Big temps gap between two gtx460s in sli.

Is this normal?
In idle it is approx 10c delta or 38c vs 48c
At load it wildly fluctuates as much as 19c span or 89 vs 70c in some gane.
The warmer card is a primary card that gets the most air circulated around it than the other one.
Both are exact of the same cards made by GigaByte.
Should I worry?
Both cards are fairly new too.

Which card is hotter - Top or bottom?

 

[videopho]

According to MSI afterburner.
One nears cpu or gpu1.

What motherboard are you using ?
I have a slot spacing between my 2 -460's and run about 71 top 61 bottom.
I have the MSI cyclones and run the fan's near 100%, they are very quiet.
Which exact model do you use.
What case ?
Are your room temperatures warm ? Mine are at 70f
You might need a case with more airflow

top card is usually sucking warm air off the backside of the card under it.

on my SLI rig with 2 gtx 285s (and artic cooling extreme HSFs with 3 x 92s each) the top card runs 6-10 C hotter.

I believe this is fairly typical in any SLI setup.

In my 9800 GT SLI setup, the bottom card actually runs hotter at both idle and while gaming but I have 2 different manufacturers. The delta is smaller when I'm gaming and both cards are in use.

I bet if you swapped your cards you would see identical numbers and it is not indicative of one card having a more fatigued fan or inferior workmanship.

The primary card typically has more in use even in an SLI setup, since it has to actually power the connected display and coordinate traffice between the 2 cards.

I have the same in my 470 sli setup. Top card always runs like 10 degrees hotter.

So I guess this is normal for what it is.

I would say the same thing for my CF setup, the top card gets the heat

10C delta at idle or even load would be normal especially if they are next to each other, however, the 89C temp is getting a wee bit warm. mine started artifacting when it hit around 94C and moving it to the bottom didnt help. ended up RMA'ing the card. might keep an eye on the warm one just in case its starting to die like mine was. if the hot one has gotten hotter over time and continues to do so, it may be a problem. not saying it is, just throwing that out there. if thats as hot as it ever gets, it may just be poorly ventilated or the HSF TIM wasnt fully spread from the factory.

Sounds pretty normal. Top card should be hotter than the bottom, heat rises.
