ATi Cards & Heat

Will the next generation of ATi cards run cooler than the 4000 series? I hope so because I like my card but the heat it puts out is insane (even with fan running high). I have had to underclock mine and every once and a while it still crashes my system from extreme temps (my case is set up well to deal with the heal but not well enough for this card). Other friends have told me similar stories so I'm not here to complain I just hope ATi does a better job of addressing the heat issue.
 
Heat and temperature are different concepts. It's most likely that they will consume more electrical power and thus produce more heat; this is the general trend in PC components.

If you're seeing very high temperatures on your 4850, it might be due to dust buildup, high ambient temps, or poor airflow. Functioning properly, temperature and heat output is not often a problem.
 
Dude something is up with your setup, that should not be happening at all. My friend has 2 in his case and they run a little hot but not too bad. and he's running a V1200 case with it's mediocre GPU cooling.

yeppers

look around the fan, and make sure the ducts that channel the air the fan is pushing are not blocked. had a 850xt and 1950Pro start throwing artifacts like mad, the 1st time (850xt) i thought was toast. i removed to inspect and saw no issues on the pcb, i then looked in the shroud that seals the heatsink, and a a half circle of dust had sealed the channels closed, preventing any air from moving thru. cleaned it and viola, no more artifacts.
 
HD 4770 uses 40nm GPU and runs very cool.

Since new HD 5000 series will use 40nm GPU I think they will be cool like the the HD4770.

Except the RV740 (4770) has a 137mm die size and the RV870 will be more than twice the size at 300+mm.

They keep shrinking stuff, but they also keep adding tons of new transistors.
 
Sounds awesome.

If new hd5000 series Is low voltage It may be cool.
 
If it uses less voltage it should be cooler than the 4000 series.

No, not necessarily. It will also have a lot more logic than RV770, and if the rumours are true, the die size even with the shrink to 40nm will still be considerably larger than RV770. For all we know, it's power requirements, heat output, and normal temperature range could all be much higher compared to the current 4000 series.

True on the unknown power requirements.

My statement is based solely on if the new HD5000 series is a low voltage card.


HD4770 reference card runs at about 1 volt.

Voltage is somewhat irrelevant. RV870 could run on 0.5V and still suck a ton of power. To use CPUs as an example, a Core i7 920 CPU runs at a lower stock voltage than a Core 2 Quad Q6600, but still consumes more power and has a TDP that is 35W higher.

Can't really say that.. the GPU is completely different. Just because it's manufactured on the same process doesn't mean it'll run at the similar temperatures.

I hope they run cool....
 
Having a cool card is not something that I want to see in a card. In my opinion, cards should run a little warm. If the gpu is cool, there is more overhead for making it faster.
 
Lol I have a 4870 and when I use my computer for a little while I will actually sweat while using it. I forgot to boost my fan speed a bit one time and my GPU was running 96º C.
 
Just a reminder, heat produced and temperature are two different things. For example, take 2 4850s under identical load. Card A has a temperature of 30C while card B has a temp of 99C. Despite the temperature differences, both cards are actually producing identical amounts of heat. Far too often people here look at the 4850 hitting 90C under load and think its pumping out heat like crazy, when in reality it really isn't.
