Replacing Dead Fans On The Older Jbj 24g Nano Cube Dx

[steelhealr]

My fans quit after almost 3 years and I found my tank temperatures rapidly rising. Ahh...my dinosauric 24G.

Apparently the fans burnt out after awhile...ball bearings etc. Measuring the width, the old JBJ fans are 60mm or about 2 1/2 inches. Found neat replacements at a huge computer center near me. The fans appear more powerful but are thicker..

What you need

• wire cutters
• small Philips head screwdriver
• soldering iron
• weatherproof wire connectors
• 60mm fans, commonly found at large computer centers in the peripherals department
• the nerve to keep on doing your own stuff

Method

1. Turn off the power. Unplug all electricity
2. Lift the hood and cover the aquarium so you don't lose anything into the tank
   
   
   
   
   
3. Remove the four screws holding the splash shield
4. Pull the PC lighting tubes and unscrew the support brackets and retaining screws from the reflector shield
   
   
   
   
   
5. Remove the four screws holding the fan and pry off the JBJ fan
   
   
   
   
   
   
   
   
   
6. Cut the red and black wire and toss the fan
   
7. Splice the new fan wires onto the JBJ wires, solder, and cover with small weatherproof wire connectors
   
   
   
   
   
8. Screw the fans back on, tuck the wires behind the reflector; then reattach everything in reverse
   
   
   

Notes: The fans I purchased fit the grill on the JBJ hood perfectly but they were deeper/thicker.

I had to modify the splash shield a little where it covers over the fans. Also, the screws were too short but I was able to use 1 1/2" #6 metal screws without difficulty.

Hope this helped.

Hard to believe your tank is that old SH, it's held up well over the years.

are you still using the cracked one?

Yes..same tank...it never extended so I must assume that it was partial thickness or not deep enough to compromise the integrity of the wall. SH

i don't think i could live with it, any time there was a noise in the night i'd be running downstairs to check the tank
