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-

A 120MM fan with 2000RPm is noisy...

It's not even near to silence...

I think Thermaltake UV 12CM fan should be nice .... reasonable CFM and DBA..

around 49cfm and 22dba (based on experience)..slightly lower than VIZO ....

Vizo got my vote the UV LED ones noce to look and also pushes good cfm but just a tinny louder.u wont hear it if u use headphones

I agree with what lucifah says... its the air flow (measured in cfm) that matters.. because I'm currently using a Nidec 92mm fan for exhaust (but I've also tried intake) and I can adjust the fan from 1200+ rpm up to 5700 rpm and I tried to play around with it increasing and decreasing the fan speed, it didnt do much help in cooling my pc. But as to your usage on CPU cooling, I'm not sure how much it goes but it really wouldn't make much of a difference... plus, like what everyone said, the sound of a 6000 rpm fan will make u deaf in a few weeks man...

That's for sure men ... but usually i run my system in aircond room that has silence feature... therefore the sound of my system definately overwhelm aircond noise...

that's why prefer damn silence fan .... since ambient temperature is lower....

dead silent i guess CM UV fans la is the most dead silent.since my room is a sauna no choice have to break the sound barrier

How many DB would you guys consider to be starting to get noisy already?Well, i have seen many high speed fans especially the delta ones which does produce a very high amount of DB.Seem noisy enough to me..I currently have one 12cm Delta fan and its producing a great amount of noise.Planning to change to other type which is silent but still be able to provide ample cooling functions.Any reccomendations?for 12cm and 8cm...

Well, for me, 40Db is the starter for breaking the "drums" in my ears...

how loud 40 Db is?

can tell me,like what sound that produce the same Db?

Err...
How to explain aa...

Hmm...
Dunno liao...

so if that case,how can u measure that Db are loud enough?

sorry,my pc dont have Db meter

No pc has a DB meter liao...

You can always look at the noise of a particular fan on it's packaging or maybe u can google around in google about any fans noise...

Been looking for the answer too, heres a comparison chart

http://www.gcaudio.com/resources/howtos/loudness.html

That link didn't really help as it's pointing to those noises that is above 60DB...

yeah...thanx for the link

very helpful

Anyone got recommedation of 120mm wif 70cfm above to mount on my scythe ninja? My cpu temp idle is 47C le...full load is 62C le...I really wish to noe y....I use the original fan given. I am using P4 2.8E....Can someone teach how to cool it down wif max temp less than 50C....Help....

The stock fan that come with Scythe fans are silent fans...

My suggestion is go for Vantec Spectrum 120MM UVLed fans...

I chk the Vantec Spectrum 120mm , the cfm is 36cfm compared to the stock fan which is 46.5cfm.... Somemore the noise level for stock fan is 24dbA while vantec is 36dba le...It's no point to change rite? Correct me if I am wrong?

Is silverstone fm121 this fan good? Anyone use before?

http://www.silverstonetek.com/products-fm121.htm
It has very high cfm with max 110cfm...Anyone use before?

Don't look at Vantec's Website, they didn't bother to update the wrong information about the CFM...

If you go to LYP, and check the packaging itself, there, it states that the CFM is 69.34CFM...

The information in Vantec's webpage is incorrect liao...

The silverstone fan does seem good but its kinda hard to get over here in malaysia.Vantec is a nice fan that does have some recommendation last time i hear from them.Was planning to get the silverstone last time when i was in LYP but its kinda expensive.Almost costing about RM80..

there is bulk for silverstone fans..the forumer daze or something..60 bucks for it

noise level very hard to explain one..its very personal thing..some may feel 30db already loud..some can tahan even 60db

if dun like bling bling like me panaflo n delta hook to fan a controller is very nice..not dead silent can hear "wushie" wind noise but not annoying

Well, those delta fans do seem good in term of speed/noise level but not really for absolute dead silent.The noise level is still high compared to other brands..The Silverstone does seem really good in term of speed and noise level but too bad the price is kinda expensive..

Anyone tried those CM UV fan?How good are they?

Delta 120x38mm FFB1212EHE

How bout this fan? this fan has 190cfm le?
http://epowerhousepc.com/delta-120x38mm-ff...2ehe-p-585.html

Will it decrease my cpu temp a lot if compared iwf the one i hv now which jz 46cfm...If i use this, then my temp sure going down 5-6c? correct?

yeah itll decrease ur CPU temp alot .. but at the cost of ur hearing

It'll surely reduce the temperature, but it won't lower the temperature more than 5 degrees...

For a 5 degrees less, can't you stand the noise?

Then could u tell me how cum my nija plus cant tame down my P4 2.8E? please tell me...I apply ar5 also le...Is it possible my mb sensor spoilt? If so how to measure the temp correctly?

