Processor Air Flow

post #1 of 4
Thread Starter 
I was wondering if the fan on top of the heat sink blows the air down toward the processor or pulls the air up away from the heat sink. I know I could just put my hand by the fan and tell but with all the other fans it makes it difficult. To me it looks like its blowing air toward the processor, if it helps I have a cheap mass cool heat sink and fan. Thanks.

It definitally blows towards the CPU. This allows more cold air to get between the fins, vs sucking hot air out.

It blows air towards the CPU. In my case, I have a fan that brings in fresh air directly to the CPU fan. The air is then blown out of the sides of the heatsink. (This senario is true only if the fan is mounted directly on top of the heatsink)

Thanks for your help my processor stays much cooler when my 80mm side case fan is blowing toward my heat sink and processor.
