C-Systems 12 VDC Pump review...

[Hotseat]

Hey I found a "hot spot", cool

Yes, I was lead designer for WB 2.7xxx, won PC mag online game of the year with that one. Was technical lead on WBIII, and yes do agree about it. Working on that project was one of the reason I move my company to RTP years ago.

Imagic went for full realism, more a sim then a game, took the fun out IMHO, but it was what people where asking for.

As for warranty, it applies to the Mark II, not Mark I.
The MarkII has a different motor, and frequency generation, which means people will start using fan controllers on it. Will likely go back up to a year, as soon as second trials finished with fan controllers.

We have yet another pump in trails as well, it will have 2-3 year warranty and be fan controller safe as we designed for them from the begining.

Thanks for thinking about me guys, not near any danger, going to south Iraq to solve a electronic temp control issue. Normally I have another engineer that handles this in the USA office, but he has just had a new baby and his wife is a little freaked out about him going to that area. Been in middle east many times, never had any problem.

Hey, that sounds promising, Dan! Your design is obviously set, but I'd really like to see a small, QUIET pump that offers:
- 50k-hour, 12VDC motor
- plastic wet side
- mag-drive
- more flow than CSP-750
- RPM reporting
- price near a Laing's

Should I hold my breath?

I'd have to second that. Except i wouldn't mind if the price was less.

However it would be interesting to see what you can make for that price.

[Razor6]

Not sure why someone would request a price near Laing because at that point you might as well get the Laing. Equivalence with less price is what I desire.

[Tos]

I just wanna add my stone to the small " I'm happy with my CSP750 that works fine and I don't see why people bash Dan " stack

At least 1 of my CSP750 works, the one I have rethreaded to 3/8, had it run on an open loop overnight, no leaks, no issues, noise reduced ( I guess the ball bearings had to run a bit until the pump is really quiet ).

I'll test the 2d one later

Otherwise, I'd like to thank Dan for his patience and support, and hope he'll get back soon from Iraq

[Hotseat]

Hammer, this is what people have been asking, and this is what we designed for

The only difference is people also asked for fan control, and honestly that was a bitch to test for.

Price should be very good.

Please remember the CSP-750 was designed per a customers requirements, at the time we didn't know much about what you guys really wanted.

Well off to bed, no I-net for awhile again I suspect, so I better download all the porn I can....J/K

Latest feedback from my CSP750 experiments ... running a couple of our black mk1.5 models ( older motor, mk2 casing, inline test setup with aquatube ... runs quite nicely, ultra silent, now testing for leaks

[ferdb]

I received a pair of CSP750 MKII's from Bigfoot. One had a flaky 3 pin connector which I had to replace. You may want to keep on eye on whoever you have crimping those connectors. The other pump would occasionally not start on application of 12V, although it would hum and if jarred would then start pumping. One pump started out generating enough flow in my system (MCW6000 block, BI Pro II radiator, one CSP750, 3/8" hose) to create 24" of head, the other managed about 28-29" of head. One was also considerably noisier than the other. After both pumps had logged about 24 hours each they both generated a pretty much identical 31" of head pressure and they had quieted down noticeably. I have not had any leak problems with them. I have not seen the startup problem again either since they've been broken in. After my early concerns I'm actually quite happy with these pumps. I wanted a quiet pump, small, reasonably priced, 3/8" plumbing, with decent performance for moderately overclocked extremely quiet AMD64 machines. The CPS750 fits the bill nicely.
Hope this feedback is usefull.

[deckard]

Just setup my brand spanking new CSP 750 Mark II from Bigfoot as well. After priming the pump I let her rip. It's operation was smooth, quiet and hassle free. I didn't see the issues that ferdb saw, guess it's just luck of the draw. Roughly same setup as ferdb as well, Swiftech MCW6000 waterblock, Thermaltake Aquarius II radiator, custom Nalgene reservoir, 3/8" tubing, CSP750, all on distilled water. On an AMD XP2000+ running stock I get a constant 28-29C (83-84F). A couple degrees cooler than my last pump (a noisy Thermaltake Aquarius II).

My question is: Is there any distilled water additive besides FluidXP that we can use to help prevent corrosion and algae? I've been hearing plenty of talk about Valvoline Zerex Racing Coolant over at OverClock UK forums (http://www.over-clock.com) about this additive. I dug up a data sheet on Zerex Racing Coolant, and it can be found at: http://www.valvoline-technology.com/data/valv/prodinfo.nsf/0/85256AE300727D2B85256CB60056BC36/$file/VR+Super+Coolant.pdf

I seen in previous posts and in the CSP manual that Water Wetter, Purple Ice and clones are big no-no's. Any ideas if this one is kosher?

Picture is of my setup during testing for leaks and proper pumping. For connectors I'm using 3/8" x 1/4" PolyPro NPFT Male Connectors with a little teflon tape on the screws. Great design on these little guys, easy to connect and easy to detach.

