C-Systems 12 VDC Pump review...

[allnighter]

By the way Danny has updated the front page.
Nothing is mentioned that would suggest an answer to your question psychofunk.
I'm thinking how it would make sense to get a shippment in that is in greater quantities than what's currently on pre-order but I guess we'll find out for sure rather soon, it seems.

unregistered : I was replying to this crap :



with all the ppl speaking about additives and stuff "not to be used on CSP750 pumps", I believed there should be another point of view ( also, it's getting annoying to get constant bashing ... ), thus the "tap water" theory.

my " short test's " relevance was to point that it's not all about additives, there are some quite good coolant fluids out there - at least in France.

And I've tested my pumps for deposits & greasy films someone has reported.

[BillA]

sorry Tos, I still think it was inappropriate to raise the issue of tap water in this thread
I know full well what tap water can do, and the above photo is not that

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.

This info is really interesting to me also as I was considering FluidXP for my first rig as a safety thing. The manufacturers claim ZERO corrosion. Just for clarification-you ran straight FluidXP correct? Also, how many degrees worse was it than your "secret sauce" coolant mixes. Thanks for the "real world feedback".

Back, well have INET again

Just for your info guys, effective Nov 1, I will not longer be in charge of the day to day operations of C-Systems.

We have sold the company to a Canadian group.

This should have little effect on you guys, as AVT Canada will still be providing manufacturing and development services to C-Systems.

Several of the C-Systems staff will be remaining, Dave and Julie being the most well known.

The decision to remove C-Systems from my group of companies was forced on me, based on AVT insurance carrier decision to stop providing liability to “any product for the home computer liquid cooling market”.

C-Systems is in very good shape $$ wise and always has been, maybe even better now, since the new group seems willing to commit more resources then we where at this time.

The new pump is still on schedule (don’t ask me date, will not be till next year sometime), and I will drop in when she comes out to get development feed back.

Still a cool little company guys, and I will still give her my commitment as best I can

Later,
Dan

Great to hear that, Dan; glad to see Dave is sticking around as well. I can't wait to see the new products that he told me about--in particular, can't wait to receive the sample for review that he mentioned!

Hansfragger, I'm sorry but I never got to do a direct comparison between the Fluid XP and the airspirit mix. The reason is because the situation with the bio problem was so bad I had to make the change ASAP, with no chance to do more formal testing for comparison. I will say temperatures were a good 10C better, believe it or not, but the system changed so much between the Fluid XP arrangement and the red glycol coolant arrangement that it's likely we're talking about compound improvements in flow, system restrictiveness etc. all adding up to create the massive 10C improvement.

With the new Storm G4 water block that I received, I plan to reassemble the system again, but this time I'll be adding less red glycol to the mix, in order to have a less viscous coolant mixture, which will work better in conjunction with the new block, as Cathar has mentioned that the Storm is particularly sensitive to coolant viscosity. The system itself has changed quite a bit as well, with two Blakc Ice Pros replacing the single D-Tek Pro-120, dual Globe 120mm fans replacing the single Antec 120, a reservoir with dual 1/2" outlets replacing the previous one with a single 3/8" outlet, and pretty much two completely parallel cooling branches, sharing only one common component, the reservoir.

Furthermore, I've sold my CSP-750 Mark I pumps and the new system utilizes CSP-750 Mark II pumps, one in each branch of the loop. There are more pics, of the pumps, the radiators and the reservoir, as well as a link to pics of the new block, near the bottom of this page.

Ed,
We have never seen a Bio problem with XP, in any of our industrial test set ups.

Now, I'm not an Bio or chemical expert, but will suggest this.

All our set-ups had methanol / water mix run first. Perhaps the methanol removed the bio problem, hopefully other more qualified can answer that?

You should also note, we NEVER use glycol in our industrial app's, just methanol for sound engineering reasons.

Good stuff to know!

