Not the most recent Version 3 though I suspect the problem would still be the same. It was mounted whereby the fan blades were 5-10mm away from touching the fins/core. This was per the recommendation of Spal and another OEM fan manufacturer we consulted with. So I think you're saying the fan housing should make contact with the core. I'll argue that with a 1 fan configuration, no shroud, in a low speed situation, you run into this problem in the NSX (see diagram). The OEM end tank configuration, which I eluded to the previous post, has the problem I tried to illustrate in the diagram below. The arrows represent water flow and water temp.[ATTACH]107317[/ATTACH]
