How to reduce the noise level at the miner.... 
I can snip the Fan too loud and use other fan? I have set off at 80 celsius. the noise level is crazy.

you can replace it with something like artic f12 pwn and set it at 50% speed, should be enough for cooling the miner

if you are good at it, you can try to lower the voltage to 5v, this will lower the fan rpm

but where can I connect externally to s5 I see a 4 pin connector .. but I do not know what is it for..?

connect it to the one were the previous fan was connected, if it is 2 pin only then you need to connect the fan directly to your desktop

maybe post a picture of that 4 pin connector

This is a molex to 3 pin adapter: http://www.amazon.com/Phobya-4-Pin-3-Pin-Splitter-Connection/dp/B007S3T4O0/

You can get 4 pin versions as well.  If you do that  you can connect your replacement fan straight to the connector.   It's a good option if your having trouble connecting the fan to the PCB.

I tried to put this out there on one side. went into full 3000 rpm but not enough, miner was 93 degrees and do not count ...
and on the other side some corsair fan ...
it did not help, miner overheats.
I think it's from the engineering point of view is very very  badly designed miner.
The need for water cooling in the price of $ 250 but the postage is too 200usd ...

but if they put that 4000 thousand speed fan for some sort of link a speed regulator, it would be a solution for smart people.
I had something like this before many years the custom fan and heatsink for the video card .. beautiful speed controlled fan. to 3000, for example, could be maintained below 80 degree S5
