Dell G5 15 5587 Overheating Issue

Hello everyone. I recently purchased a Dell G5 5587 laptop and experiencing overheating issues. I had a bit of surfing on the net(Reddit, Dell Community Forums, Google+) and found out that many people experiencing the same issue. I found a solution to lower the temperatures by undervolting the CPU via Throttlestop and it actually helps. But I still get occasional FPS drops(every 10-15 minutes). It's like a minifreeze followed by a sound crack and it only goes for maybe half a second and everything goes back to normal. Anyone else experiencing the same thing? Is there any other suggestions to eliminate this problem? I turned off the turboboost and the issue has been resolved. However it effects the performance drastically. (Far Cry 5 in-game benchmark result: With turboboost average fps 76, without turboboost average fps 55) So deactivating the turboboost defies the purpose of having a gaming laptop. I am currently using a platform to elevate the computer and it does help with reducing the core temp however this minifreeze issue is still occuring. Also with the new BIOS update (1.9) dell power manager has a new Thermal management feature and I already set it for Ultra Performance. So I am not sure what to do. Thank you in advance.
