what fmic kit is that, and where did you get it from? that fitment looks pretty tacky to me, or maybe it wasn't installed properly. most fmic kits will require you to cut a couple millimeter from the fan blades, if that.
most skyline temp guages sit on half if the cooling system is healthy. there hasn't been a fmic install that has affected the radiator flow bad enough to cause engine temps to rise and i wouldn't say it would affect much now that you've cut a majority of the fan blades.
i'll say as nismoid did to watch your temps during summer. especially when idling or in traffic, as this is when your engine fans are most likely to come on. if it poses as a problem in the future you can always upgrade to ford/holden twin thermos which are pretty cheap and pretty much bolt on or you can go with aftermarket kits.
