Lowering temperature?

[TPG]

Hey guys. So my Vivarium temperature ranges from 80 degrees F. to 90 degrees F. I need it to drop in temperature to about 74 degrees to 82 degrees F. Does anyone know any metods to use or any tips on how I could achieve these temperatures? Maybe special fans or something?
Thanks

computer fan blowing cooler ambient air into the tank

Cooler lights.

Raise lights off the top of tank alittle and have fan blowing between lights and top of tank.

Just a few thoughts.

What's the room temperature? Sometimes it's probably less trouble to cool the room than the tank.

You should simply install air conditioning in that room and regulate it to whatever temp you desire the air to be! Good luck.

Now that I think of it, the room with the tank is much warmer than the rest of the house. With the window open, cieling fan on, two small computer fans in the tank and the lights OFF, the tank is still at 90 degrees. For some reason the room just stays quite warm. I'll try to cool the room.

Luckily there are no inhabitants in this tank yet. The plants appear to be holding up just fine. They've been established in the tank for a good 3-4 weeks now.

Thanks for the help guys

So I built a canopy and raised the lights off the tank about seven to eight inches and placed a six inch fan between the lights and the tank as recomended to me. I also placed a couple other fans in the room which make the room temperature quite cool. Even with this done, turning the lights off, and supplying no other heat source to the tank, the temperature in the tank itself is still at about 90 degrees.

I'm now wondering if the problem is strictly a ventilation issue. The top is coverd with glass, and I covered the front vent (I'm using the longest Exo Terra tank) with electrical tape. There are two small computer fans inside the tank to circulate the air, but the is no air exchange unless I open the doors. I was thinking about making a small opening in the top and placing another computer fan over the opening facing downward to provide fresh cooler air.

Does this sound like a good idea to you guys? And will this dramadically drop the humidity?

Thanks

You know what I think it is? Your thermometer. Is is a puck type meter or a digital one? If it's digital, change the batteries, if it's a puck type, scrape the piece of crap off the glass and get a digital one, lol...

I think that if the air in the room is 90 degrees, moving the air around isn't going to do too much to cool it- what does the thermometer say now that you have the fans in place?

Froggsong's point is a good one, too- it could well be the thermometer.

Well the room is much cooler now then before. A fan is located at the window bringing in cool air, and another fan (oscilating tower) is keeping it cooler as well.

I thought it could be the thermometer too. It's a digital one. The Exo Terra combo meter (thermometer and hydrometer). It's brand new, but I'll replace the battery anyway.

I'll post results after I change it.

Ok so the battery in the meter was fine. So any more ideas guys?
