Hey, so recently I inquired on this forum about using a splitter to connect my front fan and my back fan using only one set of fan pins on my motherboard. The CPU fan is plugged into its proper set of pins, leaving both a three-pin back fan cable, and a four-pin front fan cable. However, there is only one other set of pins on the motherboard called "SYS Fan 1". Basically, I was told it would work fine, to plug the three-pin fan cable into the four-pin slot of the splitter, and to connect the four-pin fan cable into the three-pin slot of the splitter. I ended up buying the splitter, and it just arrived today. Problem is, while the the three-pin back cable fits just fine into the four-pin slot of the splitter, the four-pin front fan cable is just slightly to long to fit into *either* of the splitter's slots (they're both the same size).
Another strange part is that the four-pin front fan cable does not have the same sort of shape both the CPU fan cable and three-pin back fan cable do. It may be hard to explain through text, but they both have a slot that kinda lets them "slide" right into place into their corresponding pins. The front fan cable, however, does not, it's just mostly flat with a few small raised areas here and there. Yet, I'm certain it would still fit this way, the only problem is that it is slightly too long. I can provide pictures if necessary for further elaboration here if it's difficult for anyone to get what I'm saying here.
So, at this point, I'm not quite sure what to do. The only thing I can think to do at this point is to shave off one of the sides of the outer plastic casing of the splitter so I can give the four pin cable the little bit of extra space it needs to fit in place. Would this be unwise? If so, what should I do? I mean, the front fan is currently plugged directly into the power supply, but I've heard that this can potentially cause problems, and am strongly against leaving and finishing the build in this manner. There has to be a way to make this four-pin cable fit into the splitter.
Here are all the parts relevant to the situation:

Motherboard: MSI B250M PRO-VD Micro ATX LGA1151
Power Supply: SeaSonic S12II 520W 80+ Bronze Certified ATX
