Incubator fans

Would it be a problem if the fans in the incubator run 24/7

I run mine constant when my bator is on, no problems at all but I do have them on a regulator to slow them down.

Do you think you would lose heat without the regulator

You should not be losing any heat with fans, they are just to circulate the hot air to avoid hot spots. If anything the fans will be producing heat themselves, the regulator can help minimize that heat.

Sweet thanks! Wouldn't turning your therm down just a little give the same effect

Correct me if I'm wrong but overall goal is to get temps to stabilize at about 89 right?

what speed fan do you guys use. I read a tutorial that says 220 cfm. I am having trouble finding one that's more than 90. that turtorial is for a full size fridge which I will be doing next year. for this year im doing a mini fridge. would 60 cfm be enough for that?

I am pretty sure it would have the same effect just have to be tweaking it until you have the desired temperature.

If you are referring to the tutorial that is a sticky on this section, the 220cfm might have been a typo. Instead a 220mm fan makes more sense because 220cfm would be way more air flow than needed and very loud. I used two 120mm fans for my refrigerator incubator and those are rated at about 75cfm. As for the 60cfm it does not really matter as long as you have the air flow to avoid hot spots.

The purpose of the fan is to circulate the air to try and keep the whole inside of the bators temp and humidity the same or as close as possible to 89 degrees and 100% humidity.

120mm DC fans are probably most common for use in incubators. They move plenty of air and will run 24/7/365 for years straight.

I have four 120mm Scythe liquid ball bearing fans that have been running for over 7 years straight less a few days (minus moving twice) with no issues. Sleeved bearing fans are OK, single bearing fans are better, double bearing fans are a bit better yet, and liquid bearing fans are the best by far.

I have two incubators with single bearing fans running no problem.... one for over a year now, and the other just fired up with two 120mm fans. Wire them to a 12v AC/DC converter with a rheostat to control them to the desired speed, or just use an old 6v cell phone charger to run them half speed. I have two 120mm fans running off a 6v cell phone charger and another using a $15 AC/DC converter (which I will probably purchase another).

Here is the converter I used..... it is a charger for batteries and can be found at many hobby stores.

Some really good fans for fairly cheap.....

Both the fans in my newest incubator are these same EverCool fans in an aluminum housing.
