Lets see your HAF case builds people! Water air doesn't mater we want to see them all cause the case is awesome!

[TRIPTEX_CAN]

The HAF is getting tons of attention right now. I've had mine so long I'm almost over it now... almost but not quite. I still love this case and can easily say I'll have if for several years.

cant wait to post mine on monday.....Damn cypershot not being here........NICE rig triptex!

[Sasqui]

Work in progress:



Notice the Koolance plate on the top bay, it's a temp monitor display hooked up to an overheat shutdown control board



Hope I get to finish this thing soon, been working on it forever.

[ShadowFold]

HELL YES. Just got mine in the mail.. I worked up quite a sweat carrying it from my porch and up a flight of stairs I cannot wait to install everything.. Case is god damn HUGE

[theorw]

U have a porsche and not someone to carry it for u.......?LOL

[TRIPTEX_CAN]

Nice case Sasqui... where can I get an invisible motherboard?

[ghost28]

Mine......The HAF Rocks.......Tons of room, great cable management options, looks wicked, great build quality......

[BumbleBee]

we should get a members list, mods, cooling suggestion going. by the way you might want to ask a mod to move this thread to the club section. I think im going to rewrite my HAF analysis into a optimal cooling guide.

Sasqui did you change your expansion slot covers they look solid?

[ShadowFold]

So.. The stock fans don't move that much air, should I get a fan controller to make them move faster?

I think they move pretty good air. You have to remember that the air moving is over a much larger area so when you put your hand there it feel like less. In reality the total air moved over the 3 x 230mm fans is huge.. dont think of them as fans but think of them as walls of air.

[ShadowFold]

That makes sense. I still want them to sound loud A case just doesn't sound manly with no noise!

[TRIPTEX_CAN]

LOL alright then. I dont know if you can make them any faster. I believe they are already using 12v.

You could always add some fans internally to give it some kick.

[ShadowFold]

My 8800GTS is running hotter than any card I've ever had.. My old HD 2900XT Crossfire setup ran cooler than it It's at like 44-52c idle and gets up to 60-70c..

I think it's just the image quality, those are the stock mesh ones.

For mod advice, it took me quite a while to land on the configuration of the water pump and res locations. There's a whole bunch of reasons why I did it that way.

Great way to put it if you look at the bottom front fan on mine, you may notice the cut-out behind the mesh cover. That was the only flaw I saw... smaller holes there - restrictive for air volume across the HDD cage. So I took snips and fixed that

[Evo85]

Quite possibly the best case I have ever owned.

I didnt do much to mine. Painted the frame, and then a few minor mods.

The cooling of this case is excellent. Only down side is weekly dustings, but I can live with that.

[ShadowFold]

Yea I gotta agree, this is seriously the best case I've ever used. I even built a rig using an antec 1200 for a customer and it had ok cable management.. The haf has AMAZING cable management, I can stuff cables anywhere and there's a hole for it to come out at a good angle!

[HellasVagabond]

If i tell you guys something you promise to behave and not spread it around ?

[Evo85]

One thing I recommend is that if you use the bottom mounting for the PSU, go buy some furnace vent/register filters and place them under the PSU shelf. You would be surprised how much dust will get sucked up into the PSU if you dont.

for a video review of the Cooler Master HAF 932 see here.

Introduction

I think the Cooler Master HAF 932 (High Air Flow) is one of the best cases ever created with it's bold styling, features, cooling and price point. it has so many cooling options enough to fit everybody's needs, one thing nobody can argue is it has dethroned the Antec Gaming Series cases as "Air Flow Kings". the only feature missing in this case is a removable motherboard tray but if your like me and have been around for a long time it shouldn't bother you besides they are not as useful if you are setting up a liquid cooling system and Cooler Master did include a motherboard access hole. some people might have wished this case was aluminum like it's brother the Cooler Master ATCS 840 I should point out the disadvantages to a aluminum chassis and that is acoustics and durability, a aluminum chassis does not cool the hardware more efficiently than a steel chassis we are talking about a case not a heatsink.

