That is part of what is so wrong about crap like the Corsair h100i GTX thing:devil:.

Thats not right. The sata connector provides power for the hub on the Predator radiator, the hub then provides power to the fans and pump and also PWM signal that controls the fans AND pump speed combined. With the unit as supplied by EK and fitted in accordance with installation instructions you will have PWM control over the fans and pump combined ... when you turn the fan speed up the pump speed goes up with it. This is how it is designed to work. If you want to control the pump speed and fan speed independently then you need to unplug the fans from the Predator hub and plug them into a mobo header, then unplug the pump from its header on the Predator hub and plug it back into the Predator hub on the hubs 'Fan 1' header as this is the header the hub uses for the PWM signal communication (none of the other hub headers will communicate a PWM signal). The pump will then communicate it's PWM signal via the hub and with the hub plugged into a PWM mobo fan header you can monitor and control the pump speed. So for independent control, for example, this is how mine works ... Predator hub plugged into PSU sata power and mobo CPU-FAN header (as shown in the installation manual) // fans unplugged from hub, joined with splitter cable and plugged into CHA-FAN-1 mobo header // pump plugged into FAN_1 on the Predator hub .... this lets me control fan speed via PWM control of CHA-FAN-1 mobo header and full pump speed PWM control from CPU-FAN mobo header. So the Predator hub is supplying power and PWM control to the pump and the fans are running off just the mobo. This is the way EK themselves advised me to do it and it works beautifully smile.gif I can now change fan speed without affecting pump speed and vice versa smile.gif

Was about to correct Captn goobly gobbley myself. Lol. 🐸 Must have been misinformation saturday.

Also, the Corsair units have separate fan and pump speed options so not sure what Captain Hook was talking about.

Thanks for the detailed info thegoatman, I will try to do this next time I open my case. biggrin.gif

Very interesting. I will reread the EKWB manual. I won't have the EKWB 240 for a week or so. So, you are still are running the fans and the pump independently of each other just off of the two different and independent mobo headers. You are then running the pump at full speed, but can change the pump speed if ya want to, right, (?), while only varying the fans speeds, right? If this so, this is good and that then accomplishes what I would like the system to do for the reasons I rambled through before. Either way, this is good. Having the fans and the pump running off of the same PWM header as of now and before has blown the pumps several times on my guy. Ah, the logic stands if it is just the way EKWB has implemented the connectors. A minor variance but the objectivity remains the same. We will study this some more.
Thank you,
sincerely,

Yes, the Corsair has independent control cept through their buggy software, which only works sometimes, so as I quit using their software, (a presented feature by Corsair but it is really a detriment), because the one power connector to the pump from the fan header overloads the fan header and confuses the signal and feeds back the signal to the pump and connects to the pump first and only and then splits the power to the pump and fans at and through the pump causing all kinds of problems like overlapping spikes because the pump and fans have different power and current requirements and draws. This the problems we here and others have and are having. This is what EKWB has apparently resolved. A messy problem that shouldn't exist in the first place. Ahhh, marketing mixed with bad engineering is never good. Hmmmmm.

There is a distinct difference between arguing and discussing a subject matter. We here think that this is a positive learning discussion going on here going with us all. A big difference between forums and social media. This is good as we all learn sumprin.

There is no overloading of the fan header for Ek. The only mobo header you use is a 2 pin PWM signal cable. The hub on the Predator supplies power to both fans and pump which then they all work in tandem off that pwm signal. The pump is only a 6w pwm 3.1 ddc it does not require much to run but does require that sata for power, reason being 1 sata can power the fans and pump. To work independently you can :

*Move the fans from the hub to your mobo headers. Leave pump on hub to get a direct pump rpm signal.

*Get a controller that can support more then 6w per channel and disregard the hub all together.

The hub to me just looks like a single channel pwm controller that splits 4 ways, unless the pump requires a special spot on one of those 4 pins that supplies more juice then the other 3. Would of been nice to see 5 4pins for push/pull setups.

I just woke up and am still half asleep, or is that half awake or . . . rolleyes.gif More research is necessary.

Basic research is what I am doing when I don't know what I am doing.

I will say i never used Corsairs new AIOs that supply power to the fans through the waterblock's hub, but I've never had a AIO fail on me for years. It all depends how you run them as most people don't get it and run AIOs 100% pump speed 24/7.

Just and FYI be careful with the SATA port, I broke a tab when trying to move it in the Casey. I will say it's the cheapest part of the kit.i think EK should offer two versions, on in pull and one in push. It's a pain to switch it to push and can't replicate their outstanding cable management .
