I built a gaming rig in a Corsair 800D case. However, when the radiator and fan was mounted on the rear (inside) of the case, the case flexed just enough that the fan would scrape. (I had trouble telling if it was scraping the fan casing or the rear of the case itself.) I have resolved the issue with a new fan, and a better mount, but I was curious if anyone had the same issue, or a different solution.
