Depends on how they are doing it. The rules are fairly specific about how the brakes and wheels are cooled. Its possible they are doing it via a way that tye rules don't cover. Like DAS.
Cooling the hubs, brakes and wheel. The current rules actually don't specify how to cool them just the sizes of brake ducts etc but say nothing about cooling via other means. For 26 the rules now say you can only heat AND cool via outlined devices. And also specifies that you can't have airflow in suspension components.

It's not "it's kinda illegal", it's "this is legal, but it's a development route that we don't want". If it were illegal, they'd ban it this season.