I'm really not sure how the bio problem occurred, anyway, but the fact of the matter is that it did occur, and I've not had one since switching to airspirit's red glycol mix. Either way, I've not seen any corrosion whatsoever running his red glycol mix, and performance of the cooling system was already better than expected, so I'm not excessively concerned about using Fluid XP again. Another problem with the Fluid XP is the cost; for what I pay for two bottles of Fluid XP, I can make several gallons of the red glycol coolant mix.

Oh and yes, it was straight FluidXP; they don't recommend mixing it with anything else at all, and so I didn't.

Dan, my e-mail address for review-related materials is edwardng@silentpcreview.com. Any chance you or Dave can let me know when you guys have some samples ready for me to review of your upcoming pump products? Ask Dave about which pump he said he could send me (and a sample to Mike Chin as well, as he would do in-depth sound pressure measurements and actual recordings of the pumps for our readers to listen to!!! I don't want to mention any more about this in here, since this thread is really about the CSP-750 Mark I/II pumps.

Say, speaking of Mark II, is it just me, or are the Mark II pumps heavier than the Mark Is? I noticed, also, that the Mark II aren't quite as square as the Mark I pumps; they're wider and taller, but equal or lesser in depth (going by the shiny badged side as the front). Any chance you could hint us in on how flowrate of head was improved over the Mark I?

[Hotseat]

Will talk to Dave tuesday, know he is very busy, since most of the staff has the Flu

The first MarkII where a little heavier, should be same weight as Mark I now.
The Mark II is 0.100" bigger in all dimensions.

Zero head flow is up about 10 gph

Bio problem will occur with normal water, this is why we use methanol.
**We also use it to help with freezing point

I have read somewhere that methanol seeps through PVC tubing and is toxic; while I do not know if this is true, I didn't really want to take the risk.

[allnighter]

On another note, has anyone had their order through D-Tek filled by now? I'm still waiting and it has been some 4 days since Danny announced that he got his shippment in.

[Tempus]

I got an email from D-tek saying it had shipped and a tracking number for USPS. But USPS has no info yet - just the standard "waiting for the package."

[allnighter]

Hm. I guess you're among the lucky ones than. Still nothing over here. Although it has been "only" 25 days that I got my order in. I have full understanding for all the problems but my frustration in hardly any less. I guess I should have bit the bullet and got the pumps from Bigfoot a long time ago. Hell it would have been only a few $ more.

[Tos]

FYI, Methanol is highly volatile & toxic - thus, a no-no in watercooling.

I don't know about the porosity of PVC with methanol, but I wouldn't use it anyway..

[jaydee]

Anyone else have this issue? http://forums.procooling.com/vbb/sho...353#post128353

[Caliber]

So would it be possible for someone to give me a sum-up on how this pump performs, if its a good choice?

[DryFire]

Pros:
Small Size
Low noise
A DC pump
Approximatly equivilant to an eheim 1048
Cheap

Cons:
Al housing
Possible issues with used in series.
Unproven
Hard to find sometimes

I would love to get my hands on one personally but since I'm not in a rush i will wait instead of ordering one from canada.

Whats these troubles with the pumps being used in series? What would the performance of two in series compare to?

linked in the post above yours.

I have not heard of any problems, and most likly if you don't put them together without an obsticle in the way (like the rad) you should have no problems.

Would you say an eheim 1250 is a better, more safer choice if you've got the necessary space? Im also wondering wich of the c-systems these ones are, the mk1 or mk2? Whats the difference between the two of em? And just to clear things up: Yes, i am new to watercooling...

[Edward Ng]

The ones pictured are MkI.

MkII pumps have a revised motor assembly that runs cooler and provides some more flow/head than MkI. Physically, the MkII has ridges on the sides, is somewhat taller and somewhat wider, but not as deep (only 2-3mm here or there compared to MkI, which was exactly 2" in each dimension). Finally MkI has a C-Systems logo outline engraved into the face and just slightly filled with silver paint, while the MkII's entire face is mirror chromed with the logo engraved in black.
