Fans are behind the body when ground radars are located in the front and below.
You can tell from the wiglets and fans that this drone is not intended to be as stealthy as B-2 or drones without those features. For this type use it's probably enough to have optical stealth. In other words, avoid being detected by monostatic radars in specular reflection wavelengths. If the corners, surfaces and edges are not perpendicular to the incoming signal they don't send signal back to the radar.
