I need 3 or 4 140mm fans, prefer PWM. I would like the start RPM range to be in the 5-600 rpm range. I plan on using 2 of them in the fron intake of my HAF XB Evo case, and possibly two more on my Noctua NH-D14 HSF. I currently have the stock Noctua's on that HSF, but I noticed that the fans seem to get a bit louder as time goes on.

What I'm seeing so far:

Or, would it be better to invest in a fan controller at this point. Thoughts?
 
I tested 4 different 140mm fans in my local pc-shop and I went with the Fractal design ones, they are low rpm and are silent at 500-600rpm. Corsair 140mm made a lot of noise and was almost double the price.
I would actually buy a fancontroller if you are using this machine for gaming/editing, as you might need to turn them up a few notches to get the best heat dissipation. (without fancontroller you will be stuck with the provided cable that lowers the voltage)
Variable fans are also easier to reuse in a later build. (wouldn't want any fixed 500rpm fans)
 
I would invest in a fan controller first to see if that fixes the problem for you. I currently have the NZXT Sentry 2 and think it is fairly good. The only issue that I have is that it does not give you a rpm just % of full power. It comes with included thermal sensors so you can let it adjust fan speed based on temperatures. Also it is fairly cheap at $30-35. There are some other controllers like the Reeven Six-Eyes but they are also more expensive. Check out NE or FrozenCPU to see what you may want then buy where ever is cheapest.

If the controller alone is not enough then I would look into getting some 140mm Cougar fans. They are very quiet all the way to full speed and no matter what orientation they don't vibrate or have squealing issues. They use what they call a hydro fluid bearing (HFB) but no one has figured out what it really means. Doesn't really matter though as it works.
