ok than what should i do?
What you SHOULD do, is deal with the temps you have now, use the unit sparingly and try not to overheat it anymore than you already have, and then when you have enough money to afford a decent cooler, THEN you get one. If you get a 15 dollar cooler I promise you that it will perform WORSE than the stock cooler you currently have. At best you MIGHT see the same results, but it's doubtful.
What you CAN do now though, because that cooler has probably been installed on there for a long time (And if it hasn't, when was it installed) is get yourself a good tube of thermal paste (Arctic silver 5, Noctua NT-H1, Cryorig Cryopaste, Phanteks PH-NDC_02 and Cooler Master Thermal fusion 400 are all really decent, inexpensive options) and completely clean both the CPU lid and the cooler heatsink base with isopropyl alcohol and re-paste your current CPU cooler so it performs well again.
Most likely the thermal paste that is in there has been there for a long time, has dried and has lost much of it's thermal transfer ability. A new paste job every two years of so is always a good idea no matter what cooler you are using.
That's the only solution for under 15 dollars that has any chance of doing you any good. Otherwise, save your money and get a 25-30 dollar cooler down the road.
