Help with 980 ti hybrid radiator fan and alternatives.

[pipboy 3000]

Hi, i've just built a new system that includes the EVGA 980 ti Hybrid. I have a few issues.

The fan on the 980 ti radiator seems to be spinning at 100% all the time regardless of load and there doesn't seem to be a way to control this. MSI afterburner and other programs can only control the blower fan on the card. I've done some research and this appears to be quite common. Some say it's normal and other's say that it isn't and the card should be adjusting the radiator fans' speed based on temp, it's difficult to tell what the consensus is, either way there doesn't seem to be a way to control it manually and mine seems to be at 100% with the GPU temp idling at 28C. This is driving me crazy as the fan running at full speed is super loud. Can anybody shed some light on this?

As an alternative some have suggested that if the fan can be connected to the mobo instead and be controlled independently. i also have a spare 120mm PWM fan lying around and I'm willing to try this but i have a few issues.

I only have 2 fan headers on my itx board, a CPU fan header which i have a H100i GTX connected to and a 4 pin SYS_fan header. Currently there is a 3 pin chassis fan connected to the SYS_fan header. Can i get a 4 pin pwm splitter and connect the 4 pin gpu radiator fan and 3 pin chassis fan to it and still be able to control the GPU radiator pwm fan? If so, can anybody suggest a program that can be set to control fan speed according to GPU temps?

Thanks in advance.

You can indeed get a splitter. http://www.newegg.com/Product/Product.aspx?Item=N82E16812162026 That's a good one btw. I have several in my system.
I like the idea of hooking this up to the mobo, with this caveat. The fan curve you set up, will be dependant on cpu temp, not gpu temp. If you have a beefy cpu, you might not get the temp up enough to get that fan working, when the gpu temps would dictate that it needs to go way up. My preferred option would be this. Swap the fan that's on that radiator for one that's both quiet and powerful(I'm thinking a Noctua F12 PWM, or even better that 2000 rpm industrial). That way you can run the fan on a higher speed at all times and have it still be quiet. The F12 can run at 90% of max speed and still be quiet, all the while giving you good airflow, likewise the industrial could be set at 60% or even maybe 70% and be inaudible, while again, giving good airflow.

You might want to hit up the manufacturer to see if an update bios is out.

Connecting them to the motherboard, as you mentioned, would work if they are just regular 4 pin fans. Use a splitter if you need to.

There must be something that controls these fans and if they are running at 100% all the time with no way for you to fix that I would consider the card faulty and ask for a replacement.

The kit comes with a fan splitter that attaches to the cards original fan header.
Section 12/13 of the install manual shows how to install it .

Doesn't this just cut the speed down? Could be a problem if you need that extra cooling.

I have the latest drivers installed from Nvidia, also tried the drivers from the EVGA website which redirect to the official nvidia 362.00 version. I'll try to get in touch with evga.

I actually already have that splitter, will i be able to connect both the 4 pin and 3 pin fans to it? If so, will only the 4 pin fan be controllable?

Your mobo fan curve will treat them the same, yes. If, what you have in your system now is not loud, then either of the Noctuas I mentioned would be fine. If it's a noisy, powerful fan, then you'll probably want the 2000rpm, to push the normal operating pulse modulation to a lower amount. I would think that under most scenarios, 1200-1400 rpms from an F12 Industrial will give you good cooling, while still being quiet.
I've learned some of this stuff the hard way, myself. My stupid graphics cards have mediocre cooling(twin frozr MSI cards) and need all the help from powerful case fans they can get, problem is, what to do when the case fans are running at half speed cause the blasted cpu runs cool.

The splitter connects to the video card itself.
You disconnect the original fan cable. connect the splitter to the card pins.
then connect the original card fan and the radiaror fan to the splitter.
The card will adjust both fan speeds as needed, depending on temperature.
You can also use Precisionx, Afterburner etc.. to set custom fan profiles.

That's the ticket.

Only 4 pin fans can be controlled. 3 pin fans do not have PWM.

NOT TRUE.
Many motherboards,power supplies and video cards can control 2 or 3 pin fans.
They are controlled by voltage. The lower the voltage the slower the fan spins.
You can also buy or make low voltage extensions and splitters.
To make a 7v low voltage connector you use the 12v yellow (+) wire and the 5v red (+) wire to achieve 7v.
If your motherboard does not have enough headers you can make your fans run at 5v, 7v, or 12v.

Sounds perfect, will any splitter do or does it have to be the one that comes with the kit? You would have thought the hybrid model would have already have this pre installed.

In case you do not have it .
Here are the instructions on installing it.
You need to look at 12/13 sections.

