Im trying to get an order in before I leave to replace my dead 1900+ and was wondering which proccessor runs cooler: Athlon XP 2100+ or XP 2200+ or is their no real difference? I will be using a Coolermaster DP5-7JDIB-OL heatsink ( http://www.newegg.com/app/ViewProduct.asp?description=35-103-408 ) and dont want the proc overheating at all when its going to be under constant use 24/7 for my server. Please respond as quickly as possible for I dont have much time. THANKS!!
