Why... why did you do that. As a COMPUTER TECH you SHOULD know that using a CPU without a properly pressed heatsink and thermal paste can permanently damage the CPU due to insane temperatures. You risked that badly.
That said, from your screenshot above your CPU runs at 133F (55°C), not 113F. 113F is fine, same as mine, but 133F at idle is definitely high, considering the upper temperature limit for that CPU is 144F (62°C). Which heatsink do you have? The one with less, thicker foils or the one with more foils but thinner?
BTW, I can't watch HD videos with my X800XT and same MDD as yours, which videos in which app can you play in HD?
