Fortnite fps slow

[Panthercolin]

I have a GTX 970 MSI 4 gb I just rebuilt my pc and added a new water cooler for the cpu I have which is a I7-4790K and I have a MSI Z97 5 mobo and 16 gb of ddr3 ram so I should easily be able to play Fortnite on high settings with a stable 60 FPS but ever since I rebuilt my pc it’s been going from 60-40fps and it’s concerning me. I did add another moniter to my setup I now have three 144hz 1 ms response time moniters hooked up to it. Any ideas on why my FPS is now spiking? Also whenever I use obs to stream my frames drop to a consistent 40 fps. I have changed in game graphic settings and they don’t seem to change a thing. Any ideas on why my FPS is spiking and why when I stream it’s at 40 FPS thanks

Are you playing on all 3 monitors, and what resolution are the monitors

Maybe your CPU is thermal throttling because that could play a big role in it let me know what CPU fan you have

Unless you were referring to the Rad fan?
