Hi vKMR,
I have added 3 bullet points regarding this issue below, hopefully this will help you solve your question.
1) First thing's first I would like to make sure that the site-prep guide has been provided. Make sure that this guide is followed and that you are current in compliance with the cooling related sections.
You will want to make sure that the back of the chassis especially is clear of obstruction including cables, if cables are not neatly arranged it can adversely effect your cooling capacity.
In order to make sure I understand at what point these readings are being collected please let me know where exactly these sensors are being placed front and rear.

2) To see all components temperature readings you can do the following, this will show you all components and if they are in an Okay state.
* SSH into UCS Manager
Fabric-Interconnect-A# connect cimc 1/1 (Chassis 1 blade 1)

3) How long has the server been up and running, and is this the only server having the issue? Is it constantly an issue or sporadic?
If it is constantly an issue (sensors show as NOT OKAY (gathered from step 2) and your server is not customized to run on high performance I would recommend opening a Cisco TAC case in which they may need to re-apply the heat sink.
If this assisted you please mark the post as correct so other members can help find these types of solutions.
