Need Watercooling

Hey all, I’m new to watercooling and need help. My temps are too high for my liking using air and the only way to go would be watercooling.

Current Setup:
Intel Core 2 Q6600 @ 2.40GHz (1066FSB) (Not OC’d) Socket 775 LGA
Gigabyte GA-P35-DS3L Intel P35 (Socket 775) (rev. 2.0)
4 GB Platinum Revision 2 XTC PC2-6400C4 Dual Channel
StealthXStream 600w Power Supply

Processer cooled by:
Arctic Cooling Freezer XTREME Rev.2

Antec Nine Hundred Two

Avg. Idle temps = 40, 35, 34, 39
Full load Temps = 72, 68, 67, 71

These temps are without the q6600 being overclocked, and would like them to be alot lower before I overclock.

As I said I’m a total noob and have no idea what I need or how to go about building a watercooled system. My budged is around £150 ($247).

I’ve had a look and seen full kits like the Zalman RESERATOR 1 V2 or the Thermaltake Bigwater 770, but have no idea if they are any good, upgradeable or worth the money. Or do I start from scratch and build a custom system (but I have no idea where to start or what I need).

I would like to mainly cool the CPU, but i would love to be able to upgradeand have the option to cool everything

Any help would be very very helpful

  1. Before considering watercooling:

    1) Read Conumdrum's sticky at the top of this forum, and I mean READ everything. All the guides and links he has are invaluable. READ them all carefully. Then check out his links to skinneelabs ratings, where you will find a head-to-head comparison of several different 120.3 radiators. Depending on your GPU you may or may not need that much cooling, but now you know approximately how much heat they can dissipate and what fan speeds you will need.

    2) Before you spend hundreds (yes hundreds!) of dollars on a good watercooling system, are you sure you can't get the temps you need with air. You have a good case, the Antec 900 should give you plenty of internal airflow. Your Heat Sink is NOT a performance heatsink, it is designed for low-noise operation.

    From this review (

    In short, your cooler is pretty poor... very quiet, better than a stock cooler, but not a great performer...

    Before you drop hundreds of dollars into water cooling, there are many cheaper ways to a increase your cooling performance:

    FREE: Make sure you case is in a relatively open-air environment. If it is inside a cabinet or closed space, it will not be able to get good airflow, and your performance will suffer

    $15-$25: Swap out a better fan on your existing heatsink. The fan it comes with ranges from 600 - 1500 RPM (which is rather slow) and pushes 35.7 CFM, which isn't very much. Once again, this heatsink is designed for low-noise operation, not performance cooling. I am hoping that it is a standard 120 x 120 x 25 mm fan, but before you order a replacement fan, please please please double-check the existing fan's thickness. If it is a standard 120x120x25, then something like this Delta AFC1212D would be a good choice for pure performance as it pushes nearly three times the amount of air (but it will be loud). Other fans may run quieter, and still push respectable amounts of air. Just remember to measure the thickness of the existing fan first, and then remember to get a 120mm "PWM" fan.

    $40-$65: Get a whole new heatsink designed for better performance. See this website for reviews: It is a little out-dated, but it is an excellent place to start your search.

    If all of these won't work, or if you truly are looking for a silent system, only then you should consider watercooling. But READ Conumdrum's sticky first!
  2. nofun. Amazing excellent input. Can I please ask you to join us at OC Forums and look me up? Be nice to see your input at a more invloved forum. I'm Conumdrum there too.

    Your talent and great writing style is being wasted here at Toms.
  3. Thanks nofun for the quick response, I didn’t realise that the stock fan on the freezerXtreme was so poor.
    Off to read Conumdrum's sticky
  4. I’ve done some research and created a mini list of what i think could be a good start in the world of wc. I know it’s all from one site but I just want to put it up and ask advice before I spend endless time on the net searching for cheaper prices.

    Please let me know if you know of cheaper bits or better ones, also if i have missed anything out...

    I found this on google and really like the look of it, its so clean and minimal

    If anyone knows the parts used can you let me know.

    Or should I go back to getting the Zalman Reserator1 v2, or the WCUK Xtreme 120 Watercooling Kit ( )??

  5. The res/pump is kinda weak but enough for a CPU only loop.

    The Zalman is junk.

    A 240 rad is enough, The GT stealth is an OLD design and not near as good.
    DON'T need any temp sensors or flow meters. Just monitor your CPU temps.

    Keep it simple.

    The WCUK rad isn't big enough, great pump/res with that kit tho.

    Use Deinozed water and some silver wire as your liquid, don't need anthing else.

    What am i looking for in the spec? is it the size of the res or the Lph of the pump/

  7. The spec would be enough for your loop. Depends on your loop.

    You need a min of one GPM to two GPM per loop when all the hose and restrictions come into play. It's got a lot to do with head pressure too, weak head and it can't push past the restrictions.

    The res is ONLY to hold water.

    The pump/res you listed is not of the best quality, GPM/Head. Thats all. Higher failure rates etc.
