We study the amount of turbulent support injected by protostellar outflows in the NGC 2264-C collapsing protocluster. Using HERA at the IRAM 30 m telescope, we took extensive maps of NGC2264-C in ^{12}CO(2-1), ^{13}CO(2-1), and C^{18}O(2-1). We found widespread high-velocity ^{12}CO emission, testifying to the presence of numerous outflows in the region. We carried out a detailed analysis of the properties of these outflows, including a quantitative evaluation of the total momentum flux injected by outflows in the protocluster. We show that protostellar feedback due to outflows doesn't provide enough energy to efficiently support the whole NGC 2264-C protocluster against global collapse.
