Is the h100i (or h105) worth it for me?

I mainly am a gamer, though I am thinking about overclocking. I currently have a Noctua NH-U9b that has two 92mm fans constantly running at 1300 rpm (with my low noise adapter on it, it can go up to 1700 rpm with the adapter off, though its a bit noisy at that since it runs at full speed no matter what). With prime 95, my highest temperature was 57 (Celsius), though I could easily get it down to 55 by removing the front panel on my corsair 750D that restricts a lot of airflow. Would getting an h100i or h105 be worth it at all? I really like the looks of the coolers, though the price and rare chance of leaking still have me wondering if I should bother.

Will you notice a difference in terms of lower temps? Yes, definitely. On the other hand, if you find the U9b to be loud running without the voltage limiter, you will find the h100i to be a veritable racket. It is substantially louder to achieve that performance level.
 


I would be replacing the fans with quieter fans though. Do you believe that I shoud bother getting this just for looks, or should I not spend my money on one of these?

Well if you replace the fans with quieter fans you will also reduce the performance. So in that case all bets are off which will perform better.
As for looks, personally I think they are both ugly as sin so I wouldn't make a change for aesthetic reasons.
