GTX 780 3-Way SLI - Page 3

post #21 of 22
Im using 3way SLI with the GTX 780 Factory Overclocked by Gigabyte (3Fans each).
My configuration: i7 3970x oc to 4.8 Ghz cooled with Corsair H100i
16GB Corsair Vengeance 2400 Mhz
480 GB Corsair Force GS
Asus Rampage 4 Extreme

My Problem: the Top Card reaches a Temperature of 92c
The Middle one at 85c
and the bottom one at 78c.

I think these temperatures are too high! Dont really know what the solution is. Note that these temps even arise when my case is open at one side.
If i would close the case, the temp would go up and stream through the radiators of my CPU Cooler, what results in bad cooling for my CPU. I dont even dare to
close the case. TO avoid this temp Hell i would need to install an Airplane turbine, where the noise would be so loud that gaming doesnt make fun anymore!
Thats not why i spent so much money and work to make this machine work.

The FPS are amazing reaching 230 FPS with Benchmark apps.
I used to have 2x GTX 690 stock (Asus) and didnt even reach half of 3way GTX 780 results.

My question: what could be the reason for overheating? Is there a solution?
I have a 2 year old daughter and cant keep the case open, can only play at night when she is sleeping....


Please let me know if there is a solution....


P.S. I didn't over clock with software at all since this would increase temps even more...



Thanks

I have 2x MSI GTX 780 reference cards and 1x MSI GTX 780 Gaming OC in 3-way SLI and I was also hitting the mid 85*c with the middle and top cards, however I mounted a Scythe Ultra Kaze 120x38 on my side panel. This fan has high static pressure which is great for 3 way SLi air cooled cards. Now the middle and top cards hit 80*c max and the GPU Boost is now better than ever. The lower MSI GTX 780 Gaming card with the TwinFrozr IV cooler now sits around 74*c instead of 78*c.
