    My HP 7900 computer's case fan started making noises at time and I purchased a new case fan to replace it. The problem I'm having is when I went to change it, the plug on the new unit, although being a 4 pin like the old one has a narrower slot on top of the plug than the HP plug and will not fit! Is this some stunt that HP pulls to force you to buy replacement parts from them ? If so, does anyone out there make an adapter for this situation? Or does any of you have a way around this problem ?

    do the 4 pins of the new fan plug match spacings with the motherboard connector?

    They appear to match pretty close to what the old one is, with the exception of the mentioned slot. Had the thought that I might take a dremel tool and sand the slot on the new plug flat. What do you think?

    If it was me, I would match the new wires to the old plug, cut, slide some heat shrinkies on and solder.

    I wouldn't as just more work. just put a mark were the new location of the key is so don't put the plug in reverse.

    I thrive on work: I'm capable, resilient, inspired, efficient and off my medication.

    That's my method also.. some of my cases are like Frankensteins monster.. almost every wire has been changed at some point.. especially those with Dell mobos fitted at some time

    It's when you get to having split cables with "options" that life gets fun..;)
