Been seriously thinking about running a second loop in my case for a NB and memory sinks only. Since my mem sinks are set for 1/4" ID tubing, I thought I might just put 1/4 fittings on the NB and run a single 120 rad for them. I know none of us guys want to say anything nice about "small tubes" , but I'd like a realistic analysis of temps on a small 1/4" loop like this. I'm obviously not going for world record wc temps but I'd like to keep that NB cooled and get more than 3.7ghz out of my system
