Before anyone drops the bomb on these open case gpu's..... just like i almost did on two.
Ive seen more than one review stating that the cooling design is pretty flawed since the hot air doesn't get pushed outside the case but rather inside.

Comparing to the reference cards:
The CPU climbed a further 6c
The GPU Core rose 8c
The GPU PCB climbed 25c +
The ram climbed 9c
And other system components suffered as well due to the air being released inside the case.

SOURCE French translated

Although this card looks really sexy, im going to pass due to these facts.

maybe the case the reviewers used had ZERO airflow? I had a 5970 and an 8800 ultra on the same case with aftermarket coolers blowing hot air inside the case and it didn't affect my temps that much because I had decent airflow

Any case with decent airflow would counter act this effect...

Shouldn't have to rely on a case with "decent airflow" since the plain reference cooler is doing its job without "decent airflow" . The card is designed to run cooler and quieter...its doing the latter, but failing significantly on the former. Contradictory imo.

I still prefer the exhaust to the outside of the case cooler.
It's louder, but it doesn't bother me one bit.

I wouldnt bother with that flawed review. its the same as any GPU that dont exhaust rear of case.
Like the MSI Lightning, Gigabyte Windforce, Asus RoG, aftermarket cooling like the Arctic Cooling Extreme. All is the same.

So take that review and ignore it from that site, sure they have no idea how a PC and airflow worked.
Those are not even facts.

Yet Kitguru reviewed the same card and got lower GPU temps.

i saw this review and i saw other reviews from tweaktown, pc perspective and others. Most of them said it ran hotter. Plus you can't compare one review sights numbers to the other numbers unless the test bed and the testing methodology is identical.

You should still have good airflow regardless.
Very few enthusiasts systems have poor airflow.

some cards are known to suffer from thermal paste over use, please check your card for excessive thermal interface material before you RMA it.

tweaktown, pc perspective all show temps lower than reference for the GPu. Not sure where you're seeing this info of temps being higher.
My 5870 with Arctic Accelero is cooler by 20c. Yet I have 200mm fan cooling from the side. Not once did my ram, CPU temps ever got hotter due to that.

Like I said, that review is flawed, if he didnt have proper cooling.

All of these cards are the same as the XFX DD 7970, all heat goes inside case.

He is using a test bench, so not sure what the ambient temps is.

Plus its an OC version over stock reference, of course temps will be higher.
Please understand what your saying here.

If the review used a test bench, then unless they had a fan set up somewhere to draw away the hot air, then they would get higher temps than if they had tested in a case, where at least there should be exhaust fans above the cards exhausting either out the rear or the top of the case, even more so if they have a side intake where cool air can be fed directly to the cards.

If the card truly runs hotter than reference design, then its simply a design failure made by XFX in this case.

It is known that these axial fan designs (which dissipate heat into the case, not outside) are MUCH better in terms of GPU temperature and it has been proven often enough.., MSI Hawk Series, ASUS DCII Series, Gigabyte using the Accelero Extreme, Prolimatech MK-13 etc. most of them run up to 20°C cooler than the poor reference designs which may carry the heat out of the case immediately but simply fail to dissipate it quick enough as the radial fan designs dont achieve high airflow.

After all, it's obvious that you need good airflow if you plan on using a custom axial fan design... and lets be honest, EVERY enthusiast rig should have good cooling / airflow and if not, then you dont deserve either card

.

So either the test was made with a terrible setup providing no airflow or its simply a design failure made by XFX somewhere, but not the cooling technique itself...

i do understand, you need to understand that even though there is a slight overclock, it should still run cooler none the less.

Open case GPU's run cooler because the air is being dissipated off the VRAM quicker, result slightly higher ambient temp inside the case. Cooler GPU usually results in higher over clocks of GPU. May or may not effect CPU over clocks with properly ventilated tower.

Closed case shrouds where air exhaust is out the rear air flow bracket and across the VRAM end up with higher GPU temps, result lower ambient temps inside the case. Possibly higher CPU over clocks, if tower doesn't have good ventilation.

Nothing new here though. Always been this way. To each his own preference. It's not just this XFX card but any open case GPU. A bit misleading to just narrow it down to XFX.
