Cards showing big temp difference?

[JAMlE]

Ok so I just installed 2 x 280x's in my system and card 1 is showing 48 degrees but card 2 is only showing 34 degrees. Is it normal to have this big of a temperature difference? I have plenty of airflow in my system.

Top card is always hotter

Yeah but I didn't expect it to be that much

That's pretty cool if you're mining... Mine is at 75C

Well just think about it. The top card is starved for air so there should be pretty big temp differences.

Nah lol, it's idle

and the top card also gets hotter air because of the bottom card

That depends whether it is a blower design or an open one.

either way actually. the pcb of the bottom card gets pretty darn hot no matter what card it is. that warms the air and then the top card will use the hotter air to cool itself.

How would this be? I mean I know hot air rises but inside a pc case there is not that much room anyway so air temp at top and bottom should be pretty similar right??

Looks like they are broken. Better send them to me so I can "repair" them

Because the intake of the top card has about 1-5 mm of clearance between the itself and the card in front of it.

Oh yeah okay, that makes sense, but if you had a fan on the side panel, would it help?? (Just curious to know)

It might help especially if it is a SP fan but the problem is it is hard to draw air in through the small opening between the cards but it would not straight up fix it. This looks like a job for water cooling!

Yeah tbh I wouldn't usually recommend watercooling your system, but this particular system seems like might take advantage of it. Still, I would find all the ways possible to get that top card cooler and if it doesn't work THEN I would consider water...

I don't really recommend it either. It is horribly cost inefficient but it is still awesome

Exactly what I think!
