Okay, guys, I need some serious help. Purchased an AMD 6400+ AM2 chip to upgrade my CPU from my specs to the left. I also purchased a 550W Rosewill power supply, which installed no problem. When I went to plug in the cpu's fan, I noticed it was a four-wire plug, while my motherboard only had a three-wire outlet for the fan. It's booting fine (so far), but I'm worried my cpu could be in real trouble, as the fan may not be spinning as required (it spinning fine, but I'm not sure how fast it should be spinning for this chip). Should I even be able to boot with this chip if the fan isn't connecting to my motherboard properly? Any assistance would be greatly appreciated, guys. I'm scared as heck right now.
