i will post more info as soon as i know it.

Sounds good. I also found a video on Youtube of some random dude by the name of Pascal speaking with Dazmode about the new Eisberg 2. You may want to go check this guy out, I think he's trying to say that he's YOU! Hahaha

For those that would like some more info on this Dazmode video...

Haha, I figured it was you. In the video though, do you happen to remember what voltages you ran both of the Eisbergs at?

Goddammit, I spoke too soon..

Pump didn't start when I turned on my pc this morning. molex 5v..

I was wandering around the house making coffee, and my pc was bluescreening and restarting repeatedly. I Knew straight away it was the pump. The pump itself was cold but the plate on the back of the mobo behind the cpu was a little warm.

I guess it's back to the noisy 7v option until I can afford a new pump.. :-(

What I'd like to do, ideally, would be to make an additional connection to the pump (as well as the 5v molex) from the fan header just to give it an extra boost when it needs it, ie on startup mainly.

My electronics skills are a little rusty but I'm thinking a diode to stop the flow back to the fan header, and a resistor (there's always a resistor there, right?). That way I'd still be able to control the speed of the pump, having speedfan, or the bios ramp up the speed without having all the wattage through the motherboard fan header.

Anybody electronics people think this is viable? any recommendations? Or is the idea just plain mad? :-)

I would not advise doing this
What I would do is add a switch, where you could have it on 12v as you start your system up, and later switch it over to 5v mode if so desired.
This could be made very easily. A 7/5 switch could also be made, but would be a bit more complicated.

Yea I thought about a switch alright but I disregarded it as I know I'd forget to switch it back after I turn the computer off!

Then again it may be possible to make an automatic switch that runs off a fan header, to switch between the molex to power sources. It would involve a transistor if I remember correctly. and would be safer too..

Could also buy something like this fairly handy, but there's no fun in that.. :-)

So in my searching I found this:

http://freeweb.siol.net/jerman55/HP/fanStuff1b.htm

Seems to be exactly what I'm after to give the pump a boost at startup, I'm hoping the diagram on the bottom of the page might work. I think I have the components lying around too..

Sure, I took a quick look and it should work. just make sure the components you use are rated for the current that the pump will be needing.
Fans are usually 0.2-0.3A, the pump will be wanting five times that, if not more (if the pump is in fact 23w@12v). So be very cautious.

I´ve started running my pump at static 7v, the flow I was getting through my two rads and gpu-block was not good enough at 5v, as I got a delta of 5-8 degrees C in GPU and CPU temps from switching up to 7v.
The high-pitch whine is killing me though, and I can´t ever have my apartment quiet anymore.
As my previous adapter was a little short, had solder joints on every cable, and a very flimsy molex connector,since it was mostly made as a test.
I modded the included adapter by removing one pin from the 12v connector and adding it as my tach-sense on the 7v (to make sure I didn´t bend the pin, I carefully cut open the whole connector) then removing both 12v wires from the molex-side. Soldered a 3-pin connector to be connected to the motherboard and added some random sleeving.
Much better. And more reliable.




Again, 7v isn´t quiet enough, so I´m getting a Phobya DC12-400 and a reservoir added to my loop.
I can pretty much afford the pump, and the res right now. But I don´t have the cash for a decent CPU block at the moment.
Has anyone ran the Eisberg just as a block with the pump off, using an external pump? If so how does it perform?


@AT-Pascal, I got my stuff through AquaTuning, I just thought I should ask. Since I got my Eisberg in a kit and will be wanting to keep the included rad (scraped some paint off the fittings, and cut and re-used one of the anti-kink springs)
Would it be even worth it for me to contact AT to return only the Eisberg main-unit? Maybe for credit towards getting an different CPU-block? Or will they be firm on me having to return the entire package? Or should I contact Alphacool? Or am I boned and will just have to eat the cost:D?
