M64 Fan Mod Update

Hey everyone I wanted to post an update to my previous fan mod post so as many people can see it as possible.

I went ahead and installed a pwm controlled fan, and I am pleased to report that it is controlled by the console and shut off when not needed!

For this next section of the update I unfortunately ordered too small of a fan by mistake (20 mm instead of 25mm), so I will not be including it in these numbers as it is not indicative of a proper result.

I wanted to compare the temperatures of an original n64 and a stock m64. Both systems were left in the same room at the same time for 3 hours while playing a game to allow the system temperatures to reach equilibrium. I then measured the temperatures with a laser thermometer.

Original N64

Console external temperature: 47.3 c

Console bottom temperature: 53.8 c

Cartridge temperature: 45.0 c

Stock m64

Console external temperature: 45.5 c

Console bottom temperature: 55.1 c

Cartridge temperature: 39.7c

So all in all the m64 is around the same temperature as an original n64 with the cartridge actually remaining a bit cooler.

Is the fan mod necessary? Given how close it is to a real n64 probably not. But if you want to extra protect your cartridges, a 25mm pwm fan will work inside of the system.

M64 Fan Mod

Now that the schematics for the m64 have been released there is an unused fan header on the motherboard.

I wanted to see if adding a fan would make a noticeable difference so I quickly threw something together.

The fan header is for a pwm fan, but I just used a DC 5v fan I had laying around.

Adding the fan made a major improvement to the system. It went from becoming thermal nuclear (artistic license) and the cartridge getting hot to slightly warm to the touch directly under the fpga and the cartridge staying cool.

The 5v rail is on at all times the system is plugged in, so the fan is always spinning. The next step will be to attach a pwm fan and see if the system's firmware is setup to control it.

Killer Instinct Gold Bug

Has anyone else experienced a bug where killer instinct gold will not boot if a controller is connected to the system?

Neo Geo Pad Button Arrangement Labeling

I have seen a few posts discussing how the AES plus pad has rearranged the buttons on the controller. While it is true that this has been done before on the mini pads to presumably make some games easier to play the plus pad has an issue I haven't seen anyone else mention.

If you compare an original pad vs mini vs plus, the plus buttons are actually mislabeled so the button colours do not match what they are supposed to be. ( Red = A, Yellow = B, Green = C, Blue = Yellow)
