I'm fed up with the really noisy fans in my PC - they're driving me insane. I've had a look at a Water Cooling Kit available from Maplins, with the following equipment:

2 x Waterblocks
1 x thermal paste
9ft of ¼" silicon tubing
1 x Fill jug
4 x Different Mounting Clips
1 x Slot 1/A adaptor
3 x Slot and Socket hold down devices
1 x P4 device
1 x 12v Pump/Res
1 x Box full of hose clamps/screws.

I have no idea what this means for the welfare of my PC once installed, but I need to know, for those who've used or know more about water cooling, if the water tank/reservoir required is relatively small (ie. fits into a small room), and where the coolers will be installed ie. on the CPU, GPU, but is there a need for anywhere else?

I'm asking this as the two additional fans I have on the case produce the loudest noise, and I want to get rid of these as well.

Finally, a thing about Peltier devices - I've heard about it can channel heat so that it's very hot on one side, and cool on the other - where does this heat go without boiling the PC - would a water cooler be a good thing to use next to the Peltier device?

I hope someone can help.

You know what, I'm actually confused again.

lol, no, that would be silicon suicide if I had the panel on, which I want :-)

My current setup:

1x26cfm 19dcb Papst intake
1x26cfm 36dcb YS-TECH exhaust
1x47cfm 34.2dcb YS-TECH exhaust at the top (desabled)
1x47cfm 34.2dcb YS-TECH heatsink fan (debating replacing with marginally quieter Papst)

also 1xUnknown exhaust from PSU (may replace with Papst)

Hardware: XP2000 (141mhz FSB, 12.5x multiplier), ThermalRight AX7 heatsink, overclocked Gainward Ti500 and a Maxtor 40gb HDD which tends to get a bit warm.

The entire setup runs at 52c CPU/32c System, which obviously gives me room to play with.

When I get my baybus I'll have it set up like this:

12/7 - CPU
12/7 - Exhaust
12/7/0 - Top exhaust
12/0 - Cold cathode

The intake I probably just won't attach as it's literally silent.

Congratulations to anyone who understood that :-)

Just been reading all the posts here in detail.

So TBN, in your plan, are you going to forget about any case fans altogether, using a bigger fan for the heatsink instead, hoping that would providde ample air circulation for the rest of the case?

And I'm still having trouble finding out which component is the loudest in my computer... is the chassis fan, the hard drive, PSU fan... I don't know!!!

Really? And I thought heatsinks were made to cool hot CPUs - not that you can hear the sound of a CPU fan over the rest of the noise generated by your average PC case.

No but it is good for what it is made for "silence".

Yes, as I said, but as good as it is it still relies on the traditional principle of "heatsink sucks heat away from CPU, fans provide the airflow to move it away". The only difference being that it can use a bigger fan, which shifts more cfm. It's exactly the same as sticking a 120mm fan on top of your standard heatsink, except you can't do that. Well, you can, but I don't fancy buying from Australia. My plan is to get a large 80cfm 120m Papst fan that puts out 24dcb and 7v it, which will get me quieter than the Zalman, combined with the superior quality of my current heatsink, without the faff of having anything attached to the chassis.

AMD_MAN, the Zalman isn't a particularly good heatsink because the cooling it provides isn't as good as some of the other models on the market for less money.

You can try and fit a 120mm fan to your heatsink just "bodge" it.

Turbo why do you say the zalmans are not good heatsinks, they are great, they come with a silent 90mm fan but you can use a bigger 120mm fan running at 5 or 7 volts (nearly silent) to push more CFM onto the Zalmans, try looking at some reveiws of them!.

Deltajava i would definatly advise you againt useing a peltier, more hassle than they are worth.

turbo the problem with "just sticking a quieter fan on yout heatsink" will mean less CFM of air running over the current heatsink thus the heatsink getting hotter and making the cpu hotter, if anything a higher power fan is the thing that will cool the cpu heatsink better.

If you are going to try water cooling i would go for a setup with good parts, most importantly a good Pump Ehiem's are best by far.

a res isnt needed as long as you have a bleed pipe, and a rad is needed.

There are loads if great places on line to buy this stuff.

In my experience it's the fan you schwonk on top that generates the noise, not the heatsink. I know the Zalman uses a quiet fan and different setup, but if you just stick a quieter fan on your heatsink there's no difference...

Zalman's are very quiet, and resonably good for cooling. I use a silent version of the CoolerMaster Heatsink, and it's very good, CPU temps are reasonable and it's almost silent. Top notch.
