SP120s

This may be a stupid question but here goes anyways- I have the non PWM sp 120's quiet editions cooling my h100i but I am sadly lacking in control through link. Now,if I get the performance SP 120's but run them at the same RPM as the quiet ones will they be much louder?

Other than fan speed there is no difference in the fans. It's the increase in speeds from the quiet to the performance that gives you the extra static pressure, air flow and noise.

I have SP120 performance fans on my H100i, the 3pin (non-pwm) and at the same speeds as the quiets they're comparable noise-wise.

I actually do control mine using PWM. A forum member on here, Tealc, makes PWM converters allowing you to plug 3pin fans into PWM and control them as PWM fans. You can find his thread HERE

Now with the PWM converter and the curve I've set the fans rarely spin over 1400rpm so some people will probably wonder why I went performance. The reason being that IF my system requires it, the fans CAN provide more air-flow/static pressure.

Spot on mate. That is what I was trying to say,albeit badly! I am happy with the fans I have on max RPM as they are however they are permanently on full power and cannot go any further. I figured it would be better to have the performance ones and have the extra headroom should I require it. The fact I cannot alter fan speed dosn't really matter as such as I have them maxed anyways to cool my 4770k @4.6ghz but I would like the option of more cooling if or when I require it. Guess I'm just gonna get the PWM performance ones anyways so thanks peeps
