Blue LED fan that can also act as night light

[shaohui75]

Saw in the market selling this really cool DC fan. Probably can cool down the tank and at the same time act as a night light. Anybody here tried it before?

problem is fan usually blows across the surface not onto the surface whereas lights need to be directed into the water not across...

but i think it's a pretty good idea..

This fan cost around $15. Dimension of fan is 8cm x 8cm x 2.5cm, Speed at 2500RPM, air flow of 32.5CFM. It is actually meant for cooling down CPU.

How many of them do you guys think is needed for a 4feet tank?

I think 2 wud do the trick. Currently using those 6 in a row type. Too easily konked out... So far 2 fans out of commission liao...

Which kind of fan is better DC or AC? Are AC fan very nosy?