I got to admit I'm a fan of the hybrid but that's something I don't get as well and why its not thermally controlled with the rest ?? go figure

some guys I think were replacing the evga fan with a low rpm fan [like 1600 rpm] that pushes the same amount of CFM's -

whay I also find funny is that evga don't seem to be able to address this or theres a reason they have not ??


now check how this guy got satisfied

''I received the new card today and can confirm to all Nvidia evga 980ti hybrid owners. That the radiator fan is adjusted by the card when the temperature rises or lowers. To confirm this i plugged the radiator fan from the old card to the new card and it went whispering quiet. This means that the Card's fan headers are faulty, so if you own a Evga 980ti hybrid and are wondering about the loud radiator fan its the headers and not the fan. Its a RMA from where i see it.

http://www.tomshardware.com/answers/id-2929283/evga-980ti-hybrid.html

so he rma the first card that I guess did like yours and got a new card and it works as he expected ???

it should be thermally controlled not 100% full time just spin up and down as the card heats and cools [radiator fan ]
good luck

Splitting hairs. I said only 4-pin fans have PWM, which IS true. 3-pin voltage control sucks compared to PWM. It has limited stepping and compatibility is an issue. We could argue semantics all day but voltage control might as well not exist because it is far inferior.

 

[junkeymonkey]

thing is the cards fan is electric controlled the radiators is thermal controlled - like that guy had onr that ran 100% and got a new card that spools up and down with the temps

from the toms link I gave above ??? now I guess its between him and evga on whats next to resolve as he did .. you could do as you feels best but for 700 bucks I'd make evga make it right

you could send that guy in the toms link a private massage and see if he will help on what went on with his and if its still all good with him today ??

good luck

It really depends on the controller used.
My motherboard will control 3 or 4 pin fans just fine.
From a low of 400rpm to a max of 1600rpm with very fine granular adjustments of about 50rpm steps throughout it's full range.
Manual wiring of 5v,7v,or 12v is as you describe and some fans will not start at 5 volts.
And yes 4 pin PWN is much easier to set up than 3 pin systems, but when set up properly in the bios, you could not tell which a system was running without looking at the connectors.

If you look back at your post you specifically said "Only 4 pin fans can be controlled" and that is why I said you were wrong.

My x99 extreme4 won't even control 3 pin fans. I find that more and more motherboards are opting for PWM. I just wish PWM fans wouldn't charge extra. It hardly costs anything to implement it.

I was wondering if this was you here ??

notice how the evga tech reps have not answered ??

i'll point out once more the guy I linked above that card ran 100% and he got another card that did not and worked fine as you expected it to ?? hmmmmmm......

to me as well why on a card that runs so cool should a fan only run at 100% all the time ? don't add up and funny only a hand full of guys run into this and report it or complain of it ???

'''EVGA has also taken a different approach to fan control than MSI. The 120mm radiator fan is attached directly to the card’s internal header so core cooling is based on water temperatures rather than a random set of motherboard-based variables ''

Yeah that was me, I'm really confused now. The explanation the user on that thread gave about how the fan is always at full speed made sense however I'm surprised an evga rep hasn't responded directly, I will be emailing evga support to try and get an official response from them and then take it from there. Plus that last paragraph from the hardware Canucks review states that the radiator fan RPM is managed, indicating it is not always at full speed. Thanks for your help.

 

[junkeymonkey]

I tried to see if the guy in the outher toms post I linked above would answer but so fa he's not ? that's the thing like him he got another card and claimed the replacement worked as expected with the temp controlling the fan ??

they may not answer direct to help avoid a few rma's and hope you believe it just the way it is and ''you'' try to resolve it some how like replacing the fan yourself ???

to me it seems funny like I said above a card rund so cool what is the fan needing to run 100% full time ?? its not like you got a cheap mid range card

like at newegg reviews you most see '''Pros: - Currently sitting at 25C on idle.
- So quiet I had to open the case to ensure both fans were running.''

then theres that 1 or 2 with the ''Cons: stock 120mm fans that come with the cards are two wire and not temperature controlled and run wide open always. even if not needed (idle gpu) so they can be noisy. replaced stock 120mm fans with some quieter units that are controlled by gpu temps''

http://www.newegg.com/Product/Product.aspx?Item=N82E16814487144

you would kinda think that would be well reported as a con ''fan runs full blast all the time '' ??? but you don't ..

don't know ? I guess its now between you and them on satisfaction ??

[heck , copy and paste all that over to the evga thread and then let them crawfish on it they will back it up or they will call there own guy a liar ]

 

[junkeymonkey]

looking overyour evga thread today you seem to now have them between a rock and a hard place on this ..

so whos a liar the evga rep that says dynamic and works wit the temps or the evga rep that says constant full speed ?? they both cant be right and why they now cant officially answer you ..

anyway they now answer that show they misrepresented there product and scared that will cause a rush of rma's / refunds - you got them good ....

also look at newegg under the overview tab

'' Virtually Silent Operation

Variable controlled fans allow dynamic fan speed based on GPU temperature, and the water cooling efficiency means very low noise fans.

notice how they worded it ''fan's '' not fan ?? as well

http://www.newegg.com/Product/Product.aspx?Item=N82E16814487144

don't let up on them


so heres his resolve from evga forums on all this mess he claims in private messages he not able to post back for some reason ??
