It will definitely help you can use core temp app to monitor the temperatures. I have done some DIY and trail and error with and elevated laptop cooling stand or you may use items to elevate the laptop, You can start by identifying the exhaust and intake ports of your laptop by turning it 180 and using a piece of tissue to identify which vents are intake and exhaust. If its an intake the tissue will stick.
You may now proceed with customizing with fans that fit your vents. To simplify if there are two vents one for intake and exhaust you can experiment by getting a single fan that covers the exhaust and the areas that are affected by heat the most and turn the fan upsidedown to suckup the air from underneath it. You can elevate the fan by using long screws to elevate the fan. Now the experiments may begin. Once you have the ideal placement for the exhaust now you can move onto the intake.Gaming laptops elevate as much as possible with the biggest fans directed at the heat areas. Some work with fans blowing at the intake vents and some just dont. Depending on the inherent cooling design you're trying to address the inefficiencies in its design. YMMV.
