View Full Version : GlobalWin WBK38 Noise Reduction ?
I just bought a GlobalWin WBK38, and it sounds like a freaking F16. It's driving me mad! Good cooling tho :). I was wondering if anyone had any tips on reducing the noise level ? I have a few degrees to spare if it's possible to decrease the speed of it. Any ideas ?

some list members have tried replacing the screws that mount the fan to the sink w/ dabs of silacone caulk....but this method did not seem to lend a great deal to the noise level.
Depending on what type of heatsink you have, you could try reversing the fan so that it is sucking air from the sink instead of blowing onto it. I've heard that this is the most significant way to reduce Delta 38 ear-aches. Good luck.

Thanks I'll try reversing the fan. Will it reduce the noise by a lot ?

Well, the best way to find out would be to run it for a few min. w/ the regular setup...get a general idea of the noise level. Then switch the fan and see where your at.
Radio shack sells noise meters but that's probably overkill. Your heatsink is alumnium right? I wouldn't advise switching the fan direction if your using a copper heat sink. Good luck, be careful and be sure to let us know how you make our.
The best way is to plug it in to your mb i have a p3v4x and when i do that the fan only spins at 4800 compared to the 6000 when pluged in to the psu try it works and is a hell of alot more quit i have had it there for2months and no blowin headers like everyone says will happen
That may indeed work, but it is using the fan header and the circuit traces leading to it as a crude form of a resistor. I will add this one to my "Bad Electronics" dictionary. ;D
Hoot
Doooh ohwell it works for me and i have had no probs so i will keepp doing it
I have an Asus A7V-E and it can take 7200 rpm - np. So that won't work :)
I'll be reversing the thing in a min now.

How "open" is your case? I've heard of some people insulating the insides of their cases with thin foam (the kind that comes in mother board boxes). It's not something that I would want to do myself, because I think that the insulation would retain some heat in the case. But it could be a solution to your problem.
I just reversed the fan - and it's even noisier. I think it maybe was "reversed" already.
I'll try putting some "foam" inside.
There are a couple of ways i have tried:
1. Reduce the voltage of the fan, hence drop the RPM and the noise, this can be done through a Fan Bus or through hard wiring. The downside is not as good cooling.
2. I cut up some ear plugs and used these like shock absorbers under my fan, inbetween the interface of the heatsink and fan.
3. Buy a larger fan with the same or higher cfm but with lower noise rating, i tried this and it worked great, but went back to the delta when i started hardcore overclocking.
Good luck
the best way to reduce the noise of the WBK is to just buy a 36cfm 80 MM fan and stick it on there. you will get almost no loss in cooling and definitely save your ears.
Thanks for all the input guys :)
I just put my old fan in 'cause this was unbearable - losing the overclocking abilities there :(
Anyway I would like to make this work 'cause I'm utterly broke - no money for a new fan :) I don't even have income.
You mentioned something about reducing the voltage to it ? Can I do that without being a total electronics guy?
Sure can just put the red wire onto the yellow one on the 4 pin connector and there you have an easy fan mod.
That is the red wire from the fan to the yellow of the PSU 4 pin connection.
The red wire from the fan is already connected to the yellow wire in the 4 pin thing.
The black wire from the fan to the black wire beside the yellow on the 4 pin.
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Yeah that should be it, no diference ?
try the red on red then
Yes black to black
That was how it was delivered. It has a normal thing that u can connect to the cpu fan outtake on ur mobo, but it also has one where you can connect it to the power supply - with a normal 4 pin connector.
The power supply connector not the mobo one is what i am talking about, leave the black wire connected and alternate the red wire form the red to yellow pin in the connector, you will find one is at 12V and one i think is at 7V or something like that.
Being a DC fan when you lower the voltage the RPM drops proportionally, hence the noise drops,
I did this with a delta i had and once i had the cash i bought a fan bus, which allows me to switch it when i want.
Hope this helps
Yeah I am also talking about the power supply one - 4 pins, 1 red 1 yellow and 2 black wires. The red wire from the fan goes to the red wire on the 4 pin connector, and the black goes to the black beside it.
If I reversed it from there, wouldn't that just give the fan MORE power ?
Arg I just F***ed up that - the red wire on the fan goes to the YELLOW wire on the 4 pin connector - by default.
Take the "fan 4 pin connector" and take the red wire out and put it in the slot so it lines up with the yellow wire of the "power supply" If you wish change the black over also.
The red wire runs at 12V
The yellow runs at ~7V
For the power supply.
You may need to cut and strip a wire or two, but that is as technical as it gets
LoL--- I could need a sketch of this - i'm lost..not very technical am I.
The red wire from the fan is already in the slot together with the yellow wire from the power supply.
Np
Well try it with the the red wire from the power supply, if the fan increases speed and hence noise then well sorry this mod is not 4 u.
When you do get the cash, fan buses are pretty cool, and it allows some adjustments of fan speeds.
Or just get a bigger quieter fan, when you can
Yup...and that's the "easy" solution... lol, I don't have any income. I go to school...:D
...............................................
Been there buddy,
well you can still give it a go, but if it is already connected to the yellow then i dont think it will work the way you want.
Beg borrow or steal 12$ and get a new fan from a swap meet
lol :) After I just spent my last 30$ on this f*king fan :D
lol
well i know the feeling i put up with my delta for a month before i changed it, now its back on with a voltage mod through my fan bus

could you put a 60x25 Y.S Tech 26CFM ( 3pin ) on it so it would be quieter? 37dB rather than 47dBs for the delta.
I agree with el. The ys tech or a sunon 60mm high output. Both will be much quieter than a delta.
Switching the voltage to 7v is a ok idea for a case fan.
Using 7v on a 12v fan can cause fan starting problems, not good on a cpu.
The fan will run at a lower rpm and reduse the airflow anyway so may as well just get different fan.
I think actually that instead of a new fan, a weaker fan, or anything like that - i'll keep my old fan in, keep the duron at 900 instead of 1000, and wait till I can get a hold of one of those boxes to have ur cabinet in, sound proof with ventilation, ACE! :P
and it is actually only 34db which is even better!! only 26CFM but hey if you chips run cool! I hate the HAIRDRYER!!!

You could always place your whole system in a closet hehe, stuck mine inside within a day of installing the cak38. As a bonus, on friday installing my airconditioning unit... im looking into a small amount of tubing to funnel the cold air first into the closet, then the rest of bedroom gets the waste temperature. I might add i placed a large styrofoam block between the sliding doors and the computer, dropped it down even furthur.
MInd you a temp solution, within a few weeks think ill be water cooling.

you have 3 options, get a ys-tech which is still quite good, find a way of reducing noise (cover the inside with foam or cork) or get a really loud stereo
LoL - so that's why you're most deaf - massive stereo.
I thought about putting it in a closet or something, and that's my plan - making/buying a case (wood or other) that will shield the noise.
Do the voltage mod or buy a voltage regulator, dropped my delta from 7000 RPM to 4200 RPM and the noise is much better,
Still when i am playing games or doing some hardcore number crunching, like so 3D cad then i just switch it back to 7000 RPM and live with the noise,
Its like having 2 coolers,
Funneling a big fan down didn't work as well for me, but..............
