I have the NZXT S340 and I was wondering how I could make my system cooler. I could change out the stock fans and/or add two front intakes. But someone told me to not get any intakes. Right now there is an exhaust at the top and one in the back. They are also both 120mm fans. What is the best fan for a red and black them? Also I don't really care about the noise because I only wear headphones. And could I some how increase the current fans RPMS? I don't really want to venture into water cooling as well. I have a msi gtx 1070 and a i5-6600k non overclocked with a arctic heat sync on it.
