminum 3 when i bent one of the pins, but was able to tilt it back.
