Aquaero question

[Raiden]

Hi ,

I got a question for you all aquaero owners , i own myself one and im going to use it at a modding , i will be using fractal 120 mm fans , im now using 2 fans controled by it, to cool a 240mm radiator, they are tacens 120 mm and they have 12 volts, my question is how many fans can the regular version of aquero control?



Only 4?

I need to control at least 8 , because i dont want to buy another controller for the fans


Ps: My aquaero is version 4.22

Thanks!

You only have 4 channels. Each channel can take up to 10W or 15W with the powerbooster while the total load of all channels combined should not exceed 30W respectively 45W.

[MrToad]

Does your Aquaero have powerbooster?

If it doesn't it's 30W combined load, with max 10W per channel, if it does is 45W combined load, with max 15W per channel except channel 1 which supports up to 25W (to connect a DDC pump for instance).

You've beaten me for 2 minutes! :p: (which means it's taken me at least 2 minutes to write my post... I'll never be SAAYA... )

No powerbooster , i may buy one maybe , so it can only go for 30 watts , then if fans consume 12volts each i can only use 3?

No powerbooster yet , it´s just the regular aquaero , so i guess i can only use up to 3 or 4 fans?

Volts, Watts and Amps are related to each other as described in Ohms law, but not the same thing.

A quick way to calculate the wattage of your fans is to multiply volts x amps. Your average fan is rated 0.3A @ 12V so it consumes 3.6W.

You can run two of those per channel with ample headroom. Three would be pushing it a bit, but the amp rating is the startup current, which means is not going to be consuming 0.3A every unit of time the fan is in operation, as once the fan starts spinning the current demand usually decreases.

For the rating of your particular fans check the label.

Thanks mate , Tacens fans indicate 0.27A/3.24 watts , so your rigth :up:


That´s all the info i needed to know , maybe with powerbooster i can conect 12 fans on it , going to check it with and Y cable for the fans

Be aware that the factoring rating might be (totally) wrong. We had an aquaero here some weeks ago where the PCB was burned. The customer said it can't be a damage due to overload but after he send us his fans we measured the load and ended up with almost twice the load that these fans were rated by the manufacturer.

Who was the manufacturer? Just sheer curiosity... It's usually the opposite.

I see , i will try with 8 Fractal fans and then see what happens , going to get a powerbooster:up:

Yeah i would like to know too:up:

Shoggy: have you thought of making powerbooster II with more heat dissipating area (like more fins to metallic heatspreader) + place to mount some fan - as in to make aquaero handle more power without any changes to schematics?
Also does aquaero feature some overcurrent protection?

[Shoggy]

That will not work at all. It is already a wonder that it works this way. The aquaero does not have any protection since it was also never made to handle loads like this. We started with 5W for each channel ;)

So if I understand it rite if I'm using GT-14 they are rated 0.049 amps each i could use 16 fans on one channel without buster?
0.049A*12V=0.588W
0.588W*16 = 9.408W

Starting current on AP-14's is .21A.

I'm 97.842% sure that this would even burn an aquaero with powerbooster :D

As Waterlogged mentioned that starting current is a problem and this is also only the rating from the manufacturer.

I was thinking to connect 9 fans on aquaero with power booster.
So ill need to use two channels.
