TDP/Heat/Cooling

post #1 of 4
Thread Starter 
Warning
This is not about the cards in this write up before any kind of bashing starts, this is to do with thermals.

Ok, i have a question, i have a PC with an old skool GTX 480 in it, and it is custom...

I have another PC with a Radeon 7770 1GB DD GHOST BE..

Both cards are clocked to their limits (temperature and voltage)

Ok, so in an ideal world, the GTX 480 should heat a room up faster than a 7770 right?


Well this is where it really becomes baffling.


The 480 (in a rig with a i5 2500k running 4.5ghz) is putting out less heat, and also running around the same temperature as the 7770 (thanks to custom cooling)

Now, many times i heard the saying, oh i bet you cook when gaming with the GTX 480, yada yada yada.....

But this is definitely not the case..


The AMD PC with the Phenom II at 4.0ghz and 7770 puts out way more heat, the whole case feels warm, and beleive me, it is well ventilated (Xigmatek Utguard, and Silverstone Raven RV02-BW for the intel one)


Now, this may not make sense to most here....

But TDP seems to not be what people think it is.

Sure, by all means a 480 is a hotter running card, but from my experience, only looking at a graph on screen, where as the AMD rig, you can feel the damn heat......


This is also not about the 480 or 7770, it is just something i wish to share, as i have those cards.




I am using these 2 cards, as they show a large difference in regards to actual heat out put into the room.

Hmmm...

Weird though, the cooler keeps the 7770 around 70-75c, as does the monster looking one i customized on the 480.


I was just trying to get a grasp of how a much lower TDP card can put out much more heat than that power sucking lard ass tongue.gif
