Yes. You pretty much just have to deal with it. You can buy extra faceplates from valve to swap out https://store.steampowered.com/app/1072820/Face_Gasket_for_Valve_Index_Headset__2_Pack/ , or pay a lot for VRCover's thing.

You could also try making a fan for your headset https://www.thingiverse.com/thing:3821762 . I don't think it'd help too much though. Get an AC for your room.
