CSP-750 Pump Question

Im looking for a quite pump that will not vibrate and annoy the hell out of me like my current pump the via 1300 (suggestions very much welcomed).

Now I hear the CSP-750 is great pump thats very quite and keeps vibration to a minimum (true?) but would it be able to handle pumping through a multiblock system (cpu and gfx).

Thanks for any help :)
 
for very quiet pumps i would say go eheim a 1048 is nearly dead silent also i like to use submerged pumps like the eheim s600 or s1000 they are just as silent but also in a resavoir the water dampens the noise even more.

i was looking into getting a c-750 pump to replace a thermaltake pump. the specs look good for my rig but i have heard some people say there are somewhat crappy.
 
Stay away from that 750 pump. It has by far the worst complaints of any pump I have looked at.
I have an AquaXtreme 50Z-DC12 and I find it fairly quiet (very low rumble). I also have an Iwaki and it is very silent.
The Eheim have good reps for being quiet, as do the iwaki MD series and the Bluelines (panworld).
So if you want AC power I say an Eheim or an Iwaki. DC get the AquaXtreme.
 
how about MCP350 - that's the best pump right now and with very low noise AFAIK.
 
the best low noise 12V pumps are the AQX-50Z, formerly Swiftech MCP600. That pump is not only quite quiet, but it is also one of if not THE best performing 12V pump on the market.

A newcomer is the LaingDDC. It is a very quiet pump with great head, decent enough flow and is absolutely tiny! The only downside of the pump is that it has only 3/8" fittings so it is not good if you are looking for a 1/2" system.
 
i have had 2 csp750 pumps in my system for over a month, and they are great. they get badmouthed a lot, but remember: this is the internet, EVERYTHING gets badmouthed a lot.
 
There's a difference b/n badmouthing and multiple, confirmed reports of these pumps failing due to internal leaks and rusting. Just visit procooling forums, u'll see what I mean.
 
Agreed, all pumps will have failures. Its just that for the 750 its the norm rather than the exception
 
you could find confirmed reports of any pump failing due to leaks, but people are eager to pick on the csp750 because the "smart" guys at procooling do.
 
OOohhh, being ironing and snotty aren't we? :eek: :D Are u trying to imply that the ppl over at procooling are stupid? Does that include Cathar too? lol man, if you want to be blind to facts, so be it. Anyone with brains reading those multiple reports with technical explanations and pictures will understand that the current generation of CSP750s should be avoided like fire.

BTW, be a good boy and find some reports of D4 failing due to internal leaks, OK?
 
haha, of course they arent stupid (but they DO love that everyone treats them like geniuses).

every picture of a failed, corroded pump has been the shitty, green-colored mark 1 version. im sure people claim to own a failed mark II, but how can you just believe what someone says on the internet? show me proof of a failed mark II and i might change my stance.
 
Whatever. Why take the chance, there are better pumps out there that don't have a bad rep like the c-systems. Personaly my equipment is too valuable for me to take that chance.
 
Looks like they have come out with a revised version yet again. Now I ask you is that the mark of a quality pump? Don't things get revised because the are borked? 3 revisions in less than a year = stay the fuck away from this pump

Mine is 118 and I thought I was stupid, lol, :)

As I've said I know people that have the pump with zero problems, I've also seen threads where people have nothing but problems with them. Take your pick but if you don't want to have any suprises or anything you'll want to get something like the new LaningDDC or D4 pumps.

ROFL! :D That's a good retort :) Admit it though, u love to be treated like a genius, which, btw, u r :cool:
 
I have a CSP750Rev2 pump.

They do get bad mouthed quite a lot, but I love mine. I only have one pump pumping my entire setup (CPU/GPU/Rad), and it is remarkably quiet. Upon first start, I thought the pump was broken, I couldnt hear it, but only after touching it did I feel that it is working (read below).

I have put mine onto a sock lol, to cancel any vibrations. Works like a charm. The pump does run a bit hot compared to others, but only about 2C to 3C hotter.

Work of caution though, when you get it, I suggest you turn it on for a second without the the water setup attached, just to see if the propeller spins. You can see the propeller through the barb hole. Also, most barbs, the part where the threading is, is too long. If you screw it in completelly, you will jam up the propeller, meaning it will not be able to turn, and will burn out.

And a wierd thing, first time I started my system, the pump was on, as it felt as if it was on upon physical touch, but water in ym system was not pumping. I was really pissed off for a second, as I thought maybe the tards at the factory put tape over the propeller, to hold it in place for transport. But upon restart, it spun up, and worked great ever since.

Overall, I love this pump, and would say highly reccomended, if you want a quiet set up.

It is never a good idea to start a mag pump without water in it. Its a one way ticket to failure.

I dont think it will die in 0.5 seconds.
 
yeah I guess c-systems put this in their manual just to take up space. :rolleyes:



The CSP750 inlet must be below the water
line at all times. NEVER run the unit dry
even for a short time, as this will cause
damage and void the warranty. For this
reason we suggest mounting at the bottom
of your case. Recommend position in your
flow path is between the reserve and
CPU block.

so now you have propably damaged an already failure prone pump. Good Job!

OMG YOU ARE SO RIGHT! And the manual for my CPU said dont OVERCLOCK IT!! OMG OMG OMG I DAMAGED IT TOO!!!!!!! NOOOOOOOOOOOOOOOOOOOOOOOOO




C-Systems put that in their manual, to take any liability off of them, if some tard lets the pump run for a while, which will overheat since it uses water to cool itself, and seize.

LMAO, classic. :D
Some people try to justify their options no matter what, I guess my CPU is totally broken now since it's OCed. :)
 
Listen there is a big difference between o/c your cpu and running a mag style pump with no water. It has nothing to do with my opinion, it applies to all mag style pumps. It is akin to "testing your car engine without oil".

You can act like a moron when you are told its wrong if you like. It does not however change the fact that you probably shortened the life of your already shitty pump.

BTW why would c-systems suddenly shorten their warrenty on these pumps from 1 year to 6 months?

For what it's worth, the C-systems pumps are direct shaft drive, not mag drive. And that's their weak point - the shaft seal between the pump chamber and motor compartment.

My bad your right. I was reading up on their new mag pump and had that locked in my brain. They are moving away from the dircect shaft because of the seal leaking that was causing all their probs.

The original point remains however.

CrimandEvil I am glad that you at least recognize they have that weakness. With the post you were making I just had you pegged as a fan boy who owns one of these and cannot admit it is junk. (because it has not failed -- yet)

When I was first looking into the csp-750 there was a guy who worked for c-systems who used to post at procooling forums. You might want to try and contact him, he went by the name hotseat I think. I don't know if he is still around though, he got ripped pretty hard by some of the guys there when the original pumps started failing. Its worth a shot though
he seemed real knowlegable and willing to help.
