Re: Incubator fan problem..
ok so the only concern that i have when you turn on the fan 24/7 your temp spikes. Well this makes me think that maybe you have temp variation and when you turn on the fan it is evenly dispersing the heat. And also i would recommend getting a thermostat like a herp stat that is not a on off type so when you set it to 89 it holds it at that temp. Thats just me personally. I mean you are taking all this time to raise and breed for these eggs. Why risk anything going wrong while your incubating. Replacing your thermostat like a herp stat should help you. Having the fan is key to circulating the air. If it turns on every 40 min then since heat rises then in that 40 min that the fans no on all the warm air is staying at the top of your incubator. Hope this helps a little

Where is the probe? You might need to move it around.
So your saying that the fan is getting really hot and you think that the fan is what is bumping up the temp? (just making sure I'm understanding you correctly)
If so then as I said before moving the thermostat probe might help.
Are you sure that you are supplying the fan with the proper electricity? (you most likely are just trying to cover all of the bases)
Also temp guns only measure surface temperatures, not air temperatures. Something to keep in mind.
Probe is hanging dead center in the incubator
And yeah I know that about the temp gun I was just saying. I've got the probe, another digital thermometer set up inside a imitation egg box, and a third digital thermometer hanging in the middle haha

You don't need a fan controller, just a decent computer fan and an old cell phone charger.

You had to have had hot spots since you weren't seeing that till your fan was turned on all the time, fans even out the temps, not raise them. My guess is all that heat was sitting at the top of your incubator since there was no fan to keep it moving. What kind of thermostat are you using? It must be an on/off thermostat which is not a good idea for an incubator, you don't want your temps to fluctuate and that's exactly what you get with an on/off thermostat.
Also, the fan should not create heat, if it does it should be negligible. Computers need the fans to cool them, using a fan that gets hot would fry any computer. Get a nice computer fan, a nice one only costs about $10, and wire it with an old cell phone charger, that will help insure that a smaller amount of energy will be transferred to the fan. And I would never run an incubator without a fan, that is a very bad idea.
I second this. This is how i have my incubator set up, and my temps hold almost exactly at 89. I would look into making some upgrades to it. Just to make sure that you don't have any of these worries any more.

Like I said I ran the power cord for my 120vac fan through a dimmer switch and fine tuned the output so it wouldn't heat up the inside of the incubator past what the thermostat was set for.
