Koolance 3/8" (10mm) ID / 1/2" (13mm) OD G1/4 Threaded Angled Nozzles Pair (NZL-L10KG)
Koolance RP-452X2 res
Get rid of both of those... koolance is garbage, and will only cause you problems. You're doing a high-ticket build, and using Koolance parts... come on man!
And I'd just match the sets of radiators - go with an EK 140.1 and a EK 120.3 - EK's radiators are top notch, and unless you're running a SR-2 build or quad SLI, you're not going to notice a difference in temps with an XSPC radiator.
For the res, check out EK's Spin Bay reservoirs, or DD's new Monsoon bay reservoirs where it integrates a D5 pump into the reservoir itself - looks pretty sharp too!
