[GHz]

I regeistered here awhile ago when I was originally planning on watercooling my CPU, but unfortunately, then, I ran out of money to get my water cooling system. Went on a spending spree with hardware and didn't put any money aside for water cooling.

Well finally, with my last upgrade, I decided to get the water cooling stuff first then get my hardware. After putting together my system the first thing I noticed was that my CPU temp was kinda high, considering that I am water cooling my CPU. I am currently running a P4 NW 2GHz @ 2.5GHz @ 1.75V BIOS/1.68V-1.71V actual. My idle temps stays around 41C and under stress goes up to 45C. The ambient temperature in my case, according to my Digital Doc 5, is around 25C. This is my current water cooling step

DangerDen Maze2 P4 Skt478 Waterblock
Black Ice Xtreme Radiator w/ Sunon 108CFM 120mm Fan
DTek Customs Reservoir w/ 144GPH Rio Pump
All fittings are 1/2" with a T-line between the radiator and the waterblock.

I ran the thing for a full day with the pump in a bucket of water to make sure everything was bleed before installing it in my system. Could my water pump be the problem. I was thinking of buying one of those ViaAqua 370GPH Pumps I saw in a thread earlier and on the homepage hoping that faster water flow would help decrease my temperature. The reason I bought water cooling in the first place was for lower temperature leading to better overclocking and I was expecting much lower temps than what I am seeing now.

I also noticed something weird in my system. I noticed that the water level in the filler tube would dramatically decrease after about a week of running. I would usually fill the water level in the filler tube to about an inch from the top and cap the tube with a copper cap and tape it with duct tape. When I would check my system a week later the water level dropped a good 6 inches. I would refill it and a week later the water level would again drop. Now I know that you can lose water through evaporation, but that much water with the top capped and taped?

As you may already know, if you made it this far after all my ranting, is that I am a newbie to this stuff and would appreciate any help you can give me. Right now I am seriously considering buying a stronger pump hoping that I will see significantly better temperatures than I am getting now. Thanks.

(EDIT: I forgot to add, incase you wanted to know, at default speed and voltage of my CPU my idle temp was around 39C. I thought with water cooling and the radiator I have I would have gotten no more than 5C to 8C above ambient temperature.)
