Experience: 3 Years

excellent pump


still working great for 3 years
this is a great pump, but you need to buy fitting for your own buid.

Experience: 1 Years


*Great performance
*Quiet at certain speeds (vibrates my case at others)
*Runs cooler than the DDC pump I was using before
*Somewhat large
Very good pump with speed control. I highly recommend the speed control version so you can tune it to get the best cooling/acoustics balance for your system.

Experience: 5 Weeks


Quiet. Powerful flow. Nice speed control for purging initial air locks and bubbles. Tends to foam on high speed.Whisper quiet on low settings
Only 1 degree difference in temps with speed dial 1-5 (max). Really worth $10 more for speed control? Large aware
Love this pump.......solid and well built to fit 5/8 tubing over connector, when tubing soaked in boiling water for 5 mins. Very quiet and powerful flow, even on low setting. Only challenge is finding space for this big pump....Love it

Experience: 3 Years


Quiet on most settings.
Nice pressure.
Gets a lil high pitched at setting 4 or higher.
Attachment sections are unthreaded and a lil big. (Heat your tube up!)
I've been using this pump in my loop for almost 4 years now and its a die hard lil pump. If i ever need a new pump, or a second pump, I will prolly just get another one of these. Would be nice if it had standard g1/4 fittings or something but ah well.

Experience: 1 Weeks


Pumps water (haha)
Expensive compared to others
Rather large
Worked well in my build and I can see the liquid moving very quickly, I only required one pump for my build which is good because this thing is pretty damn big, but I know it will last for years. So far I am happy with it.

Experience: 8 Years


-8 years, still going strong!
-quieter than the mcp35x(has no whine either)
-Pump can cbe used in multiple housing
-Price(but you get what you pay for
Wow this pump is amazing, bought my first one in 2005 and its still going strong. I have always used swiftech hydrax though and that probably has something to do with it. Its no marketing trick, these babies will last 50000 hours of use. Dont let the price sway you, these are worth every penny.

Experience: 1 Years


very reliable pump. adjustable speed
not free
the beast of watercooling pumps. much larger than ddc but if you have the room you will be happy with this pump.can dial down speed quiet at #3 speed setting

Experience: 6 Days


- Silent
- Ultra powerful
- Did I mention silent ?
- Variable speed
- Silent. :)
- Barb directions (one from the top, one going to the side) makes placing this pump in your case more challenging than the MPC35X.
Just got this pump, installation is a breeze thanks to a super sticky vibration absorbing pad included with the kit. I was astonished by the near zero whine this pumps makes. It's virtually silent, still pushes water in my loop with very good force.

Pushing to a Swiftech Apogee HD, XSPC RX240 Rad, 2 Koolance GPU-220 blocks and a Swiftech SLI bridge with plenty of push still left getting into the Swiftech micro Rev2 res. Using 1/2 ID tubing from PrimoFlex.

My load temps all stock clocks from my i5 2500K and SLI GTX670 are 50/52 degrees at full load for CPU using AIDA64 with GPUs around 60 degrees each card. CPU is 7 degrees cooler that my old Thermaltake Bigwater kit, and GPUs are a whooping 20 degrees cooler than stock air cooling (keep in mind SLI with reference boards gets very hot...) with ambient temp being 25 degrees.
All pretty much near silent even at full load, with only 2 Noctua NF12 PWM fans on the rad + PSU fan (2x Noctua fans controlled by Mainboard are at 800 rpm for these temps).

Highly recommended.

Experience: 9 Months


Low noise
Low vibration
cannot change barbs
This is an excellent pump. Before purchasing it I was worried it would be too loud, but if you mount it properly this pump makes virtually no noise. Unfortunately there is no way you can change the fittings on this pump, so you are stuck with plastic. This hasn't really been an issue for me however.

Experience: 30 Days


- Powerful
- Reliable
- Adjustable Speed
High qaulity, long lasting, powerful and Adjustable Speed .. What more could you ask for in a liquid cooling pump. Great pump and only a few dollars more than the version without the speed adjustment.
