I have read responses on heat issues and I thought I had addressed my problem but it appears not.
Here is a little about my setup:
This is my second time using a computer cabinet that I have modified. It is 1.5 x 2.5 x 4 feet (=15 cubic feet).
I am running CFLs (2-65 watts, 4-42 watts, 2-23 watts).
I used to have those reflective thermo sheets up for reflective-ness but I thought that might be contributing to my heat problem so I took that down and painted the interior white.
I have a 4 inch fan that is supposed to move 230 cfm. It is attached to ~3 feet of ducting with on ~100 degree bend. I have it blowing through 2 sheets of carbon filters.
There is a considerable amount of wind being blown out so I know there is good airflow.
I did a test run overnight with all the lights on, fan running, and doors closed and when I got up it was 97 degrees!! The temperature in the house is a steady 75. Also, I have a little personal fan blowing on the lights. If I hold my hand between the light and thermometer, it feels fine.
What am I doing wrong?! Below are some pics to give you a better idea of setup:
Empty, painted cabinet. Holes on bottom are for intake![IMG_1215.JPG](/data/attachments/2320/2320229-925161ccc35262f19a70ad44d88701ad.jpg)
Ducting from light to fan to filter.![IMG_1226.JPG](/data/attachments/2320/2320228-1833dc4d99ebcdf098ca7abd557a8399.jpg)
Thin carbon filter air is passing thru.![IMG_1223.JPG](/data/attachments/2320/2320230-cb4dd4b267bb22b70d4dd4d337b0baf3.jpg)
Light setup and arrangement.![IMG_1228.JPG](/data/attachments/2320/2320231-1d53a55b03cff3bd2418e048bb1b0ac7.jpg)
Please help!
