Yes, looks like temps, but you need to check what causing that high temps like Dust, lack of proper intake and exhaust system (Fans), also make sure if your PSU also getting proper airflow.
- My first doubt is airflow so check if your cabinet is getting proper cool air as intake and pushing hot air from exhaust.
- If your Fans, CPU cooler and other components are dusty then try to clean them.
- also make sure your cabinet is in cool place and PSU is getting cool air flow (from your name it looks like you are from India, and its hot, as its summer time, so if your cabinet is in congested place so remove it from there so it can breath cool air).
- Also look for GPU temps
