I'm looking to replace the front 200mm fan with 2x140mm but not sure what to go for. I feel with 2x GTX Titans I need something with a little more static pressure performance so I'm not looking at getting the Wingboost 2 PWMs.
The only fan I've found which I think would do a decent job is the Akasa Apache
Thoughts?
Yep, that or the Bitfenix Spectre should do the job.

it has an old fashioned housing and is quite light and flexible, get the phanteks, it's much heavier and stonger/ far quieter
