Case to cool a GTX590

post #1 of 10
Thread Starter 
Ponycar:

Further to your PM, I suggest Cooler Master HAF 932. My analysis is below:-

Card consideration
Pics 1 and 2 show the heatsink airflow design of a GTX590. As you have already noted, it emits hot air from its front and its rear. Obviously the major concern is that 50% heat dump emitting out from the card's front.
IMHO, the cooling of this type of card requires two aspects:-

(1) A clear and distinct path for this hot exhaust air to escape out of the case
--as soon as possible
--as directly as possible (ie making air path directional changes as small as possible)
--affecting other PC components as least as possible (going through the CPU cooler -air or water cooled radiator- must be avoided).

(2) A clear and distinct path to supply fresh air to the intake fan of the card

(1) and (2) must also not cross-path with each other. A mixture will just reduce the efficiency. The higher the mixture, the less effective is the method.

Chassis consideration
I have advised several members here to use a 'top exhaust' approach to achieve both (1) and (2) simultaneously.
I still recommend this approach to you as I reckon it serves your situation well. Simply put, the chassis for this approach should have:-

(1) At least two (preferably three) fans on the case top for exhaust. They will be responsible to extract all hot air (from the graphics card(s) and the CPU). The reason of having at least 2 fans is to spread the fans across the entire top of the case so that hot exhausted air from graphics card can be drafted upward in a more direct route, making it less likely be sucked by the CPU cooler fan.
(Note: if you use the stock Intel fan which is down blowing, it is still OK. But it will be better if you use an aftermarket cooler and orient it blowing upward)

(2) At least two (preferably more) fans on the side panel to supply fresh ambient air to the graphics card. Supply from the case front should not be relied on as the airflow from that direction will run against the hot air uprising to the case top. These fans will also be responsible for supplying fresh air to the CPU air cooler.

There are a few cases that can meet these criteria. And as I have personal experience with the Cooler Master HAF 932, I would suggest it to you. See pic 3 below for an illustration.
Examples:
A) HD5970 inside a HAF932 (read posts #16 and #28) – this one is very similar to your situation.
http://www.overclock.net/air-cooling...w-chassis.html

B) GTX580 Twin Frozr II SLI inside a HAF932 (note post #12)
http://www.overclock.net/computer-ca...ii-best-2.html

C) Asus GTX570 DirectCU II inside a CM 690 II Advanced (note post #15)
http://www.overclock.net/computer-ca...eed-fan-2.html

PS
a) Do not use the type of cases (eg Silverstone RV and FT series) that orients the motherboard vertically as this will lead to a string of thermal complications.
b) That 5% heat dump coming out of the card's rear top is small enough and will be easily extracted out of the case by the rear exhausting fan of the 932.

Use this post as a starter. If you have further question, we can continue the discussion here in this thread.

Thank you for your valued input and I appreciate your work Windfire.

What is your feeling on a reverse atx case that puts the video card near the top exhaust fans such as this:

As the graphics card is a GTX590, the 2 considerations of the card still apply. And so, a chassis must still be able to provide (1) and (2) in order to cool the GTX590 well.

I have not seen the the MountainMods Monticle 24 in real life action before but I will still examine it on a theoretical level. See pic below. There are a few attentions:-

1) Space behind the case must be ample so that hot air exhausted into that region can be dispersed quickly and this will reduce the chance of hot air recirculated into the case

2) Card's front hot exhaust better be extracted by an exhaust fan positioned in the case front 5.25'' bays. Perhaps using one 92mm fans occupying two of three bays is good enough. And this leaves one bay for an optical drive.

3) The 2 top case fans near the front should not be used as exhaust as they are in proximity to the other 2 top case intake fans.

So, I reckon this R-ATX chassis should be able to handle a GTX590.

So basically, I shouldn't get the RV03 because I have a twin frozr?

I tried to PM you but I think it's not available to send you private messages so I had to ask my question here at this post, pardon me if I'm doing something that I shouldn't.

I got a Zotac Gtx580 and I will get an Accelero Xtreme Plus II VGA cooler thus I need a new case as my old one doesn't provide enough space for my future VGA cooler.

I have a $200 budget for case and I'm thinking of getting a CM Haf-X. You really sound like a pro at this so I couldn't help myself asking for your advice. Would you suggest me to get Haf-X to get the most of both my VGA and my future VGA cooler?

BTW, I have a Noctua NH-D14 with 2x fan configuration, one on the right and one in the middle blowing like this: I<I<
Feel free to LOL @ my poor schematics ^ here

So what you suggest I get and whit which fan configuration should I use it? (Like 4x 12cm side fans or 1x 20cm side fan etc...)

I might forget the check here so I'd be so damn glad if you could send your answer to my e-mail adress: efecanirim@gmail.com

Thanks beforehandly.

