After removing these practically useless vents you might consider screening their holes so that some ventilation, however minor, may still occur, encouraged by the air movement generated by the new cold roof -- the Bernoulli Principle.

For example, perforated tiles near computer room air handler (CRAH) units may actually experience reverse airflow due to low underfloor static pressure according to the Bernoulli principle. High pressures also increase the typical air velocity exiting the raised floor, and can cause air to overshoot the servers in the bottom of the rack and increase mixing with the return air.
