These LEDs can heat up quite a bit. I use CPU coolers, but with your large heat sink, you can make the air flowing above the fishtank, keeping temperature on the bottom side of heat sink low.

i intend to fix 2 spare cpu fan of mine on top. Hope the low rpm can bring down the heat. This setup is going to be in my office.

I've started using this today, with the 2 new cpu fan blowing on the heat sink ontop, The tank temperature still went up from 24C to 30C. With a big difference! The heat sink is not hot on top.

Anyone has heat issue inside the tank?

Most of the heat that the leds are radiating are going straight into the tank and getting trapped there because the top is sealed. I would suggest finding a way to raise it above the tank maybe an inch or two. You'll be surprised with the difference

Great stuff to read Tish, and yes, leds do become hot, especially the higher current ones...

In my tank i have the lamps inside mounted on the 12v fan heatsinks, when the fans run they are cool to the tough, while if the fans don't they get about 15 degrees C above ambient.

In your case, as mentioned above, i would try to have some space between your heatsink (i like it!) and the tank.

They might work well to supplement a window, otherwise you can move them closer to low-light requirement plants like a ceph, they would probably enjoy the little to no heat output.

Looking for any drosera capensis via seed, pm me!
I'm interested in any sundews.
