cooling fans

I have a Fluval Evo 13.5g and the eshopps nano skimmer pump is producing too much heat for a stable temp even when my heater is turned off. I need suggestions for a cooling fan or system, ideally that would fit in the empty chamber of my filtration compartment on the side (9cm x 7cm x 1ft).

Has any one ever mounted a fan to a radion rms track mount? I want to get fans and mount them to it and have it blow down on the water. Yes i know it more effective going across but don’t really want that. But has anyone done anything? If so pictures plz

JBJ Arctica 1/3 HP Chiller. Used for a little over 3 years. Works great. Cools my 150 in no time. Pick up only in San Jose, CA. $550

Rising temps outside has made my apartment and my tank temps rise!! I was struggling to get the airflow needed to cool my tank. Biofish has designed a 3d printed model and it is a mount for a small cabinet fan that allows airflow to escape from the tank getting rid of humidity and raising tank...

I'm searching for a cooling fan that can be used/controlled through the Hydros Control 4 Drive Port, but haven't been able to find any online. Can anyone recommend any?

My used RSM130 that I have recently purchased is running hot. It has the hood with stock T5 lighting. It does not have the water cooling fan in the back, but a vent cover in its place. I have temporarily unplugged the heater to make sure it’s not stuck on. Most of the products for this tank...

Used for a few days during period my A/C was broken. Essentially brand new. $20 shipped.

Hi there, This is my first post on R2R and I probably should have started with a build thread (almost ready). I will try to do it soon. My question to the community is if anyone has implemented a "hybrid" (evaporation + chiller) cooling strategy. I am in the Southern hemisphere (Buenos Aires)...

Like new. Purchased from another member who used it for one summer. After purchase, I decided to install air conditioning in my basement. Comes with Ranco controller. No longer need this. $475 shipped.

I am looking for silent cooling fans to add either to my display or sump. I'm running a rimless tank so my criteria is sleek and quiet. Nothing bulky. I also run a Profilux 4 so I have checked out the GHL fans but they are pricey. Let me know what you are running on your tanks.
