Hi, EVGATech_DaveB can you please tell me which Noctua fans have you USED for this rad? I tried on All-in-one GeForce GTX 980 HYBRID kit mounted on Titan X to use Noctua NF-F12 Pwm, but with no luck. I tried 2 of them but none of them hasn't started at all. I also plugged a small NF-A4x10 FLX, just to try - this one start with little help. All of noctua are 12V, 0.05A, 0.6W, but seems that they need more power/voltage at the start. Stock fan (which is loud like he'll) works fine, but I wish to change it for one of my Noctuas. Also my another question is, do this AIO kit do something with CONTROL fan speed or its just feed it with power ? Seems like it provide just power for fan, but I want to be sure.


This Post may Help you: Titan X and 980 hybrid cooler official thread Also the best place to ask this question of other Titan X Owners.
The Fan Power only have 2-Pins in a 3-Pin Connector. The AIO does not control the Radiator Fan as stated in earlier posts.
"Seems like it provide just power for fan, but I want to be sure." That is all it does.

Thank you for your answer bcavnaugh. I already fix Noctua fan on radiator and plug it into motherboard socket, but I will describe it in this thread with my results.

Wish I had seen this sooner, I just ordered two pairs of corsair sp120 quiet fans. Looks like it's 7 to 12 volts per fan so I think that is over the max it will support or I did my math wrong. I'll go double check.

I attached one Noctua NF-F12 PWM 120mm fan to the hybrid cooler's radiator, except I have the fan plugged into the motherboard, thanks to the GPU's fan being a 2 pin connection and the noctua being a 4 pin...makes no difference to me, I just tucked the un-used 2 pin connector from the GPU. (blower fan is still moving as well without the 2 pin connector being connected to anything, so...?)

Will the fans still spin up as heat rises on the card or are you left manually adjusting it?

I honestly have not noticed(I'll try to pay attention the next time I'm having a long session, but I doubt it, it's probably what it's for...though I have tested manually changing the GPU's blower fan with EVGA's PrecisionX just to verify it does work, and it does.) However, I have not changed my GPU's fan settings at all, the highest temps I get playing GTA V is 41-45C, I have never gone over 45C no matter how many hours I'm gaming. That might be a little higher for me due to my ambient temperature with living in Hawaii and all, but I do leave all of my noctua's in my case at 100% use as well, including the one on the radiator, still super silent and cool.

This may be a silly question but the the only AIO I have used is the Corsair H100i for my CPU.  With this as most probably know I power the radiator by plugging the AIO into a Sata power connector from my PSU.  I then plug my Noctua F12's into my motherboard as I don't use Corsair Link.
 
So with the EVGA Hybrid I was going to use another Noctua F12 I have on the radiator and as the poster above said I was just going to tuck the GTX's cable away since it won't be running to the radiators stock fan.  However I got to thinking, how is the pump itself powered?  Like with the H100i the unit plugs directly into the Sata power connector.  But of all the EVGA Hybrid kit's I've watched get installed on online I never see anything plugged in from the actual GPU cooler/header.  All I ever see get plugged in is the stock radiator fan to the vid's PCB.

EVGATech_DaveB, I plan to replace the stock fan with Noctua NF-P12 PWM. Can the 4 pin pwm powered by 2 pin hybrid male cable ?

Since it is a boxed 3pin connector, I do not think you can without adapters, it will not connect straight through.

This is precisely what some of us have been looking for. There are many, many, many different fan adapters available - PWM male to 3-Pin female, 2 pin to 3 pin, et cetera.
 
I have the hybrid kit (Titan X, if it matters), and a Noctua NF-F12 fan. The Noctua fan has a 4-pin PWM connector, yet the Hybrid unit's connector only accepts a 3-pin header.
 
You mentioned an adapter, but.. what, exactly, kind of adapter should I be looking for? A link would be *excellent*.
 
Thank you!

This is kind of an old thread but to date I have not found one myself so they still may not make one.

I am using two NF-F12 1500rpm PWM fans on the Hybrid connected to the motherboard and controlled with Speedfan.
Fans are kept below 900rpm and temps are in the low 50s.
In Idle the fans are slowing down to 250rpm, are inaudible and GPU is around 30°C.
Loudest is unfortunately the Hybrid pump.

Odd that the temps would be lower with a lower fan speeds.
My Idle Temps are about 28C and at 1500MHz running 99% the Temps are around 36C and the Max is about 38C today.
I have mine setup as Push/Pull ATM and 100% Fan Speed for Folding and currently Crunching on GPUGRID

Sure. I just switched the 2xVadar fans on the Hybrid for the NF-F12s some days ago. Also using 2mm thick shrouds on each side of the rad.

