Alright I'm using the stock HSF on my i5-2500k because I was too confused by the Cooler Master Hyper 212+ installation and figured I'd just do it later. I had pushed the pins of the stock HSF into the motherboard (ASRock Z68 Extreme3 Gen3) before rotating the pins...which leads to my current dilemma. I was able to pull out all but one of the push pins, I use some force but it won't budge and I'm afraid of breaking the motherboard. I'm using the Cooler Master 922 HAF case so I can access the back of the motherboard but I'm afraid if I do anything from the backside, I will also break it somehow. Has anyone dealt with this before, or should I find someone to remove the stock HSF and install the Cooler Master Hyper 212+ for me?
