Might take a look at this company. I have not used them - but their product seems pretty "robust" and they have various types of sensors if you just ask.
Having said that --- I wish CarlC -- AKA mister VAPORWORKS would produce a robust PWM system for us!!
I had this controller, I installed it, Had problems sent it in to Painless and finally after 3 weeks called them to see what was up. They said they where changing a few things.. I received it back and It had new setup instructions. Flip the switch up and hold the red button for 3 seconds. It worked a couple of times then wouldn't work right again. I called Painless (Pain in the azz) and they said that if It was there fault they would warranty it. If not it would cost me $160.00. So I shipped it back to summit and they refunded my money. GW said that I should go with relays, I ordered two relays and trigger them with a ground from my holley hp ecu at desired temps. Works like a charm.. So not saying not to try it if you desire, Just telling you my experience with it. Good luck

If you have a Holley HP, all you need is the C6 Corvette fan controller. The Holley HP can be configured to send a PWM- signal, which the C6 controller is looking for. It works like a charm!
I made a video a while back showing how it works with the Dominator ECU, but it would be the same for the HP.
The biggest advantage is that there is no big surge when the fan kicks on and it only runs as fast as it needs to to keep the engine cool. I rarely see more than 50% speed.

I did look at that option somewhat Andrew, That is pretty sweet setup. However at the time It didn't seem that the main plug for the pwm controller was available. How did you terminate your wires to this end? I also am running 2 11 inch spal fans. I was under the understanding that I would need two pwm controllers. If I was to do It again I may try the corvette fan controller. What fan setup are you running?
The holley ecu's are pretty nice pieces when it comes to doing custom things such as this. I was over it and wanted to move on, to the next thing on the list and that is why I went with the relay setup. It was a simple solution. Thanks for the reply and the video. I will keep it in mind on the next project.

Correct me if I'm wrong and things have changed since I purchased about 3 years ago but my Vaporworx controller is made by DC Controls. DC Controls also makes a nice PWM controller, one of if not the first PWM aftermarket unit to the market that I can recall. I've installed 4 of them over the years on friends cars and none have ever had an issue.
However, as the OP mentioned, he wants a thread-in style probe and DC only makes them with a dry-style probe for direct fin contact. While I'd also prefer a thread in wet-probe for cosmetics in reality DC's dry fin contact probe works *extremely* well and the unit is very accurate and repeatable. I'll let the fin-probe slide because the rest of the unit works fantastic.

Check out the new Derale PWM fan controller. I can attest to the robustness of the design and function ;-)
It has a screw in option for the sensor as well.
What can also be done with excellent results is to take the DC Controls press-in sensor, remove the covering, and epoxy it into a fitting. On the Camaro an old temperature sensor was gutted so only the brass housing remained. The sensor was then potted into the sensor body. A 3" pigtail/plug was added to make installation easier. Has worked flawlessly. The sensor is small enough to fit in quite small NPT fittings as well.
