Hey guys , i m currenly buying all the components for my pc , and i have bought a z68 ud4 gigabyte motherboard , and i was wondering wich cpu cooler should i buy in case i want to 16 gb of ram (4 dimms) , i really want to stick with air cooling , and i like dual fans just like the corsair a70 . but since size seems to be an issue , i don't know wich one to buy. in caise I buy the a70 i will be only using 8 gb ram ?
