I gave up. Returning the N980 to Amazon tomorrow. Just ordered the EVGA hybrid set. My 980 Ti started working perfectly as soon as I removed the N980 and reinstalled the stock cooler.

Same for me. The fan ran at 50% constant and I swapped out my 980 Ti fan for the one on the Corsair N980. It has been behaving. But now the computer turns off if Valley has been running for 10-20 seconds. Haven't been able to figure that one out yet.

Just to update: Well that was a relief. I just finished remounting, and re-remounting the pump to the card. Actually it was about 5 times but it got the job done. For me what worked with my H75 was: 1. Make sure the BIOS was telling the pump fan header to go 100%. (Apparently that is not always the case) 2. Loosen two screws on the N980 plate itself nearest to the IO shield. 3. Actually swap out the Intel pump mounting system for the AMD bracket. 4. Loosen the two thumbscrews nearest the IO shield and tighten the two other ones. 5. Get a plastic half inch pipe that I had that was 9 inches tall to actually fit under the rear of the card, near the power plugs, to prevent the card from sagging. All of the above is completely and utterly absurd. But right now my 980 Ti is sitting at 51° on Valley at 99% load, no OC yet. It has been running for about 20 minutes. This is just stupid tbh. Apparently the warping / bending of the card had been causing the pump to not properly make contact with the GPU die. Right now it is working for me but I'm quite honestly not sure this is something I want to keep in my system. The hours spent to get this running properly is ridiculous. Quite happy with the temperature but damn.

Reapplied TIM and reseated the H75 and pretty much identical temps. It gradually went from 33°c from boot to 85°c in about 5 minutes. After that I shut down Valley. Let the GPU get down to about 58°c and then started again and it jumped to 70°c in 2 seconds. Then gradually climbs above 85°c. Any ideas?

So I got the H75 installed on the N980 about 2 hours ago. The temperature is not ideal. It stays around 30°c at idle and gets up to 84°c full load. The pump is connected to a FAN_OPT header on the board running at 100% RPM. Got one fan on the radiator pushing air from the bottom of the R5 case atm. Might go push/pull to see if it makes a difference. I've tested tightening and giving the thumb screws some space with no change. You can actually move the pump slightly side to side on the cooler now. The plan now is to reseat the pump with something other then the stock TIM applied. Everything gets extremely warm to the touch around the N980 bracket and radiator. Much easier to maneuver the whole setup, which is nice this time around. Looks cleaner as well. Update once I've finished the reapply.

And after the sixth attempt... It went super smooth actually. I followed Corsair Dustin's advice on the installation here : http://forum.corsair.com/v3/showpost.php?p=819209&postcount=35 The fifth attempt went horribly wrong. I overtightened the screws so much that the PCB was curved like a banana. Temps rocketed to 85°c within seconds of launching Valley. What I changed the sixth time around is I watched to only lightly fasten the N980 backplate and only tightened the H100i pump finger tight in an x pattern. I also rotated the pump on the cooler and the hoses now face outwards from the motherboard. Right now the 980 Ti is sitting at about 27°c at idle and just hit right this second 66°c at full load running Unigine Valley at 1440p everything maxed. It is much better then the temps I was getting on the previous attempts. I am incredibly relieved right now :laughing: So to recap: 1. For me the stock Corsair fan was incredibly loud and seemed to vibrate. I removed it and installed the Nvidia stock cooler fan. It is much quieter and runs steady at 22% RPM according to MSI Afterburner. 2. Don't overdo the screws on the N980 bracket as it seems to bend the PCB. In my case the PCB was warping considerably and most likely causing improper contact between the pump and GPU die. 3. Once fitting the pump for your Hydro cooler don't tighten the bracket holding the pump with a screwdriver, only finger tight. 4. There seems to be no way around the fact that the N980 bends the PCB slightly. I can live with the bend right now. It's more like sagging at the rear. Here are some images for you viewing pleasure.

I'll post again once the H65 ships and that is installed in the bottom. Will post before and after temps. Also got some Noctua fans laying around that need to go in.

Just removed the Corsair fan and installed the stock cooler fan and it's night and day. The volume is what you'd expect at idle. But now the PCB is considerably more bent than before and the temperature rockets to 85°c in seconds after launching Valley. :sigh!: Will have to reseat the pump again. It seems to be incredibly finnicky towards the mounting of the cooler to the N980. This is my fifth time and I can't seem to figure out what is the cause of it. Here's to another intallation attempt! :sunglasse

Alright, then that 72°c is maybe not something completely bonkers. I'd imagine though the H100i would cool it better. What is your idle temp?

