( #1 )

First I would like to thank realredraider forums, Shane (HESmelaugh), EXS (sorta...), OCUK and a buncha other folks for all the testing and information gathering done. More than half of this guide is based off ricecrispis writeup guide on the EOC forums. The information within this WC guide is a cumulative set of info from multiple WC communities and from my personal experience. Different Experience will apply. Watercooling on the X58 and in general: - Beware of buying "Watercooling Kits"! - NEVER MIX METALS... heck just never buy anything with Aluminum. CPU Blocks: 1) HeatKiller Rev 3.0:: USD $ 65-80 ::Top performer and considered one of the best for I7. LC version has higher flow but slight lower performance. DONT forget to buy the backplate! 2) EK-Supreme LT :: USD $ 50 :: New revision of Supreme with better cooling performance, within 1C of of the top blocks and better flow rates. Great quality but square design lacks flair. 3) Swiftech Apogee XT :: $60 :: Block is quite restrictive and has high restriction. What makes this a winner is the further improved mounting gear, improved design, the ease of installation and beautiful aesthetics with great black and chrome look like the GTZ. Its also a tad cheaper. However, 2 of 3 samples I have seen had bad milling defects and the other last one, although not as bad, had milling problems as well. I would make a guess and say this was due to the more complex matrix and that the people milling the copper werent too experienced in such a complex mill yet. maybe future productions will yield better quality. 4) Swiftech GTZ :: $70 :: Block is more restrictive than GTX and has med/high restriction. What makes this a winneris the great mounting gear, improved backplate design, the ease of installation and beautiful aesthetics with great black and chrome look. 5) Enzotech Sapphire :: USD $30-50 :: Design is simple and offers a good balance of performance, flow rates, and value. GPU water Blocks: - This will obviously depend on your GPU. - I like legacy core blocks on GPUs as i can swap em out - I then use enzotech ramsinks and mosfet sinks Full Coverage GPU blocks 1) Heatkiller has probably the best full cover blocks 2) EK blocks would follow next since they do have problems sometimes. 3) Bits power blocks come in 3rd due to price and mediocare temp performance. GPU Core Blocks 1) MCW-60R - $40-$50 - imo the best core block out there due to constant support from swiftech 2) D-tek Fuzion GFX2 - $40-$50 - I used to like this, but seems to lack support. X58 motherboard Block: - the EK x58 Fullboard block is my only suggestion here. (Good price/great performance) Water Pumps: 1) Laing DDC 3.2 (MCP 355) with Custom Top:: USD $90-110 :: The DDC series pump are very popular known for having excellent pump performance, small size, reliability, and being nearly silent. The pump comes with 4 pin Molex for 12V power connection and 3 pin fan header when attached to mobo fans header that acts as a RPM sensor. This allows BIOS to monitor the pump RPM and shutoff when the pump stops spinning during failure. The stock top has 3/8” plastic barbs and uses only 3/8” tubing. The more powerful DDC 3.2 uses 18 watts, is a tad louder than DDC 3.1 and stock is comparable to Laing D5 in pump performance. With an aftermarket DDC top, performance increases even higher. 2) Laing DDC 3.1 with Aftermarket Top :: USD $90-110 :: The Laing DDC 3.1 is weaker version of DDC 3.2 and slightly more reliable than DDC 3.2, and quieter than both the DCC 3.2 and D5. The DDC 3.1 has low power consumption and uses only 8 watts and with a top has pump performance similar to Laing D5, stock DDC 3.2, and AquaXtreme 50-Z. 3) Eheim 1046 :: 1048 :: 1250 pumps :: These are extremely reliable AC pumps that can last up to 5-6 years or longer. They don’t die but gets noisier with time when impeller gets old and requires simple replacement. EMI can also be an issue but is unsubstantiated with some people run 5-6 years with these guys and no issues. Aqua Computers released Aquastream XT DC versions of Eheims that are more expensive, with increased performance, and unique add-ons like software control and monitoring. :: 1046 is extremely quiet but has low flow rates and not worth buying. :: Eheim 1048 has better performance than 1046 and barely any noiser. :: Eheim 1250 is much larger, known to vibrate and hum that is noticeable in a PC case, and gets decent flow rates. :: Don’t get the 1260. Radiators: << 120.1 RAD >> Handle about 100-200 watt loops @ 50-90 CFM. Cool about one major component. Enough for overclocked QUAD but might require louder high CFM fans. Good as best air cooling but with more noise. Not recommended overall. << 120.2 RAD >> Handle up to 200-400 watt loops @ 80-150 total CFM. Cool 