I'm in Finland so I could use the extra heat... ;-)
But seriously, it's all about the noise. I am trying to build something that's as silent as possible, and since I am not using any processor-intensive applications I am almost certain that a passive cooler can handle the task, especially when we're talking about Haswell 4***s with a TDP of 65w. I am only concerned about whether the case (Node 304) will be able to: 1. Accomodate such a massive passive unit and 2. create enough airflow when not on the highest fan setting.
Of course, I can also just opt for an ultra-quiet Noctua which was my original intention, either NH-U9B SE2 or NH-U12S.
