Toshiba overheating

[Mamut0o1]

Good Morning all,
I have aToshiba laptop that has been overheating. It would take forever to boot and then it will shutdown. I noticed the fan is working fine so I opened the laptop and cleaned it, it had a lot of dirt inside. Now the laptop does not shut down but stays in around 48C to 55C. Is that temperature too high?
since I remove the heatsink do I have to apply more thermal paste?

please let me know if adding thermal past should improve cooling,.
Thank you!

Hi there, that temperature is fine for a laptop. Everytime you remove the heatsink it is necessary to apply thermal paste. Only because of the paste the heat is transfered from the CPU to the heatsink. Good luck.
