Buying becool is like buying a dyson vacuum, does the same thing as all the rest but thru advertising they brainwash you into thinking its some how much better and worth spending more. I live in the same town as becool, they use mostly china cores and source all there parts and just put them together. I to have a Griffin and it was $267 and will cool even the biggest motor. I have 2 fans and even the hottest days the second fan has yet to run. Griffin has a website but you can buy for less at other sites. There dominator series 31.5in wide with 2- 1.25 in tubes probably what you want. You will need to make top brackets to hold it, just buy some 1/8in aluminum strips at H.D. bend them and use the original top plate bolts. They do make exact fit if that is what you want also.
