Razer Blade 15 Base (mid-2019) dropping fps in games

So since a few months back I have problems with fps drops when playing games like COD: Warzones or World of Warcraft. First I thought it might be cable issues with my 3 monitors, but I have since ruled that out since Ive tried playing with only my laptop and the drops in fps still occurs. The drops are random and only lasts for a few seconds. Usually I am around 70-100 fps and then it drops down to 15-25 fps for a few seconds. Only to then go back up to the 70-100 fps. Ive installed Afterburner and Intel ETU, which shows me that my gpu usually is around 85-90 degrees Celsius and my CPU is around the same. Ive bought a cooler tablet that I now have my Razer on to help cool it down, but honestly I dont see any effect from it. The same degrees happens with or without it. Do you guys have any ideas on what I might try to fix this and what it might be cause of? Thank you!
