5V and 12V onboard locations for fans

I would like to add a fan above the cpu heatsink.
1) Where would be a good place to get 5V where the current is not going to screw up the circuit?
2) Same for 12V. On the IO the 12V was on continuously so long as it was plugged in (even with the power button off). Is there a place on the GCT where there is 12V only when the unit is "on"?

Not a bad idea, but over the past tow weeks, I've found te GWCP to run very stable with no fan.
Have you been able to overclock it

Overclocking has already been answered in another thread... NO.

As far as adding a fan. One suggestion. I added a 5V or 12V fan to my I-opener. I soldered a connection from the 19V supplied to a voltage regulator. Trouble is that the fan is always on since I went straight from the source. Depending on the current, which I don't think is much on a fan, you should be able to wire a transistor from the IDE connector pin 42 or 44 and use it as a control to turn on the voltage regulator. This should solve the problem of a fan always on. Maybe some day after I finish painting the house, re-doing the bathroom, and getting my other hobbies and work done, I'll try it out. But in the mean time maybe someone else might want to experiment with this idea. Should also work with the GCTP.

Hum...what makes you so categoric about not being able to overclock ? I remember making that suggestion and I don't think anyone was able to give a final "no"
There is PLL-IC chip in there that controls the FSB speed. It probably wouldn't be very hard for ODA to build a plugin for SoftFSP, if he were still supporting SoftFSB that is.

Hum...I don't think any overclocking can be done on the GWCP. I did some research about that a couple of weeks ago, do a search. "


I really dont understand this at all. My message was for a SOFTWARE OVERCLOCKING PROGRAM, and you gave me a hardware OC answer, which was NO. Then you change you answer again for the hardware OC?

What's your problem Wordsmith ? I said I didn't "think" overclocking was possible, that's not especially categoric is it ?!

The scene: A small town kitchen, somewhere in mid Kansas, the wind blowing the sunflower fields as though it was a sea of urine. While the sun is rising ever so slowly on the horizon. Now you look into the house and see a boy sitting at the table, while his mother is standing in front of the stove, scambling eggs in a frying pan.

"Yeller!", his mama says. "If I said it million times, stop asking me why I use a pan to cook eggs in!"
"But mama", young little yeller asks, "Why do you have to turn on high, don't you think it would be easier to just have the electric company change the 60 hz cycle on our power lines to.... Oh I 'think' 240 hz. Yeah moma, that would make the eggs cook much faster, and you wouldn't have to ever turn the oven on high again."
"Yeller!", mama cries with a grating sound, "stop all that foolishness, pappy already said that just won't work in our house". She reaches over and takes a drag from her cigarette. Just then an ash falls in the eggs, that now are just about cooked, mama just continues to stir the eggs.
"But why?", asks yeller so foolishly.
We now hear footsteps.
"Oh NO mama!", cries yeller, "it sounds like pappy"
"Where's that idiot son of mine?", shouts pappy
"I'm here pappy." says young Yeller, with a slight tremble in his voice. "Do you know what your idiot son is asking now?" says mama, as she lifts her leg to cut a nice juicy fart. "Don't tell me ma', it can't be nudder one of those I know it all l'ectric ide'ers agiin", "yup!!" says ma, as she pours the eggs onto a paper plate. Just then as ma is reaching into the fridge for some of that new GREEN ketchup, we hear !!!WHACK!!!, mama, doesn't even flinch, as though she's heard that sound a hundred times before. Young little Yeller laying on the floor, looks up at his pappy and says, "Pappy, what was that one for?"

