How do I set ice on my Huawei?

Excuse me, could you please tell me how to set ice on my Huawei device? I've been trying to figure it out, but I'm a bit confused. I've heard that this feature can help cool down my phone, but I'm not sure how to activate it. Is it a built-in function, or do I need to download an app? Also, would setting ice have any impact on my phone's performance or battery life? I appreciate your help in clarifying this matter.
