I have been utilizing my system for more than 3 years and it is having an Intel Core i3 processor. I am not having any consequences with the system functioning but from some days it has began acquiring overheated. I am not willing to invest in a new system recently as I only utilize the system for excel and tally. The processor acquires overheated later continuous utilize of 1 hour and so. I have asked few of my friends about this and they have advice me to upgrade the cpu air cooler, so I only needed to familiar which will be the excellent cpu air cooler for Intel Core i3 or is there anything that I can test out to remove the overheating issue??
