[Official] Corsair Graphite Club - Page 421

Hi, i have some free time, so here is my new fan controller.

i decided to use only 2 channels, but "stronger" transistors. i have 6x120mm on first channel and 2x200mm and 1x120mm fan on second channel without any problems. regulated voltage is from ~5V to ~11.5V. my scheme is exactly like corsair stock controller's one, but i used only 2 transistors/channels and capacitor (it helps to start fans on lower voltage). i also used little heatsinks on my transistors, because they are heating a little. but it is also possible to use more transistors (3,4,5,...), create more channels and use less fans on each channel to avoid heating and cooling at all. i just grabbed first available parts at store and tried that. i also had to move my DVD drive to the bottom, because heatsinks of fan controller are too big to hide there. maybe i will leave only potentiometer up there and hide rest of fan controller somewhere else in the case. i paid around 3€ for whole controller and i still have many parts left

Try spacing it away from the grill with some washers. The fan sitting directly up against the metal grill is what generates the whine. Hope that helps a bit.

100 CFM for the rear exaust? I thought high cfm was for to suck air in.
Thanks for all the replies btw.

Update.. no pics but..

Total fan count in my case has gone up. 6x 120mm fans, 2x 80mm fans, 1x 200m fan, 2x 140mm fans, 2x40mm fans.

At 100% it sounds like a jet fighter with an afterburner.

Thanks . That definitely makes sense. That is probably why putting the filter in my cm690 stopped the whine. It created space between the fan and the grill. I'll post back with the results.

what cathodes do you have in the bottom. they look pretty bright. i got some horrible ones and want something better likt these!





any anyone on here w/ h100, what do you think im on the verge of getting it

H100 is great..



Fits with 4 fans. 2 fans are good enough too for a 5Ghz OC on 2500k.

Temps: 21'C low, 57'C high

I don't bother using them any more. I used to use them when I thought my case needed something, but this case is so nice I just don't put that stuff on it any more.

Mind if I ask you some dumb questions?

are you sure you have the polarity of the LEDs correct? They will only light up in one direction. If you connect them direct to 12V forward biased with no resistor, the LEDs may blow. You need a series resistor. Check here:

http://www.hebeiltd.com.cn/?p=zz.led...tor.calculator

Usually, on round LEDs, there is a flat edge on one side. That flat edge should be the cathode. The cathode should go toward ground, and the anode (through a resistor) should go to the +12 or +5 volts (I'd use +12). In the pictures on at the link I gave you, the flat line on the diode symbol, at the point, is the cathode.

I have not looked at my NZXT fan circuit board yet, I just ordered the LEDs on Monday (got them for $1.05 ea CDN) so I likely won't know until sometime next week.

Can you take a picture of the NZXT board and post it for me? I'd look at mine, but it's a lot of work to get that fan out now since I added two intermediate fans in the case. I have to remove them to remove the drive cage so I can get the fan out.

Did you want everyone to discover that Vengence Ram trick by themselves? You didn't even point it out in your post. Share the knowledge brotha'. The Deise holding out on us again? The brainwave only hit me independently on Monday Was just about to post it myself Up till then I had my H100 rad at an angle and with about 1/3 of the rad obscured. With the ram HS mod, while not being able to line it up with the 120mm fan holes because now the VR heatsink is the limiting factor, at least now there is only about 1cm of the rad not under the pull fans. I can't see that hurting efficiency too much. I'm running the 2 stock fans in push and I just fitted two Ap15's in the roof for pull.







'By your command'



Black, red and yellow left side 12 o'clock are the 3 pin fan wires. I had to extend the led wires and the are solder to the + & - terminals around the pcb. Black is - and yellow is positive. To discern + & - of the leds I noted that the silver coloured wires where connected to the neg terminals and the copper coloured wires went to positive and thus I extended the silver with black and the copper with yellow.

I figured I wouldn't need a resistor because there were 4 white LEDs and thus in series they must be near 12v. Aren't white leds about 3v?

The lower cfm brother led version of this fan does not come in a white version so maybe there is a resistor under the plastic for lower voltage colour leds but then again why didn't the other working leds not work powered in series straight from a molex. Black and yellow on a molex is the 12v isn't it?

In case its usefull info, those solder points without wires in the 12 o'clock pcb position is where the led on/off switch on the brother fans connect. I thought I had cracked it when I discovered a photo showing this, However, even when I bridged these points the leds stayed off.

Got my Windowed sidepanel and String LED's the other day too.





NZXT sleeved 24pin



Tidied up some cables



Decided not to put the corsair fan back on the case as rear exhaust after having it on the H100 as an emergency measure after I fitted the AP15's. I feel its just robbing the H100 exhaust and with no fan on the back the H100 is probably pulling air in from the back which is going to be hot from the PCI exhaust. So I blocked it up. Adding up the CFM from the 200mm and 120mm front intakes I get 213 cfm and exhaust is about 160cfm. ie. Positive pressure. Its only when under heavy load that the H100 exhaust would kick into higher gear and increase exhaust CFM to about 10 or 15cfm higer than intake. ie 225 cfm



Then I sat back and dimmed the lights

Forgot to mention. Another fan output on the 600T fan controller went pop today. Noticed my 200mm not spinning. Have moved it to a fan header on the modo. Could the non working LED's on the NZXT have caused the 600T fan output to die?
