## Questions & Answers

**Q: Can you view the data over USB?**
A: Thank you for your question.NO.The USB line just as a power function.Is designed for the convenience.

**Q: where can you place the sensor inside the CPU? Near the processor? or anywhere in the motherboard?**
A: It depends on what temperature measurement you wish to get reasons from. For CPU, you'll want to clamp it to the base of the heatsink and if really serious, use a little thermal glue between to sensor and heatsink for most accurate readings.  Depending on your heatsink, you may be able to place the sensor between the blades of the heatsink, just be sure to get the sensor to touch the base for best results.  If you want ambient temperature of internal heat of the computer, just connect it near the middle of the case not in the direct line of your airway ventilation track and don't let the sensor itself touch anything for best readings of internal computer heat.

**Q: How long is the temp sensor wire?**
A: About 3 '' or 36 inches

**Q: Can we put the whole unit in an infrared dry sauna?**
A: Mine are all at the tops of my aquariums so are subject to high humidity so I do not see why dryness would affect anything
