I have a intel 4790k Haswell. It's a newly built computer and usually idles around 30-35 (base on core temp and speccy.. However when I have the program zonealarm and go into a reading manga site, It can spike to 70 and go back down to 40-55. I made sure the thermal paste was put on correctly (used a metrocard and spread about a half a dime thin layer) and the stock fan, I hear the click and then turn the knobs to lock it in place. Because of this I didn't start gaming yet, should I order a better cpu cooler?.
