I have the same CPU and mobo that you do and a collection of slot 1 CPU coolers on my shelf. The cooler in my box is a Global Win VOS-32. The Alpha may be a timy bit better but it is almost twice the price. My P3 600 is clocked at 841 Mhz and running SETI 24/7 never goes about 37 and usually is around 34 or 35 degrees
