Watercooling setup running hot

ok i have the aquarius III external liquid cooling system for a 3.4 ghz p4 processor on an intel 925 board with 1gb ddr2 and a geforce 8800gt video card with a wd raptor hard drive. I hooked up all necessary parts and filled up the water bottle the system came with twice. once with a mixture of cooling that the system came with (about half the bottle) and the 2nd time just using water b/c i saw that the system had a low level so i just added water. I dont know how long it takes to cool down the whole system but i had it on for 10 mins and was watching the temps on inel active monitor and the cpu was a steady 37 deg and zone 1 was 40 and zone to 48 deg and both were still rising so i just shutdown. When i started the comp they were much lower. these are basically the same temps i had w/o watercooling so i know that something is up. I'm just afraid of blowing something being i never messed with watercooling. i tried to understand the front panels on the system but it still not helping the problem of the comp gettting hotter and hotter. also in active monitor it said the processor fan was off or not working with a red light. i know why it says that but cant i disable it, or it really dosnt matter.

A couple of things after reading your post:

A CPU temp of ONLY!! 37C is excellent for a P4 Prescott 3.4!

Lowering Zone temps is all about good case air flow, nothing to do with the water cooling as the sensors are board surface mounted.

Lastly the TT Aquarius was never designed as a performance water cooling kit, it is primarily aimed at users who want to lower noise levels, infact in this review the Aquarius III unit is beaten on performance by an old thermalright SLK800 air cooler (admitedly with a powerful fan fitted)

Remember P4's have thermal throttling built in! so just reduce performance (as thus generated heat) when they reach a set temp.
This is a safegaurd to prevent damage.



Baring in mind that a P4 has thermal protection and that it is perfectly safe to allow temps to rise to 60C without any stability issues: run properly and report back definitive temp readings.

Thanx that helped me understand a few things i was not aware of. 1 last thing thouugh. if i dont put a fan blowing close to zone 1 and 2 and they stay hotter than with a fan is that necessarily a bad thing? b/c i want this thing quiet. that extra fan brings up extra noise. unless its necessary then i understand.
 
Well the 3.4 prescotts are a bit of a furnace and even though you are taking most of the heat from the CPU out of the case with this water cooling setup there are still other considerable sources of heat in there.
The 6800GT for one, the hard drive and chipset, all are heating up the cases interior.
Good air flow through the case is important, front lower to back top, remember the bigger the fans the quieter for a given CFM rating so a couple of 120mm fans is ideal if you have the space otherwise the biggest the mounts will allow.
Heat sensitive fans like the Vantec Stealth are a good idea to keep noise levels low, they will only spin as fast as needed depending on temp.
