## Questions & Answers

**Q: Can one temperature sensor be used to provide input to two controllers?**
A: Unfortunately, no, you can't use just one sensor for two controls.

**Q: Can this sustain enough power to run two flex-a-lite 398 syclone black 16" s- with out burning up**
A: I believe so. I was running two 16" fans as well and had no problems.  I DID however burn up my alternator from lack of airflow by taking out the cooling fan.

**Q: Can the length of the probe's wiring be extended if necessary?**
A: Yes, it can. You will just want to make sure you solder the joints of the extensions.

**Q: Will this work with stock 05+ Silverado dual fans?**
A: This has not worked the right way for me. I now have my 2 fans set-up so they come on when I start my truck up. I hope you have better luck than I did.
