I recently made a fan for my still air incubator using a PC fan and a 5.8 volt AC/DC plug.
I put it in my incubator and it was working fine, but after about an hour I noticed that the plug was warm to the touch.
Is this something that I should be concerned about? I really don't wan't a housefire, but then again who does?
Is it normal for the plug to be warm?
Thanks
warm is normal. if you can hold it without being uncomfortable, then that's fairly normal. if it's hot or the wires are hot, then it's NOT normal.
the key would be to check the fan's amperage requirements and look at the power supply. if the power supply is capable of giving MORE amps than the fan needs, that's fine. if not, there's going to be problems. it'll either list the number as mAh, or Ah if there's an m, it's milli Amps (1000 mA - 1 Amp, .5 Amps = 500 mA)
computer fans are designed to run at 12v so as long as the power supply says 12v or LESS, then you're OK. less just means the fan won't turn as fast as it would at 12v. all of my incubators have between 5 and 9v power supplies because I DON'T want a hurricane in the incubator. LOL
