Low noise adaptors

[D1craig]

ive got 3 fans sitting in my PC 011 case on the side mount part as they only work on full speed with my hub so i just disconneted them. if i use a 3 way fan splitter and a low noise adaptor and just connect them to a molex adaptor what am i looking at? i would be happy for the 2200rpm fans that they are to run at anywhere from 1000rpm and lower. could i do this with a low noise adaptor at the end on the 3 way splitter into the molex or do i have to get 3 low noise splitters and connect them to each fan?

my case has 2x360mm rads with 1900rpm pwm be quiet fans that are perfect and work perfectly with my hub (the cheap phanteks one seems like the most reliable hub not at stupid prices out there). connecting the 3pin fans to that just makes them run max speed.

also i bought an 80mm noctua fan that maxes at 1800rpm. do you think this will make more noise than the bequiet (120mm) fans at 1000rpm? or should i connect this to the hub? i only ask this 1 because it will require a splitter aswell.

Forgive me as im not sure what you are asking with the three way splitter thing. Ok firstly what fans do you have and secondly does your MB have some kind of fan control?

When it comes down to quietness to me i get fans that have good static pressure and low DB, something like Arctic P12/14 is a great choice for cooling. Also fans with PWM is a must to let the MB control them based on temps so they dont just run full speed.

Are you using the sata power on the phanteks hub as well as the 4 pin PWM cable?

This causes the fans to run at full speed.

The 12V SATA power cable can not be used to power the PWM hub if connecting to these types of 4-pin connectors, due to the interference with the RPM regulation by voltage (resulting in the fans running on full RPM). The PWM hub will draw its power from the 4-pin connector, which is limited to a total device consuming 30W in total.

If you just use the 4 pin PWM cable on its own, you should have control over the fan speeds (the header on the mobo must be PWM capable).

3x 3pin EK Vardar. - not connected as when i did connect them they ran at full speed.
6x 4pin bequiet. - run perfectly regardless of whether the 3pin fans are plugged into the hub or not.

my motherboard is a z170 itx that only has 2 fans headers, sysfan and cpufan. sysfan is my watercooling pump, always at full speed and cpufan is what the hub is connected to.

im not sure if i have the sata power connected ill have to get back to you on that one. but with my 6 pwm bequiet fans plugged in right now they are controllable.

as of now i only have the 6 bequiet fans plugged into the hub which is perfect because there is 6 ports on the hub. so to connect the vardars and the new 80mm fan i would have to use a splitter cable.

Bear in mind that a low noise adapter's effect will be greater if you're adding more fans than one. Basically it's a resistor inline with the power supply so the more current is drawn, the more voltage it will drop. This lowers overall current. In fact you may find it can't run multiple fans at all - 3x fans means 3x the current, so 3x the voltage drop from the resistor. If you already have one, there's no harm in testing it.

well after lots of conflicting info all around the internet, some saying i could, some saying i couldnt, with many singular different reasons for each i decided to dig through my spares and found lots of cables from older fans and such. i also discovered i removed the EK fans from the case. i got the noctua installed as exhaust and installed one other fan i found that had a max speed of 1200rpm i stuck the resistor things on both of them and stuck them on an NZXT hub i also found that connected to molex so now i have my fans running (although not the extra 4 like i said earlier, just 2) nice and slow but pushing a fair amount of air.

oh i forgot to check if the SATA power is connected to the phanteks hub but after reading about it i think it must be.
