Has anybody done some DIY cooling setups with small blower fans? I was planning on using some small laptop style blower fans to put under the hood of my bio cube. i have my apex turning my skimmer off when the tank reaches 80.8 but am still battling temperature swings from 79 at night to 82 if i leave the skimmer on I exceed 82 during the day. I found one fan but killed it with a 7v plug didn't think it would be a big deal. Just wondering if anyone out there has better solutions.
