How can I lower temps?

I7 5820k@4.5ghz
2x G1 Gaming 980 Ti's +100 mhz core +125mem +12v
Asus x99 Sabertooth
16gb 2400mhz Ram
850 Evo 250gb ssd
3tb Toshiba 7200 HDD
Corsair Rm1000I
H100i Gtx

I was just able to get my graphics card up to 91 degrees by using firestrike ultra and customizing it even more demanding than the stock settings.

I have 3 intakes and 3 exhausts.

I have ~1 inch between my cards but i might be able to move down another slot.

Ambient temp?

 

[bobbypie67890]

75 F

 

[Finkledbody]

what kind a case?

Corsair 780t

Download EVGA PrecisionX and set each card's fan curve to aggressive, that should help with the temps.

http://www.evga.com/precision/ or download it through Steam.

Or you can set a custom curve. Also make sure the box is active on the bottom left side "Start up on (Windows Logo)" to make sure the settings stay active.

Did that already

How about reverting the OC back to stock clocks? Does that help? You do need to get those temps down a bit, max temp is 92C.

That's why I asked in my topic "how can i lower temp" and tried that already as well

 

[WildCard999]

How about gaming? I'm pretty sure Firestrike Extreme pushes the cards much higher then most games. If your games stay well under 90C then I wouldn't be too concerned. I know Fire Stirke pushes my SLI top GPU to 88C and during gaming with the Witcher 3 or GTA V the tops GPU only goes to about 83C.

 

[bobbypie67890]

If I let my Gpu get to 99% usage in games itll hit 91

 

[WildCard999]

You could also try to increase your case fan speeds* as well.

 

[bobbypie67890]

I have tried that already too

This is the thread that I'm currently on with a guy look at this to see what I have and havent tried

 

[WildCard999]

If none of the above solutions help then you may want to consider putting in a custom loop or buying/running an A/C to drop the ambient temp. One last thing to check is that all the fans on the GPU's are they spinning?

 

[WildCard999]

If your within return period then maybe getting the reference versions of the card, should run cooler in SLI since they exhaust the heat out of the rear of the card and out of the case.

 

[bobbypie67890]

How much of a temp drop cud i expect?

 

[WildCard999]

IDK, but its gotta be better then what your getting now, even though the safe temp is 92C you should be significantly lower even on high loads.

 

[WildCard999]

I found a review for 980ti's in SLI, your temps should be alot lower.

[bobbypie67890]

I could really expect a 20 degree drop?

 

[WildCard999]

I doubt it would be that much, more likely at 7-10C drop. Also don't expect the temps to be as low as that review since they have a lower ambient temp but the temps should be much lower then what your getting now.

 

[bobbypie67890]

I think I will dump antifreeze in my room and see what happens to my ambient temps

 

[WildCard999]

Might be easier just to switch to reference cards.

And you've independently verified the gpu temps? For most OC, you'll not need to raise the voltage to remain stable, and the G1's already have a decent OC, raising the gpu voltage on those cards will show very little gain.

Some of your issue maybe fan related. Most case fans are very broad radiating, but the 780t is a huge case, and you have a major heat source where there is no airflow, namely the mid left section above the psu, right where the gpus are. Try switching up a couple of fans, slap the case fan temporarily on the rad, and stick the rad fan down on bottom intake. Rad fans generally have higher SP, meaning the air will actually make it to the back of the case. Worst case scenario, stick a fan on stilts and stick it to the top of the psu (low rpm, 400-500, you want to move the air away from the gpus, not overpower the gpu fans)

My 970 at 99% usage on MGS:TPP at ultra settings and 2k resolution with fans at 67%, 23°C ambient in a define R5 (in a cubby, not open air) only sees 62°C. 90 is way too high. If stock voltage and good airflow won't drop valid temps, you'll need to look into a full custom loop, which should be viable in your case since it has 2x triple rad possibility.

I have quite literally done every type of temp testing, game teseting, benchmark testing, and fps testing you will commonly find on the internet. I have two problems my temps are too hot my computer isnt performing right even when the gpus are in the 65-80 zone

Return the cards, get Asus STRIX or msi twin frozr, coolest running of all cards
