It is not snake oil. I was running AnTuTu 3Dbench 6.1.1 (my favorite version BTW). Normally FPS cuts in half after 2 or 3 runs. With this it stayed relatively stable at full speed or near full speed with a fluctuation of only 1-2FPS no matter how many times I ran it. Also, scrolling through video in my favorite video trimming app feels smoother and looking at CPU speed you can clearly see it is using higher speeds more! After the video was recorded I put the fan closer to the tablet to further improve cooling. I wish I had a better adapter instead of my puny 1200mA (14.4W when set to 12V for the fan) universal adapter since the fan needs 36W to run at max speed.
