is my 80gb ps3 fat can be hackable

hello guys i have got ps3 fat 80gb 4 usb ports so i wander if it can be hacked or not and also when i start it it takes few seconds then the fan runs with sound and gives high temperature so how i can know if it so dirty and needs clean and when i put disk the ps3 can't read it and can install itb hard disk in it. the model of my ps3 is (ceche01 mg)

thanks in advance