So far this pump is great Dan, thanks. Also thanks to all for participating in this thread, lots of good info.

I, too, found the operation of my pair of CSP-750 Mark Is to be vanishingly smooth and quiet (once softmounted/suspended on foam, not bare metal to metal contact, which makes an awful racket). I liked them so much, in fact, that I sold them--and ordered a pair of Mark IIs.

I tried using FluidXP before using a distilled water coolant mix, and was not satisfied with the results. Don't know about Purple Ice and Water Wetter leaves a nasty film after a while (normally more so in warmer running systems). I'm not sure on the Zerex Racing Coolant, but I found the Hy-Per-Lube brand Super Coolant (clear bottle with red cap, the stuff is transparent, light green) to be an excellent additive for cutting down on surface tension-related performance limitations and tube friction-related flow effects. airspirit of these very forums recommended the stuff, and upon trying it out, I was quite pleased with the results!

Do a search for airspirit's red glycol mix, which is for ~15% red glycol (Dex-cool from auto stores), ~5% Hy-Per-Lube Super Coolant, ~5% non-chlorine, non-bromide biocide (for pools) and ~75% distilled water. I have run this mixture in my own rig for a while, with two CSP-750 Mark Is, and found it to work perfectly fine. That was with a Tundra BayRes, D-Tek Pro-120 radiator, MCW6000A CPU block, NV-68 GPU block and Maze4 Chipset block.

I will be running a slightly modified version of his mix in my upcoming build. I plan to run ~10% Dex-Cool, ~10% Hy-Per-Lube Super Coolant, ~1% Activated Chlorine-Dioxide and ~80% distilled water. The new components are two CSP-750 Mark IIs, two Black Ice Pros, a Storm G4 CPU block by Cathar, the same NV-68 GPU block and the same Chipset block, but there will be two parallel loops, sharing my new reservoir, a multifitted Typhoon BayRes.

Edward_Ng, may I ask why were you unhappy with Fluid XP+? Was it the temps or something else? I'm considering putting it in my soon to be built dual loop and am currently undecided whether I want to plop that extra money for it. I'm curious in partucular to operation with MkII's, since I have two of these coming.

I had an immediate biological problem in my system within the first 14 days of running my system with the FluidXP. Not only that, but performance with it was not as even as good as with airspirit's red glycol mix. Finally, it cost me $50 for two bottles of FluidXP, which amounted to only a half gallon of it. If I were to buy $50 worth of materials to make airspirit's red glycol, mix, I can make several gallons of the stuff, that cools better, has not allowed corrosion in my copper & anodized aluminum cooling system and has not suffered biogrowth.

Well that settles those "non- this & non- that fluid" claims.
That's the answer I was looking for, thank you. I'll always take first hand user experience over any marketing bs.
I was curious since people have brought up a few issues that may emerge with anodized Al and Dan mentioned using Fluid XP as a trouble free solution.
I think I'll give airspirit glycol mix a shot. Sounds very good and the componets I'll be using in my dual loops are pretty similar to yours with exception that I have DD RBX and 2 BI Extreme rads planned for it. Same NV68 block. Good tip, I appreciate it.

[BillA]

note that Swiftech does not have any 'isssues' with additives causing corrosion of our anodized wb housings

- this is a C-Systems 'thing'

[Tos]

that is irrelevant information, as any idiot could run his pump with tap water and screw everything up...

additionnally, I dare you say that "your" pumps are tap water friendly ...

So let's not make assumptions on what pumps are better than others, since we don't know all the facts that led to this or that result...

finally, I'd like to add I've been test running my 2 CSP750 mk 1.5 ( mk1 motor, mk2 housing ) with 2 kinds of automotive coolant fluid mixes ( "Elf" & "Ford - Special Yellow for Hi perf engines" ), both with good results ( 1st with 80% distilled water, 2d with 90% distilled water mix )

[BillA]

you should read before posting
the comment was about additives, not tap water

and your "dare" ?
sure, Swiftech pumps are 100% tap water friendly - no, make that 200%

they are glass filled pps, high alumina ceramic, and stainless with some o-rings

next time stick to the facts, and investigate a bit - might save you from appearing to have more fanboysm than . . . . .

[DryFire]

Is tap water friendly even relevant? How many of us will be running tap water in our systems?

MarkoBarko....

[threeputt]

LOL!!! he ran it for 3 years!!!

[BillA]

different thread, different pump, different problem
drop it perhaps ?

good work there Tos for confusing everyone

and your short term testing is to what point ?
who provides the warranty ?
let them decide, no ?

[m4dd]

any news on availability? are you guys receiving your preordered pumps from dtek yet?

[allnighter]

As I mentioned in another thread, as of this morning, Danny says C-Systems has them packed and ready, he'll update as soon as the shipping comfirmation is received and than it'll be a matter of days 'til they arrive and start shipping. Add customs ti it and we're looking in cca. 5 days. So looks like next week. Hopefully.

Only prob is that only enough to fill old orders? What about new orders?
