Can I daisy chain three gentle typhoons to one motherboard header?

3t3P · 20 Oct 2010 at 10:07

I ask for my build over in the project section.

As these fans (1450's) have exceptionally low current draw, I thought I could easily daisy chain them with the cable I have and control them off the motherboard using speedfan until I get an aquaero system in over the next few weeks.

Cheers

I wouldnt personally chance it to be honest, go with 2 for now and wait till you get the aquareo system?

Really wouldn't. Might get away with it, but you really don't want to burn out the motherboard header.

Ok well they are quiet at full power anyway, i'll just use a molex adapter and run em full whack on the rad for the time being, got shrouds and no resistive grill to push through so should be quiet for it

you need to check your motherboard specs and see the amps of the fan header then look at the amps of the fans which i believe are 0.049amp or about 0.6 watts per fan at 12 volts

most mobo fan headers are >1 amp which equates to about 12 watts technically/theoretically you could run about 15 of these fans on a 1 amp header altho it's not something i would risk, better safer option would be to buy a Lamptron fan controller which have around 30 watts per channel or about 2.5 amp i've seen info elsewhere where the lamptron managed above 40 watts before failing.

it's upto you on a spec basis yes you could link upto 15 on the header but it's a toss up between blowing an exspensive motherboard or blowing a channel on a £25 fan controller, because if the fan header goes it could take out other parts of the motherbaord with it.

hope this helps i did a great detail of research on it last night for myself

The akasa viper pwm fan is used on mobo headers with cpu coolers. The draw about 4 watts. Considering three gentle typhoons use less than that it should be fine.

While it should work... I wouldn't chance it - I've seen on more than one occasion motherboard failure that seems to be due to daisy chaning fans off a single fan header.

I heard somewhere that even though GTs use a low current in operation they do have a higher starting current which may cause a problem.
