Would attaching a 80mm to 60mm fan adaptor increase the noise - if all by much?

Theoretically greater airflow over a smaller area should create a higher noise.

My plan is to use a WBK68 (version 1) - remove the fan - add a 80mm - 60mm adaptor and use the panaflo 80mm low speed fan at 5V.

Suggestions, comments? :?

In theory, yes. But in practice, No.

If we were dealing with much bigger air flow numbers funneling the air down and then pushing it through a heatsink would make more niose. You're basically making a whistle, if you think about it.

But at these airspeeds the flow's too low for the turbulance through the heatsink to make a noise, or at least to make a noise that we could hear. The reduction in fan noise would more than make up for it.
