You could always do this 👍😎   Works a treat.       Same both sides oem fan is long gone these are IP67 rated fans & the combined FPM is 50% more than the OEM fan & both suck air outwards through the rads. I have 90C thermal switch which resets at 80C. Works great. Plus if one fan dies there are 3 others still working.    Just needs a little sculpting of the outlet vents where they cross the fan frames. This is not visible from outside.
