First water cooling 140mm rad

[R4NG3R]

so I'm doing water cooling for my first time and I was just wondering if I can use a 140mm dual rad and a 120mm single rad for my 4670k and my gtx 670ftw

As long as you've got somewhere to put the rads, you can use as many as you want. However, a 2x140mm rad could handle both the 4670k and the 670. More is better if you already have the parts though. I wouldn't buy an extra 120mm rad for that setup.
