980 TI Hybrid rad fan replacement question

[Xalindor]

ok so i have the EVGA 980TI Hybrid (the closed loop water cooled one) and i want to replace the stock fan on it with a new fan (already purchased dont try to talk me out of it) i bought this fan  
 
Here's the problem:
 
The cable that comes out of the video card is only a 3 pin male and the fan is a 4 pin Female. no problem right? well the shroud around the pins on the video card will not allow me to plug the fan into the video card. 
 
Temporary solution:
 
I have the fan plugged into the CHA_1 fan slot and then went into the bios and just made it always run 100% for now....obviously this is louder than I want it to be because it won't adjust for the needs of the video card.

Just pick up something like this (can't say I'd recommend that one because you can probably find a single adapter for less), or if you're a cheap bastard just take and snip off the part of the connector coming from the card that blocks you from plugging the fan in.

 

Hell until you do one of those things you could probably just run the fan at 40% or so and still have temps that are nice.

will I lose my PWM and be converted to DC if i Use something like that? Would the fan not run at full speed anyway? thx for the quick response.

Well of course you're going to lose PWM control and go back to DC, though I've had motherboards which control them fine (and the fans were okay with it), though how the card/your fan will handle it I'm honestly unsure of.

 

Really you might as well try to find a cheap 3-pin to 4-pin adapter and if it works brilliant, otherwise you have a new toy to sit on your desk and fiddle with.

Does anyone know of a Software that can make CHA_1 be controlled by Output of GPU temp? I tried fanspeed but i cant seem to get it to work on windows 10 and others have reported similar issues. tried running in compatibility mode with several different OS to no avail. seems like a simple thing to do =-(

There's no pwm from the 3pin fan header on the graphics card in the first place. For 3pin fans, a pwm signal that runs at 12v will result in 100% speed. 

If you plug a 4pin fan onto the 3pin graphics card fan header, you get the same dc control as you would when plugging in a 3pin fan.

The fan header on the graphics card already follows a fan curve reacting to the water temps. People who want a quieter fan tend to replace the stock fan with something slower.

Is SpeedFan not starting up?

Not really after a quieter fan i just don't want it running at 100% all the time.

No it starts and gives the correct readings but any changes i make to the speed of the fan does not actually make the change. followed along a video doing this exact set up so im sure I did it right.

Why don't you want it running at 100% if noise isn't an issue?

What settings have you tried in SpeedFan? What video were you following?

[Xalindor]

@WoodenMarker Would 100% constant up time not damage the fan over time? also it is a little bit loud at 100% I use my GPU to mine when not playing games (which honestly im usually playing games) that's when i would want it to spin up at max speed it is a little bit loud for gaming as i sit beside the tower. so i guess noise is a small issue but not the main concern. I would like for it to adjust with the needs of the heat of the GPU

 

 this is the video i watched. yes i watched the whole thing but this was the part where i made changes

No, it wouldn't damage it any more than normal wear from use. Fans are designed to run at 100%.

What SpeedFan settings have you tried and what video were you following?

@WoodenMarker

 

Good to know about damage on the fan. the video i was watching ( I edited it in probably after you posted) is below. I watched the whole video but this link will start you where i was following along. I set it to adjust at 55c ( never changed it to F as it says to do in vid) to 100% speed and i got no change. thinking i may have the wrong fan i adjusted all fans to go to 100% speed at 55c on vid card. started mining corsair link said card got up to 62c with no change in fan speed.

Double check to make sure that you're editing the settings for the correct fan by stopping the fan with your hand. The reading should change to 0rpm for the fan you're stopping.

I did. I'm positive i had the right fan. i was worried about damaging the fan doing that too lol but yea i did. i didnt stop it i dropped the speed way down but it changed on speedfan from 2500 RPM to about 1200 and when i let go it sped back up

Have you tried using the Temperatures and Speeds tab instead to control the fan? Setting the min/max value and enabling the Automatically Variated option in the Speeds tab and selecting the GPU temp in the Temperatures tab with your desired temperature should be enough to control the fan speed. I personally prefer this over the more complicated Advanced Fan Control option.

[Xalindor]

@WoodenMarker

 

This is the main page. i have the CHA_1 fan set at 100% in bios it is the SyS fan sitting at 2500 RPM (positive of that) 

 

I then set the speeds like this. the rest are all default 0 min 100 max not variated

 

 

 

 

Took a wild guess here...this might be where the problem is but idk. does this look right to you?

Have you set your desired temperature? It shows up at the bottom when you click on one of the Labels in the Temperatures tab.

@WoodenMarkeryea sorry meant to post that in the picture

With the desired 46c target, the fan won't stop ramping up to 100% unless it's below 46c. You should raise the desired temp to a target that the card can stay at while the fan isn't at 100%.

[Xalindor]

@WoodenMarker My temp is between 24C and 26C

[WoodenMarker]

What motherboard are you using?

Is Sys unselected for every other Label listed in the Temperatures tab?

   Yes

 

The rest of my build

[WoodenMarker]

Have you tried disabling the fan header in the motherboard settings or setting it back to Auto? Having it set to 100% could be conflicting with SpeedFan. 

[Xalindor]

@woodenmarker i was actually just trying that. i switched all the fans to standard. GPU went from 24C to 27C then I started mining to jack up the heat and it went up to 60C with no change to fan speed.

It could be that the fan controller on your motherboard isn't fully supported by SpeedFan yet. Relying on the graphics card fan header is probably your best option. 

[Xalindor]

yea I'm thinking the same thing (mainly cause im tired of screwing with it). do you think it would be ok to trim the plastic around the shroud or should i get the adapter previously mentioned. i can only find them in a 4 pack and only need one Correction I found 1 for $7 or 4 for $8. thoughts?
