MishimotoMMFAN-CNTL-UPROBE Adjustable Radiator Fan Controller Kit, Includes Probe Temperature Sensor, Black

Works great. I like that the temperature probe is not the kind that you have to thread into the engine. I used this for my AC condenser, and that would not have worked. The probe just inserts into the fins of the condenser, though I will probably have to apply a bit of glue or silicone to keep it from dislodging.Adjustability is great. It's difficult to right now though because it's only 79 degrees outside, and my AC doesn't really struggle until the outside temp hits 90-95, but using a thermometer gun, it looks like at the lowest setting, it would kick the fan on when the condenser reached around 90. I'll have to test and adjust that later.I had a problem originally because I tried to connect the yellow wire via a fuse tap. This was giving me negative polarity, so the fan never kicked on. Finally went looking for the radio turn-on wire, and used that. Problem solved. This is what the instructions and video say to do anyway, so I don't know why I thought I'd be smarter and use a fuse tap.I didn't use the override (green wire). My compressor is at the bottom of the engine, and the wires are on the top of the compressor, so it's not easy to reach. I think it'll be better without it anyway since this could mean more on/off cycles on the fan and controller. Also, the temperature probe works well and can be fine tuned, so I expect it will run exactly when needed.While troubleshooting, I called Mishimoto's support line and got a live person right away. I was told to email with pictures all the wiring setup - which makes sense since it's hard to describe it all over the phone and have them make a diagnosis. I ended up figuring it out before I needed to do that, but it's nice to know their support is available right away.Will update if any issues, but so far, I can tell this is going to work great. Separate review on the Mishimoto 16 inch fan coming later.

I was using a coolant sensor to control my electric fan on my 83 mustang. I could not get a reliable sensor that would work and not keep the fan running all of the time after getting up to temp. I purchased this kit and just adjusted it to my thermostat opening temp and it works great. Running down the highway the fan shuts off and lets air speed cool the radiator then when I get into town at lower speeds it kicks on and cools down just like it is supposed to !Great thing to use if you are running an electric fan.

Paired this kit with the mishimoto slim 12 inch fan.Works flawlessly! Instructions leave a bit to be desired. If you plan it out, watch a couple YouTube videos on this kit, and research a good ignition signal location for your application, you are set.The thermostat settings were surprisingly easy to set up as well!With a lifetime warranty, and a good reputation, I believe my vehicle is in good hands. Florida summer traffic jams are no longer a stress, and my AC seems to be working even better and cooler!

Let see wiring this up was no problem especially since I had better connectors, so I didn't have to use the ones they send. However, I feel that the main thing this kit lack's is a printed dial so you know where the temperature is set. It was a hassle to get both fans to run at the same time and to cycle as close as possible. Although I must say that's the only reason I gave it a 4star. None the less they work well.

Definitely pricey but it’s nice and has everything I needed to install the fan. The plug on the relay was a bit difficult to get snapped together and I wish there were numerical indicators on the temperature sensor adjustment but overall, a good buy

I'm so fed up with poor quality causing service failures in spite of my own best efforts.-fan control uses poor quality connectors and it is extremely difficult to plug in and align all of the blades while plugging it in.Blade's conflict with internal sockets.A simple plug in turned into an hour of fumbling around to achieve marginal results.Extremely disappointing.

i install two 6.5" spal fans on this controller and they work just fine. i emailed the company asking about if they will work with two 12" and and they do! amazing controller. also the sensor is easy to install and easy to adjust. the only flawless in the controller that the wires connector the plugs on the controller melted a bit, maybe because I'm keeping the controller in the fusebox and my v8 runs very hot. overall a great controller to buy for your fans

Relay failed. Engine overheated. This happened with a Mishimoto MMFAN-10HD fan after less than a year and only about 20 trips during that time. Their $15 charge (in the US) to fix it is more than the cost of higher quality relay than the one they use. I can buy 3 of the same relays on any website for the same price. If you get this or have it in your ride, keep spare relays with you and watch your temperature gauge.
