there's actually a single case fan in the front .. but still are u sure about it ? that i really need a better cooling system ? or is there something wrong with the card itself or maybe the psu ? .. i don't know .. i get good frames but the card's temp goes relatively high

this is an overclocked HD 7970. i don't know what you were expecting when you bought it. you can set a custom fan curse to make it quiet but then you risk damaging your graphic card.

i have a cooler master cosmos 1000 with no case fans and i don't have this problem with my cards

No, your PSU is fine. Nobody said that it wasn't. You need more case fans to take the load off the ones on the GPU. That way the fans won't have to run so fast to keep the card cool. I would get maybe two more 200mm case fans, that would probably solve the cooling issue.

by the way it becomes normal when i tweak the clock to 950 and vddc to 1000 .. is that ok ? or it is wrong that i tweaked the vddc from 1256 to 1000 when i underclocked it ?

i think it's all about the psu .. since my own psu powers up the card but gives only 28A on 12v+ .. so i think i might get me a bronze GX 650 cooler master that gives 52A on 12v+

look again, there's two 12V rails on your psu each giving 28amps!

theres nothing wrong with it. If the system doesnt freeze, shutdown or restart under load it is not the psu.

get more fans in there, if the temps are still high after that reseat the heatsink on the card or rma it. VaporX should be quite good cooler so those temps you are seeing are unusually high...

the thing is the card is always at 99% load when it is at 1070 clock and 1256 vddc , so the card gets relatively hot and the fan keeps goin up with it..

but now when downclock it to 950 mhz and 1000 vddc the gpu load doesn't even exceed the 40% load and temp is average at 55c .. so it becomes absolutely normal on that clock .. this is why i don't understand or get the idea .. if that's a problem in the card itself or i really need a bronze psu atleast

99% usage is normal under load when nothing else is bottlenecking or limiting the operation of the gpu (like too slow cpu or vsync etc...). In fact you want this.

40% load is a weird result from underclocking the card, it should not behave like that. Maybe the volts are too low... increase them a notch or two if you can, or just try every setting between the 1000 and stock but dont go over the stock vdcc...

edit have you tried running with the side panel removed, like in those pics? the temps should drop at least a little...

yeah, that's better :)
You could try and find a sweetspot for the clocks/temp/noise/performance if you like, because running underclocked like that isn't actually ideal since you've paid for the factory overclock in the first place.

exactly .. but still i don't know if the problem is with my card or cooling system .. i've tried to put a fan infront of my case to see if it's going to make a difference , the temp was around 72c on 1070 clock .. it reaches 80c easily if there my fan is not there

This is very typical of people who are still new to building higher end machines, never skimp on case fans and cable management once everything is setup. High end graphics cards dump a lot of heat especially with cards that draw over 200w full load so fan noise is part of the package. I'd take fan noise over random crashes any day. A few tweaks you can get that fan down to 60-70% but not much lower as you don't want the power vrm to overheat which on most cards is very common when neglected.

Overall you won't have to spend much and shouldn't take much time either to fix which is good. Cut the clocks on the core slightly and fix the fan at a constant 60% so it will be less noticeable than when it is constantly changing.

you really should get couple more case fans, from those pics it seems there are empty fan mounts available, one in the roof and one at the back at least.

Open air coolers push all the warm air back into the case so the case airflow needs to get rid of it, preferrably as soon as possible...

From those temperature numbers it sounds like theres nothing wrong with the card/cooler itself, the warm air just gets trapped in there so the cooler isn't getting enough fresh air.

ok guys since i've been making lots of tweaks and stuff .. i'm now stable on 1060 mhz , 1181 vddc , 66c and fan speed at 60% .. i don't really tweak the fan because it is made to cool the card so i don't really want to play with that .

but i have a question .. is it not wrong that i decreased the vddc from 1256 to 1181 ? .. because i'm pretty sure that the voltage usage was the problem causing all that heat , and also my psu has 2 rail 12v .. which is not actually good for gamers and its main disadvantage is not sharing anything .. but if i got a single rail with 50A+ .. i think that would fix the heating problem because if u notice .. my card goes relatively hot over 12v .. so maybe there's something unstable in the psu .. yes it is powering it up , but not in a good efficiency *correct me if i'm wrong*

so till now i'm going to stay on that setup mentioned above until i get new fan setup , but .. i need an answer ! is it ok if i leave the vddc like this ? will it burn my psu or card or anything ?

thanks to everyone though
