Voltage control to pump?

Ok, I bought this pump Danger Den DDC-12V from you a few months ago and just installed it a few days ago. My question is, how would I go about regulating the voltage to the pump. There's a molex contecter and a 3 pin fan conection on the pump wiring. I have the 3 pin fan connector plugfged directly to the mobo. Not sure if it can be regulated from off of the motherboard. What are your suggestion on feeding the pump more volts? I just believe that the flowrate of the pump is a little slow and would like to speed it up. My system is running a bit hot for a water cooled system. Right now at idle it's at 43c/109f. Any help with this would be greatly appreciated. Thanks.

Well, you won't be able to do it with your PC power supply you'll need one that can supply more than 12V. I don't recommend doing that though, unless you want to shorten the life of your pump. I recall someone overvolting a DC waterpump and having it die an hour later.
 
Ok, so what can I do to lower the temps on the cpu? Before I installed the block, I lapped it pretty good. I amde sure I added Arctic Sliver and that the block is nice and snug. I was assuming that it may have been the flow rate from the pump causing the high temps. I also have a 120mm radiator sandwhiched between 2 120mm fans. Think a dual or triple 120mm rad would help witht he cooling?
 
[em]Heat I have just the solution for you! You want more flow with the laing DDC, well you are in luck! I have a way for you to increase the flow of your pump by *gasp* 70%, I kid you not. A very simple modification to the pump can greatly increase your flow at a loss of zero headpressure and gain of zero noise.

Thankx buddy. That looks like a really cool mod I think I'll have to try that out. Nice find.