Power Supply Mounts

The HAF 932 comes with two options to mount your power supply, the bottom mount and the top mount most people will elect the option to mount their power supply on the new standard bottom mount however is mounting the power supply up top better? lets analyze by mounting the power supply up top the power supply fan will intake cool air from outside through the top perforated vent and across the power supply heatsink then exhaust out the rear of the case the advantages to this is any hot air molecules that radiate up from the power supply housing will go up through the perforated vent and outside of the case and you will be, utilize the two bottom intake fans and having more space for dual slot video card or video cards. by mounting the power supply on the bottom the power supply fan will intake cool air from the expansion slots, perforated pci and side intake and across the power supply heatsink then exhaust out the rear or you can flip the power supply upside down and intake cool air from the bottom of the case where air is the coolest the problem is the hot air molecules that radiate up from the power supply housing will bind with the video card or video cards or even possibly sucked back into the power supply fan before they are exhausted and you will lose the advantage to mount the two bottom intake fans which are the most important. I recommend mounting the power supply up top.

Hard Drive Rack

Hard Drive cooling is very overlooked a standard hard drive has a maximum thermal operating temperature of 50'c-60'c before probability of failure and as you can see hard drives can get hot this is a thermal image of a Seagate hard drive in a Cooler Master 690 Hard Drive Rack which is very similar to the HAF 932 Hard Drive Rack. if you look at the rack you will notice several sets of rectangular holes on the front and back for ventilation between each rectangular hole is where a hard drive bracket gets mounted so no real air from the front fan really makes any contact with the hard drive it rather blows the radiated heat away and if you put your hand on the back of the hard drive rack you will not feel any air this is because the front fan has to pass through a sheet of metal, a piece of plastic, a hard drive, another piece of plastic and another sheet of metal this is not only restricting air flow but could also create the possibility of a hot pocket of air forming this is why it is a cause for concern (see Modifications section) there are 2 reasons why some case manufactures are mounting the hard drive racks 90' or on the side 1) no clearance issues and 2) a hard drive is hotter on it's sides than the top or bottom.

Positive vs. Negative Air Pressure

The HAF 932 offers you the option to setup positive or negative air pressure. for more information see here. in a nutshell negative air pressure is having more air exhausted from the case by a vacuum the advantage is not having hot pockets of air the disadvantage is the accumulation of dust. positive air pressure is having more air intake into the case the advantage is direct cooling and the disadvantage is having hot pockets of air. which is better? I recommend positive air pressure because with negative air pressure to combat the accumulation of dust you will need filters and filters impede air flow (see Fan Filters section) positive air pressure will accumulate less dust and offers better cooling because nothing can compare to four side fans directly cooling onto the motherboard.

230mm Fans

The HAF 932 comes with 3x Cooler Master 230mm fans their specs are 700 RPM (revolutions per minute) 75 CFM (cubic feet per meter) 19 dBA (decibels) i'm not sure if these specs are true because a lot of companies for example Thermaltake like to exaggerate so lets assume for a moment they are true the first thing I would like to point out is these 230mm fans have low static pressure which means they cannot maintain their 75 CFM at higher resistances normally this isn't a concern for case fans but because of the size and cooling options of the HAF 932 this cannot be ignored these fans just cannot outperform a 120mm at this time because of cost and production, companies like Delta and Sanyo Denki make 120mm models that can outperform them but at the cost of noise this means any three quality 120mm fans can exhaust more air collectively than the single 230mm fan in the top the only benefit the 230mm fan has is silence and I would say aerial coverage because of the diameter of the fan but with the low static pressure it doesn't even have that lets take a look at the side panel in this picture you can see that Cooler Master chose to put the 230mm fan mount in the middle of the four 120mm fan mounts so by mounting four 120mm fans it will not only push more air collectively but offer even more aerial coverage however this comes at the cost of noise I highly recommend removing all three 230mm fans for replacements if you have a big budget I recommend six or more Scythe S-Flex G and undervolting them with a fan controller (see Fan Controllers section), for a low budget I recommend six or more Yate Loon High Speed and undervolting them.

Tip: head over to Jab-Tech you can purchase ten Yate Loon D12SH-12 High Speed for $39.26 USD including shipping. Yate Loons are excellent case fans and great radiator fans they perform on par with the Scythe S-Flex Series for a fraction of the cost.

Fan Filters

dust is an insulator it can even cause shorts. fan filters are becoming more and more popular these days the HAF 932 doesn't come with any however for the last 20 years PC experts have been using a can of compressed air on there monthly maintenance so make sure you purchase a can and be sure it's chemical free hold it a foot away from component on an angle and use short bursts. I don't recommend a house hold vacuum cleaner as it is unsafe compared to a electronic vacuum cleaner. Vapor at XtremeSystems did a analysis on the effects of air flow using fan filters and his findings were some filters can be as restrictive as radiators and you will never be 100% dust free with filters the only way that is going to happen is if your computer is in a cleanroom.