Are you pulling air into the case or are you pulling the hot air from inside the case out through the radiator and out the back of your computer?
 That is what it looks like for your CPU Radiator. Where is your fresh outside air coming in at?

Pushing air out, so the air comes from the front 3x120mm (also push/pull) and exhaust with 1x120mm. But currently the 360 in the front is releasing almost no heat into the case with the 5820k@4.5GHz with 1,25v.
Highest temps in games are 53-54°C

In the Front and out the Rear, I see them better now.
I would put a 120/92/80 on the Bottom of your case for pull in some Cool Fresh Air.
 
Is that a 980 or 980Ti
If a 980 your Temps seem really high.

980Ti. I prefer a quiet setup, not high rpm and very cool. Running the fans at full speed wouldn't give me any major benefits. So this is my preferred noise level with still good temperatures.

Yes and also the 980Ti runs hotter than the 980

Re: Can The GeForce GTX 980 HYBRID Support Two Fans with a Y-Adaptor? 2016/06/11 06:56:37 (permalink)
Sorry for the very late post, but got curious as to why EVGA decided to only use a 2-pin connector to power the radiator fan on their hybrid cards.  Makes absolutely no sense to me.  Use of a 3-pin should have been standard and would have allowed for the pump thermostat to control the radiator fan.  A 4-pin fan would have been the best as it would have been compatible with whichever fan the customer wanted to use; 3-pin or 4-pin.  In the end, I have two suspicions:
 
1) EVGA engineers decided to use a 2-pin cable due to power limitations with the voltage output from the pump which may negatively impact pump speeds (and flow rate) should GPU temperatures rise above a specific threshold.  Adding voltage to the fan in such circumstances would actually slow the pump down.  Use of a 2-pin connector resolves this issue by making the radiator fan run at one constant speed and also would keep fan noise at a minimum.
 
2) EVGA cut corners and used defective AiO cooler units from the manufacture.  My guess of the defect?  A bad thermostat inside the pump housing which won't allow a normal 3-pin or 4-pin fan control cable to function correctly and vary the fan speed.  The manufacturer simply replaced the stock 3-pin fan cable with a 2-pin cable and problem solved.  They are able to get rid of defective units in bulk.  Whether or not EVGA would be aware of such a tactic is anyone's guess.
 
Okay, I'm finished with my 'conspiracy theories' for today ;-)

3pin = 4rd pin sends tacho signal.
That is not required

I understand that.  I'm referring to why does the fan cable provided for the radiator fan only have 2 pins?  Hence, my theories as to why EVGA did this instead of providing a proper splitter for the PWM fan header  which drives the blower fan and the radiator fan.  Amazon sells PWM fan splitters which also have a MOLEX power connector to augment for the additional voltage required to power the additional fans.  This is one area that I really do hope EVGA improves upon with the GTX1080 Hybrid.  Having a second 8-pin power connector will easily facilitate having an additional PWM fan header provided on the card's PCB without having to use cable splitters and allow for much quieter radiator fan operation.

I would think to separate fans from the fan controller, EVGA Precision X manages the GPU fan only, Blower or ACX.
To be able to control two separate fans you would need two controllers on the PCB, this would then need more power overall.

3pin = 4rd pin sends tacho signal.
That is not required


I understand that.  I'm referring to why does the fan cable provided for the radiator fan only have 2 pins?  Hence, my theories as to why EVGA did this instead of providing a proper splitter for the PWM fan header  which drives the blower fan and the radiator fan.  Amazon sells PWM fan splitters which also have a MOLEX power connector to augment for the additional voltage required to power the additional fans.  This is one area that I really do hope EVGA improves upon with the GTX1080 Hybrid.  Having a second 8-pin power connector will easily facilitate having an additional PWM fan header provided on the card's PCB without having to use cable splitters and allow for much quieter radiator fan operation.


I would think to separate fans from the fan controller, EVGA Precision X manages the GPU fan only, Blower or ACX.
To be able to control two separate fans you would need two controllers on the PCB, this would then need more power overall.


That's what I said in my post.  Did you actually read the whole thing?

It is my Thread after all and Yes I did read the whole thing.
You did not say anything about two controllers on the PCB, did you actually read the whole thing?

Hey guys!
I'm planning to do a push/pull config for my Titan X hybrid with a Y-splitter for 3-pin fans. And i'm going for Noctua fans. Between these two:
NF-F12 industrialPPC-2000rpm 3-pin (
NF-P12 1300rpm 3-pin (
Which one would you guys suggest for the safety and best performance?
As EVGATech_DaveB stated that the max is 19.2W. I read that the max input power for the 2000rpm version only takes 1.2W and 0.1A. So two of them only take 2.4W and 0.2A. So it will be absolutely safe to run those two 2000rpm fans with a Y-splitter on the hybrid cooler?
Thanks!!!
