5 secs fact check: does data center use more electricity for cooling than for computing?

No.

Let's assume the energy used in datacenter are from 2 parts: computing(including all the power from the servers) and cooling.

We know that for a cooling system(at least a decent one), the energy need to move the amount of heat:

$W = qQ = T_{low} / (T_{high} - T_{low}) Q$

where q is the efficiency of the system, and almost always > 1 (only if the outside temp$T_{high}$ is extremely high already or we want to cool the system to super low temperature($T_{low}$); neither is true for data center)

so no, for all the electricity we use for computing, it all turns into heat, and to move that heat out, we always use less than that energy.
