Hey everyone!
I just installed a 2080 ti hybrid kit on my EVGA 2080 ti black edition. It's working great. I mounted the radiator in push/pull configuration with an existing case fan. This case fan is powered and speed-controlled by the motherboard. The hybrid kit of course powers the other fan on the radiator, and the GPU controls the fan curve of that fan (though precision x).
I'd like to control both fans on the radiator with precision x. My question is, does the hybrid kit provide enough power to run 2 fans, if i were to install a fan cable splitter?
GPU model: 11G-P4-2281-KR
Hybrid kit model: 400-HY-1384-B1

Hey! TLDR: probably, yes :) Long answer: it's all about power consumption :) Power (in watt) = Tension (in volts) x current intensity (in amperes) 4 pins headers typically run on a defined 12V. On modern graphic cards 4 pin headers can usually provide up to 24W of power = 2 amps. This is more than 4 pin headers on motherboards which usually provide only up to 12W of power = 1 amp. A typical 120mm fan runs at 12V around 0.5A (depending on the fan model). Since you're using a 120mm case fan as additional one, it should use less amps than regular 120mm fans because it's less powerful than 120mm fans designed to cool CPUs. Since the VRM fan of the hybrid kit is smaller than a 120mm fan (i'd say 100mm or 80mm), it'll draw less power than a 120mm, so less than 0.5A. So if you use 2 fans that typically use less than 0.5A on a 1A capable 4 pin header it should work with no problem. If the 4 pin header on the 2080ti is 2A capable you could even put 4 fans there ;) But i also dont think that adding a 2nd fan on the hybrid kit radiator would change much to the temperature results you will be getting since the difference between 1 good 120 fan and 2 fans to push the air through a radiator is not really big. You should try to connect the 2nd fan to your motherboard first and see how much degrees you win by doing that. It probably wont be much, so probably not worth it ;) If it was EVGA would have added a 2nd fan already on the kit

Actually I've only ever run it with 2 fans. The problem is, they're not controlled by the same things, so they spin at different speeds, so I'm not getting the best cooling just yet. Unfortunately i don't have a setup where i can test it with just the 1 fan at the moment. Sorry!

Exactly. Best to use the same fans in P/P so their speeds are sync'd.

That's what I'm going for! So then the EVGA hybrid kit can provide enough power for 2 fans in push/pull? I just wanted to be sure before i put in the splitter and put too much power draw on it.

I use this and have the Push/Pull set to Intake into the Case to bring in cooler air.
 Silverstone Tek 120mm Ultra Fine Fan Filter with Magnet Cooling FF123B (Black)
So you have 2 fans connected to and powered by the 4-pin fan wire that comes out of the hybrid module?
Yes in Testing but whet with a Fan Controller in the end. They Y-Adaptor needs to be the correct one. It needs to have 4 Wires on the Single Side and on the Y Side One needs 4 Wires and the other Only 3 Wires. Do no use a Y-Adaptor that has 4 Wires on all 3 Ends. You can even use a 3 Wire Y-Adaptor and this would have 3 on the Single end and on the Y End 3 Wires on one and 2 Wires on the other. Do no use a Y-Adaptor that has 3 Wires on all 3 Ends. Fans used  $9.74 Fan, 120x25mm, 108CFM Part No. FAN-12025HBK Current: 0.28A Amps to Watts Calculator

Hey there Atticus,
Echoing the above posts, believe the max amp limit to be 1A.
I run two Noctua NF-F12 2000rpm fans via a Noctua Y-splitter off the card itself.
The Noctua fans on the website (Noctua's great in that all their fans list the max amperage draw on their website) state a max amp draw of 0.1A (tiny) and I have not run into any issues.
Fans sync together and are controllable via EVGA PX1 and Afterburner.
A 2080 TI FTW3 where I installed the Hybrid kit separately.
Just wanted to let you know :)
Thank you & kind regards!

