As of August 2018 the State of California has changed the requirements of the “Prop 65” law. We now must list on our website any possible chemicals the can cause cancer, birth defects or reproductive problem.
As an example:
ABS plastic contains styrene
PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP)
electrolytic capacitors can contain Ethylene glycol
Brass can contain Lead
flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA)
Aluminum alloys can contain Chromium
To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching!
These fans get the job done. A ton of airflow without that annoying whine so many high-power fans have. They are loud, but that is to be expected, these are 30 watt fans. The weird connector they come with is easily cut off and replaced with the more common 4-pin Molex KK connector. These work well in a computer system, with the caveat there is no tachometer output. If your system has a fan-fail alarm, make sure it is disabled for connectors you are using these with. I was concerned about the 0-10VDC control voltage thing, but they also seem to respond well to the 12VDC PWM signal provided by computer equipment. If they burn out after a few hours, I know what killed them I guess.
