If it's getting hot, manually boost the fan speeds, or allow TG Pro to do it automatically to help keep the Mac cool and running fast. Get local or email notifications for temperature events along with full logging for further analysis. It's designed with security in mind. TG Pro is notarized and uses the Hardened Runtime.
Maximum current - amps - through a 12V circuit - related to size (AWG) and length of wire
Conductors in electrical systems should not be sized with voltage drops exceeding 3%.
2 0 Gauge Wire
For a 12V system the maximum voltage drop should be less than (12 V) x 3% = 0.36 V.
Conductor sizes (AWG) related to maximum current through a 12V electrical wire and length of cable - are indicated below:

Wire Gauge Design Procedure
- calculate total length of wire from source to device and back again
- determine amount of current in wire
- determine correct wire gauge in the intersection of amps and feet
Note! Wire size based on 3% (0.36 V) voltage drop in a 12 Volt circuit. Always oversize wires if voltage drop is critical.

Temperature Gauge Pro 2.33 | Mac OS X | 8 MB.
TG Pro is an essential utility for all Mac users with three main features:
• Check up on your Mac by viewing current and maximum temperatures recorded by each sensor. Choose between degrees Celsius or Fahrenheit.
• Tune the fan speed so your Mac can run cooler with manual fan control. Or is it the fans rotate at maximum speed automatic Boost when a specific temperature is reached.
• Discover defective fans and temperature sensors with integrated diagnostics.
Temperature Gauge Pro will also display a notification through the Notification Center or Growl when the temperature is hit or automatic Boost is enabled. Also, you enter all the information into a CSV file to graph in an external application. It works on all Macs, either a laptop or desktop computer.
