Insta360 One R OverHeating

I'm using One R + SanDisk extreme pro (128GB)+ latest firmware (v1.1.43) over a month, 5.7k recording with 360 mod for 15mins making the camera to overheat like anything, I tried sticking a heatsink with two-way tape but still it doesn't make any difference, A camera OverHeating within 15 mins will definitely decreases it's lifespan.How to resolve this issue ?
