Hi all im looking a little info on replacing 3 fans on my led light .

The 3 fans thats installed in this light put out to much noice with not alot of air flow so im looking to replace them with fans that dont give of to much noise , can any one recommend 3 fans?

Fan size 80x80x25. 12v 0.25a if you can see from on of the images the fans have to have 2 pin connecter ?

here's some :- http://www.frozencpu...Fans-Page1.html


personally i use noctua fans.


i wouldn't worry about the width of 25 to much and any fan that won't have clearance problems can be used, like the 15's but will probably require you either buying shorter screws or modding/shortening the ones from the old fans.


also the 0.25A can be the same or less, the 3 current fans add up to 0.75A and the max amps of the power supply is 0.8A, so just as long as the fans you choose add up to 0.8A or less then you can use them.


if the fans are only rated in watts like this one :- http://www.frozencpu...356&id=mqrEQVWV

then to convert that to amps you just divide the watts by the voltage to get the amps.

eg 1.2W / 12V = 0.1A




forgot to mention you can use 3pin fans and either use an adaptor to convert the 3 pins to a 2 pin, like these :-  http://www.coolerguys.com/32pa.html

or just mod it yourself, the black wire goes to black and the red wire goes to red and the yellow fan wire is ignored because it is the fan speed sensor.
