OK. I noticed there's been a lot of threads about fans. Let's put it all here for easy referral n discussion by everyone.





Link added. Thanks to vassale for the very informative link.
Here's a comprehensive test of 26 types of 120mm fans.
http://www.xtremesystems.org/forums/showthread.php?t=137832

Good idea... threads that is biased to personal preferences has been popping up so often lately.

is there bigger than 12cm fan (25cm?) that i could find?
*no table fan lol

actualy there is 14 and 25 cm fans bt nt that ive seen any in malaysia bt performance pcs sell them....

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

*edited typo

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?

what do you mean by hard disk fan? you mount it to a fan controller 5.25 bay? it depends on the temperature then. the fan controller will calibrate the fan speed according to the temp. you don't want to run the fan at max speed with screaming sound all the time right?

oh... forgot, i mean the fans that attach in hard disk cooler

I have another question. Apparently my casing side panel has some 80mm blowholes... should I leave it be or get someone to mod it and close it up with acrylic and make it like 'air tight'? Which is better?

Cos right, when I use paper to paste up the blowholes, the temp of my CPU rise up by 3°C.... so how ar? Anyone knows what to do?

^why do u wanna close it in the first place?? why not add an 80mm fan there? or why not just leave it as it is?

if ur worried about dust coming in from the blowhole.. then just get some women's pantyhose, cut it up and cover the hole with it. itll act as a filter. but remember to clean it out once in a wihle

sidepanel is the best place to supply the CPU area with fresh air.....dont block it la....

I guess I'll just leave the hole there as it is. I dont wanna use a 80mm fan cos it will disrupt the airflow.

Hey AllnGap... I finally kena cut by your badass Nidec fan

lmao... post of the week. high cfm? how high does 22cfm goes? and how quiet is a fan that has 120cfm with 55+ db?

Evercool green fan 80mm spin at 1600rpm only with very little air flow but it is ideal for dead silent setup.

Here's smtg interesting. Would you guys sacrifice performance for SILENCE? or silence for PERFORMANCE

If me I still prefer silent over performance since my rig not produce so much heat.

no need to headache about cooling la
just add an air-con, then it will be the greatest solution for every heat
hhaaaaa

Not funny...

This isn't a thread in the kopitiam and its only for casing fan enthusiasts to ask their questions and discuss stuff. So please... keep ur lame jokes to urself.

There is no need to sacrifice anything if u strike a good balance. U can haf performance n silence together.

As u can c in my sig. My King Kong rig is highly overclocked therefore it produces an incredible amount of heat. My CPU, motherboard n graphics cards r like toasters. Seriously can bake bread in there without proper thermal management.

With a good case, good fans, King Kong is as silent as a mouse now. Even my Ferrari laptop is louder than King Kong.

WHat exactly are good fans? I'm kinda keen in learning how to secure the best way to cool my casing thru fans...

There is no exactly perfect fan when comes to case cooling ... it's more about the design of the casing and flow of the air.....

any medium RPM fan that push around 45+ CFM will do good enough .....

anything higher would causes excessive noise ...and the best is to have clear way ... more things that obstruct the airflow would also causes noise ...

example is the HDD cage area that always comes with 12CM fan...of course there is no solution for this scenario unless u water cool the HDD...and remove the fan...

but other component such as chipset and gc ram would need the airflow to stay cool....

What bout this?

Enermax Fans...

I personally think one of the fans I got from AllnGap is damn good considering CFM-DB relationship. Am using one on American Apathy and it can be considered silent for the CFM it gives.

NMB 120mm low speed

Model : 4715KL - 04W - B19
Dimension : 120*120*38
Speed : 2300 rpm
Airflow : 83 cfm
Noise level : 37 dBa
Current rating : 0.27 A
Power consumption : 3.24 W
Link : http://www.nmbtc.com/index_f.html
* no RPM
* suitable for all case cooling and CPU cooling

You can check his fans thread. Comparing this fan at RM25 to crap CM's RM29, this one will beat the crap out of all CM fans. The down thing is its kinda heavy to be mounted as a top exhaust unless your case is solid made (unlike my cheap flimsy case on AA)

i've heard that side blowholes really disturb the airflow of the casing.. that is why casing that have side blowholes usually have the "hood" or "funnel" that supplies the fresh air directly to the cpu's hsf.. so i guess if you want to use the blowhole, its better to a hood

if for performance,i refer to Vizo fan...it give good cfm.but produce some sound

if more efficient,try to attach duct directly to the side blow hole fan.it will give good air flow to the proc hsf..

vizo actually.. is vantec rite if not mistaken..
juz rebrand
i use UV led vantec.. but remove the led part.. haha
damn nice 2.9k rpm... with the nice price..

Err, why did you remove the UV Led?

That's what makes the fan uv reactive part lights on...

bcoz, i hav UV.. that's enough for me..
like wut post before said.. the led bling bling at nite.. hard for me to sleep..
super cheapo with spin the globe rpm hhahahaa

but the noise..

actually the vizo fans are not bad, 1) they are extremly controllable,(the whole range 80,92,120) 2) they are quite cheap for their performance, 3) if u set it up the right way these fans can push lots of air with minimal noise. heck i modded a 80mm vizo uv onto my stock hsf, put it to 1300rpm, the gc artic silencer is louder ..... n it still keep my temps alomost the same,~2+ .

Agree with lolhalol... but it still kind of noisy if run at default speed ... although the color matching would be nice for UV themed case....

im agree with u

vizo fans can push lot of air...

like hair dryer

u obviously have not tried the delta FFBs

only slightly different ma...

both can make hair dryer

SLIGHTLY?????? SLIGHTLY??????

wah liao...

u OBVIOUSLY have not tried the Delta FFBs

60cfm vs 190cfm for the 120mm version

u think leh? slightly or not?

ho.. the different is by at least 3 or 4 times more .... maybe u could visit OC pardise...

see yourself the different ... it's like u can feel the airflow even at half a meter away ....

no way to compare....

i have the 190cfm ffb delta fan. the whole fan is so heavy but due to the raw juice that's in the fan, its capable of propelling itself and run around the room if its not fasten. personally i think the fan is not practical cause of the terrible noise. it's mention that its not compatible with sidewinder controller. is there anyway to mount a VR to it?
