Watercooling Pumps Guide Section v1.4 links (nonsticky)

:: Watercooling Pumps ::

The water cooling pump is most vital part of water cooling system, the very heart and soul of the water cooling loop. Most important part of the pump is reliability and other factors are performance, noise, size, and cost. Often pumps are bad because they are unreliable. The top pumps listed are all winners: quiet, reliable, and offer strong pump performance so you do not need to worry about flow rates, pump head pressure, power consumption or heat dump.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

:: Top Water Cooling Pumps ::

:: 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.

NOTE: DDC acronyms are DDC/DDC 2 or 3.1/3.2 or MCP 350/MCP355 or DDC/DDC+ or Pro/Ultra or 10 watt/18 watt
NOTE: Go to bottom to read Laing DDC Aftermarket Tops section for more info on DDC tops.
:: 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.
::
Laing D5 (Swiftech MCP655) :: USD $ 80 :: De facto pump for water cooling and sets the bar that other pumps are compared to. One of the best performing water cooling pumps is also quiet, ultra reliable, small, and uses about 18 watts. It has a speed controller that can adjust pump performance and noise level. Used with 7/16" & 1/2" tubing only.
::
Laing DDC-3.2 18W (MCP355) :: USD $ 70-75 :: Gets similar flow rates as D5 but smaller. Comes stock with 3/8” barbs and uses 3/8” tubing only. It has about same flow rate than DDC 3.1 with custom top but has higher power consumption and noise. --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

:: Honorable Mention Pumps ::

:: Aqua Computer Aquastream XT - USD $120-180 – There are several versions of this unique pump based on Eheim pump design but upgraded to run on DC, performance equal to D5 pump, and tons of gadgets including pump overclocking XD. This pump monitors flow rates, water temp, has fan speed control, pump speed control, various logging features, and software control that makes me drool. Problem is the expensive price tag $120-180+ and requirement of fitting adapters and fittings makes it almost expensive enough to upgrade a new vidcard, CPU, mobo, or Thermochill radiator. Uses USB to communicate to PC, you can upgrade from base version, and software is in Engrlish, OMG and you get what you pay for and that is a ton of features.
::
Alphacool AP1510 - USD $100 - This pump is about same size as D5, quiet @12V and comparable in pump performance to stock DDC 3.2 but slightly behind the Laing D5. Unit comes with voltage converter that makes the package bigger but allows change voltages of 12V, 15V, 18V, 21V, and 24V that will increase pump performance beyond D5 or any DDC top.
:: AquaXtreme 50Z-DC12 - USD $75 - Can be used with different fittings with sized barbs from ¼” to ½”. It is noisier than Laing D5, smaller size than D5, and similar performance as stock DDC 3.2. Uses about 8 watts so actually has performance better than Laing D5.
::
Iwaki RD 20 / RD 30 - USD $200 - A large 24V DC pump that requires an external PSU that should provide optimal flow rates. Expensive price tag of $200+ though but should last a lifetime.
*) Danger Den CPX-PRO:: USD $ 55 :: The bigger brother of Danderden budget CPX-1 and possible future top pump choice when available. Pump performance is better than stock DDC 3.2 and similar to D5. Size is about same as Laing D5 and quiet as DDC 3.1. This pump comes G ¼” threading and allows interchangeable barbs. Comes with 3 pin fan header for RPM sensor. Has moderate power consumption @ 15W. Best part of the pump is the cost, perfect for budget builder. Also comes with G 1/4” Bitspower barbs (wonder where it comes from….)
*)
Sanso 12V PDH 054 :: USD unknown :: This pump I bet few people have heard of. This thing is similar to Swiftech MCP 600
in design but is on steroids. It is getting on average .4-.5 GPM more than D5/MCP655. I don’t have much info on noise level or reliability but read the links to the review at bottom of pump section to get more info. It is hardly available in US.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

:: Budget Pumps ::

Danger Den CPX-PRO
:: USD $ 55 :: The bigger brother of Danderden budget CPX-1. Pump performance is better than stock DDC 3.2, DDC 3.1 with custom top, and similar to Laing D5. Size is about same as Laing D5 and quiet as DDC 3.1. This pump comes with G ¼” threads, Bitspower metal fittings, and can be used with different tubing. Has a 3 pin fan header for RPM sensor. Has moderate power consumption @ 15W. Best part of the pump is the cost, perfect for budget builder.
::
Alphacool AP700 :: USD $ 50 :: AP700 is smaller brother of Alphacool AP1510 that uses a lower 8 watts, has 3 year guarantee so it must be reliable, and has G ¼” threads that aren’t removable. It is silent and similar to dB-1 in terms of performance.
:: Swiftech Apogee Drive 350 Pump / CPU combo :: USD $ 85-100 :: Integrated DDC pump with Apogee waterblock makes this a great deal in a small, quiet, and easy to setup package. Pump and cooling performance is not top end but this not built for that.
::
D-Tek dB-1 / DD CPX1 :: USD $ 45 :: Small and very quiet pump good enough for CPU and GPU loops depending on parts that can used. Has G ¼” thread allowing interchangeable barbs but has good reliability. Performance and flow rates are lower than published. DDC pumps and CPX – Pro are better buys.
:: Swiftech MCP655-B :: USD $ 70-75 :: Basically a MCP 655 @setting 4, RPM sensor wire like DDC, and all the original D5 qualities.
:: Laing DDC-3.2 18W (MCP355) :: USD $ 75 :: Gets similar flow rates as D5 but smaller. Comes stock with 3/8” barbs
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

