GTX 660ti Question

[Spinny99]

I have two GTX Reference 660ti's, and when gaming and overclocking, one of the two cards runs much hotter than the other.

Here are some pictures while playing BF4, and as you can see the cards are overclocked:

GPU 1:

GPU 2:

It's the latest version of Percision X. My motherboard is the Z77A-G45 by MSI. My CPU is an i7 3770k.

What could be the issue...

Hello... inspect the thermal compound and heat sink mounting... I have seen problems with assembly in the past, and are easy fix's.

One card is the primary for physx while the other one is probably handling the other details. They aren't going to be exactly the same usage. One is goign to work harder than the other. Just depends on what's happening.

I don't want to open up the card, it'll void the warranty. Also, It's a 50 degree difference, so I'm not sure if it's just normal PhysX stuff. The pics didn't show for some reasons:

What are the 2 temps at on avg?

 

[Spinny99]

I'm not playing any games right now and not overclocking, the 1st card is 36 degrees and the 2nd card is at 31 degrees. I really only see the major difference when gaming.

Can you boot up a game and let us know the temps while it's running that game?

BF4 does not use PhysX.

Those temps show that the second card isn't being used, is SLi enabled? Try turning on the SLi indicators to see if the game is SLi enabled.

It was just an assumption, don't have much to go on, also, the fact that it doesn't use physx could prove my point even more so. even in SLI, the 2nd card isn't going to do much unless the first card needs the help.

My cards spread the load evenly, do yours do something different?

 

[deadmaufive]

Yeah, mine goes until my first card hits a point where it feels it's either too hot or too much work for it, then the 2nd one picks up the slack and it evens out, but if my first card handles everything on its own, the 2nd card basically just sits there. I don't mean the 2nd card isn't doing anything at all, it's just not going to put a lot of stress on itself like the first card would. You'd have to be doing something insane to put stress on 2 660ti's.

My cards max out on BL2 and BF3 as well as a couple of others.

 

[deadmaufive]

I have 2 660s (non-ti) in SLI and handle BL2 without maxing out, but it does actually use my 2nd card more than if i were just playing WoW or something. idk, though.

Just checked, SLI was disabled LOL! They're now running at the same temps! Thanks a bunch for the help guys!
