Zalman Reserator 1 - Fanless Watercooling
i did a search here on the forums and it seems nobody mentioned the Reserator yet. i'm thinking about getting one.. it seems to perform rather well for a fanless setup.
http://www.zalman.co.kr/usa/product/...dx=63&code=021 a review by bit-tech http://www.bit-tech.net/review/315/2 i'm thinking what waterblock would make the setup perform better, thats of course without changing the pump. it comes with a qmax 300, 300l/h so thats about 80gph..fairly low (forgive my noobness, but i'm trying to make sense of what i read) http://www.overclockers.com/articles373/wbsum.asp a waterblock with lower c/w, lower pressure drop - psi/inches h20 will perform better than the zalman block in the same setup, is it correct to assume as such? for example the zalman waterblock is rated as 0.17 c/w 0.56 pressure drop - psi 15.5 pressure drop - inches h2o the swiftech mcw5002 is rated as 0.15 c/w 0.31 pressure drop - psi 8.6 pressure drop - inches h2o the dangerden tdx 0.14 c/w 0.51 pressure drop - psi 14.1 pressure drop - inches h2o the dd maze4 0.18 c/w 0.12 pressure drop - psi 3.3 pressure drop - inches h2o so in this case, given that nothings changed except for the waterblock, the performance would be swiftech > dd tdx > dd maze4 > zalman ? please advise. |

You could build a fanless setup much cheaper and have it perform better than that thing.
Pressure drop really has nothing to do with the cooling ability of a waterblock. The internal structures and the design have an outcome on the pressure drop of the block, but if a block has a lower pressure drop it will be able to flow more water.

(to toot my own horn, or in this case, the one of my colleague!). It's not flawless. |

To get it to perform up to acceptable standards, add a heatercore to the loop and then throw out the shitty little pump for a better one and all you got left is a fancy looking resevoir. But yeah, I would lay odds that the block isn't much either.
Have fun throwing your money away, seems to be a trend.....don't forget your golden water to put in there. |

I'd be curious to know if there are other options for silent cooling. Heatercores are designed to require airflow, and don't lose much heat without a fan on them ... so what else could be used? Besides ugly copper piping "loops" which have been done in the past ... are there other options for silent cooling?

I've played around as well ... and unless I was stacking a large number of heatercores (backpressure+++) I doubt I'd have much success cooling an actively running processor and gpu with any real degree of success. The zalman passive cooler/reservoir has a great concept ... but I'm sure it can be tweaked some.

Yeah Karma is right. What you can't get is performance and quiet in a case for a decent price. The Zalman reserator will get you a silent PC. It will be crap for performance, though. You know how I know it will be crap, without looking at a review or handling one myself? Because Zalman explicitly states "not for high performance cooling." If they don't state that, then the thing is probably crap. If they do state that, you've got a sure thing.

not to mention, there won't be any need to mod the casing to fit the heatercore/rad, drilling of holes to fit fans, barbs, tubes etc. and at the end of the day there won't be any noise. for its intended usage it seems to perform very well to me. last i checked this is a forum to discuss watercooling, low or high end. if these forums are only limited to high end watercooling discussions then i believe i have come to the wrong forums.

you guys are saying a car is slow because planes can go 10x faster. thats a stupid remark if you asked me. the car is not slow, just that it has a different intended usage -- and for what it is intended for it is fast enough. but of course thats just me. Quote:

I really don't understand why you're taking criticism on the unit as criticism on yourself. If it fits your needs, buy it. |

constructive criticism is of course welcomed. but i don't think saying it sucks without reasoning is constructive EDIT: so far the current reviews shows it being a pretty acceptable water cooler performance wise. im just wondering if a better waterblock would improve the performance. |

looking at that graph, at low flow rates, the Swiftech MCW6000 is the best performer. I dont know how much of an increase in performance you'd see over the Zalman block, but I expect you'd gain a few degrees C.

Paying $200+ to cut down on a few Db of noise is a fools use of money. No performance is gained over stock air cooling, and it certainly can't be compared to a normal watercooling loop. Simply relocating your box under your desk with stock cooling would have the same effect. |

and if you have nothing more constructive to contribute i beg you not to reply. i started this thread to discuss the reserator, and not bash it based on what you want to believe EDIT: BalefireX, thanks for pointing me to the graph, i read the review and that block might just be what i was looking for. |

THe bit tech review does show that the resorator beats the sp94, but only just and it even preform worst, in some instances. I simple h2o setup with a swify block, a radiator and a low rpm fan and a small ehiem pump, would likely be a far better (and cheaper) alternative.

The bittech review is poorly done and poorly measured. It is irrelevant. If the Reserator was on par with the SP94, Zalman would call it ultra-high performance, but it isn't.

i guess to improve the performance -easily- would be to use the mcw6000 waterblock in place of the zalman one?? Quote:
first of all we're comparing a kit to a heatsink. not a waterblock, a radiator etc. so i guess we can forget about the performance level of each individual component and compare it as a whole -- and thats what bit-tech did. IIRC the cpu thermal diode on an Intel processor is internal so i think the readings would be fairly consistent & i don't see how it can be poorly measured since its pretty straightforward *i do not own a p4 so i don't know for sure and by the way, if you don't already know, it doesn't matter what the manufacturer call them. thermaltake claims their products are the best, so you are gonna believe it? thats what these forums are for. |

Does it really matter if his processor is at 30C or 40C? Okay, he could probably do 10 degrees better using an actively cooled system of similar price, but what difference is that going to make? Sure, hypothetically his processor's life will be extended, but to what extent? It will last 20 years rather than 15? Who keeps a processor that long anyway? Or perhaps he could overlock more, 200mhz maybe... thats gonna give him an imperceptable speed improvement or an extra 12 3dMarks...
My point is that Watercooling as a hobby is about fun and fulfilling your personal goals. Sure, there are cases where you need it to cool exceptionally hot processors, but the majority of the time, its done for bragging rights, overclocking, or silence. If you visit www.silentpcreview.com you'll find there are people there as crazy about silence as the people with Dual Phase change setups are about cold - its just a different direction. I like this site because it takes cooling very seriously, but deep down we have to remember we do this because we enjoy it.

The review is crap, the system is overpriced. A do it yourselfer could get a cheap ass weak pump, a home made copper resevoir made with hacksaw cut fins (better than what they got), and the cheapest block on the market, all for easily half the price. Why hasn't anyone been doing it? Because it would still suck. |
