Really quiet fan choices

[Devonjevon]

Well since changing to LED's my tank has no heating issues. But now since I use kalk for ATO my evaporation rate has gone down considerably. This has caused issues with maintaing calcium levels. I had about 1 to 1 1/2 gallon of evaporation per day prior to LED. Now I have about 1/2 a gallon. I don't want to invest in a calcium reactor.
I was thinking if I purchase a fan to blow over the water in my sump. I could increase evaporation.
And ideas on a fan?

Radio Shack has some in both 4" & 6" size that are very quiet and move lots of air, All you need is a adapter to plug them into the 120V source and they have those too. You may find them online cheaper but after shipping it may be easier to get them local.

I've got a USB powered fan that's dead quiet and it powers from an old smartphone plug I got it off amazon for 9.99

+1 on Radio Shack, just bought 4- 120mm fans($10 each). Go to walmart and they have a universal power supply for mosr electronics. It is also variable volts so you can run the fans at different speeds($18). Even at 12 volts its quiet and they push alot of air. I tempory wired them and put them ontop of my mesh screen top, it drop the temp by 2 degrees in no time.

Cool I might try the RadioShack fans first.

I generally use Yate Loon 120MM fans in my computers and reefs both. $3.60 each or $2.95 each if you buy 10 or more. YATE LOON 120mm Case Fan - D12SL-12 They are well regarded at silentpcreview.com. Just keep in mind that the last letter in the model name refers to the speed of the fan. The ones I linked are low. They provide a good amount of flow and are very quiet.
