I bought a Mugen lower temp fan switch only to find out that the NSX uses a different size switch than pretty much every other Honda ever. The Mugen switch is M18x1.5 while the NSX is M16x1.5. Once I found out the size I needed I started a search for a switch that would fit. That led me to a Mitsubishi sourced switch that turns on at 85 and shuts off at 80. So I went to pull apart today in search of one and found it in a 94 Mirage S, clipped the plug and pulled the switch, swapped it with the stock sensor, swapped the plugs, and it works perfectly. Kicks on right at 85c and shuts off right around 80 or so. Total money out of pocket, $5 for the part and $2 to go in to the pull apart yard, $7 total.
You can also get it brand new from any autoparts store for $20-25, it's Mitsu part number MB660663, but then you will have to find the plug somewhere.
Here is a list of all the vehicles the switch can be found in according to Rock Auto. It's usually located in the bottom of the radiator next to the hose.
