UPDATE: Go down about 10 or 11 posts and look at hte discussion from there on. That's where the Silencer 80mm fan was first posted. SOmeone bought it and it's quieter than anyone could probably have imagined.

After looking at another thread whihc wanted a quieter cooling fan, I reembered back in my days of car audio that they created a fan to suit the bill. I found an example of hte style of fan here:

I am currently trying to find dB levels on these fans as compared to others and will post links when I find them.

Found a bunch of them made by Stinger. I still am having trouble finding dB levels though

Hi,

I'm new to this group, and relatively new to high tech planted tanks. Anyway, when I bought my light strip 6 months ago the fan was quite annoying and I pulled it out quickly. My intention was to replace it with a quite one, but I haven't gotten around to it. I'm sure I'm buring through my bulbs quicker than I should.

Anyway, my reason for posting, you might want to consider some PC fans. When I did a search 5 months ago on Google I was able to find quite a bit of information regarding noise levels and reviews of fans. There is quite a bit of interest in noise levels for PC fans and it is increasing as people are building PC to use with home theather setups. You don't want a noisy fan while you are watching some great drama sceen with your wife.

I'm interested in what you find as it is getting warmer in my house and I'll need to cool off the top of the tank soon or it will get too warm.

Later,
Tony

P.S. Please excuse an spelling or other mistakes. This was a quick write.

Get one with a rheostat then you can find a happy medium between max cooling and max noise.

if youre looking for quiet fans why not consider computer case fans? there are some computer modding websites out there that list the db levels of the fans that theyre selling and the amount of air movement they make. one of the websites is sidewindercomputers and plycon. im not exactly sure if the sizes are what youre looking for but just to give you an idea an 120mm fan is a little bigger than a audio cd. hope this helps.

You can get really good PC fans in both DC and AC. I would caution you to double check the noise levels. there is good information on the net for most fan manufacturers.

One note is that larger fans push a much larger amount of air. A 120mm fan can replace 4 80mm fans, but you have to be carefula bout the noise.

I am curently running a 120mm set up to a dimmer switch. By lowering the speed 1/3, the fan is 60% quieter. I use it to remove the heat from 330w of light in a semi open hood. When blowing onto the water it can lower the water temp by 10F compared to without it.

How would you hook up those PC fans to a normal outlet? Would you hook them up to the ballast? How did you hook up a dimmer on the fans? The fans there listed on these two web sites<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR>one of the websites is sidewindercomputers and plycon <HR></BLOCKQUOTE> came with a three pin hole adapter? How does this hook up to the ballast? I have the AHsupply ballasts. I am not very electrical smart. And would two 120mm fans be enough to cool down PC on a 100gallon tank? Thanks

AH Supply didn't Supply a cooling fan with my 2 sets of 2x55W lights. Do I need a cooling fan? If so, can I attach it somehow to the ballasts for power? I have no idea how this would work and I'm fresh out of outlets. The lights will be mounted 5" above my 100 gallon acrylic tank.

6 outlets available - 2 heaters, 2 filters, 2 ballasts. No more outlets...
Please help.

Its not possible to connect a PC fan to a normal outlet. PC fans do not run at 120V like normal outlet.

Im an English teacher in school, not in this forum. Hence, I spell, you spell, we all spell bad.
