I'm using the stock cooler with new Slip Stream case fans and wanted to get some opinions on some temps I received running an Intel Burn Test. I ran 15 passes on maximum with full RAM (8GB). The highest temp received was 85-degrees C on one of the cores. The others maxed out at 83-degrees C. Are these suitable temps for a stock cooler? I'm asking because I recently had to reseat the cooler after moving my PC. How much benefit should I expect to get from an aftermarket cooler? I was looking at getting a Noctua NH-L12, but wasn't sure if the $60 would be "well spent".
