just want to seek an answer here, how many degree celcius can a high speed fan for cpu heatsink cold a cpu? my heatsink fan is currently running at 3000rpm, i decided to get a maybe 6000rpm fan to make it cooler, since my cpu is running at 50 degree celcius. can it work actually? and usually cold by how much?

high speed doesn't necessarily means it will be cooler

what we are looking at here is the cfm or cubic feet per minute - that's the amount of air that is "pushed" by the fans

simply to say, the higher the volume of air passes at one particular period, the cooler it is

of cos, te question remains : what's the ambient temperature? and how invincible is your ears to high pitch 5,000+ rpm fans will make?

6000rpm!!! can u withstand lot of noise...

U don't need to add a high speed fan to cool down you're pc to the max...
The faster the fan, the noisier you're pc will be...

Tell you, you wouldn't want a very noisy pc, it's a headache.
Offcourse, some of us can withstand the noise, but not many of them have experienced the goodness of Silent PC...

In the early days, i've been one of those people who can withstand a noisy pc [at that time, i was using CM Hyper 6+ running at maximum speed with the noise of 46DB (That's freaking noisy, i can hear the noise from downstairs )].
But when i've bought a new heatsink, a new casing for my brother, all the fans in his pc are low in noise, all are below 28DB, that's when i started to fell in love with silent pc...

There i go, sold all freaking noise producer in my pc starting with selling the freaking noisy CM Hyper 6+, then, i've swithched all the fan in my pc to Vantec Spectrum UV Led fans that are low in noise [except for the 92MM fan, it's noisy ]

And today, i'm using Thermalright XP120 + Vantec Spectrum 120MM UV Led Fan to cool down my processor...

I've fall in love with silent setup and will never ever go for noisy fans again...

There's many option here...

1) Use a better aftermarket heatsink [Depending on you're setup]
2) Use watercooling - this is out of you're range. no?
3) Use phase change technology - more out of range.

Are u into air cooled heatsink or what?

i'm using silent setup too. my 2 PC side by side is still more silent than most people's single PC.

first rig
2x 120mm side intake, 1x 120mm top exhaust, 1x 120mm on PSU - fanless heatsink (Scythe Ninja).

second rig
1x 120mm on XP120, 1x120 mm front intake, 1x 120mm on PSU.

Woot, fanless for the first rig?

What kind of procecessor do u use with that passive cooling?
Mind telling me that?

u can use any proc with a good heatsink for passive cooling (provided u dun o/c it lar)

i can even run my stock 2.8E on the xp-90 w/o any fans and it still goes up to 50c max only.

IMO doesnt mean better rpm has better cfm.6k will fry my ears

some fan have low rpm but still high cfm...and the dsB also very low... so dun need high rpm fan to cool down your proc...you can search around at the garage sales there, there are many people selling fan...you can read the spec there for referrence...or you can googling for it...

silent pc is the best setup lah..dead silent is really nice esp when u have pc in u'r room n u don't shut it down during night.. can sleep nicely..

i'm using nidec 92mm with xp90.. sure nidec can run @ 2krpm w/out noticable sound..
but the probs in my chipset fan.. got from allngap.. so loud that i hv to shutdown pc b4 sleep..haiya....miss the old days..

so go for high cfm lo dsb fan.. no need loud fan..
stock amd64 80mm fan oso can cool the temp down to 36C with xp90.. cpu oc a bit only.. n it still shhhhhh..

Yup silent pc the best unliked my roomates stok HSF deafanning to my ears.luckily im a dead sleeper but u need to have a good casing to use fanless hsf rite.since good casing has better airflow

Agree with that, but a case with two 12CM fan should be enough right ??

of course the cable management must be nice to support it ...

in simple term no cables blocking the air flow well some of us is just bad at cable management like me

when i had my delta FFB on my XP120 i also wired it to a 5v/12v switch....

running at 5v and 12v does make a difference.. about 5c difference.

practice, learning from others is the key to success..... no short cut...

i spent hours and hours to study how others do cable management with the same case or same series..

no shortcut unless u request service from Ianho

Double post eeh doom?

TS, you need to choose the right fans, tidy up the cacing's inside you're casing, then i'm pretty sure that you'll get a decent temperature for you're processor...

any recommendation bout the right fan with low dB and high CFM???

My votes goes for Vantec Spectrum 120MM & 80MM UVLed Fans
[except for the 92MM fan, it's kinda noisy ]

Plus bling bling summore...

juz get a big fan (example 12cm).. although it runs on 2000rpm, the airflow can reach 78+cfm.. still maintain nice dBA's.. huhu..

-adios-
