erm..the casing is coolermaster cm690

http://www.coolermaster.com/products/produ...cate=17&id=2908

and the fan's slot is like this
Front :120 mm Blue LED fan x 1, 1200 rpm, 21 dBA,(intake/exhaust?)
Rear : 120 mm standard fan, 1200 rpm, 21 dBA,(intake/exhaust?)
Top : 120 or 140 mm fan x 2 (intake/exhaust?),
Bottom : 120 mm fan x 1 (intake/exhaust?),
Left: 120mm fan x 2 (intake/exhaust?)
erm..i eman...which slot shld i use for intake...and which fr exhaust....

erm...what and which type or fan shld i use?and...if i use the fan u suggested...which PSU...shld i use?

PSU requirements depends on ur hardware...not fans

as long as you're not using those industry grade, powerful delta fans, any psu should be ok

take 12volt x ampere = watt. calculate this way, u'll know total power consumption of your fans

no need to worry bout fans, im having 8 CM 120mm fans plus a 70mm cheapo fan and its not a problem, only using cm extreme 460watts.

Added on March 8, 2008, 8:35 pmwell u could try:
Front :120 mm Blue LED fan x 1, 1200 rpm, 21 dBA,(intake)
Rear : 120 mm standard fan, 1200 rpm, 21 dBA,(exhaust)
Top : 120 or 140 mm fan x 2 (exhaust) is a must, it helps a lot
Bottom : 120 mm fan x 1 (intake)
Left: 120mm fan x 2 (intake/exhaust) oh, ur using the cm stock side panel, mine got window so only 1 slot (try intake, helps in GC n NB, SB cooling)
better filter all intakes, or it'll be horrible in a week inside.
Extra suggestions: if u got only 3 slots free at the cd bay, screw an intake there. Yours should be top io panel right?
Hope it helps.

1st pic, see the 3 lines, that is sponge taken from old cm casing

2nd pic, how i put, i put in between fan n panel, too dark hard to c

wooo bo so many fans??? too many can be overkill and just not effective...1 x 120 to blow in and 1 80 to suck out qhile 1 blow hd should be sufficient...I think??

erm . . . i dont think so, i think. Well all the back n top are exhaust while the side, bottom and front is intake so i guess the flow is just fine, hopefully , no way to try and c airflow turbulance

Thr r forumers even got 8 fans so not a big surprise. However if u r too worried bout power consumption use the formula uglyvamp posted 2 calculate watt

Since u didnt post specs of da fans cant help calculate 4 u

just want to "tumpang" this topic, also about FAN & Power Supply

this is my screenshoots, just want to know about my Voltages Reading



is it my Voltages ok,
my pc spec is

PSU - Power Logic Magnum 300
Fan : 2x80mm LED + 1x120mm LED
CPU - E2140 O.C at 2800mhz (350x8) at default vcore + stock HSF
Mobo - GA-P35-DS3
RAM - 2x1GB DDR2 667 O.C at 840Mhz (420x2.4)
GPU - Asus 8400GS
PCI Card - PixelView TV Card + VStream Captured Card
HDD - 160GB SATAII x 1

7 fans should be no problem on any psu.. most important is the hardware you use.. im using 7 fans also (including psu fan)... 6 fans in the casing and another one on the modem because my modem too hot which on for 24/7..

erm..but....im just scare..if there's not enuff cable?like molex..or motherboard 3 pin or 4pin..im just scare about not enuff socket...

normal the fans package will give u 3pin to 4pin converter and 4pin expand +1

i m using 7fans now still got many 4pin available use

I also wana tumpang...i am wondering why some fan come with just the 3 pins and some come with this molex thingy?molex are so big and i dun like it man...cable managment hard..

1 more i wana ask...if i use those powerful delta 120mm fan that is around 5400RPM...a 3pin will be ok?or need some kind of special cable?thanks

If it comes with 3 pin means 3 pin is enough to supply the power to the fans.

PSU is just supply the power. u can put as many fan as u can in the casing =)the power using oso less only;p

why do ya keep salvage old thread which already got answer?

He seems to be surfing around digging old threads, weird.

additional hardware like fans just used 50W dun wory la bro
