Should be intake for bottom, and may be add one more fan at 5.25'' bay?
Too must exhaust fan will create low pressure on your casing, which dust will enter your casing where didnt covered by dust filter.

yea, i also think to add 1mo at front panel, what to do if i use all the fan connector on mobo?

Use splitter or fan controller.

This one is splitter or Y-adapter.

OR directly connect to PSU:

cant control the fan if use this, unless you mod the splitter.

how much is the selling price of splitter or Y-adapter? directly connect to psu must b very loud? i guess the 1st method is better.

i decided to put 1mo fan at front panel, bottom i put exhaust, ok rite?

The splitter is very cheap, cheaper than a fan controller that is
Directly connect to PSU not loud, the fan will run at Maximum rated power. yeah its loud, any fan speed higher than 1200rpm mean loud for me
If i recall it correctly, Asus mobo can control the fan speed for each fan header, while Gigabyte only one, CPU fan header

IF the fans total ampere too high(most mobo only support 1A, MSi support up to 3A iirc.) for your mobo you will need to use the method below:
You can mod the splitter, Black wire connect to PSU, Red and Yellow connect to MOBO fan header.
all you need is just something sharp like needle or knife to push the clip from the connector(the silver thingy), press the silver clip and pull the wire slowly, dont use force else the clip will be left inside.

Yeah you could try various configuration and see if its suits you. remember too much exhaust fan and if they are running at full speed, dust will enter your casing very easily.

Does case fan consume lot power from psu?

Depend on the fans rated Ampere, most fan maker will put the info on the fan's sticker.
Most cheap pc fan usually are 0.1A to 0.3A, server fan will eat alot power, 1A to 3A and may be higher.

You can calculate the power yourself, eg 1A 12VDC fan = 12Watt.

Hi, i just upgrade my cm hyper 212+ plus fans recently to dual Arctic Cooling F12 PWM fans for push pull config, and extra 2 fans for my case, im also apply new arctic cooling mx-4 at the same time, but not much improvement for my rig temp. B4 my cm hyper 212+ single blademaster is around 90c while oc, but after add those fans the temp still same around 90c, is there anything wrong? My case is front 2x120mm intake, bottom 1x120mm intake, top 1x170mm exhaust, rear 1x120mm rear exhaust, total 5 case fans.

I think there's nothing wrong. I do experience the same situation. I replaced the pwm fan which come with my deepcool ice blade pro with CM excalibur and it still show about the same temps. I think this is more related to room temps which can influence the temps of your rig.

glad i found this thread....im currently trying to learn about airflow in PC cases, and at the same time, lowering the temp in my rig...i used a CM Elite 360 casing which has 2x120mm fan slot (top and on CPU), and 3x80mm fan slot (2 exhaust at the back and one bottom)...there is also a free hole on top of the GC port...in my case, the only cooler that fit my case is CM GeminiiS, which im currently using, but this particular CPU cooler makes the air blow into the CPU and also to some mobo components, making heats dissipate through the sides...so currently my configuration is 2 intake fans for the CPU port and the bottom, while for the back exhaust and top are all exhaust fans...so now if anyone can advice me on this configuration or change it for better, it would be much appreciated...and also, suggestions for exccellent 80mm and 120mm fans...

Do u think its bad air flow? coz 3 intake 2 exhaust, and 1 of the exhaust is 170mm, so the rpm is slow, means 1 of the exhaust process is slow.

I assume you position your casing vertically. If that's the case then the setup is fine IMHO, just need to tidy up the cables if it's messy to improve airflow. as for fans you could try noctua for 120mm although it's quite expensive. arctic cooling fans also quite good or if you don't mind the sound of air blowing out from your case there's coolermaster turbine master & coolermaster excalibur.

general rule is the bigger the fan the more air it can suck with slower speed.
to me the airflow is not bad. you could try to experiment which were best. maybe you could try to remove the bottom fan so there'll be 2 intake and 2 exhaust and perhaps can seal the bottom of the case with selotape so that air cannot escape through that and went to the cpu cooler instead.

thx for the tips , try seal bottom later, will update later.

This is how i seal my case bottom , with bended A4 paper.

The cpu temp is 1c decrease, but my gpu temp rise about 4c

4c increase, wow that's a lot. not worth that 1c decrease in cpu temp.
can try to use only 1 fan at the cpu cooler and put the other one at the back.
as for the bottom try several setup, with fans, no fans, bottom seal etc.
basically trial and error until got the temps you desired.

yea, will try several setup when i free

Want to check with you guys with regards to the silverstone fan especially silverstone sifus here. I have recently purchased FM123 fan and i found out that the fan must be connected to the fan controller in order for it to work. And along the line I found out that the model FM181 does provide a full speed connector (left) which seems compatible to my fan.



Thus judging from the appearance of the connector, it looks as if it functions like a jumper. So my question here does a hard disk drive jumper works in this case? I wanted to try but I feared it would do harm than good hence I need an advise here. Thanks.

Anyone seen Evercool FOX-2 being sold anywhere at LowYat?

haha, i did tht to my usp 100 too! my floor is so dirty,

izit possible for me i blow out the air from the bottom part instead of blowing into the casing?

any idea where can get the 12x12 dust filter? hardware shop?

I think you should buy a small table to put your rig so that you can put the bottom fan to blow air into the casing

Here, ask him whether he still got the filter or not
filter

i see, looking for the cheapest way.

does the filter will affect the air flow?
