SLI temperatures

post #1 of 9
Thread Starter 
Hello!
I would like to know how big impact on temperatures does SLI have.
SLI owners, please put here the following:
  • manufacturer
  • model
  • how many cards
  • oc?
  • cooling
  • custom fan profile? (when stock cooling)
  • max temperature in SLI
  • temperature difference between cards
  • max temperature with single card (if you have tested)
  • your case cooling (how many fans)

2 Way not too bad, top card can be upto 10c hotter worst case scenario, 3-Way and 4-Way can work without temp issues if your using reference design cards. Non reference will cause serious heat being dumped into your case having an impact on not only GPU temps but CPU too. Also most non reference designs make anything beyond SLI impossible due to their size.

Ideally anything beyond 2 GPU really should be water cooled imo.

I know all the things you wrote, but I just wanted to know how it is from global point of view.

I consider buying second reference 780 and wonder how much higher temps should I expect.
post #4 of 9
Your temps on the top card might be 5-10c higher at worst. I run a worst case scenario dual 670 setup. It uses ASUS DC2 coolers on both cards and I have a sound card smashed in between the GPUs. The sound card covers up one complete fan on the top card and a small portion of the second fan. there really is quite little airflow unfortunately and that makes my top card 10c higher than my bottom one. But even overclocked on both cards the hottest card still stays at about 65c as its max temperature with a properly aggressive fan profile.

My reference cooled single MSI GTX 780 gets up to 75C after OC (custom, aggresive fan profile).
I wonder if it will get more than 80C when I add second card.
post #6 of 9
EniGma1987 already answered that question. You can expect your temps to raise into 80-85C on the top card due to reduced air flow, if you do not optimize your fans.

evga 680 ftw 4gb w/ back plate in tri sli setup running all stock
gpu 1 slot 1/2 (2 slots to breathe)
gpu 2 slot 5/6 (sandwiched)
gpu 3 slot 7/8 (plenty of breathing room)
lian li pc-7h case with solid positive case air flow. (test bench install w/ big fan blowing yielded same results)

bf4 gaming load
ambient 27c
gpu 1 is 83c
gpu 2 is 91c
gpu 3 is 83c


most sli setup are configured wth slot 1/2 and slot 4/5 with one slot of breathing room between. as long as you have solid positive case air flow. reference or aftermarket will not matter. if your air flow is questionable. definitely reference.

I use a MSI z87 g45 and it gives me extra space in between my Galaxy HOF 780 and my reference evga 780 with a prolimatech mk 26 on it (the bottom one). The HOF definitely gets warmer, due to the mk 26 being larger and having 2 corsair sp 120 fans on it. What I do, is overclock both the card, but set the power target to 80%. This drops the voltages of both but usually it maintains the stock boost speeds or greater, but keeping the card 5-10C warmer. This also does drop my power usage from the wall about 100 watts during BF4.
