Depending on how hard your relay works, you might want to add a heat sink to it.
Q:During continuity testing with my multimeter why does my relay on the AC side not switch on?
A: The below info was found at http://www.crydom.com/en/tech/newsletters/solid statements - bench test an ssr.pdf
A multimeter determines impedance by injecting a small amount of voltage through it's probes into the circuit being tested. It then measures the current flowing through the probes and calculates resistance. Easy enough; Resistance = Voltage / Current! However, as we just discussed above, a solid state relay’s output turns on by “stealing” a bit of voltage from the AC mains in order to supply current to the gate of the SCRs. Simply put, if the AC mains is not connected to the relay then the output cannot turn on. Since the voltage and current produced by a multimeter is not sufficient enough to turn on the SCRs, the output of a solid state relay will remain in the off state; even with the input signal applied. As a result, SSRs will sometimes fail an incoming inspection because the engineer expects to see a significant change in the output impedance when they turn on the relay.The most effective way to bench test a solid state relay is to construct a simple test circuit consisting of a DC power supply or battery (a 9Vdc battery will work fine in most cases ) and a 60W or 100W light bulb.

Brass standoffs are essential components in electronic projects, particularly in applications where circuit boards need to be securely mounted within an enclosure or chassis.
Here's how they are typically used:
Board Mounting: Brass standoffs are used to elevate and secure printed circuit boards (PCBs) within an electronic enclosure or chassis. They provide a stable platform for the PCB, preventing it from coming into contact with conductive surfaces that could cause short circuits.
Mechanical Support: Standoffs act as spacers between the PCB and the mounting surface, ensuring proper ventilation and preventing heat buildup. This is crucial for maintaining the integrity of sensitive electronic components.
Isolation: Brass standoffs help to electrically isolate the PCB from the chassis or enclosure. This isolation is essential for preventing electrical interference, reducing the risk of noise and signal degradation, and enhancing overall circuit performance.
Easy Access: Standoffs facilitate easy access to the PCB for maintenance, repairs, or upgrades. By raising the board above the mounting surface, technicians can easily reach components and make necessary adjustments without disassembling the entire system.
Vibration Dampening: In applications where vibration is a concern, brass standoffs can help dampen vibrations transmitted to the PCB, thereby reducing the risk of component failure or solder joint fatigue over time.
Grounding: Depending on the design, brass standoffs can also be used as grounding points for the PCB. By connecting the standoffs to the ground plane on the PCB, they provide a convenient and reliable grounding solution.
Overall, brass standoffs play a crucial role in ensuring the structural integrity, electrical isolation, and proper functioning of electronic systems. Their versatility and reliability make them indispensable components in a wide range of electronic projects.

How to use
The Fan controller should be connected to the first 6 pins on the header where it uses 5V, GND and GPIO 3 (see images).
To automatically cool your Raspberry Pi when it starts to warm up, add the following to your /boot/config.txt and restart the Pi. You can change the value to make the fan turn on at different temperatures too:
dtoverlay=gpio-fan,gpiopin=3,temp=80000
