CoolWorks Ice Probe with Power Supply Information

Product Manuals & Documentation

  • Efficient: converts electricity directly into cooling power
  • Reliable: the fan is the only moving part
  • Easy to Install: one hole, one nut
  • Safe low voltage operation
  • Environmentally Friendly: no gasses or chemicals
  • 1-year manufacturer`s warranty from purchase date

The IceProbe is the ideal cooling solution for small aquariums. This quiet, reliable, and efficient chiller uses advanced thermoelectric technology to directly covert electricity into cooling power.

With its threaded probe, nylon nut, and silicon washer, the IceProbe, can be easily bulkheaded through a 1.25" hole into siphon overflows, prefilters, sumps, or even directly into acrylic aquariums.

A single IceProbe can cool 10 gallons of water 6-8F below ambient air temperature in a standard aquarium. Multiple IceProbes can be used in a single aquarium to achieve higher temperature differentials.

The IceProbe provides continuous chilling power. A separate temperature controller must be used to turn the the device on or off at predetermined temperatures.

Weighing in at only 2 pounds, the IceProbe® is powered by a separate 12 volt D.C. power supply and draws less than 50 watts.



  • 50 Watts of cooling power
  • Compact size
  • Easy bulkhead installation
  • Quiet, efficient & reliable
  • Optional temperature controller
  • 120V

Comments: I have 4 CoolWorks ice probes. Axolots need cold water, below 20oC and are housed in two different 10 gallon tanks. The other two are in two 20 gallon tanks set up for goldfish, which also like cold water. We set up a stainless steel triangle that sits in the corner. This works fairly well, but we needed to secure the piece with some duct tape.

Comments: i have a 10 gallon that i keep a axolotl in, and get the ac on 75 it was a little hard keeping the water cool because they shouldnt get over 72, i ordered this and drilled a hole in the lid were it goes in the water were the water is flowing out the filter, my water temp stays 68-70 now, im very happy, havnt had any problems. i think its made pretty solid its seems like just one big piece with a fan on it. when the lid is open to do whatever. the water still on the probe will turn to ice, thats pretty cool. and lets you know that it really is working

Comments: I purchased this to resolve issues with heating with Metal Halides on a small tank, however, I received it over a month ago and have yet to be able to use it because it's not designed to sit or attach to anything other than a bulkhead. The cooler if very effective, it just can't be connected without doing some sort of mod if you don't have a bulkhead ready. Also, If you plan on doing a mod to a hang on filter, pay attention to the placement so that the probe doesn't interfere with the filter cartridges. I was very annoyed to find out the probe would only fit into my filter where the cartridge went - either no more HOB filter or don't install it.

Comments: I put 2 of these on my 20 gallon in the sump and I dont see any difference in temperature, so I put two clip on fans blowing on them to make sure they're getting good airflow and still no change, dissapointing. I guess I will have to buy a regular chiller.

Comments: CoolWorks Ice Probe was bought out by Nova Tec, but design is exactly the same. Long story short, buy instead something like Aqua Euro USA Nano CL-85 Chiller ($165, very quiet). To be fair, Nova Tec says mount Ice Probe directly on a filter. For my compare, I filled two one-gallon glass jars with salt water (store-bought jars, they are very thin). Put some paper insulation on the back half of each jar. I constructed a "cooling tower" out of .25" thick acrylic: 10"x5"x5". Mounted 3 Ice Probes and a very small submersible pump all inside the tower (they are working in parallel). Two 3/8" I.D. siphon tubes complete the circuit. This setup cooled, at best, about 6 degrees F. Way below advertising! Replaced "cooling tower" with the CL-85 (it uses two .5" I.D. connections). I put the same submersible pump in a small external cup of its own (note, one siphon tube gets replaced by the two .5" I.D. tubes). This setup took about 24 hours to lower temperature by 10 degree F. CL-85 holds the temp you set. This was a fair comparison. Both times the same submersible pump and hot-air exhaust from the nearby chillers tended to reduce the cooling capacity. By the way, each Ice-Probe has a clunky in-series power supply which adds to the clutter. CL-85 is new so I do not have any estimates of how long before breakdown.
