Just took out my hyper 212+ with a push/pull setup to clean it.

Should I mount it horizontally(fans blowing up toward the top of the case) or vertically (fans blowing toward the rear of the case)? It was in the vertical position all along, but I heard that mounting it horizontally is better because the fluid/gas in the heatpipe does not need to overcome gravity as much?
