Review: Sensor don’t work - So got system all wired 100% works great! Was a dummy for a second and thought it didn’t work but works great … don’t forget to ground the adapter!
Review: Sensor had slight issue, but seller solved my problem. - Adapter is great quality. Only issue is have is the sensor seems to have an intermittent connection issue. The blade connector coming through the black resin is loose and slightly moves causing two issues, a coolant leak and the fans to kick on and off. **Edited rating. The seller quickly resolved my issue and sent out a replacement temp sensor to fix my issue. Thanks again!
