Nexus 5X Heat (normal or problem?)

Hello everybody, before, I know there are several posts on the xda about the phone get so warm, but I think I have a different question. At this point in my country are about 35/36º Celsius, which obviously makes the phone warm up a bit, but i without open any application the temperature reaches 42/43 Celsius, but it will be normal or is a situation to worry ? I see quite a few posts from people saying that the mobile phone reaches 60º, the maximum I could get on my was to 48 and had several applications open and was playing a game. Like all others, the mobile phone is quite hot in the sensor zone and sometimes is hard to use, I even installed an app to close all applications to save battery and cool the phone. Therefore, it is normal but all phones warm up a little when they are being used aggressively, but it's normal after unlocking and without any open application temperatures reach 42/43 celsius? Should i send for warranty or not because this is normal?

Thank you in advance any help :good:
