Daisy chaining a lot of fans, safe enough?

i have a new case coming tomorrow, and im going to be using 9 fans..i have two fan/RGB hubs that support 8 fans / rgb on each controller..

can i use both controllers with say.. 4/5 fans on each, then from the controllers connect the system fan header together and therefore using just one header splitting both controllers?

i assume that would be safe as the controllers are each powered by SATA connection anyway?

sorry about the explanation but its had to describe what i want to do.
 
Each fan header can only supply so much current - check your motherboard manual but 3 fans is the usual recommended limit.

As you are using powered hubs then this limit does not apply and you will be fine to use a splitter cable or daisy chain the hubs.
 
yes, check your mobo manual for how many amps each fan header can supply
most cheap mobos have 1A headers, mid-high end boards usually have 2A headers
AIO pump headers are usually 2A but speed control can be minimal or non-existent on these headers

you're looking for the peak current draw on the fan specs (usually also known as the start up current) as these will be well in excess of the operating current
if you're using high performance fans, the start up current can be as high as 0.4A...so even 3 of these fans can burn out a 1A header
 
Thanks guys. I have done some daisy chaining on them and all working fine.

As they are powered by SATA, the power draw is coming from there.
