I just build fresh system using i5-3470. the temp running under load is around 46-49C for 4 cores. Are those temps normal or are they too hot. I am using the stock fan cooler. Do i need to purchase another good cpu cooler? Please help me asap.
Under load those temperatures are absolutely fine. Nothing to be concerned about. Remember you are using a stock cooler so any aftermarket cooler which has better specifications than the stock cooler will be better. You only need to purchase another CPU cooler if your temperatures get beyond 60 degrees under load or you want a cooler which is quieter.
