![]() I just bought this RSM 250 from Dempsey a fellow forum member, got a good deal and he has done the Steve's Led retrofit. The tank is in beautiful shape, BUT! the 2 little side by side fans at the back of the hood for cooling and keeping the hood from moisture building up are really quite loud. Has anyone found any good quality ball bearing fans that are a good replacements for these.

![]() Not much help on quality but if you do a search for 12v dc cooling fan 6020S lots come up on eBay. Just pick a quiet fan that moves enough air. Can also order red sea replacements.

![]() Have you tried reducing the voltage? I use to have the same fans way back and ran them at 6v instead of 12. If you have two fans on a 12v source just wire the fans in series to split the voltage.

![]() I picked up a RSM 130d recently that needed a fan replacement as well, I found some 50mm 12V fans at RP Electronics that I'm going to try out. They are 10mm as opposed to the stock 15mm depth, but from what I read if you sit them back from the fan grille you can also cut down on the noise the grille can make. (The fans were in the $7-10 range, pretty average. And I can see there's a 0.10 amp/4000RPM and 0.16 amp/5500RPM version)
I don't know if the RSM 250 has the same fans or not. There were all sorts of sizes though. Last edited by MKLKT; 04-09-2015 at 02:56 PM. |

![]() I called Red Sea and they only carry the same replacements and have no quieter ones available. Not going there thanks!

![]() Before going out to purchase replacement fans. This is what I did to my RSM130 fans which cut down on the noise
1. Remove the fans from the hood 2. Carefully removed the sticker and and rubber cover from the the fan 3. Paced a drop of 3 in 1 oil at the bearing/axle. 4. Worked in the oil by manually spinning the fan back and forth. 5. Replace the rubber cover, sticker and reinstall the fan into the hood. Red Sea has instructions on how to remove the fan from the hood and there are a few videos on Youtube which will guide you through the oil. I did this six months ago and the fans are still relatively quiet. These fans are small and move a fair bit of air, there will always a audible noise produced from them. If you can't stand the noise, I believe Steve's LED carries a different type of fan, from old Sony Trinitron TV's. They are a drum style fan and should be a lot quieter. Good luck! |

![]() My RSM has loud fans when it starts up on the timer. After 5 minutes it goes quiet. Have you let it run for a bit?