2 to 3 major components. Enough to cool an OC’ED CPU and GPU card, maybe overclocked CPU and stock SLI setup but with higher temps or requires higher CFM fans. <<120.3 RAD >> Handle up to 300-600 watt loops @ 120-240 total CFM. Cool three or more components. Enough to cool both overclocked CPU and SLI setup with some other parts. - NEVER get 120 rads. - Either get 240 or 360 Rads. - TFC, XSPC RX series, TC PA series are all good rads - For Big rads, dont waste your cash on a TFC monsta. - The Mora2 Pro rad is the best large rad, thats 120x9 (will need good pumps and flow rate) - Check and verify the radiator will fit properly inside your case or setup. Doesn’t matter how good, how expensive it is, or how it looks when it plain doesn’t fit. Double check the radiator dimensions and alignment before any modding. Having a cardboard cutout or mock box model helps determine proper clearances. - Watercooling radiators are so well designed and highly optimized that radiators of the same size group (ie 120.1, 120.2, 120.3) perform roughly the same. - Most rads are designed to perform within a certain fan CFM range so they perform better with low CFM, medium CFM fans, or high CFM fans. Matching the correct fans to radiator is the best way to squeeze another 1-2C in performance. - Want everything internal? Want the performance of a larger 120.3 radiator but have space for only 120.2 or 120.1 radiators? Then setup a build with a couple of RADs. This setup doesn’t perform as well as single larger radiator and also adds additional restriction requiring a powerful pump. - Heatercores don’t perform better than PC radiators, usually a bit worse. They offer average performance with unique Pros and Cons. - Don’t pick RADs with round tubes or aluminium radiators. Round tubes perform much worse, and AL rads present a high risk of corrosion. - The factors that differentiate radiator performance are radiator frontal size, thickness, FPI, restriction, and the fan used on the radiator. Tubing: :: Tygon R-3603 :: Tygon Antimicrobial Tubing AS6 :: Tygon R3400 :: Tygon A-60-G Norprene (Swiftech Norprene) :: Masterkleer :: Swiftech :: ClearFLEX :: Durelene (Cheaper than Masterkleer and Clearflex and just as good) :: Primochill (Tygon R1000) :: Feser Tube - FT - Active UV Hose - ID 1/2" - UV BLUE Why 7/16" and 3/8" are the better choices - Advantages of using 7/16" tubing instead of 1/2" - 7/16" fits on 1/2" barbs very tightly. It seals better on barbs than 1/2" tubing so it is less prone to leak. - It has tighter bend radius so it doesn’t kink as easily as 1/2" tubing. Using thicker walled 7/16" tubing allows even better turn radius - Smaller OD of 7/16" tubing makes it look slimmer, more appealing, blocks less airflow, and easier to setup. - Gets the same flow rates as ½” tubing. Flow rates are limited by restrictions caused by 1/2" barb, not the tubing which has the same diameter of 7/16” tubing. - Drawbacks of using 7/16" tubing - 7/16” is harder to install over ½” barbs. They are perfect for ½” hiflow metal barbs since the tubing slips on easier and off metal barbs. They are a tight fit over ½” plastic barbs. Even 1/2” tubing on ½” plastic barbs doesn’t just slip on or off easily. They are hard to install on perfect seal ½” metal barbs and harder on plastic barbs on D5/MCP 655 pump - This requires heating the 7/16” tubing ends in hot water, not boiling. I like to microwave hot water in a coffee mug. Once the tubing ends gets soft and rubbery, they are easier to install over the barbs. Using a blow dryer or heat gun on the tubing also works but hot water works easier. - Why and when to use 3/8" tubing - Smaller ID 3/8” tubing bends even easier than 7/16" tubing and so easy to setup. I don’t suggest using anything smaller than 3/8” because 3/8” tubing fits into anything. - If you have a small case, or tight on space then just use 3/8” tubing and keep it simple. If a recommended pump was chosen their is no need to worry about flow rates and forcing a setup with ½” or even 7/16” tubing - WC Tubing Review Links: :: Tubing Review - 18 Types of Tubing Reviewed by virtualrain @ virtualrain.blogspot.com :: The Impact of Tubing Sizes on Waterflow by Cathar @ XS forums :: Tygon Hose V Danger Den Hose by Coolmiester Paul @ coolercasesuk.co.uk forums Fittings: Not too long ago someone asked me about fittings and what they need. I found this a very hard question to answer. Depending on the loop/setup, different fittings will be required. Fittings are also pricey, in fact, you can spend more on fittings than you do on everything else. I will try to go over the different types of fittings to the best of my knowledge here. before I start, let me say that.... Bitspower is the downright best brand (imo) for fittings. If you are