So I'm new to running two 2070 Supers on my rig. What are some custom fan curves for optimal temps for staying cool? Right now I just use the "aggressive" setting on both cards. Suggestions and advice is more than welcome!!!
"Optimal" temps are usually 100% fans on the cards and case fan speed balance that provides good air flow around the cards. You can test with smoke or fake smoke and a clear side panel (if temporary - thin plastic sheet) if you really want to get into it.
Personally I prefer a flat curve above a certain threshold, say 80% above 40C, thus it will lock in at constant noise level under gaming load and the temp will float with load/power. Then like 40% or 50% for idle / browser use, pick a temp where the fan speed doesn't jump around.
The main problem people seem to be having is not enough air flow getting to the cards, such as too much negative pressure by more top and rear exhaust than front intake, creating an air flow dead spot around the card where it sucks in it's own heated exhaust air. Having a front mount AIO cpu cooler radiator blocking all the front case fans can be really bad for these GPU's, not for air temp but lack of air flow.
Having 2-3 really strong front fans blowing unobstructed at the GPU end, sealed case top and lots (LOTS) of rear vents seems to work well for a simple setup. Neatly dressed or cables out of the way of air flow helps. Also don't want any drive bays or PSU shrouds blocking any lower front fans feeding the GPU's.
If you see surprisingly high temps you may have a mis-mounted cooler or poor paste coverage, it seems to be happening.
No mention of your SLI slot spacing, I assume it's 3 slots.