Pappy squats down next to Yeller and say, "boy!, didnt I teach ya' anything by now". Little Yeller with a tear in his eye says, "yes pappy, you taught me how to make up stories at school for answers I don't know, just in case I'm lucky enough to get the answer right and get credit for it"
Pappy squats a little closer to Yeller and pops him in the head. "Pappy, now what was that one for". "Boy!, canchya just fir onece, sit down there at the table and just keep yer trap shut and eat yer vittles". "But pappy it's true, we could write to the 'lectric company and least ask um".
Mama, takes the bottle of GREEN ketchup and pours about half the bottle over the eggs, and says, "just the way he likes it". She brings the plate to the table. Pappy moves around to the other side of the table, and poor little Yeller gets up and sits. He begins to eat the eggs. "mama, you just make the best eggs". Pappy looks at the plate with a mound of GREEN ketchup covering the plate of eggs, reaches over the table and smacks Yeller up side his head again! "pappy, why did I deserve that one?", ask Yeller. Pappy stands up and says, "ya kant be my kin, no one in our family has ever been so darn close to a moron", he looks over at mama, "are ya sure we picked up the right one from the field when yous was givvin birth, or did you pick up that watermellin instead", mama looks at pappy and says, " I just can't remember"

The topic is fans not overclocking!! DAMN IT!

LOL Vagitizer!
Me thinks that may be hittin waaaay too close to home for 'ol Yeller.

But seriously, there seems to be one of those self-righteous village-moron types in every communities, including just about all mailing list\forums on the net. We all just have to be thankful that Ol Yeller is taking the honorary position and carrying all the mental\psychotic baggage that comes with the deal ;)

Yellow - Here's a clue. When you see more and more people speak out -against- something\someone... there may just be a chance that they're not spewing pure bs.

Boys, boys, in case you have forgotten the topic of this thread is:
Is there a good place on the motherboard to tap 5V and 12V? And for the 12V is there a place where the 12V is only on when the unit is turned on?

So far there's been one followup post by Vagitizer that has been on topic and the rest has been off topic or bickering.

thanks O2 but I've already been there. In fact I've bought the parts from digi-key to build several of them for my IO's. If there is a "12V only when on" place on the GCT m/b then it avoids having to build that circuit.

thirdRowJoe - Point taken, in theory. In practive, what hurts your argument is that you've just registered yesterday and are probably another incarnation of InMemoryOfFred/Feddupp and God knows what else. Makes it easier to write "more and more people" when you keep creating new IDs...
What's your next name, FourthDayIdiot ?

yellow1,

If you can't take the heat, stay out of the kitchen. You would have been tossed off the island in the first vote....

Steve,

If you're not using your standalone modem (the one mounted to the 4 standoffs), you can pull 5 volts off of CN13. Pin 1 is +5, pin 2 is ground. I found some little Panasonic fans at the local surplus outlet here that run on 5v, they only put out .92cfm but are reaaally thin. I just want to blow some air past the drive and heatsink, these should be perfect. I'll post a link to the Panasonic spec sheet when I get back to the home front in case anyone else is interested....

B'Dog,

I'm assuming that you are refering to these fans available from DigiKey, part no. P9777-ND ($28.13). You mentioned that you got it from the local store. Can you tell us how much you paid for them and/or where you got them, so that I can try looking around for them. Any help would be appreciated.

Ballo,

They came from a local electronic surplus store in the Houston area, they seem to have a few more than the 1(!) piece Digikey has in stock. I get by this place about once a week, and would pick up some for anybody who wants one for $13 + $4 Priority Mail. I can take PayPal, email me at BubbaDog56@ev1.net if you're interested....

B'Dog, I'm going to try the 6mm fan from here:
http://www.excess-solutions.com/index.htm?fans.htm
I was planning on using it above the Q16 heatsink on the IO's and thought I'd also try it over the transmeta heatsink.

Excellant find too!!

One thing, be carefull of the ones that pull the higher watts, the ES1309 near the bottom requires almost 3 watts! You might put too much strain on the CGT's internal power system.

Just got the latest Marlin P. Jones catalog http://www.mpja.com and they have the Panasonic fans I mentioned above for $3.95, and a smaller one of the same style for $3.50....

That site's been mentioned before, specifically because of the fans. I bought a few, excellent service.
They don't tell you what shipping will be, but it's reasonable. About $5 for a box weighing a little over a pound. Straight UPS ground rates from what I can tell.
