I manage several large simulation flight operations in Japan for my company and we consume a large number of cooling fans per year. I had incorrectly ordered fans that were not appropriate for my application. Josh at Coolerguys found the right fans for us, and in the very large quantity that we required, in no time. He arranged an immediate return and credit for the ones I mis-ordered and got us up and running immediately!
We're shopping Coolerguys for all of our business cooling fan needs from now on.
