I have mine blowing IN the AlphaPal8045 using an Enermax Adjustable, and get 48C/37C CPU temps when it's on dial is set to the highest it can go (3,000 RPM). Of course, I have modded my case which has another Enermax Adjustable sucking air outta my case slightly below the CPU/HSF (still very close to it, about 1 inch south!), so technically heat is probably being sucked off my Alpha out the back, while air is being blown onto it simultaneously. Makes for the a killer cooling solution, and if I want peace and quiet I just set the dial to 1,000 RPM if I want to watch a movie, which is still has decent cooling.
I'll test temps with Enermax Adjustable on Alpha blowing OUT, and see if temps rise or fall.
