My computer keeps freezing at times and i think becasue of this crappy stock intel cooler so i was planning to upgrade i had 30$ so i was wondering what would be a good cooler? I dont think I want that artic cooler 7 pro thing again it didnt like it to much. Im thinking about buying a zalamn 9500 off of ebay can you all tell me the difference between the 9500 and 9700 series other than the bigger fan? If there's no big difference ill just go with the 9500.