in the states you can order easily. For those in asia, you can drop their taiwan office an email with your order and they have stock of EVERYTHING. just make sure you know what you want and have everything ready. Prices will vary too. some are cheaper, some are pricier. They give bulk prices as well. Types of Fittings - barb type (only need to know ID of tube) - Angled Rotary barb (available in 45 and 90 bends) - Triple, double, single rotaries available - compression type (important to know both ID AND OD of tubing) - angled rotary compressions (available in 45 and 90 bends) - Triple, double, single rotaries available - extensions/reducers - G1/4 Extender - tube reduction fittings (honestly dont recommend even chaning tube size in loop) - D-plugs for SLI cards - G1/4 to G1/8 reduction fittings - Stop fittings - G1/4 stop fitting - Tube plug fittings - Tube sealing plug for easy draining (i.e. using T or Y blocks) - Adapters/couplers - T block/Y block/L block (these are useful in your loop to create a drain/fill point) - 1/4 NPSM to G1/4 adapter is needed for things like the MCW-60r gpu core blk - male to male, male to female, female to female adapters are available too - angle adapters in 45 and 90 bends. - angle rotaries in 45 and 90 bends in single, dual, or tri rotary. - General facts: 1) you can use a compression and a angled (rotary adapter) to make an angled compression 2) T-blocks with tube stop plugs are a great way to make a drain point. 3) when using a T-fitting, make sure that your drain/fill point is at the bottom of the T. Keeping the flow straight is best for all loops. 4) 2x 45 adapters to create a 90 bend has actually slightly less restriction than a 90-L bend. When purchasing fittings know what you need, The following is my personal recommendation for a list of fittings per loop. - 1x t-block - 1x tube stop plug - 4x 45-angled rotary adpater (or more depending on set up) - Extra O-rings for Compressions or barbs. - Compressions (or barbs) - Buy extra of these for the T block. - say you have a cpu/rad/restop loop, you will need 6 compressions. - if you add a T block, you will need 9 compressions. Coolants and additives: 1) Distilled water + .999 pure silver coil (bezel or wire) - Silver kill coil by iandh available at petrastech. - How to make your own silver kill coil by Xilikon 2) PT nuke copper or PHN 3) Swiftech Hydrx (or car antifreeze rofl) Here is a quote from Petra on the different PT Nukes ORIGINAL: Petra A simple explanation: The blue PT Nuke utilizes copper sulfate as its active ingredient. Now, the copper sulfate solution is somewhat acidic and can lower the pH of a poorly buffered coolant solution. As such, it is intended for use with water cooling systems that are also employing other coolant additives (like Pentosin and such). You can use it with straight distilled but it's not something that I usually recommend to people. If one were to use too much of the regular PT Nuke in a system containing both copper and aluminum parts, it's possible that the coolant's pH could be lowered outside the effective range of whatever anticorrosive you're using... which could lead to accelerated corrosion of the aluminum. The clear PT Nuke -PHN utilizes benzalkonium chloride as its active ingredient--a chemical that's used commonly in disinfectant pads, hospital sterilization solutions, and [in very low concentrations] as a preservative. This solution does not have an impact on coolant pH but is very easily neutralized by other chemicals. As a result, the PT Nuke -PHN is what I primarily recommend for those using straight distilled water as a coolant. Of course, another alternative would be to add a piece of 99.9% pure silver to your reservoir. How to assemble and test your loop: ORIGINAL: Mikotan "In order to get comfortable with their installation, cut a 3" piece of tubing and learn how to put it on a barb and clamp it. Better now than when it's in the PC. Exercise the clamps; open, close them a few times to make them smoother. For barbs, tighten down to finger tight and 1/4 to 1/2 turn more. Do not over tighten with a wrench; the o-ring can bulge and cause a leak. Boil sink water and let it cool 5 min. Pour into the radiator, filling it up and let it sit 10 minutes. Drain half of the water or so and shake it till your arms hurt…3-4 min like a crazy person. Drain into a clear container. Do the radiator dance again and again till the water coming out is clear and there is no gunk once the water settles. Then do it two more times. NOW and only now is your radiator 90% clean. No worries, the last 10% will come out in the next year or two when you redo your loop for maintenance. finally rinse with distilled water. Inspect your parts. Open the pump, look for gunk / packing