The C-Systems CSP750 Brushless DC Pump comes an assortment of accessories which include the following:
- 2 x 3/8" T Fittings
- 3 x 3/8" Right angled barbs
- 3 x 3/8" Barbs
- 5 x Adhestive pads
- 2 x Fan power cables
- 1 x Drilling template
The package received from C-Systems did not include any documentation but a quick visit to their website
provided links to both Word and PDF
reference guides. The steps for preparing the CSP750 are very straightforward and can be completed in
less than 10 minutes. All that is required is to insert any of the bundled fittings into both the inlet
and outlet ports. In this particular example I used a roll of Teflon tape to secure the barbs and make
them water tight.

To start performance tests, I assembled the following pieces of hardware to complete the system:
- ABIT NF7-S Rev 2.0 Motherboard
- AMD Athlon XP 2200+ CPU
- Albatron Gigi FX5900XTV 128MB Video Card
- 2 x 512MB Corsair XMS3200LL Pro Series Twinx Memory Kit
- 2 x Maxtor D740X-GL 60 GB Hard Drive (RAID 0)
- 1 x Maxtor DiamondMax 9 80 GB Hard Drive
- Promise FastTrack TX2000 ATA-133 w/ RAID
- D-Link DFE-530TX NIC Card
- Pioneer 106S 16X DVD IDE
- Lite-On LTR-40125S 40x12x48x CD-Rewriter
- Modified Scorpio TA-10BD Full-Tower ATX Case
- D-TEK Customs White Water Waterblock AMD (Socket A)
- HWLabs Black Ice 2 Radiator
- Aqua Via 1300 Pump (370GPH)
- Swiftech Pump Relay Kit
The circulation of water inside the system will work as follows:
Pump --> Waterblock --> Reservoir --> Radiator --> Pump
Once assembled, the system was filled and tested for leaks for approximately 24-48 hours before the
final computer components were installed. To fill the system, I will be using 500cc of Morning Mist
Distilled Water with a cap full of Purple Ice. Purple Ice is a popular product that assists in
preventing corrosion and erosion of metals in the cooling system. I will be testing in two stages
using an Aqua Via 1300 AC Pump connected to a Swiftech Pump Relay Kit against the C-Systems CSP750
Brushless DC Pump. The Aqua Via 1300 is capable of pushing a maximum flow rate of 370GPH with a
delivery head of 6ft. The CSP750 is capable of pushing a maximum flow rate of 120GPH with a delivery
head of 6.5ft.

Testing:
The assembled test system was run through a series of benchmark applications to record system temperatures
and performance. The "Burn-In Wizard" from SiSoft Sandra Pro 2004 is used to put the CPU under concentrated
load for a pre-determined amount of time. The options selected in "Burn-In Wizard" run the CPU and CPU
Multimedia benchmarks for approximately 30 minutes. The system is left alone for approximate 15 minutes
before the burn-in test is performed. Maximum temperatures are measured in degree Celsius and recorded
for idle, full load, idle overclock and full load overclock confirmed by an independent thermal probe
locked underneath the Ziff socket and using Motherboard Monitor 5.3.6.0.
The system was run in normal mode at 1.8 GHz and overclocked mode (VCORE 1.65, FSB 145, Multiplier 15x)
in order to get the system running at 2.1 GHz. Ambient room temperature was measured at 28 degrees
Celsius. Overall, I was very impressed at how well a single CSP750 performed in this configuration.
Comparing idle, load, idle overclock and load overclocked modes produced a 2-3 degree margin between
recorded temperatures despite the lower GPH rating. After running a single CSP750 module against an Aqua
Via 1300 for a few hours there are two points that should be commented on. The CSP750 is near dead
silent during operation compared to the Aqua Via 1300 used during testing. To silence the Aqua Via 1300,
I had to use the famous crazy glue and impeller trick.
The second point to note is heat generated by the pump which can raise system and water temperatures.
The Aqua Via 1300 was extremely warm to the touch while CSP750 remained nice and cool during operation.

Conclusion:
C-Systems has developed an excellent PC based liquid cooling pump that is sure to grab the attention
of water cooling enthusiasts worldwide. The CSP750 is a very compact unit that will work extremely
well in cramped case interiors or SFF based systems. Consumers will appreciate nice anodized
finish as well as the 1/4" NPT ports which make this pump adaptive to 3/8" or 1/2" water cooled
configurations. One of the great benefits of this product is that fact that it is powered directly
using a 3-pin fan header on a motherboard. Consumers will not longer have to worry about using solid
state relays, power bars or PCI relay cards in order to turn on the pump when the system is powered.
During extended hours of operation the CSP750 generated very little heat and was near silent during
testing. While the tests performed in this review are not as conclusive due to time restrictions there
are other factors that should be considered. In the future, I will be conducting some more extensive
tests using a Hydro L30 II, Eheim 1048 and Eheim 1250 against the CSP750/CSP-X2 packages. Consumers
looking at running multiple water blocks for Chipset and GPU cooling should seriously consider using
the CSP-X2 package instead of the single CSP750 package. Overall, I was impressed with the C-Systems
CSP750 Brushless DC Pump and rate this product a final score of
8 out of 10. If you have any questions
regarding this review be sure to visit the C-Systems
website for more information or discuss them in our forums.
