WB à impact de jet

Ouais je sai j'ai vu, mais c'est chaud a souder des petits truc comme ca non ?

non, fait etre minutieux et ca va tout seul
les bases m'en reste encore.

Et si t'es fort et que tu t'en fous de payer EDF , tu prends une IWAKI qui suce 80W (et qui doit pas être silencieuse) et t'obtiens ce genre de jets de 5-6m avec un cascade :





Vraiment fous ces ricains et australiens pour gagner 0.5°C sur 100W (sans compter que ce genre de pompe dissipe un max ds la flotte en + ). Vaudrait mieux optimiser ds l'autre sens avec le moins de puissance possible c'est mieux..

mort de rire
ta pas interet a les coller les tubes

trop fort quand rosco se fait chier le dimanche il nous sort des truc de ouf!

C'est la maison de Cathar et c'est le nouveau cascade alias STORM (genre ca pète tout )
Une IWAKI au cul d'un protoz et laminé le STORM

vaut mieux pas prendre ca pour un direct die sous peine avec un proc avec un trou dedans

Bah ca doit faire de bons massage vu leurs vitesses c'est sûr
D'après son débit relevé ds un circuit fermé les jets font du 10m/s environ.

Avant c'était les russes qui gonflait les perfs en mettant des moteurs de fou !

Niveau énergie, les ricans font pareil, le jour ou ces pays se mettront à l'optimisation, on avancera ptet un peu !

Mais bon, les iwaki aux USA c'est pas un pb, si t'es patriote faut consommer, c'est mal vue d'éteindre la lumière... la journée ! Alors bientot 2 iwaki en // pour watercooler un shuttle ?

la base de 0.8 va pas faire long feux

je comprend pas bien c est vraiment necessaire ?
ou c etait juste pour le fun

car je ne voit plus l interet de gagner 2 degré le proc une fois a 35°ca serta quoi de^perde 5 degré il ne montra pas + en oc si ?

a comprend pas

le fun

Bah la perf avec un jet ne peut qu'être meilleure qu'en allant plus vite (en suposant qu'il soit a bonne distance) donc faut pousser mais l'intérêt est discutable niveau T°, je vois pas que ca comme aspect qd je fais un bloc, chacun son truc , en tout cas je mettrais jamais 80W de pompes ca c'est certain ^^

Va voir chez les ricains tu verras c'est des ouf, les ventilos Delta à 50dB et les doubles D4 en série c'est presque monnaie courante là bas (j'exagère à peine )

c est quoi un double d4?

2 pompe Dangerden D4 = 2* Swiftech MCP650 en série

Oh cathar is in the place

Hi, thought I'd explain what was going on with those pictures. First - I do not speak the French language and I attempted to understand what was being written above through use of an automatic translator, so please forgive me if I misunderstood what was being written.

The Iwaki MD-30RZ was only used because it was the only spare pump I had lying around. I do not use the MD-30RZ in my water-cooling systems, because as Rosco says, it dumps WAY too much heat into the cooling loop.

Most typically the Storm block is intended to be used with a pump like a Swiftech MCP600, or MCP650, although it can be used with a pump as weak as an Eheim 1046 very effectively.

While with the Iwaki the jets achieved 10-10.5m/s velocity, with the more sensible MCP600 the jet velocity would be more like 5.5m/s. Compared to the Cascade block, the Iwaki MD-30RZ was previously required to get those sorts of jet velocities. Another comparison can be made between the Eheim 1046 and the Eheim 1250. With an Eheim 1046 the jet velocity on the Storm is roughly equivalent to a Cascade block when used with an Eheim 1250. I considered the jet acceleration effect within the Storm to be a major step forwards for bringing high pumping power effects back down to being achievable with pumps that are more sensible to be using in a water-cooling setup.

So no, I do not advocate using super-strong high-heat pumps within a water-cooling setup. Those pictures were taken mostly for fun.

