I tried a simple bang-bang controller (LM35 temp sensor+comparator+pass
transistor to drive a small fan) with the LM35 taped to the center of a large
finned heatsink. The FE-5680A+heatsink are sitting upside down, so heatsink
fins point up. LM35 leads wired with 34 gauge wire, which is taped alo
Well done.
You have answered a couple of questions for me. The heat sink inside is
small so its easy to see why all sides of the case should be close in
temperature.
Like you in tinkering, I attached 4 reasonable size heat sinks with the
case off and noticed I could drop the internal heat sink to 1
