4-way SLI (580 Hydro Ultras) to 2-way 780 Hydros?

post #1 of 2
Thread Starter 
Okay so I just recently purchased the NEX 1500 PSU and ever since then I have powered my 4th 580 and now the computer is overheating and cutting itself off after around 2-3 hours of gaming (48-60C), I am thinking of replacing them with 2x 780 hydro's, do you think this will help with the overheating issue?

Thanks

Sure it will help. But not need for hydro. First two cards will run MUCH much cooler than 4.
Second Kepler (780s) will run anyway much cooler than Fermi (580s).

No need to spend money or deal with the headache of water cooling GPUs unless you enjoy heavily over-clocked unstable hw.

But even with your current setup you can lower your temps with :
Reapplying TIM and cleaning fans.
and/or
connecting your main monitor to the bottom card (the coolest one)
and/or
adding more fans to improve case airflow. Especially beneficial is a side fan with high static pressure blowing directly to the side of the top cards.
and/or downvolting and dowclocking the upper GPUs. The effects in performance will be minimal in quadSLI and abyssimaly small if you have your monitor in the non down-clocked cool card
