I'm looking for the best closed loop liquid cooler that I can fit in my Phantom 410 tower with no modding. I don't want to have to drill anything out, etc. I don't care that much about noise, as long as it's not just ridiculous I don't think it will bother me. I'm looking at the Kraken X40 now, but I wasn't sure if there were any more that were better or had a bigger rad that could fit in the top of my case.
