Question Case fans turning on and off when i start to play games

[Lightning2348]

Hey guys i just built my pc everything seems to work and i got windows installed and it seems to be good. My case fans seem to be doing something odd. When i play a game only my case fans will start to turn on and off. The longer i play the faster it turns on and off. The type of fans are the stock fans from thr deepcool case. I daisy chained them all to one syns header and maybe thats the problem but im not sure. It is four of them to as well any help would be appreciated.

First check total amperage of those fans, if all are connected to one header it shouldn't total more than 1A.
Also check fan speed curve and temperature source for that header in BIOS.