I do not think my PM box is disabled. I do not know why and I will check.

HAF-X will excel if the card(s) uses 'traditional' cooling of 'front-centrifugal-fan-intake-and-rear-slots-exhaust'.
However, IMHO, HAF 932 will do a better job when dealing with aftermarket coolers like AXP II.

My observations:-
AXP II exhausts air out omni-directionally (ie not just in the direction of card's front). This makes it harder to be managed well. See pic below.

Fresh air supply consideration: (the 3 green arrows are the intakes)
1. From case front: slow spinning large diameter fan is a source but probably should not be the major one because it is too far away and the incoming air does not move with a high enough speed to reach the 3 intake fans of AXP II.

2. From case bottom: this might be the best source. A strong 120/140mm fan is preferred.

3. From side panel fans: this direction must be carefully done because it might run against the side exhausting air along the length of the card. Therefore, the 2 lower fan positions of the 932's side panel might be more beneficial than one large 200mm fan.

Exhaust consideration: (see the red arrows)
1. those hot exhaust nearer to the case rear will be extracted by the case's rear exhaust fan

2. those hot exhaust in the middle portion will likely go through the CPU cooler (NH-D14) unfortunately. This will have a negative effect obviously. Hopefully the impact is limited. And this is one trade-off that one has to accept when using this type of graphics card cooler. To minimize this, see below.

3. those hot exhaust in the front will be drafted upward.
3.1 932's three 120mm fans should provide more an upward draft than HAFX's two 200mm fans

3.2 as NH-D14 is such a large cooler, I am not sure if you can set it up oriented vertically. So, with it being in the more common horizontal blowing orientation, you will have to setup an air duct running from the front 5.25'' bays to the push fan of the NH-D14 in order to avoid the card's hot air being sucked by the NH-D14.
When such an air duct is in place, perhaps consider using the two upper fan positions of the 932 side panel to extract the hot exhaust from the card as well. If so, then the 2 lower fan positions should not be used to avoid 'proximity recirculation'. Then, the case bottom intake fan will be the chief source to supply fresh air upward to the 3 intake fans of AXP II.

Summary
HAF 932 offers more flexibility (in fan positions in the case top and the side panel) to handle your AXP II cooled GTX580.

Summary
HAF 932 offers more flexibility (in fan positions in the case top and the side panel) to handle your AXP II cooled GTX580.
Uhmm. I never thought the position of fans would affect the cooling performance of aftermarket heatsinks, your explanation has been eye opening for me.

So you suggest I get a 932 instead of a Haf-x? But as far as I know, 932 doesn't have an air duct... But Haf-x does. And the heatsink on the picture that you've attached is not a nh-d14, probably some other single tower heatsink. Noctua nh-d14 has double towers so its larger that that.

Here is a photo showing the specifications of a Haf-x case, showing the air duct and all.

As for the hot air blown from AXP II sucked by cpu fans, I don't think such thing will happen as the GTX580 is the same lenght as the AXP II. I mean, the hot air will be ventilated out by the air blown by front fan, thanks to the air duct of Haf-x
Here is a photo of the combination. Even if such thing happened, Haf-x case has an air duct to prevent the hot air blown from AXP II to be sucked by cpu intake fans, I presume.

These are my thoughts, please correct me if I'm wrong.

I am aware of the air duct but it is a non issue regarding the 932 vs HAF-X because:-

(1) HAF 932 Black Edition also has the same/similar air duct. So, the higher flexibility of the 932 over the HAF-X remains.

(2) Actually, I did give consideration to the effectiveness of the air duct, hoping its deployment might lower the advantage of a 932 over an X.
However, I still do not think the air duct (whether using it in a 932 or in an X) would provide much cooling benefit, if at all. I might even incline to think it would harm the cooling. See pic 1 below.

2.1 The duct will enclose the about 1/3 of the card's PCB length. As the AXP II is longer than the PCB, a large portion of it will be inside the duct. Most importantly, the front portion (ie its length above the front intake fan) will be enclosed, making the upward exhausting air very difficult to escape (ie the smaller orange circle). And they will likely be recirculated by the intake fan. Not a desirable outcome.

2.2 for hot exhausting air nearer to the other end (ie the larger orange circle), they will likely to go upward. If they go downward for one reason or another, they will be sucked back by the 2 intake fans of the AXP II. This is non desirable (the black X). As they go upward, they will affect the NH-D14 more or less.

I am also aware that the heatsink shown in my previous pic is not a NH-D14. I am just using it as an example as I see the length of NH-D14 does not affect much in the designed path of escape airflow for the AXP II.

Actually, when you decide to use either case, you can try the air duct with and without and compare the thermal numbers. I will bet my money on 'without air duct' would bring lower thermal numbers.