Then could u tell me how cum my nija plus cant tame down my P4 2.8E? please tell me...I apply ar5 also le...Is it possible my mb sensor spoilt? If so how to measure the temp correctly?

I've used to have a Pentium 4 3.0E [oc'ed to 4GHz] used with CM Hyper 6+ running at 44degrees on idle...

Scythe Ninja stock fan is too slow...
You have to change to a higher CFM...

IINM, Scythe Ninja stock fan is set to run on 1000RPM or lower...
It's too slow...

If you wanna change, just change it to a little faster fan...

Look around for a fan that is 1600 - 1800RPm
That should help...

R u sure is that rpm and not +/-1200rpm max? Pls dont say scythe ninja got 12 heatpipes

Guys ur having heatpipe discussion on two thread wats up with that!

I didn't say anything about heatpipes here...

neoxz did, not me...

Ninja plus has oni 6 heatpipes...the max speed for 120mm fan is 1200rpm..... But i use speedfan to measure it...mostly run at 1150rpm

You want silent fans which push decent CFM's? You have two choices IMHO locally, either a Pabst or Panaflo (preferably those made in Japan). They are the best in terms of a CFM/noise compromise. Although given the chance, I'd get Yate-Loon's instead

for example this

Here's a good guide

http://www.silentpcreview.com/article63-page2.html

And trust me, the Delta 120x38mm FFB1212EHE is a waste of money as I'd can assure you, you cannot stand the 60dBA noise it produces (equivalent to a noisy coffeeshop)

http://en.wikipedia.org/wiki/Decibels

And those using scythe's if your fan is coded Scythe S-FLEX SFF21D then it's about 844rpm.And there's nothing you can do about it as it runs at those rpms at even 12v. So for a good CFM fan. look for those that push past say 60cfm and have a noise level between 40-50 dBA and you'd be assured with a livable day to day use fan

on the contrary, i'm using an OCed rig with passive cooling. totally reliant on casing air-flow. when playing game, i'd better run my exhaust at full speed. the exhaust is a Silverstone FM121. intakes are 2x 120mm Coolermaster LED.

my processor is Athlon 64 2800+
stock - 1.8ghz 1.4vcore
OCed - 2.5ghz 1.5vcore

on full load, could reach like 70c but that's based on speedfan.

the other day, i opened my secondary rig and got a shock (well, not exactly). i was only shocked that the CPU fan wasn't running, but since it's a Sempron 64 2800+ and on an XP-120 - it didn't hang, luckily i wasn't folding as well.

I think of buying a silverstone fm121 cause i read a lot of review from google...mostly say wif the fan + ninja plus, my cpu temp will b lower....Do u all noe wat is the market price for silverstone fm121 and whr can i get it? I c bulk there got one fellow sellilng at RM60, hvnt plus delivering yet le..... I c the silverstone dealer located at imbi plaza....

i saw the 8cm version at AllIT Hypermall before .... and the price is around RM 30 if not mistaken...

i recall there is 12CM before but no longer in stock....

Well, the 12cm version is available in compuzone for about RM80. The day when i was at ALL IT, they dont have SilverStone fan anymore.All that was left is a 9.Xcm version (cant remember closely) which cost about RM20++...

The SilverStone fan does seem like a good choice for fan.Low noise, good speed and CFM...

the FM121 isn't silent at full speed.

The FM121 was only interesting to me because of the 11 blades. More blades = better at pulling air through a intake filter. But the noise at max + the price = big no no.

I'm more interested in the newer Scythe fans now, especially after SPCR's review showed it's on par or better than the Nexus fans. Too bad I haven't seen them around LYP though.

Based on specs, hv to agree, the fm121 is quite good, altho i havent heard it running, anyway the speed can control so shud be able to run silent n currently also no stock.

This post has been edited by cablesguy: Nov 24 2006, 09:04 AM

Might grab a one for testing purpose ..... hopefully it still available ....

will be going to LYP this weekend or today after long 9 hours of class

After u test, remember post ur result here....Tell me ur buying price and which shop o...Thanks..

even at half the speed it's pretty silent already.

i run mine at around 700 RPM or so for silent mode.

at lowest, it goes at 300 RPM. why am i not running at 300 RPM then? that's cos my FM121 as the exhaust, it monitored by my Akasa All-In-One and once the speed goes below 600 RPM the fella will sound the alarm and unfortunately 600 RPM is as low as the trigger goes for the AOW. the speed of my FM121 (and my other 2x 120mm CM LED) is controlled by my Vantec Nexus.

Why don't you guys try Pabst's? Their available reconditioned over at Imbi Plaza. Worth a look since they'd cost between 30 to 50 ringgit

Well, they are a good product but too bad the price is far more expensive than the other fans so they are always overlooked.Not many people would spend over RM60 just for a fan though...