The temp is still sitting at about 72°c at close to full load on Valley. I am about to remove the setup again and attach the stock fan onto the N980 itself, see if that makes a difference with the fan noise. I would need a cable extension for the fan plug to go to 3pin fan header on the motherboard before I could test that out. The plan is to get a H65 and stick it at the bottom instead of the H100i atm. That has the circular pump and needs the seperate standoffs included in the package. I am starting to wonder if that will fix the temperature. Right now it is sitting on a cool 27°c idle temp. Either way there is something wrong with either the fan that came with the N980 or an incompatability with the PNY 980 Ti and the N980.

So I just finished the reinstall. The installation went smoothly. I forgot to mention before that one of the screws on the N980 won't line up with the PCB. This happened on all occasions I tried installing it. There are 6 total screws for the N980 plate to attach and the one in the middle row, facing towards the motherboard, was misaligned. See photo here: http://s29.postimg.org/5qlsxynuf/IMG_1145.jpg I added TIM and placed the pump on the H100i on top with the bracket. I tightened the screws more the finger tight with a screwdriver until they would not move any further. Once that was done the PCB was bowing slightly, see photo: http://s29.postimg.org/7wg3sgrav/IMG_1151.jpg I inserted the mangled mess into the computer and hooked up the two fans into the motherboard fan header and the pump to SATA power and RPM header into a spare fan header on the board. This is the ghetto setup atm: http://s29.postimg.org/ne3lw5xrr/IMG_1154.jpg. Once the system booted I started taking a video on my phone of the results. The fan is unacceptably loud at 22%. I tried MSI Afterburner and ASUS GPU Tweak to try and set the fan curve or total fan noise. You can see better (and hear) in the video how the fan gets ridiculously loud over 60%. I ran Unigine Valley at both 720p and 1080p to monitor the temperature. It peaked at about 72°c in the 1080p run. It ran for about 20 minutes. If I stop the fan with my finger it is barely audible at ~500rpm. According to HWmonitor it sit at 1660rpm at 22% (at least that was the percent MSI Afterburner was showing me). Here is the video: [ame] [/ame] Thoughts?

The problem also is the fact that the fan on the N980 seems to spin at 50-60% constant and I can't change the fan curve. I am in the middle of disassembling the 980 Ti right now. Will post more info as it comes up.

I went in an X pattern both times. I didn't dare tighten more then I already had the second time since the PCB was curving like mad. I tried moving the actual pump unit around on the GPU the second go around and try to see if it wasn't making decent contact with the die. As far as I could discern the pump sat flush. I am going to try again in a few moments. I will post photos and more info once finished.

I have similar results with my installation as mentioned by a few good fellow geeks above. Just bought the N980 for my PNY 980 Ti reference. After bolting it to the card I started on the H100i I had lying around and followed the instructions to attach it (without the included standoffs) to the new bracket. Two of the four screws holding in in place didn't tighten, they just kept screwing and bending the PCB the more I screwed them in. So I settled on a tightness that seemed to make the least amount of bending and most amount of contact with the actual GPU die. So now I hooked up two Corsair SP120 fans to the radiator and just hung the radiator to the side while I inserted the card into the system. Connected the fans up to the motherboard, the H100 pump to SATA power and 3pin pump RPM header into a fan slot and fired her up. Booted just fine. Noticed right away the included Corsair fan spun very fast and loud. Stopping the fan with my finger the system was completely silent. Launched MSI afterburner to see temps and at idle it was at 40°c. Launched Unigine valley for testing and kept afterburner open as a monitor. As soon as Valley launched the GPU temperature jumped to 91°c so I immediately shut it down and turned the system off. Puzzled I removed the getup from the system and removed the H100i, thinking it hadn't made good contact with the die. Nope, the TIM was applied and spread across 90% of the GPU. The pump had power and the logo lit up. The fans were spinning and everything was registering as normal. So I redid the TIM and tried again. This time around I tightened the screws more than finger tight like before and the PCB bent considerably. Reseated the card into the system and booted. This round it went exactly the same as before. After reading these forums seeing people recommending swaping the stock coolers' fan for the one Corsair supplied I decided to call it a night and reattached the stock cooler wholesale to the GPU. So, any thoughts on the matter? Something I did wrong? Please if you have suggestions let me know. I was looking forward to getting my GPU cooler and quieter.
