SOLVED - GTX 980 - 100% fan at 92C in one box, but normal in another

Edit: Solved. See last post.

Guys, I'm totally stumped on this one. I don't hang out in any dedicated tech forums, so I'm hoping one of you experts can chime in.

I'm shuffling video cards around. The GTX980 was in an i5-4690K box, on a mild 4.2GHz overclock running on a MSI Z97 PC Mate mobo. The box I'm trying to move it in to has an i7-4790K with a GTX960 currently, running stock clock up to 4.4GHz on turbo on a Gigabyte Z97-Gaming 7 mobo.

All is well on the i7 box running the GTX960, playing any games it is all but silent with the GTX960 hovering around 60-65C so the fan is barely even spinning. As soon as I swap the GTX980 in here, before the game even starts the GTX980 rockets up to 92C and the fan pinned at 100% at over 3000RPM. The happens on all the games I tried running. The only way to tame it is to run it in a 1366x768 window LMAOEEK!Mad It is not an issue of airflow in this box. I opened up both side panels and it made no difference, plus the fact that the GTX960 runs cool and silent much of the time, as well when I quite the game with the GTX980 temps immediately drops and fans stop shortly.

I move the GTX980 back into the i5-4690K box, and temps hover in the 70's C with the fans at 70% at most, running the same games from my Steam library. I'm at a lost here. It seems to me the Gigabyte Z97X-Gaming 7 mobo is causing the GTX980 to go nuts.

I'd appreciate your thoughts on this.

Did you reinstall drivers when you moved cards?

Are both cases dusted out?

Yes, performed clean driver installation.

The i7-4790K case is new, so it's spotless. It's a Super Micro S5 Platinum. I just built this box. Great case. I upgraded the 2x front 120mm fans to 2x 140mm intake, wasn't really necessary other than aesthetics. Conversely, the i5-4690K case is an old Corsair 300R case, not exactly spotless, and the GTX980 runs fine in it.

I'm so lost on this one..

Ya it's confusing. Bios updated on each board?

PSU healthy on both?

You might make a post over on Reddit.com/r/buildaPC.

No. It's the typical setup - dual 140mm front intake fans, CPU fan blowing out into the back, with a single 120mm rear exhaust fan.

I give up. I went as far as reflashing my mobo firmware. Something this mobo is doing that is causing the GTX980 to go berserk. Before the games even start, the temp shoots straight up to 92C and the fans pinned at 100% and stays there until I quit the game, or run it at a super low res.

This is one of the weirdest things I've seen, and I've been doing this for over 25 years. Have a look at the temps in the screen capture from my 4790K box vs the 4690K. My original plan was to move the 980 into the 4790K, and put my new RX480 into the 4690K. Because I can't use the GTX980 in my 4790K box, I have to scrap this plan and return the RX480 Frown

Yeah, I went as far as clearing CMOS on the mobo and reflashing and running all defaults, even flash the BIOS on the GTX980 itself. All to no avail. I've got a new EVGA SuperNOVA G2 650W in there.

I've never really try getting on Reddit before. It's very hard to find the topics I'm after. Like the r/buildaPC subforum you posted, I couldn't find it without your URL. I'll give it another look. Thanks.

Lol yeah, except that the fans are wailing like a jet. I had the Asus tweaker utility open as well. I manually slowed down the fans and the temp kept rising. Touched 96C before I killed it. It actually startled me when I first fired it up. It shot straight up to 92C and fans go from off to 100%.

I solved the problem. It was caused by EVGA Precision X. I just remembered this morning that I had this installed a while back. Never caused any issues with the GTX 950 or 960. As soon as I uninstalled it, popped the 980 back in, now temps are 75C and fans 50% max on load. If I enabled vsync, it's only in the mid-60's.

Just thought I'd update this thread in case anyone runs into this in the future. Now I can experiment with the RX480 in my other box, and hold off on buying the 1070, although the GTX980 seems perfect for my 1440p monitor.

Interesting, thanks for the update.
