Does the single fan on the 2'nd batch Icarus board provide adequate cooling to the fpgas? (compared to the dual fan solution)

edit: Also is the current fan sleeve or ball bearing?

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:

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.
