Does this help boost cfm for ac infinity multifan s7 https://www.amazon.com/gp/product/b00jlv4bwc/ref=oh_aui_detailpage_o05_s01?ie=utf8&psc=1 ?

It does allow for increased fan RPM (speed=CFM) compared to a standard USB port, and it provides a 120V source USB port for equipment not otherwise equipped with a USB port. Its has a 6.6v dc, 1000mA output, 25% higher (V) than standard USB at 5v dc; I have no way to measure if fan speed is increased proportionally by 25%, but the S7 pair does run faster on the HI setting. DO NOT use this with other USB based devices as damage could occur due to the higher output voltage!!

Hi i have two fans and don’t understand what needs to be done plug them both in simultaneously. do i need a splitter? do ai need two adapters?

It only has one USB port depending on what fans you have you may need two the fan I have has a male and female usb plug so I can run them in a series or you could geta splitter I have ac infinity multi fan s3 series model #AI-MPF120A hope this helps

What are the exact dimensions for the mounting holes? (I need the distance between the centers of each mounting holes)

All your questions about the Multifan series should be here https://www.acinfinity.com/search.php?search_query=Multi+fans. If you need more information just call their Cust. Ser.

How many fans can you connect to this if you use a multi usb adaptor?

I'm running 3 fans with it; 2 have hi/med/lo controllers. There is a USB connection for a 4th, not used. I don't know how much total voltage you could pull if you daisy-chained indefinitely.