I can't think of any load from any properly functioning fan that would present a problem in a modern computer. If your power supply isn't on fire before you add the 2nd fan you'll be fine given the minute new load you are placing on your power supply. A single fan will not tip your PC into electrical overload.
I may have missed it in earlier responses but it sounds like you want to control cooling and electrical usage and generally have a smarter computer.
One person asked for you to submit new temps compared to old and you said you didn't have a way to do it. The problem with that is that you'd also have no way to know why you need more fans or, if you do, what kind of fans and how to control them. And that's what a controller can help you with
A fan controller will solve almost every issue talked about in the message thread. No splitters required and the power all comes to the fans thru the controller. You can still split but the first six fan have their own connection on the controller. The controller plugs directly to a drive power connector just like a hard drive. No big deal just plug and play. One stop shopping and you gain the tools to address requests for temperature changes for example. Temperatures and fan speeds are on your screen when you choose to see it. I use a Corsair Commander Pro and ICUE software and after a simple learning curve watching YouTube fan control has become very simple. ICUE also monitors my HXi PSU and Keyboards and allows me to manipulate them from a single program along with the fans.
Each fan can be individually programs to make it do what suits your needs. I think it take care of all the issues you are dealing with now.
I hope this helps and good luck.

You were able to run the iPPC fans off of the video card pwm? I got one of the NF-F12 iPPC fans and when I plugged it into the card, it spun up at 100% RPMs and was uncontrollable through X1. I had to plug it into the motherboard to be able to control it. Did you get this one? https://www.amazon.com/gp/product/B00KFCR5BA/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

@bobh2000
I don't know what hardware you have, but i never needed a separate fan controller in the past 20y just to adjust the fans, no matter if mine or a rig i fixed at work.
Not even talking about the fact that ppl are supposed to spend additional money for something all decent boards can do.
And ive never seen someone running a +500$ gpu on a 50$ motherboard that cant regulate fans.
@Att1cus/JDauwalter
As long as you have decent fans from name brands, you should have no problems running 2 fans from one connector.
Example: im using silent fans from noiseblocker/blacknoise/arctic (between 0.08-0.3 sone) and none use more than 0.10A.
So technically i could easily run 8 fans and still be below the max of 1A
I recommend using 2 identical fans, so you dont need to worry about rpm mismatch.
It can be a 4pin on all sides, the controller will still feed both with identical signal.
If you need to adjust rpm, use something like msi afterburner, also easy to use for oc (max out sliders for temp/power, but NOT voltage).

If you want to run 2 x 4-pin fans off a single 4-pin header, this Noctua splitter is the best I've used, and as mentioned above, it takes into account only one of the fans should provide the RPM, while both receive the same power, and this allows the PWM to work as it should to regulate the fans speed in sync.

I like the using the SPLITTY9 for a fan hub and HUBBY7 for more USB 2.0 headers. Solid German engineering.

sure, but not needed. Rpm is not relevant for fan control, since the pwm signal determines fan speed. And since its not a MB header, even 0 rpm readout wont make any difference (e.g. setting of "broken fan" alarm). Not sure why anyone would need 2 fans. I dont know anyone that runs a LC gpu and air cooling on the cpu. With all rads blowing out, virtually no heat is added to the intake air (temp). Even that all my fans are silent (8db + rpm throttled), and swapped the fan from the 2080 with a silent one, my temps under gaming load (siege maxed at 1440p incl TAA 4x and MFAA in driver) i reach 55*C (stock fan profile). Shouldn't be that much more for the ti.

I just realized this thread is from the beginning of Summer (June) and was thinking that a bunch of rad fans were in need when a simple pair of splitter cables could get the job done. I must've been reading a custom cooling thread prior to this and never changed gears. lol

Yeah, only posted i saw ppl stating you would need a certain splitter or even a separate fan controller to make it work, and ppl spending additional money on something not needed.
