If it's set up as a puller it's possible with your shroud that when your speed increases you might be experiencing deadheading and or cavitation. If you look at Spal or Becool you will see they put in rubber flaps so when driving they open up to pass air through but at idle they stay closed do to the fan pulling air. Here is Spal's PDF on complete assy, note flaps run across top and bottom: http://www.spalusa.com/pdf/30102119_SPEC.PDF#view=FitH
Here is individual flaps:SPAL USA
