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.

Personally, I wouldnt buy from Maplins, I'd buy from a proper overclocking shop, you'll get better quality stuff, possibly cheaper, and the staff will be able to advise you better than the teenagers who work in Maplins....

Peltiers are used with a watercooling kit or something even stronger, but I REALLY wouldnt recommend a peltier unless you know exactly what your doing, the hot side produces massive problems, such as condensation. Also, that kit doesn't have a radiator, so wouldnt cool the peltier well enough, so you'd end up melting something.

The only parts of the PC that need cooling really are the CPU and the GPU, although some motherboard northbridges run very hot, so consider that, or adding a larger heatsink.

Your also going to need to keep the water cool somehow, and without a radiator that may be difficult and will probably need case fans anyway.

Water Cooling is safe, and a good way to keep your PC cool, but it has to be done right, so consider other things first, and use water cooling as a last resort. There are a wide variety of silent fans and stuff out there to make your PC quieter, in particular, try http://www.quietpc.com/ or Papst fans available from www.overclockers.co.uk

IMHO you have to be pretty hardcore or desperate to want water cooling, and I garauntee it's not going to help you. That case still needs ventillation, water cooling or no, and it's often items such as case fans/hdds/PSUs/GPUs/CD-ROMs that cause noise. If I stop my HSF, I can't hear any difference over the noise of the PSU, GPU, or in particular my intake fan. That's why I'm in the process fo replacing the intake and installing an exhaust, which should both be silent. I may replace my PSU, but I've realised the noise from that depends on internal temperature, and lowering that (with the silent fans) will reduce the noise from it. To be truly honest I think water cooling is a thorough waste of money to anyone who isn't a serious overclocker.

I had water cooling in my system for ages and i couldnt fault it, i wish i hadnt got rid of it now as it was so quiet and great at cooling but a radiator is needed, also i am a serious overclocker so it helped me, i would say it was worth it but if you are not overclocking that much and the heat isnt that high then with the money you will spend on a water cooling kit you could get all round new heatsinks with low noise fans or go for the zalmon range of heatsinks they do these for cpu's, gpu's and northbridges and they work well and are basically silent, have a look at www.overclockers.co.uk.

IMHO??? Huh?

HSF - Do you mean high speed fan by that?

I have four fans at the mo - PSU, GPU, CPU and a case fan on the back. If I were to remove the latter, at replace it withan exhaust, as you say TBN, would there be no noticable difference in heat within the case?

Also, where do you get these exhausts?

By the way Turbonutter, doesn't an exhaust create quite a bit of noise like an intake fan?

HSF = HEATSINK AND FAN

One thing you have to make sure when putting case fans in and that is that you "exhaust" more air than you put in otherwise you will just be blowing hot air around your system, so 2 fans is better with one taking in and one exhausting out at the moment i have 4 case fans in my system, 1 80mm slowish intake fan in the bottom corner of my case, 1 80mm slowish fan in the rear corner of my case intakeing, 1 i have cut into the side panel of my case directly above my CPU HSF and then i have cut a hole in the top of my case for my 120mm highish speed papst fan exhausting and my cpu (P4 1.8 Nw running at 2.61ghz, 1.8 volts) is about 47 degrees under load, there are a few other things to take help with excessive heat, you can "LAP" your cpu Heatsink (this is a process in which you finely sand down the contact side of your heatsink thus making better contact with the cpu core, you can use better heat transfer paste, you can purchase a better Heatsink and fan, you can try and adapt an 80/120mm fan on your current heatsink and fan.

Also i have a Heatsink and fan you can have for £25 inc post and package just sitting around doing nothing it is for Athlons, it is called a cooler master heat pipe and is pretty good also have a look at them zalman heatsinks i told you about they are nearly quiet, go to overclockers.co.uk.

A fan at the back is an exhaust. Any fan. Just as long as it blows outwartds.
