Since the original Fan was 120*120*48 which perform quite good but a bit noisy. (max setting - 1800rpm@78.31CFM with 32dBA).
Now We are gonna turn those fan into a silent.
120mm fan solution are quiet good but for silent solution, we'll need more than that. So we go for 140mm solution.
Searching for a suitable fan.........

The Evercool 140mm Red Scorpion!


FAQ
How to fit into the KillerWhale? It is 140mm not 120mm?
-Well good question, the Evercool had already figure out that problem, so they include a free 120-140mm Fan adapter.

But how silent could it be?
-Less than 22dBA, almost 69% of the original noise level.

With that noise level, the performance won't be good?Sigh....
-No worry, since it is 140mm and it turns 1400 round per minute (read:1400rpm) it move as much as flow as the original fan could.

Well, does it last?
-The bearing is Long Life bearing. Therefore it can holds up to 40000 Hours!

Then it must be damn expansive...
-Not at all, at least cost same as other 140mm fan. About RM35 only.

It there any benefit besides silent and better airflow?
-There is one that ain't very important but it is still prefered by some people. The evercool fan depth only 40mm including the adapter. Compared to the original 48mm, can save 8mm which provide more space (=less pressure=less noise/vibration) the intake the air.