Well, does the full speed really generates alot of noise?You ever use the Thermaltake Smart LED fan before?Cause i have one currently as my exausht at full speed.Was in consideration of replacing it with the silverstone and placing the thermaltake for the front intake though..

I did when I bought Japan-flo's. Costed me about RM65 but worth it as the CFM is about 80 plus with slight deep whooshing sound.

The silverstone's so make a bit of a noise at full speed but nothing to really be bothered about especially in comparison to your SMart LED fan actually.

Any photo to show how the fan looks like

Totally agree, formal Blue LED owner here .. 2 some more which i left it inside my pile of junk yard......really noisy unless go down to below 1K .... .

What are the specs for Pabst's fans?

I'm not sure what's available in stock at Imbi at the moment. But you could PM empire23 who has 2 of them to give you the specs. And these fans don't mind running at 7v unlike some panaflo's (which will click at 7v)
as for specs, here's what I can pull for the 4412FGL model

http://www.madshrimps.be/?action=getarticle&articID=421

Do u all noe any 120mm fan is below RM50 and hv below 35db and hv 100 cfm above?

Cheap sale

None to be honest for all three variables combined for brand new. And any 120mm fan above 100 cfm WILL not be even below 50 dBA trust me.

So far I oni know that silverstone fm121 got such spec wif around 100 cfm with 40db....
Got other fans?

Cheap sale

This post has been edited by hahaha85: Nov 24 2006, 10:55 PM

100CFM with 40db is considered good enough liao...
Not so noisy, not so silence...

But it's a "NO" for me as anything more than 36DB is considered noisy to me...

same here.. and my friend storm721984 just got Silverstone FMA 122 from LYP today ...

still waiting for his testing result....

Which shop in lowyat? and how much?

Cheap sale

MyPC at RM55 but one unit left ....speed controller is black aluminum

Well, i think its hard to find silverstone fan in LYP.Its either too expensive or there aint any stock left but do try finding.The last time i see, Compuzone and ALL IT have it there..

OT: I think u can try put that link at ur sig..

just few days didn come bk and see this thread, so many reply liao...thanx guys for all the info, i think im goin to stick to my current fan lar, i think the most im goin to do is to clean the dust accumulated inside the casing and fans. and then reapply a new heat conductor for my cpu. rally weird, few months ago my max temp for my cpu is 42 degree celcius, idle is around 36 degree. but nowadays, it reach 56 degree and the lowest idle temp is 44 degree. even after i clean everything inside the cpu, and even apply a new layer of heat compound. wat happening arr?

Maybe because the new layer of thermal paste is too thick?
Who knows...

Did you clean the old thermal paste before applying the new layer?

clean everything. its not the 1st time i apply compound lar, i do it many times liao....an even thin layer is sufficient.

Then there must be something wrong with the temperature sensor probe...

Ur friend get one is fm122 not fm121 a? so how is the result?

Hi all, manage to test the silverstone fm121 and the thermaltake smartfan blue led, this is my personal observation, firstly.....i wouldnt run either at max speed, theyre both loud, kinda like in a crowded coffee shop, but the thermaltake has a kind of whine or humming sound which i find a little irritating at max. The fm121 is just that..... loud. Then again sound is very personal.

Pushing air wise, fm121 is better, this is putting my hands abt 6 inches away. Putting my hands behind the fan, abt 6 inches away, the air rushing in to the fm121 is also greater...at least it felt that way, in case u wanna use as an exhaust.

The fm121 controller also allows for better adjustments of fan speed, altho not by much but noticeable.
Both got yellow cables to detect rpm.

But i think if ur looking for a high cfm fan with led the thermaltake is a good choice...as is its capable of pushing alot of air, my 2 sens hope this helps.

FM121 at full speed loud? yeah it is but it isn't that BLARING kinda loud yet.

i can bring out my YStech 70mm and it's still louder. so are my other fans in the fray.

specs is 93.7cfm, 46.5 db, i shud hv put out of topic a little...forgot. wanna test take out test for hs too tedious la....

The noise of this fan is more than silverstone fm121 le... Test the hsf and let me noe lo if u got test...Thanks ya

np, plan to test on hs anyway but not just yet...just cable managed n abit lazy also .
Anyway base on db agree with u the tt seems louder, but not sure whether the specs accurate or not, manufacturers bs all the time, actually both sounds equally loud to me n i dont think many will wan to max out the fans continuously...really cannot tahan.

Ur friend get one is fm122 not fm121 a? so how is the result?
according to what he said and the sound level i heard over the phone ... seems like quite reasonable ... however FM122 push a lot of air.


i have the blue LED fan and it was kind of acceptable even run at max ... but not for those that looking for silence solution .... unless u lowered RPM to 1K..

If not mistaken, the cfm of fm122 is smaller if compared to fm121 and the noise level of fm122 also larger than fm121 le... Then how cum fm122 push more air? How is the temp?
