Big NO to getting anything different. After 15 years, I'm attached to this ole thing.
I should edit the first post, but I'm too lazy. Currently, I have a XSPC EX240 rad mounted on the back of the case. This is a thin rad about 30mm thick. For the life of me I don't know why I didn't get a RX240 (unless they didn't make them at the time). So, I thought about adding capacity to the loop, the first thing out of my brain was add another radiator. But, after a bit of reflection, I decided to replace the thin double rad I have with a Black Ice SR2 U-flow rad that is 60mm thick (double my current one). In some of the reviews, this rad equaled or beat some of the triple rads. If I still need a bit more after that... well, I can always get a crossflow single for the lower front panel or maybe get a hybrid vid card (has both air cooling and AIO watercooling) abd put the rad for it there. I want to futureproof my setup.
