I want to start water cooling my commodore G. Ive been looking at various cooling systems and decided to have a good look inside my system for space and stuff. Thing is, I noticed the CPU fan also seems to be cooling a radiator that hangs down from the PSU via 2 copper pipes. Is the PSU going to suffer if I remove the CPU fan and heatsink to put a waterblock on there? I still have a 250mm sidecase fan which might cool the PSU rad but my project aim is to watercool the CPU/GPU/Hardrives/Northbridge/Southbridge to eliminate the need for fans alltogether and have an ultraquiet and fast performing system (with a few overclocks ofcourse). Any info will be much appreciated as Im new to watercooling and want to try get it right. Im not sure , is it possible to achive a non-fan but cool system?

Can you posts some pics of the inside of your case? It would really help with a recommendation if I could see what kind of parts were being used. =]

//edit

Also, keep this in mind, because this is a mistake a lot of people make.

Watercooling will not eliminate the need for fans in your case. What it will do is provide superior cooling to the parts and components blocks contact, but will not do anything to lower the ambient temperature increases generated by everything else.

That said, There is no reason to ever, ever, cool your Hard drives or Southbridge with water blocks. When you try to cool those components along with everything else, you're running into a multi-loop scenario which will cost you hundreds more for little to no cooling benefit.

I would only ever warrant the cooling of CPU's, GPU's, and Northbridges (in instances of overclocked systems).

That said, in my system (check my spec sheet), I'm running blocks in my CPU, both my GPU's, and my Northbridge.

My Southbridge has a micro heatsink/fan combo, and my mosfet/vregs are cooled by heatsinks. I have four 120mm case fans, three 120mm radiator fans, and two 80mm case fans, just to keep the air fresh and moving, as well as greatly helping with over all cooling.

When talking about overclocking, and cooling in general, there is no such thing as over kill, because lower temps are better performance.

Water cooling, in relation to overclocking, removes one of the two primary factors from the clocking equation, the first being adequate cooling. The second is voltage regulation, which really, is the heart and essence of the craft.

And fill out your system specs too.

Thanks for your reply. OK I should have done this in my first thread. This is my system specs:

MB: ASUS P5N-E SLI
CPU: QuadCore Intel Core 2 Quad Q6600, 2400 MHz (9 x 267)
GPU: NVIDIA GeForco 8800 GTS 320mb
RAM: DIMM1: Corsair XMS2 CM2X1024-6400 Memory Speed DDR2-800 (400 MHz) X4
CHIPSET: North Bridge: nVIDIA nForce 650i SLI (C55)
South Bridge: nVIDIA nForce 430i (MCP51)
OS: Windows Vista Ultimate X64
Fans: 1 X Sidecase 250mm
1 X Front 120mm
1 X Rear 120mm
1 X CPU
1 X GPU
1 X PSu

I don't know whether its one of the fans in particular or all together but my system is very noisy. I can constantly hear the fans running which is becoming very annoying. I know I can eliminate the CPU and GPU fans with water cooling which might help my system run a little quieter. Yes I think the 250mm case fan is a must keep. As for the 120mm front hardrive fan, I was looking at a water cooling block for cooling the hardrive. I dont know how good these are maybe you might be able to tell me if their good or not and if they are good, can I eliminate the 120mm front fan. Will the 250mm sidecase fan be enough to draw fresh air into the case alone? The reason I mentioned the southbridge is because this particular ASUS motherboard Im using has no fan or heatsink on the southbridge. Any further input you can provide me will be much appreciated and respected. Thanks again, WEB.

If you want good cooling then the tuniq tower or TRUE are great. On either you can replace the fan or for the true you usually have to buy a fan. Just buy some good fans and your set.

If it is the fans just buy some with a low dba.

I want to watercool because I plan on overclocking this baby as much as I can. The fan noise is another reason I want to watercool but not the only one. Overclocking my system is becoming a big interest to me. Id like to try it and succeed with a powerful but stable system and this is why I think watercooling is so important for my project.

What case?

Try a Lian Li PC1000 case. I use a modified one for my cooling setup and it works great.

I think you're a litle confused. You have to use fans on the radiator. It kind of works like this..

Watercooling is: (Choose one line)
Expensive, Effective, Loud
Expensive, Ineffective, Quiet

It kind of works like horsepower and gas milage. You can't get 600 hp and 40 mpg, and you can't remove 600 watts of heat quietly.

You really should be looking at heat load, radiator efficiencies, pump flow rates and fan CFMs. Do the calculations. Yes, the bigger the rad the less air flow you need, but you still have to know how big and what CFMs you'll need with what water flow in order to remove the heat load you will have.

OK thanks for your reply. Have you any recommendations for me. Im looking at the Thermaltake Bigwater 760i as a starting point. Would you class this as Effective + Loud or Ineffective + quiet? Im also looking at the Koolance VID-280 for my 8800 GTS. Did you hear anything about the effectiveness of these?
