Yes unfortunately, it is sad that APPLE didn't support VP9 acceleration as I think the intel G7 GPU in MBA can support it.Well yeah, you're software decoding a VP9 codec video. That means it's all CPU. On a system seemingly aimed at brief bursty CPU utilization rather than substantial sustained CPU loading.
I suspect that blocking airflow over the CPU heatsink isn't going to accomplish the goal. And potentially would impact warranty on any related parts if you didn't clean it out thoroughly.
But give it a try and report back.
I don't touch the CPU so it's temperature hasn't been a concern - the bottom case temp is what matters to me.
BTW - thanks to codec "wars" between Apple and Google, plenty of videos on youtube will be in VP9 codec that Apple doesn't allow hardware decode on - so it's all in CPU, and thus you're using the MBA for a sustained CPU load -- I'd suggest either installing the h264ify chrome extension to force h264 video, or try Safari. Or if you insist on sustained CPU loading, probably better to switch to a MBP.
I tried the h264ify but last time I use it, it doesn't support 2K / 4K playback on youtube.

2020 Air Heatsink Modification Thread
Yesterday, while adding the copper shim, I was wondering if it would be possible to somehow connect the heatsink to the backplate and dissipate some additional heat this way. Of course this might make the it very uncomfortable to hold the MBA on the lap under load, but I still wanted to try...forums.macrumors.com
If I read your graph correctly adding the pad will help even without the shim.
