It takes about 80 watts to heat up a liter of water 1° celsius. Global data centers used about 4.16 x 10^14 watts last year [1]. Let's assume we still have a lot more data centers to build so bump that number up 10,000X. Assuming every watt of energy is actually converted to heat and we moved every data center on earth underwater it'd raise the temperate of the oceans (1.3x 10^21 liters) about 0.01°C.
This is a very rough calculation and there's obviously nuances but the point is oceans are HUGE and water has a high specific heat. It's much easier to indirectly heat them with greenhouses gases.
Edit: I clearly need to brush up on my physics. Regardless the effect is still miniscule.
