I have a Sempron 2400 cpu and a MSI kt4A-mobo, mushkin 256 pc 3200 ram. At idle the temp for cpu is 49-50c and sys temp around 37c. Seems a bit hot to me. My case has two 80mm fans. One in back and one on the side. If I turn the one on the side to pull air into tower instead of out will this help lower the temp. Or is it a waste of time. Thanks id advance for the advice.
