Need help with cleaning my laptop

So recently I noticed that while gaming my laptop’s temp around 75-80. I want to clean my laptop fans and replace the thermal paste but I don’t know how and I don’t have right tools to do it. Should I buy a kit or any place to clean it up for me? If there is any place, can you guys tell me. Thank you!
