today, I recieved flyfan from Kingston, it's a 10$ usb fan, pic here. Half second setup, and start my mac as usual with the koolsink(a panel keep my lap and case seperated by certain distance) underneath it.
This morning before I reieved this flyfan, it took 10-20min to get my internal fan kicking in. The temperature of the video card die was 134oF ish which is the limit my Mac gets a bit noisy.
After I plug in the flyfan and properly oriented to let the flow pass from left to right beneath the laptop case surface and the space raised by koosink(I'll post a pic of final setup later). I can tell is the video card die is locked below 127oF and the processor temperature is 109oF. My AC is on, so i guess the room temp is about 88oF. The best part is that now the internal fan will never get chance to kick in then. lol, I havn't tried serious operation, just want keep this test as normal as I used to.
Ok, my gut tells me again that this time koolsink(pad) doesn't do much, 'cause I can't feel any temperature on it. It just keeps my lap away from laptop. And the windflow beneath laptop creates a heat boundary layer which benefits the heat transfer rate dramatically. Anyway the common sense is that circulation is alway good.
I'm pretty happy with this flyfan, the drawbacks are that 1) in a very quiet room, you still can hear the fan noise(which is anoying 'cause it is some non-consistant electronic noise), I can't find the noise level on their website, I guess it's around 10db 2) It cools my lap too :) Well, life is not perfect, what can I say?
