Hi everyone,again.I need your help and advise again to spend some money-or 'waste' it as my other half puts it!I am on the quest to upgrade my pc and I am looking at getting a water cooled system.I have looked at a number of options and have decided to opt for a kit.I have short listed my choices to the following two makes,Thermaltake CL-W0121 Big Water 760i Liquid Cooler compact.Swiftech H20-120 Compact System Cooling Kit.The reasons for my choice are based upon availability in UK,ease of fitting and cost.All the sites I have looked at say both are good but unfortunately I could not find anything comparing the two.I would be grateful if you could please share you views on these two products or if you could recommend something else.I am looking at upgrading tointel q6600 cpuasus striker motherboardnvidia 8800 gts.Looking forward to your suggestions on how should I 'waste' my money.Qas

As you can tell, I'm a HUGE fan of Koolance, but in your case I'd go with the BigWater. It's a good beginner setup, and has everything you'll need. It's not exactly a "high capacity" system, and won't handle any insane overclocks, but it'll get the job done if you're just looking for an entry level setup, it's perfect.

Do you realise that you can likely overclock your 6600 to 3.2 GHz with the stock heatsink/fan? That is what I've done - I actually run it at 3.0, but it was stable at 3.2.. hard to see why you would want to invest in watercooling...

What's your FSB running at with that though? Sure you CAN overclock it to 3.2, but can you do it at 24*C?

Nick, I'd be curious to hear what you think of the PC4-1026SL setup from Koolance, if I'm only going to run something like a QX6850 and a single 8800GTX on my next build. It appears you're running multiple radiators .... is that because you water-cooled a bunch of other stuff on the mobo too? I was thinking of just using the little clip-on fans for the heat pipe coolers.

I'm running with the standard 9x multiplier, so the FSB is happy.Granted, as you increase the ambient temperature, you may need to up the cooler.. So far everything runs just fine with my variable speed fans running at a quiet pace - at 21 degrees room temperature. Great CPU, the 6600 !

many thanks for your comments.I have done a little research myself and it seems that the thermaltake 760i is not very efficient for cpu over clocking.I searched ebay for koolance and came across this:Koolance Exos External Liquid Cooling System It's a brand new unit -but one of the 1st designs(2/3 yrs old)Would this be better option.Sadly all the koolance units in UK cost twice as much as they do in the States-the cheapest-exos sl- is about

The EXOS is a wicked unit. Like I said, it's no secret that I'm a Koolance fan, because they are BY FAR the most thurough and best quality maker of PC watercooling supplies out there. Check out www.koolance.com and see if you can't find a refurb one for cheaper.

go on crazypc.com theres lots of coolers there.
