I recently bought XSPC RS240 kit and now want to upgrade fans. I’m looking for good performance/silent operation 120/140mm. I have included a few fans that I consider getting below. From all these which one would you pick? It’s no brainer that SilenX IXP-76-18 120mm got best stats on paper, but reading the reviews throws me off a little bit. What about Xigmatec eXtreme silent? I’m open to your suggestions. 1. 2. 3. 4.
