purpose of this bracket?

[frozensun]

Okay guys,I mean I can understand if any company made this too cool some device,but I don't really see a purpose of this bracket.

Behind it is a HDD who ofc heats a lot so puting fan here will blow the hot air towards GPU,right?

So I really don't see any benefit of installing the fan onto this bracket (marked with red arrow).

Do you?

I have one HDD behind it.

I could lower the HDD to bottom cage and the one on top will be free.

So the intake fan will blow fresh air onto this bracket and this one towards GPU.

But I'm not really sure if any benefit from it,while blowing air into the GPU.

Anyway I will install the fan and try to move one HDD to the bottom of the cage.

It definitely seems like a weird GPU cooler fan... Not quite sure why it would be mounted there of all places but it's definitely for an extra fan on the GPU. Doesn't quite make sense though...

[frozensun]

So installing the fan here is useless?

[Spotty]

It's a bracket for a fan.

Its not a GPU fan, its a HDD fan. Mounting there would blow over the HDD bays to the right.

its a mount for cooling the GPU

Either way,my thought is that is useless,how can something inside the case blow "fresh" air to ANYTHING!!

Dumb thing.

It pulls air through the hard drive area. It's not pointless.

the only way to find out if its pointless or not is to do a GPU stress test. look at the temp
then install a fan there
new GPU stress test. -> look at temps again

(you need to look at room temp for each run) 
This is the only way to know

GPUs have their own HSFs built right onto them, they don't need additional fans and actually, having a fan in that position could end up hurting the GPU.

 

That position is designed to pull cool air over the HDDs and blow it back into the case for the GPU to reuse.

Hurting the GPU? I would like to see that lol

"blow it back into the case for the GPU to reuse" ??? 
its almost like u dont understand the airflow pattern in a pc case 

[frozensun]

I think NZXT didn't count that in the future the GPU will be bigger and bigger and weight 3 kg...
This was meant for small graphics cards like for SSF

But after all this case is old...so I could forget that to NZXT...

Someone sound the personal incredulity alarm.

 

If the GPU is pulling air from inside the case and blowing it out of the IO bracket then you go and stick a fan in that exact spot that's pushing all the air out into the HDD bay you're going to starve the GPU of air and cause it to overheat.

And neither do you considering the airflow pattern is entirely based on how the user mounts the fans.

 

If you're struggling to understand how reused air can still cool something then I'll ask a simple question, how do you think PSU's mounted with the intakes pointing towards the inside the case work? Its simple thermodynamics, as long as the ambient temp of the air being used is lower than the temp of the component you're trying to cool energy exchange will happen and heat always tries to equalize from hot to cold where it can.

 

It makes zero sense to blow hot air from the GPUs onto the relatively cool HDDs, it makes total sense to blow the relatively cool air from the HDDs onto the hot GPU.

just to remove all the confusion. or lack of understanding

That is nonsense. Fresh air stops on those hdd:s and if you add a fan, it moves it under the gpu. Without it you will create much more easily a loop for your gpu where it just recirculates its own air when the fresh low pressure air coming in from front behind the hdd-area gets sucked out by exhaust fans.

The fact you think hot air somehow escapes through the PCB and backplate tells me everything I need to know.

 

I'm not going to continue this discussion since I don't see it ending well.

thats right, u don't need to continue this. u have embarrassed urself enough.
Hot air do get exhaust here and towards the front, back AND towards the MB(PCIE socket) 

[frozensun]

@NorKris is right,I could feel the hot air on my elbow at the places marked with red.

[For Science!]

Just speaking to myself at this point, but technically a fan doesn't push air very straight by default. As you know the center of a fan houses the hub, which does not rotate, and therefore doesn't produce any airflow. The air spun around by blades want to escape radially, but are somewhat forced into a cone in the direction of the blades by the shroud.

 

At the end of the day, the objective of PC cooling is to remove hot air from inside the chassis to the outside, so any airflow that pushes the air around towards the exhaust is helpful. Even if it means just mixing the internal air of the case to minimize hot pockets.

 

An simple analogy would be whether you think that a pot of soup would cool faster if you kept it still, or whether there was a stirrer bar inside constantly mixing it.

As has been stated, its a fan mount to help with airflow through the HDD cage when its fully populated with HDDs, it also aids in directing airflow into the GPU.

 

I actually bought this case years back, alas i never used it and had i sent back, i went through 5 .. yes 5 of these in White, all of them had issues with the paint chipping of the side panel during removal and installation. I really liked the look of the case, clean.

 

If u remove the HDD cage u dont really need to use the internal fan mount. but if u intend to populate the cage it will be helpful.

[frozensun]

So judging by exhaust air from the GPU,my side case fan should be oriented as exhaust, too?

It's oriented as intake by default.

Only the bottom cage can be removed,top one is fixed...but there is no purpose of removing buttom cage because it's almost under front facing fan.

I cant remember, but ..cant u rotate the HDD cage so it 'open' ? ..i honestly cant recall if that case has that feature or not.

Btw off-topic:

U notice anything unusual around graphics card?
