1, the single 4CM fan model get a higher temperature than the 2* 2.5CM fan model, but also acceptable, and not find any error rate increase during the compare test. the ambient temperature is 25-26 centigrade.
2, the single 4CM fan model uses a 4200RPM slave bearing fan, made by SUNON. MODEL NO. is KD1204PFS3. here is the datasheet:
http://datasheet.octopart.com/KD1204PFS3-H-Sunon-Fans-datasheet-146198.pdf
3, 4CM fan model's noise is much lower than the 2 fans model.
4, the 4CM fan is fasten by 2 screw, you can change it by yourself easily.

Hmm I see. Well to me noise is no issue so I think I will replace the single 4 cm fan with 2 x 2.5 cm ones if I can find them somewhere.

By the way if anyone is wondering the USB to Serial chipset on the board is a Prolific PL2303 which can be found here:

This is necessary on Windows XP (and perhaps older) machines. I'm not sure about windows 7, but apparently the windows action center actually located the proper manufacturer and it even gives you a link to follow to download the drivers. Needless to say I did not actually install it on a windows 7 machine yet.

update: did some checking and apparently the link to the proper usb driver is located in the README file for the Tcl miner but not for the python beta miner.

Now the next challenge is getting the miner.py program to actually work. Do I need a specific version of python or any will do? JSON-RPC addon perhaps?

I know for linux this will be a lot easier but it would be cool if there was a guide for windows out there.

For now I think I shall see if I can get the Tcl version working at least.

notice that the 4CM fan i select is a low speed model. change to a faster model will sure better than even use 2 X 2.5CM fans.
the FPGA is -I temperature grade, and can run under 100 C core temp.

all the need files i'm updating them onto github.
