The GTX 770 Cooling mystery

post #1 of 8
Thread Starter 
Hi all,

I recently had weird temps with my card.

Idle was: 49-50'C (with fans at 27%). Even with the fans at 100% the card would only drop to 43'C at idle.

The culprit, you might be guessing? My second monitor.

After unplugging my 2nd screen, temps dropped from 49'C to 39'C - a whole 10 degrees. However, even when pushing the fans to 100%, the card won't go under 37'C at idle.

Maybe some new thermal paste is in order? I have some Arctic MX-4, but others have suggested Coollaboratory Liquid Pro or Ultra.

Anyway, I wanted to put this info out there for reference. Notice the higher clocks and temps when the 2nd monitor is connected.

Before unplugging second monitor - high temps and a higher GPU clock.




After unplugging second monitor. Drop in temps and a much lower GPU clock

Multi monitor setups always run the card clocks higher than single monitor for idle, meaning you'll have higher idle temperatures. You should just check out load temperature, idle doesnt really mean anything.

Load temps are also quite high. I get 79'C in Battlefield 3 for example. Usually the second monitor is blacked out however during the game either way.

the first set of graphs have higher clock speeds and voltage. rather strange for a second monitor.

Is this a Nvidia thing? (not bashing, just curious. Calm down kids) I have no change whether its 1 monitor or 3 headscratch.gif

Sounds a bit out of the box, but is the cable or the connection for the second monitor on the fritz? or is it the monitor itself?

That's the weird thing. As soon as I plug in the second monitor, the GPU clocks rise drastically and stay like that.

I don't know if it's something to do with the cable, I doubt it. The first thing Gigabyte asked me was "do you have multiple displays connected?". It seems like this isn't uncommon.

its normal for the clock to change a bit but its still "idol" if you know what I mean, the temps should not change significantly, if at all

Multi monitors always raise the idle clocks,
there is many threads here too describing the same thing you have.

Not always it seems, I have 1920x1200 + 1680x1050 and get 135/162MHz and 0.875v on a GTX770, it may jump up for a few seconds when I launch certain applications but it always returns to the lowest state. Here it is with WMC playing live TV and FFox.



Try a basic theme or disabling desktop composition if you're really concerned about the idle clocks RichiRichX, that isn't the reason I disabled mine though, for me it's the only way to consistently see the second monitor while gaming fullscreen on the first.
