Premade table top incubators fan is to strong, can it be fixed?

[SweetTooth]

Hi there folks hopefully someone with more knowledge can help me out here, I was given a cheap incubator, I've been running it with some dummy eggs for about 10 days, it holds temperature wonderfully, it's got alot of decent features and I think it would be a halfway decent incubator but.... the fan, it's beyond strong, the incubator is for 12 eggs this fan blows 3 times stronger than my 56 egger. I have read a few things some say you can just remove the fan and make it a still air incubator? then I've seen things saying to cover the face of the fan so air only comes from the sides?
So my question is would either of these options I found actually work? Or should I just replace the fan?
Thanks in advance for any advice given.

Here is the question.
Is the fan the original that came with the incubator??
Why do you assume a fast fan is a bad thing??
Just because fan is stronger than your 56 egg unit,,, maybe that unit is designed differently with heaters set up differently.
If you replace the fan,,, what will the new fan be like??
If you do cover the face,, it will decrease the airflow. Try it and see if you like the results.
I do not recommend turning it into a still air incubator.
There are ways to reduce the speed of current fan, by adjusting amount of voltage. That gets slightly complex, and if you are not into electronics, I suggest you avoid that option.
I can do it with things in my collection of items, But I am not able to tell you what to do with your incubator.
If you lived in the neighborhood, YEA, I would say. Bring it by. Lets see what I have.

It's definitely the original fan, it was given to me new in box. I'm thinking the fan it to strong its not a overly educated guess but due to how rapidly its loosing humidity I figured this might be the issue, the fan is strong enough I'd consider using it for a desk top fan lol, I essentially have to add water every 2 hours or it plummets, I was trying to run it for a lockdown incubator at around 65-70% RH, it's plummeting down into the 20s after about 3 hours and the temperature is maintaining perfectly. The incubator temp and RH has been calibrated to the same as a Bluetooth recording thermo/hydrometer that I have inside the incubator witch was bag calibrated just before being placed in the incubator.

I'm going to test covering the face and see how my RH% holds, if it's not any better looking into adjusting the voltage is a brilliant idea might be slightly out of my skill range atm but I love learning, as far as the still air option, I was considering it only because I've seen some things about them being good for hatching pheasants during the lockdown phase and I was thinking I could test out the theory if turning it into a still air was a viable option.

If you are loosing humidity,,,, is there a way to close off the vent where it is escaping???

It has a vent hole where the fan pulls in air, its about the size of a quarter, the only other vent hole it has is a tiny external water filling hole. I tried covering the water filling hole and it made no difference, I haven't tried covering the fan inlet vent as I was worried it would damage it, Is covering the fan vent a bit something that could work?

Covering a portion of the face of the fan didn't seem to help.

I believe so. This way you are not introducing ambient air. Just circulating the air inside. See how this affects the humidity percentages. Try closing half way, and then more or less. Not totally though.
When chicks start to hatch,, open that intake air hole so there is fresh air with oxygen for chicks to breathe

I have an adjustable fan on my diy incubator so i can raise or lower the amt of air it moves.I also added multiple vents so I could test how each vent affected the humidity and temperature .An intake behind the fan moves the most air and will cause a higher drop in humidity.The size of the air vent is determined by the output of the fan so you should be able to partially close it to increase the humidity.If you live in an area with a lot of of rainfall you may be able to use the dry hatch method