Fan Controllers

The HAF 932 has 11 fan mounts. if your going to be using a lot of the fan mounts I recommend a fan controller with high wattage like the Sunbeam Rheobus Extreme or Lamptron FC-2 if your not using a lot of them or you are setting up a liquid cooling system I recommend a Sunbeam Rheobus or Zalman ZM-MFC1 Plus. all four of these fan controllers have excellent build quality.

Warning: the NZXT Sentry LX fan controller has only 4 watts per channel and cannot control the stock 230mm fans.

High Air Flow Examples

setup #1 power supply top mount no liquid cooling

* 1x Front Intake 120mm x 25mm at 7v
* 2x Bottom Intake 120mm x 25mm at 7v
* 4x Side Intake 120mm x 25mm at 5v
* 1x Rear Exhaust 120mm x 25mm at 12v
* 1x Top Intake 120mm x 25mm at 7v

setup #2 power supply bottom mount no liquid cooling

* 1x Front Intake 120mm x 25mm at 7v
* 1x Bottom Intake 120mm x 25mm at 7v (optional depending on power supply length)
* 4x Side Intake 120mm x 25mm at 5v
* 1x Rear Exhaust 120mm x 25mm at 12v
* 3x Top Intake 120mm x 25mm at 5v

Radiator Placement

The HAF 932 comes with multiple stock radiator mounts you can mount a 120mm x 240mm on the bottom, two 120mm x 240mm on the side, a 120mm x 120mm on the rear and a 120mm x 360mm on the top.

Warning: the Thermochill PA 120.3 and 120.2 radiators are incompatible with the bottom, side and top radiator mounts because Thermochill uses different fan spacing, you will need to drill new holes.

Tip: if you have a 120mm x 360mm mounted on the top I recommend removing the top power supply plate that holds the 2x liquid cooling tube grommets for extra ventilation regardless if your fans are in a push or pull configuration on the radiator.

Modifications

1. I recommend you remove the perforated mesh on the expansion slot covers these will restrict air flow and you may find yourself cleaning them one too many times this will shed a couple degrees off your video card and if you elected to mount your power supply on the new standard bottom exhaust the heat radiated up from the housing, if your unsatisfied with a gaping hole for a expansion slot you can always purchase a pack of Silverstone Aero Slots you get 4 nickel plated expansion slot covers in a pack and you can find them at several online computer retailers for $4-8 USD.
2. for a beginner's guide to cable sleeving see here, for a advanced guide see here.
3. to change the power and hard drive activity LED's on the front panel see here.
4. removing the hard drive rack and turning it 90' to face the front of the case is becoming more and more popular this can be done by using a drill to pop several rivets out and to re-seat it use a rivet gun with 1/8" rivets, some people have even removed the hard drive rack all together for extra space and air flow and used a 5.25" to 3.25" hard drive adapter in the 5.25" Bay or Cooler Master 4:3 Module (used in the Cooler Master Centurion 590, Cooler Master Cosmos S and Cooler Master Stacker 83x) to mount their hard drive or hard drives in the 5.25" Bay you can also take the front filter off the Cooler Master 4:3 Module so you can keep the HAF 932 drive bay covers on.

@Bumblebee... Never heard anything negative about the expansion slot covers before... they seem to have quite a bit of open area by themselves.

And yes, dust filters are out of the question for this case, unless you want to wrap the whole thing in tyvek, LOL. IMO, dust filters aren't worth shit anyways.

[BumbleBee]

the perforated mesh covers are going to restrict air flow because the air has to pass through an object by how much who knows 10%, 20% but they will restrict vs an open hole. the perforated holes are also kinda small so dust will build up and restrict of course this will probably take a while to happen and will probably never happen if you do general maintenance. i'm happy Cooler Master elected perforated mesh as covers I just wished they would of used the Storm Sniper's covers instead.

[HellasVagabond]

The case is great as it is and the airflow is excellent so i suggest you leave it that way, unless you want to place 120mm fans and make it a lot noisier or remove the mesh covers/filters and collect dust every day.

I disagree, thats why I wrote the guide in the guide when I mentioned Delta's and Sanyo Denki's I didn't mean go out and buy seven of them you can use any case fan I like Yate Loons they are quiet, undervolt well and inexpensive also Cooler Master 230mm Fans are not exactly easy to replace. i'm not sure I understand when you say removing the perforated mesh covers will actually create more dust?

[Evo85]

I agree with Hellas. If you need more air cooling then what is stock, you would be better off with water.
