the leds are powered by the rotation of the fan... don't trust me, try vacuuming ur CM Led Fan, u'll see the led light up if the fan rotates fast enough, tried it once when want to clean my fan

if ur looking at how much you will safe at the point of buying then i totally agree with u, but if ur looking at extended value then i think the rm20 dif is negligible...give u a few examples, (tried both fans btw):

1) say theres a heatwave n u wanna keep ur case cool, can u do that with the cm?

2) wanna test ur system for stability...say run orthos or prime95, need to run a few hours right? will u dare to leave it unattended with the cm? btw i ran orthos blend at priority 9 for more than 7 hours, my temps increase by less than 10 deg celcius only with the 2 TT case fans running less than half, nvr even bothered to ramp up the cpu fan.

Hope i dont sound coming off too strong as thats not my intention, only wanna save u guyz the money u "think" you'll be saving.

dat's why u need a case that have a good air flow then ur cpu temp won't be influenced by what fan u are u using...

then u can use CM fan or whatever fan that is slow cause ur cpu temp won't increase or decrease by it

it depends on how hard u push ure system oso. The V Series is 1 of the best air cooling cases around yet I need 4x 65CFM fans to keep the temps inside at sane levels.

If I use the old CM Silents it'll get heatstroke.

use UV version on HR-01 and LED version on exhaust fan....

Yah the light dim and bright according to the speed of the fan ....

yeah, ur right, it depends whether u OC ur system or not

i already using Vizo Starlet, thingking want to try CM fan, cause more silence, but afraid if bought it & try it, the temp increase just be a waste of money

What is u spec and how much u OC ur system ...

maybe i can provide a lucky guess

since i am using all CM silent fans inside a GT-7 (Lian Li OEM-007)....

so, bassically, wht is the best fans for our case??i'm using 3x80mm CM uv and 1xsunon fan...the temp in my case is quite ok for me,even with my presscott which produced a lot of heat..

Anyone have idea what fan controller to use for high performance fan?

Problem that encounter,

1. When full blast it is find with the speed and also 100% fine condition

2. When fan controller are installed, i can control the fan speed, (This is normal right)

3. I lower down the fan speed to minimum, then the fan start to slow down, AND it will come to a stop,

4. So in this case i think the 'controller' are making this problem right?

5. Any solutions? Or any after market controller to solve this?

PS: Not because of PSU not enough power or weak,

The fan controllers can only control normal fans. If u use those hi amperage hi speed fans, the controller cant handle it.

@blackshirt
what fan u trying to control??? what brand and model and what specs?

curious what fan n controlller u using? i think ur fan requires a minimum voltage to run, but anyway it sounds quite dangerous as u or someone might accidentally turn off the fan

The fan is 0.65Amp, controller unknown, campalang i think?

wow...definitely a high powered fan....maybe get one of the fan experts here to build u a fan controller or build your own...http://forum.lowyat.net/topic/312003

Hi guys,

I have been facing this problem which is quite similar.


I am using E6600|Intel DG965OT | cooler master heatsink CPU Cooler (DI5-9JD3A-P9) 4 pin - dinasaur heatsink

I got this heatsink from Startec. At that time, I am really new to cooling.

Problem : when cpu activity high/benchmarking, the fan noise is like vacuum cleaner bcos turning at almost 4000 rpm. (the intel bios that control the fan speed is really not user friendly, u cant set the fan speed lower or whatever speed u wan. all those using intel motherboard will know this problem. software like speedfan cant work with intel motherboard)

This is the link of my cpu cooler loh (really outdated. using presscot for conroe, isnt i noob ): -
http://www.coolermaster.com/index.php?LT=e...9&other_title=0

1. I plan to buy a fan controller to lower max speed to say 2500 rpm. Can I just buy any fan controller. will it work. what need to check on fan controller.


I am using it for HTPC. silence is everything

Iz it ur cooler got wire & connect to the mb ?

I think the cooler fan has got wire that connect to the motherboard fan supply via 4 pin with PWM function. I just dunno my fan how many input amp... just assume can .. assume = ass ?? and ???

frm what i gather abt fan controllers....u need to look out for the amp per channel n also the total/combined amps for all channels, so better not "ass"ume or the controller will not be able to take it

well... i'm quite new to this thread bcuz of my 2 years+ unknown sleeve 12cm fan is about dying, i have to get a brand new 1 to replace it.

as mentioned early(take sometime to read from the beginning ), most of the ppl targeting the silverstone fm122 that come with extra fan controller. i did search for the fm122 in LYP yesterday but fail to get in hand(temporary out of stock?)

so, i need to go for my second choice that u ppl's choice = Vizo! but it seem this Vizo only available for the Wind Storm model as in LYP. the other range like Vizo Muffle MF12025 12cm can't be found 2....

i have no idea wat should i choose while i'm keep looking shop by shop to get a decent 12cm fan! finally, when i stop at allIT....i found a Vantec Stealth 12cm fan that quite similar to silverstone fm122 but lack in 9 fan blades design & fan controller & it cost rm55 too....but it stated "Lifetime Warranty"

i'm not sure this is worth to buy or not.....but the thing is, i'm here in LYP today for a purpose....i really need to get something back & install a brand new 12cm fan, there is no turning back for nth well, it end up with the Vantec Stealth SF12025L. currently the fan quite silent & manage to bring down few C'(5'C). i'm quite satisfied with this SF12025L.

>>>Vantec Cooling<<<

yah indeed it is a fair product ... i though of getting it as well after no luck with the silverstone fan .... but due to my own concern of the price... end up with two cooler master UV fan instead of one vantec fan ....

anyway how it feel with the built quality ?? steady ??
