The hotend fan mostly blows below the Dragon Ace's heatsink significantly. Most the airflow hits the upper silicone sock. This reduces the cooling capacity that the 2010 can output to begin with.
Anthead with Dragon Ace is unusable for me as it quickly clogs once the printer has hit a chamber temp of at least 50C. Other toolheads have not posed that type of issue.
Image for reference. You can see the the offset from heatsink to 'line of fan'.
