It takes more work to avoid salt buildup, but you can evaporate saltwater as a place to dump heat, and we aren’t gonna run out of saltwater any time soon. 'Course, only so many places have saltwater access.
EDIT: You evaporate enough water for cooling, you can increase rainfall somewhat in the local area, which boosts crop growth measurably. I remember reading an article about nuclear power plants that use evaporative cooling producing that effect.
The growing prevalence of clean energy raises the question of possible associated externalities. This article studies the effects of nuclear power plant development (and, as a result, the increased amount of water in the atmosphere from evaporative cooling systems) on nearby crop yields and finds that an average nuclear power plant increases local soybean yields by 2 and corn yields by 1 percent.
The problem with using salt water isn’t salt buildup, it’s that it’s corrosive and will drastically shorten the lifespan of any equipment exposed to it.

Also, good luck sourcing salt water in Illinois.
You don’t pipe salt water through the data center. You have a heat exchanger that touches the salt water.
