** PHANTEKS ENTHOO PRIMO - THE ULTIMATE WATERCOOLING CHASSIS **

Mine could do with a tidy behind the tray tbh, and its only gonna get worse unless i adress it soon. Installed a second 780 today, currently one card is powered by 2x standard corsair 8 pin pcie cables. The other has custom braided extensions on the 6 and 8 pin cables. Need to get matching extensions for the new card.

I have come to the conclusion that my Phanteks fan hub just isnt working in PWM mode. I have tried all sorts of combinations. I have plugged in a Phanteks PWM fan to CPU1 or 2 and have controlled its RPM from 0-100%. However with the fan hub connected to either I cannot control the speed of any of the fans.

Can someone please confirm that it is mandatory to plug in the MOLEX for the fan hub if there are more than 6 fans connected to it (because that is not what it suggests on the sticker on it) and that they have a MOLEX connected to their PSU and PWM functions still work!

Plugging a PWM fan into a 4-pin hub and having speed control on the fan does not mean that PWM is working. It only means you have speed control of some kind .. probably variable voltage .. maybe PWM controlled power going to the fan. But that is not a PWM signal going to the PWM fan on pin 4.

I have yet to see a Phanteks PWM controlled 3-pin fan hub that did not work when used with a motherboard that was sending it a PWM signal on pin 4.

The Phanteks fan hub will work as a fan splitter drawing power from motherboard. Just do not try and run more then a total of 1amp / 12watts of fans. I wouldn't run more then 10 watts of load.

My Phanteks hub works great. I have PWM signal going to it and to other fans not on the hub too. The hub's molex is plugged to PSU and the fans on the hub are controlled with no problems.

Using the molex power to hub and the PWM signal from motherboard on pin 4 to hub regulates the speed of fans plugged into hub. But if you do not have a PWM signal going to hub and plug in the molex the fans on hub will run full speed.
 
Regarding the hub, from an asus mobo owners perspective. On my board in sig, only the cpu fan and cpu opt fan are true PWM headers, (opt fan mirrors cpu fan). All other headers on the board are 4 pin, but theyre not PWM enabled. Not sure how other board manufacturers have theirs setup.

Nice one mate, when are the water blocks going on? :D

Theyre not, im too skint now lol.:D Tbh mate im pretty impressed with the temps so far. 63 and 53c respectively. Not too bad for non ref heat dumpers in a board with a one slot gap. My 670's ran at 70 and 56c in this board in my old shinobi xl case. It speaks volumes for how good the primo is even on air cooling. Ill fire up a few pics later, though it does look a bit odd due to the ugly corsair cables powering the top card.:)

Nice temps mate, Primo is certainly very good. As long as we both go WC before Matt does. ;)
 
Yep, airflow into the case is very good, cpu wouldnt even benefit that much from watercooling either under certain uses. Being a haswell, it will run very hot in stress testing wether on air or liquid. Delidding it would be more beneficial but risky.
 
Phanteks fan hub and Swiftech 8-way PWM hub are very different beasts.
They are both fan hubs, use PWM signal to control and 12v power from PSU, but that's where the similarity ends.
  • Phanteks PWM hub controls 3-pin variable voltage fan speed by using the PWM signal to change the voltage going to the fans.
  • Swiftech PWM splitter controls PWM fan speed by splitting the PWM signal from motherboard and sending it to the PWM fans along with a constant 12 power lead.

delpy8, you have email

Cheers doyll, So could my Phanteks fan controller be faulty also as it did not reduce the speed of my fans even with it connected to both the optional CPU fan and main cpu fan header all fans spun at 100%

I have got a spare one lying around in the house let me have a look and I will send you it ;)

Many thanks..more than happy to cover your costs :)

So basically with the Swiftech you have to have PWM fans whereas with the Phanteks you can just have 3-pin fans and they will have 'PWM' control via the hub.

Not a problem trust me your address :)
I've emailed phanteks as I'm not sure why I cannot get the fans to reduce in speed when connected to the chassis hub

I have sent you a trust message :)
This is what Phanteks sent me in response to my question:

If when you plug in the molex connector your fans jump to 100% that means the signal from the motherboard is not a true PWM signal and instead a voltage controlled signal. For example if your motherboard it putting out 8V (66% of 12V) once you plug the molex connector, the voltage will automatically jump to 12V (100%). You will need to change the signal that your motherboard is using to control the fans to "PWM mode" if possible in the BIOS.

I did adjust my bios to silent and even tried this in manual settings and still had 100% NOT SURE what to do then

That's exactly what I emailed them back. According to MSI (who I have emailed and waiting for a reply) the header is a PWM header and therefore is supplying a PWM signal to the hub.

I don't even have an option in the MSI BIOs to activate/deactivate PWM function!
 
"PWM Header" can be two very different kinds of PWM control .. and that is assuming that it a "PWM header".
  • PWMwiringadapter_zps6f61ae54.jpg
  • Pins 1 & 2 are ground and 12v power, pin 3 is RPM and Pin 4 is PWM signal
  • Pins 1 & 2 are ground and pulsed power (PWM Powered), pin 3 is RPM and pin 4 is nothing.

If it is the first kind than the Phanteks fan hub will work.
If it is the second kind the Phanteks fan hub will not work.

Here is a simple way to make a PWM signal controlled adapter with 12v power from PSU
If a PWM fan can be controlled by motherboard with this setup then you have PWM signal control from motherboard.
If a PWM fan only runs full speed then you do not have PWM signal control from motherboard.

If you look at the photo I posted earlier from the MSI manual it clearly shows that the CPU headers are the 'first kind.' Yet the Phanteks hub spins the fans at 100%??
 
I have learned the hard way not to believe what the manuals say. They are often wrong.

@Type R,
Have you tested to see how a PWM fan performs wiith an external power source to it? Because if you have not verified that you have a PWM signal on pin-4 and 12v constant power on pin-2 all bets are off. In other words we do not know how motherboard is controlling PWM fan and therefore cannot know if it's motherboard or Phanteks hub that is the problem. I have not yet seen a Phanteks PWM hub that was defective. Not saying that there may not be some, Just saying every problem I've seen so far was not caused by the PWM fan hub. ;)

All I can say is test the header to be sure how it is working. My Gigabyte works fine.

Delpy8,
Have you verified your motherboard is sending a PWM control signal on pin-4 and constant 12volt on pin-2? I'll take a look at your manual and see if I can find anything.
