There are complex manifolds with reduced cohomology vanishing in arbitrarily high degrees. Namely, product of two odd-dimensional spheres admits complex structure coming from representing it as a quotient of $(\Bbb C^n \setminus {0})\times (\Bbb C^m \setminus {0})$ by diagonal action of $\Bbb R$. They are known as Calabi-Eckmann manifolds.

Easiest example is $(\Bbb C^n \setminus {0})\times (\Bbb C^m \setminus {0}) / (e^At, e^At)$, and it maps to a product of complex projective spaces by further quotiening, with fibers being elliptic curves. This map is the algebraic reduction of the manifold.

This easy example admits deformations of several types; for example, you can take different contracting flow instead of linear diagonal one. Most deformations do not have complex submanifolds at all, and have spectral dimension zero as "most" generic cooked manifolds.
