Why a fan in an incubator?

[MeepBeep]

would it decrease my hatch rate? How would i install a computer fan> Where?

***NOTE NOT ALL COMPUTER FANS HAVE THE SAME COLORED WIRES***
So some trial and error might be necessary, but generally black and red are the ones you want, if no red look for black and yellow... Blue and/or yellow are usually not connected in this application...

post your next model as soon as you can!!!

Or at least your plans...

What do you think caused that low hatch rate?

Depending on the size of your incubator you may want one or more fans. As previously said it keeps temperatures more even thru ought the incubator. I have (4) in the incubator I built. I placed one in the bottom rear which blows upwards, then at the top rear of cabinet I have (2) blowing the air forward. I then have (1) blowing the air from the front top of cabinet downwards. This all gives a nice circular motion and my temps are very accurate at 99.3 to 99.6 . My cabinet measures 26.500 tall x 23.00 deep and 17.00 wide. Bottom is first photo, top is second Photo. Mine are 110 volt, But you can choose 12 volt and use a old phone charger or charger that supplies proper voltage. I have my fans on (3) circuits in case one fails. Heaters Coils/ Elements are in front of the top pair of fans behind humidity tray. I have a four inch gap at top rear of cabinet so Air can make it up behind the fans.

2.Little cage like thing is where light bulb goes (60watt) And (aluminum foil) back and front of cage.
3.adding rocks
4. WHERE TO PUT THE FAN!!!

In that design I would put the fan directly above the light blowing down, and just a bit out...

But you said it is better to have it over the eggs wouldn't that go under?

Also, I tested my incubator without a thermostat and turned it off when it got to 101 degrees but then it kept going up to 104 then I opend it up and humidoty and temperature went down... What do I do to fix that after the thermostat turns the light off... will thr fan take care if that?

I said IMO it's best to pull the air over the eggs, but IMO that isn't really applicable in your design as the light is so low and could potentially 'cook' the eggs closer to it... To tweak your design make the cage a little bigger and put the fan in front of the light so it pulls the air over the eggs and blows the hot air into the back wall where it will fan out...

If you put the thermostat on the opposite side of the light from the fan the temp should not climb after the light goes off...

where should the wholes go and ugh its so hard controling humidity! Any help?

 

[MeepBeep]

IMO put some air holes up high and some down low...

As for humidity, I purchased a small USB humidifier on Ebay that keep in the incubator and can turn on after I open it to boost the humidity back up... Beyond that I took a rather large storage container about 8" x 8" and fill that with water, the surface area of that keeps my humidity pretty good... More surface area more humidity so find out how much surface area you need to keep your incubator happy...
