Nvidia GTX 980 Owners Thread

Still rocking 1580/4040 on my 980GTX with 1.275v :) Been playing DA:I, Battlefield 4, H1Z1 and temps have maxed out at 63C only in H1Z1

Sorry, must have missed that.

Capped to 1212mv but it did clock to 1450 on that.

No problem, thanks. Was that a flaw specific to your model? Some one else reported the same on the EVGA forums. I don't understand why anyone would choose a FTW over an SC if it really is capped. I recently made the choice between these two models and since the FTW has only 1 display port and a lack of reviews I chose the SC.

My SC goes past 1500 comfortably in benchmarks at stock voltage.

The SC has a higher voltage referenced in the BIOS Stock. I can't remember what it is but I'm sure Neil can.

I sold the FTW and purchased a Classified - which I am very happy with. 1560 @ 1.2v. I may have a play with Kingpin's BIOS at some stage but it clocks good enough for me.

Hi all. So I have been playing around on heaven 4.0 for the last 6 hours now trying to get a sweet spot with my 2 kaf2 gtx 980s.Best score without hitting the throttle point was 3187 my cpu is at 4.2 hz.

The best I seem to be able to get is the boost clock to 1459 mem at 3800. Thats with no extra voltage power limit at 122% 130 cc and 350 on the mem in afterburner.
I seem to be hovering at 79 degrees on the top card with this set up so I dont throttle the bottom card is 68. Its so annoying as the cards are stable at 150 but the temps push over to 82-84 and I cant touch the voltage at all as I hit the throttle point and see the clocks drop down.

I have the phantom 630 case with 2 120 mm fans in the from 2 140 on the room for the cpu cooler and a 140 at the back.Also I have a 200 mm side fan and in a desperate attempt I even zip tied a 120mm high pressure fan next to the 2 gpus to try and cool the top 1 off!

Apart from going to the water route can anyone suggest a way that I might be able to control the heat a bit so I can try and push these cards?

:(

I am no cooling expert but have you tested just one card to see what the temps are out of SLi?

Also I would look at the airflow around the case. Static pressure is really important with all the fans working together in the the best way to move the hot air out. pushed in from the bottom and exhausted out the top and back.

As I said awhile ago, the KFA2 GTX 980's are awful for temps, they use cheap fans, naff cooling. You can pretty much knock 30C off those temps with an EVGA 980

I bloody wish I had know that before hand :(. Might replacing the fans on the gpus with another set up be worth while?Bloody shame the g10 kraken wont fit them :mad:

I bet the G10's will. I made them fit my small size PCB 970's. Temps were amazing.

I still have the two G10's was wondering whether to try one on my 980 as its a reference PCB and will probably fit no probs.

Not sure, but when I asked about coolers for the KFA2, they said it voids your warrenty

Hmm, i was hoping to replace the fans on my galax (KFA2?) gtx 980 HOF, as they get loud when running something intense, eg Far Cry 4 or AC Unity. As I've only had my system since december, i don't think it would be prudent to fiddle about with the card.
