I have some Gentle Typhoon fans I am thinking of using in my new build. Will I be able to control them via my motherboard? Can say three be connected to one header? They aren't PWM.

They should work just fine with voltage control.
And with that very low current draw you could connect five of them to most connectors which have 1A max current.

So is it the Rated current I look at? I saw 0.360A (Starting current) and wondered it that would exceed the max current with a few of them.

They work well on radiators so seems a shame not to use them. Sadly the cables aren't sleeved.

Now that's a nice mess with three different current values...
Current limit should mainly come from heating effect of current, so higher few seconds spike is likely OK.
Definitely at least three fans should be perfectly safe.

Yes is a bit strange. Came from a group. buy off another forum. Took 12 months before I them, flooding at the factory then some drama over who was processing the large order. They'd apparently stopped making the 1800rpm version so only took minimum order to make them again. I've got 6 of them so may as well use them.

While Gentle Typhoon 12B6AP draw only 0.123amps when running, but when starting up they can draw up to 0.530amps at startup. Anyone who doesn't believe me can look it up on Nidec-Servo websiste.

Yes just looking again and I have 6 fans. Two are the AP15 1850RPM version and four are the 2150RPM version that were the special order, probably account for the higher current draw.

Hmm may have to rethink how I use them then...

All fans draw 3-4 times as much power starting up as when running .. they also draw that same extreme load if bearing locks up of something stops the impeller. It's why most mobo fan header failures are when starting computer with multiple fans on single header.

Makes sense thanks, so are you saying only connect one to a header or alternatively connect them some other controller?

Brilliant fans are the GT’s. Haven’t found anything which comes close in terms of performance/noise.

7v molex works well if you want to lower the RPM and run them static.

I have realised I have a Phanteks fan hub. May try that, ideally want them to only ramp up if necessary. How do you find they compare with Noctua?

Compared to Noctua NF-F12, GT's are significantly better. Both quieter and push more air. Against the newer NF-A12, I reckon it'd be a dead heat up to bearing noise where the noctua would probably win as dual ball bearings definitely have a very slight whirr to them as Doyll said.

Luckily my hearing is aging so that may solve one issue :) I'm going to sleeve the nasty wires then control them via DC, should do the job nicely without any extra outlay. Need to put everything towards X570 etc. ! Once I a decent high end GPU I'll look at water cooling it. EK-MLC Phoenix on the CPU should be good enough.
