Why do you want to look for big big fans?

Want to turn you're pc to be a vacuum cleaner?

u can always use a fan filter.

normally ppl choose big fans because of low noise and high cfm.

yes... mod.. u should sticky this topic...
and put the casing fan that recomemed by us..

example
80mm casing fan
--------------------
XXXX - RPM - XX CFM XX dBa XX speed

90mm casing fan
-------------------

like tat.. i can promise tat... a lot of people will go to look at this thread...

just my suggestion hehe
haha

hehe finally can do something for this thread

120mm Fan Roundup: 17 Fans Compared

1 ultra big fan is enough,,.. no need many small fans...
also, can be a hair-drier, lolz

I saw it at Lowyat few days befire... at All IT Hypermall

Spec:
Overall Dimension: 140 x 140 x 40 mm
Rated Voltage : 12 VDC
Bearing Type : Ever Lubricate bearing type (Long life bearing)
Life Time: Over 40000 hr
Speed : 1200±10% RPM
Noise : <22 dBA

No CFM provided....
14CM fan

yeah saw that too....the cfm should be around 40+ with 30- db
not bad bt evercools best..... or if u can get the yate loons are the best, very silent yet got the cfms..... anyway if u wan best noise to cfm ration best bet is the panaflow series, 120mm, i personallaly own one and bvery happy with it, bt after a while the fans have a small clickking nloise that u can mistakenly think its ur hdd... neway this happens only when u undervolt or over volt. overvolting will make the fan very fast bt only slightly noisier bt will die within a few days, killed my 3 panaflows thuis way on my tripple rad...

Be careful when handling case fans. Last night I open up my casing just wanted to push a wire aside, I got cut by my Nidec 92mm TA350DC fan... the speed was set to 3000rpm.. gosh.. lucky just kena my knuckle. But I can see some flesh off my skin right now.. *ouch*

i've saw my friend's fingers flesh almost ripped off from a FFB delta. the mighty 190cfm fan taught him to use fan grills and never work when the fan is operating

hey guys.... u make me scared, lol

Lets discuss a topic here...

I dunno if you guys have ever tested this. Try to get your fan to fun faster (higher rpm) and see whether the temperature of ur cpu drops? Cos what I did was, I set to a high n low settings... all I got the difference was a 1°C


Secondly... I dunno how many people notice this but the speed of your intake (masuk) and exhaust (keluar) makes a big difference. But this is odd, my case worked effectively in reverse. They say that your intake should have a higher air flow (cfm) and higher speed (rpm) than your exhuast, but mine is that my exhaust is faster and better air flow than my intake and my case is cooled about 4°C better than the 'recommended' sequence... anyone knows why? Is it because we should always suck the hot air out more than bring new cool air in?

recently... my pc temp was 47c.... i added 2 fans (intake) in random place....
good thing is i've manage to drop down to 35c...
*the fan i was using is taken from cap-ayam psu...

Basically with a nice heat sink ..whether u turn to high or low RPM it may not make so much of difference .... unless the heat sink is really weak in dissipate heats.

personally i prefer to have higher rpm for exhaust as it could take out the heat accumulated at the CPU area while the intake should be just enough for cooling off the HDD....

its what you've mentioned. hot air is removed and prevented from recirculating the whole interior of the case.

lets put it this way. by exerting more air into the case, you're creating a compression. to do this you will need powerful pressure fans or better else a air compressor. the output is still not tally with the input thus the hot air is still trapped inside. in addition, your fan might not operate at a high efficiency as the interior has a slight higher pressure as your fan is trying hard to push air in. if your work the other way round, creating a vacuum means more hot air will be removed. the addition of the vacuum in the interior means more atmospheric pressure is forces naturally in to the case. thus, a better cooling.

just my 2 cent

just wanna know... my hdd fan's speed had increase speed... normal it's lower than 3000rpm... now it's 3360rpm... is it because my hdd became hot and automaticly the fan increase speed to cool down my hdd temp?
