does anyone have any ideas which CPU Coolers are suited bettrt for my board?
I have a  Ga-Z77x-ud5-th with an Intel i5 3750K, not only is my heat sink too weak, but it covers  the #1 RAM slot..  my ram is Corsair Dominator DDR3 2000   
http://www.newegg.com/Product/Product.aspx?Item=N82E16820145330I looking at a  "Downdraft"  Noctua NH-C12P SE14 140mm SSO CPU Cooler   
http://www.newegg.com/Product/Product.aspx?Item=N82E16835608019 it looks like it has better room for the Ram, you can take off top heat sink  of Dominator RAM, I also read you can turn the this heat sink  and clear the RAM.  I am not so concerned that as I am about the Cooler working well with my CPU  
thanks
