As good as the D15 is for my mild OC on 5820K, it is simply too big for placement of other components. I am thinking of going AIO and get rid of the D15. So what is considered the best performer in terms of AIO that will beat D15 in performance while still being quiet? I am seeing controdictive results from different review sites. Over here Predator280 seems to be the best, while some other site claim Corsair H110/H115 are the best. Really confused here. Thank you!
