Building 8GPU cracking station question

[parmera]

This blower EVGA 11G-P4-2280-KRE (https://www.evga.com/products/product.as...P4-2280-KR) seems to be out of line or sold out for now, unfortunately. Going over the specs, I would like to understand about the differences between PNY and EVGA regarding the blower capacity / airflow directions and correct operation with 8 GPUs but not found a clue.

Would you know if these others 2 models below (Gigabyte and Asus) would work properly in a 8GPU build with TYAN FT77?