:: Laing DDC Aftermarket Tops ::

There are several aftermarket tops for DDC series pumps that improve the DDC pumps in two ways. First, these tops allow interchanging different types of barbs and barb sizes for ¼” to ½” tubing instead of being restricted to the stock 3/8” ID. Second, they can also improve pump performance by using a straight top inlet and eliminating the 90 degree bend on the stock top. This vastly improves flow rates of DDC pump series by 30-50%.

NOTE: So what is the catch? There have been several DDC revisions that have changed the impeller and top dimensions. The caveat these tops are not all the same and certain tops are designed specifically for either older DDC 350/355 series. Mismatching tops designed for older DDC models with newer DDDC pumps can and will increase failure rates. Example is Alpacool tops and older orange impeller DDC 2/355/Ultras. Even though this occurs in small percentage (repeat small) it will happen repeatedly. Others won’t cause failure but are not performance optimized for newer tops. If you plan to use a top do some research and reading and look at the DDC tops reviews at the bottom of this section.


:: Alphacool Clear Acrylic Top Multi inlet setups but has problems with orange 355/Ultra DDC versions
:: Alphacool Top Water Tank RES attachment for Alphacool Top. Really reduces performance and pointless having a DDC top.
:: Alphacool DDC Dual Hardwareluxx Edition Use with two DDC pumps.
::OCLabs XPTopTop inlet setup that is very small, UV blue, above average performance, but barbs are a worry.
:: XSPC Clear Acrylic Top Top inlet setup that is one of the top performing tops.

:: AC pumps ::


I no
longer recommend these but they are serviceable pumps. AC pumps often require a $10 relay to work in a PC water cooling system. These pumps are pretty reliable running 24/7 and require an impeller replacement once they start getting noisy.

:: 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.


:: Hydor L20 :: L30 :: L35 pumps :: They are similar to Eheim pumps but smaller with slightly higher performance than eheim but not as rock solid reliable. Hydor have some quirks but can be bought very cheap and replacement parts like the L35 impeller are available in USA or UK.
:: Hydor L20s are quiet and L30s are known to vibrate and hum that is noticeable in a PC case.
:: L35 or L30/L35 impeller hybrid offers considerable more performance than Eheim pumps and more reliable due to better impeller and same noise level as L30.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Dishonorable Mention List

These are pumps you shouldn’t consider for several reasons mainly because they suck.
They get reduced font to save space

:: Laing D4/ MCP650 - Not a bad pump but is noisier/whinier version of D5 with lower flow rates. It’s like the uglier sister you have to date being a wingman.
:: CSP-MAG Pump - Pump with known history of problems ranging from ticks, random non starts, and random failures. Older brother the CSP 750 was even worse. Don’t touch this one.
:: Thermaltake Pumps
- A weak pump that I’ve read with some failures after 6 months, leaks from the pump/res, reduced performance, or cracks in the RES. Pee shooter or super soaker for kids. Read Newegg.com customer reviews.
:: Gigabtye Pumps - Read above in Thermaltake for same problems and in Newegg.com customer reviews.
:: Via Aqua 300 - Considered an option because it is cheap and a certain mod makes them quiet. These pumps also die or leaks suddenly. Design is similar to AC pump like Eheim and Hydor which are better investments.
:: MAG 3-5 pumps - Same as Aqua 300 but this pump has awesome performance but leaks, has cracks in the housing, and failures that knocked it off recommendation status a long time ago.

Dishonorable Mention List

These are pumps you shouldn’t consider for several reasons mainly because they suck.
They get reduced font to save space

:: Laing D4/ MCP650 - Not a bad pump but is noisier/whinier version of D5 with lower flow rates. It’s like the uglier sister you have to date being a wingman.
:: CSP-MAG Pump - Pump with known history of problems ranging from ticks, random non starts, and random failures. Older brother the CSP 750 was even worse. Don’t touch this one.
:: Thermaltake Pumps
- A weak pump that I’ve read with some failures after 6 months, leaks from the pump/res, reduced performance, or cracks in the RES. Pee shooter or super soaker for kids. Read Newegg.com customer reviews.
:: Gigabtye Pumps - Read above in Thermaltake for same problems and in Newegg.com customer reviews.
:: Via Aqua 300 - Considered an option because it is cheap and a certain mod makes them quiet. These pumps also die or leaks suddenly. Design is similar to AC pump like Eheim and Hydor which are better investments.
:: MAG 3-5 pumps - Same as Aqua 300 but this pump has awesome performance but leaks, has cracks in the housing, and failures that knocked it off recommendation status a long time ago.