material. Run sink water through the blocks, pump, hose. Drain as well as you can, but don't go crazy on draining every last drop. Inspect bottom of block. Don't forget to remove the plastic cover!! Inspect screws and holes, check they go together well first. Seen more than one bad screw broken in a bracket. Your radiator screws might also not work perfectly. DON’T put a screw through the radiator, seen this done more than once. Install blocks on parts. Take it slow, even remove to check TIM contact if you want. Install hose. Measure twice, cut once; make it a bit longer if you’re worried, you can always cut it shorter. Dry mount everything, and inspect all clamps etc. Take a walk, watch a movie. Then inspect it again. After that is done, it’s time to fill the system and test for leaks. DO NOT fill the system and turn the PC on. You want to make darn sure there aren’t any leaks before putting electricity through the parts on which the water loop is mounted. Before proceeding, put paper towels (or the absorbent material of your choice) underneath every potential leak point in the loop installed in/onto/near electrical components. This includes not only the tubing & barbs, but the blocks themselves. Once you do that, power on the PSU. The pump will begin to push the fluid through the loop. When the fluid before the pump is exhausted, turn it off. DO NOT RUN THE PUMP DRY! Fill the res/t-line up again and repeat. Do this until the amount of fluid before the pump remains constant. That indicates the loop is filled. As you will surely notice, filling the loop generates a significant amount of bubbles within the loop. These are easily dissipated. Simply let the loop run. The bubbles will be expelled from the liquid when it gets back to your res / t-line. Keep an eye on it for the first little bit as expelling the bubbles will lower the fluid reserve (replacing it with air). You'll need to top off the fluid at least once, potentially more if you're using a t-line setup and then once again when all bubbles have been purged. Eventually the liquid will be bubble-free. Generally this occurs sometime within 24 hours. Most bubbles will come out relatively quickly, but there will be stragglers that will work their way out of the loop eventually. Once the vast majority (99.9%) of the bubbles are gone, you’re fine to go ahead and run the loop on the system while the remainder work their way out. For testing purposes, it is necessary to run the filled loop for enough time to satisfy you there will be no leaks. This varies from person to person. If you’ve made it this far, you’re smart enough to know what is reasonable for you. I’ve heard anywhere from one hour to 24 hours." Thats a quote from an article i read a while back and copied into a textpad another thing i also put 2 rounds of paper towel on every barb. and seal them with electrical tape. this might be overkill... but youll thank me later if you have a leak. Ramsinks Installation Tips - Some ramsinks require extra work to install and are known to fall off repeatedly when not installed correctly. - The best but time and labor consuming method is removing thermal tapes and applying thermal adhesive or epoxy. This is not always required - Before applying ramsinks remove the video card and clean the DDR ram and other parts with some isopropyl alcohol and lintless pad. - Press down on the ramsinks for a minute or two when attaching to the ram. - The best but time and labor consuming method is removing thermal tapes and applying thermal adhesive or epoxy. - The ramsink thermal tape might require some heat to fully bond to the ram so run the video card under a benchmark or do some gaming. - Large single piece ramsinks and full coverage blocks might require TIM pads and grease so apply grease to to RAM and other IO components and place ramsink or Full Coverage block on video card and see if the Ram and block properly contact each other and leaves a TIM mark. (I dont believe one should ever restrict oneself from further reading and learning. Sure i wrote this guide to make the jump to Watercooling a tad easier for the folks here on the eVGA forums. Please do not forget this is just one guide/faq out of probably a thousand other guides out there that are just as informative and as useful with their own flavor of opinions and suggestions. Before i personally made my jump on DiY WC on heatercores years back i read a crap load of what little info that was shared back then. These days, there is an abundance of info, faqs/guides, reviews, thoughts, opinions, and many more. So read as much as you can, but read everything with a grain of salt. We are all human and we all make errors.) following are list of links that I believe everyone should at least have a look see.
