  • OK it's not a chiller! By KerryF on 9/19/2015

    This little fan is a nice inexpensive option to a full blown chiller. It will not cool a huge heat load but if you need a few degrees drop over a few hours in the summer then it's a good option. It's a fan and all fans make some noise. No temp control so you'll need one. I use my Apex to control it and I can log the output to see it cycling on and off about every 30 minutes on a hot day. You'll have to figure out if it will handle your cooling requirements in place of a chiller...it did for me this summer.
  • cool fan By Bruce on 7/12/2015

    Nice little fan, small and out of the way. I like the mounting. Used this to replace a conventional clip on desk fan. Very quiet and cools better probably because it focuses the air flow across the top of the water. Have it controlled by my Apex so I like the little lights letting me know when it's on.
  • Great Fan By David on 5/27/2015

    Bought the fan to help out on those warmer days. Fan has a flat profile. Convenient mounting bracket. Produces a nice laminar flow. Very quiet. Attached to 120 gallon display tank, air flow is across the length direction. Connected to a controller that turns on upon reaching the upper temperature limit. The fan is does not drop the temperature in the tank immediately but does prevent the temperature from rising more. With the fan, I now longer see a plus 4 degree rise that I was getting without the fan. I am considering buying another unit and mounting the 2 fans across the width of the tank.
  • Small but noisy By Steven on 2/3/2015

    It sure makes a racket for such a little fan. Do not know if this normal. But its not like I have not asked. Moves the air pretty good. Should have bought the Air King fan. I feel like I wasted 80 bucks really.
  • Stay Cool By Glenn on 7/21/2014

    I was worried about having to buy a chiller. This product is great!
    It's running on my Apex and keeps my tank temp exactly at 79.5 degrees. My house is air conditioned, which helps.
  • Works as advertised By Brian on 3/5/2014

    Does a nice job. Brought my temps down consistently 2-3 def F, as any fan would. Nice, compact, looks good, and works well.
  • Underwhelmed By Tred on 2/23/2012

    I purchased one of these through a LFS and was excited to see how it would perform. I am sorry to report that I was very underwhelmed at the small amount of air that the fans move. I understand that they are supposed to be a quiet solution, but maybe a little more investment in better fans and less in LED lights that most of us in the hobby really wont appreciate. And it really doesn't need the 2 speed switch on there. My unit will be going on my BC29 controlled by my RKL and I will have no reason to be fiddling with a speed switch.

    All in all it is a well build unit, and it lives up to the claim, it is low-profile and quiet. Once summer is here in Oregon then I will know how it does with evaporation cooling.
  • Great By Conor on 1/11/2012

    It is awesome!! It works way better then those computer fans Jimmy rigged up. Worth every cent!!
