Jtgrimes :
I have an ASUS Z87-Plus and corsair vengeance 8gb ram. I wanted to get an after market cooler and the Cooler master hyper 212 evo looked like the perfect one for me. The only thing is will it fit without blocking out those ram slots
If your RAM has 'cooling fins' the cooler fan will block the slot closest to the CPU.
There are a couple of options though.
You can put the fan on the other side, for a pull configuration.
You can slide the fan up a little to clear that first RAM slot
You can rotate it 90 degrees with the fan blowing up
