i am about to buy a new pc but now i have ran into a problem,
my case comes with 2 fans but my mobo only has one 4pin fan header.
case: Cooler master N300 (KKN1)
Mobo: Gigabyte GA-H110M-S2H
is it safe to use a y splitter to use both fans and will i be able to control the fan speed depending on the load?
 

if i clip one of the cables on the splitter that is for monitoring the fan speed and both fans are the same, is is possible to control both fans at the same time using only one fan for measuring rpm?
