Hey guys,

I am having a problem getting the temp on one end of my incubator up. I am using a cooler design. From overhead it's like this:

______________________________
|_____ _____ _____ _____ _____ |
||TUB| |TUB| |TUB| |TUB| |TUB| |
||*0*| |*0*| |*0*| |*0*| |*0*| |
||*1*| |*2*| |*3*| |*4*| |*5*| |
|_____ _____ _____ _____ _____ |
|____________________________|

There's 11 in FW on the bottom. A layer of water bottles over that. Then the tubs on a egg crate shelf over those.

Without a fan, the temps are higher toward Tub 5 and cooler toward Tub 1. So if Tub 3 is 89, Tub 5 is 92 and Tub 1 is 86.

So with a single CPU fan placed on the end where Tub 5 is pointing toward Tub 1, Tub 2-5 are all either 89 or 90 but Tub 1 is still 86.

Tub 1 is currently empty but I have another clutch dropping in about 9 days and need to get it up without making all the other get too high.

So are there any suggestions? A better place for the fan? A 2nd fan maybe?

Thanks.
