oil cooler and Fan view in-place
 

This is the stock oil cooler with a electric cooling fan in-place. I used one factory mount on top and turned the cooler just a tick to finish the mounting. There is a shroud as well. When the fan is on there is No vibration felt at all. The fan was off a Toyota Supra. http://members.cox.net/stdotjohn/Rx7...0001%20600.jpg

Umm...need a slightly better pic, John. Can't really see much in the photo. :)

Sorry the area as you know is tight , but there is a fan and a shroud in that tiny spot. Not a wimpy fan, it pulls a ton of air.

i see it.. it's bout 2-3 in. fan there.. is it diy fan or there's a core for these fan

I am not sure what you meant but the fan was used on a supra, there were two small ones on the driver side of the radiator its about 7 inches across the blades. I got them used for 30 dollars and had to engineer the fit of the brackets and shroud, test the fit and operation.