My pursuit has always been in improving overclocking capabilies of waterblocks. One of my private goals was to achieve 3GHz on an AMD Barton core CPU with room temperature water-cooling. Just a few days ago I was finally able to achieve that goal.

nice job

Yep I know and I understand but overclocking capabilities are very dependant of your cpu, mobo, etc... And with Barton Mobile it's easier than others CPU (generally)

In our database TITOUILLE do a nice 2500+ Mobile @ 2947 MHz @ 2.1 V with a simple homemade watercooling (no monster pump, etc..) when others people are only doing 2700 MHz max for example with another 2500+ Mobile. If you have a good Barton-M series you'll overclock well without a lot of difficulties (and up to 3.3-3.5Ghz with a compressor unit) but if you have a poor one, and even with a compressor unit, you won't be happy with a bad o/c .

People with aircooling (SLK900) have 1800+ @ 2774 MHz @2 V here, it's not a miracle but a very good series only . You are lucky or not with series

So in my mind, show only an o/c don't mean nothing and that's why I think you did a comparison between Storm and a regular Cascade or Cascade SS to see if a real improvement was here or not with the tweaked design (using multiple mountings naturally). Is it a 2500+ yours ?

les XP-M c'est des cpu de gayzor

Rosco, I seem to be sensing a certain amount of hostility in your responses.

The 3GHz overclock was not achieved using powerful pumping. Actually it was done using an MCP600 type of pumping power.

I am puzzled why you seem insistent to attribute my work as requiring very strong pumps. Of course I do have and use strong pumps in my testing, but I am not so stupid as to assume that everyone has pumps like I do. For this I also designed with the Eheim 1046 pump in mind as a minimum pump, as opposed to the past (Cascade/White Water) where I designed with the Eheim 1048 as a minimum pump in mind.

This CPU is mine. In fact I have two of them capable of achieving this level of overclock. Both are XP-M 2600+ CPUs. I have yet a third CPU capable of 2950MHz. I guess I'm just really lucky all the time? I do agree that it is important to have good CPU's if one wants to achieve high overclocks and that there are plenty of bad CPU's about, but even then 3GHz clocks are hardly "common", especially with just water cooling.

The CPU in the screenshot was only capable of 2650MHz on good air-cooling though. Hardly an indication of a fantastic overclocking chip. I am puzzled though, since this is perhaps the first time that a 3GHz speed with a 21C ambient temp on water-cooling (~24C water temps) using an MCP600 type of pumping power has been met with skepticism and an attitude bordering on hostility. Why is that?

I just wanted to explain my position since you seemed intent to label what I was doing as requiring ridiculous amount of pumping power, when really that is not the case. Again I stress, the MD-30RZ was used in those pictures purely because it wasn't being used in any of my water-cooling systems because I do agree with you that it is too strong and puts too much heat into the water. I would never recommend that people buy a pump like the MD-30RZ. In fact, I think you'll find that I often argue a strong case for pumps not much stronger than an MCP600, or Laing D4, or Danner Mag3 at the most.

I totally agree that most USA setups are somewhat stupidly over-powered and poorly designed. I believe that with a small quiet pump, 3/8" (9.5mm) ID tubing and a single well designed radiator with a single Papst 4412FGL could indeed match the performance of some of the best systems coming out of the USA.

i.e. I'm on your side here.

It's just said that your watercool system on an other CPU's (probably) don't allow you to reach this frequency. Today, Overclocking dépends more on CPU (MB too) than cooling systems. A good comparaison will be a test between some watercool systems on the same CPU.


But, your overclock is really excellent...

No hostility at all, you misunderstood or I have difficulties to show mu point of view . Why hostility from me? Absolutly not necessary. You do very good job and I don't have any reproachs to say you

I don't say that you are using a strong pump in your test like the Iwaki on the pics too, I know your system on OCAU... Overclock is far to be an exact science so you could have good processors like bad processors, databases are here to see this fact and world record are done with sorted processors to have the best one possible. I just say that hitting near 3GHz with a XP-M isn't a miracle (like TITOUILLE with a smaller CPU than yours) but not a common situation too

It's not against you when I talked about the pumping power and so on, but you know that there's a gap between USA and Europe about pump, high and low flow system, etc... (hot thread on Procooling about that). Both have their advantages and drawbacks. When I see, for example, american people how use IWAKI (40W) in their case or D4 in series for a single CPU, for the most people here it's a pure waste of energy, money, room and more noise. I think you dislike overpowered systems too. The potential gain provided by an "overkill" system (perhap's a bit strong the word) is so small that it don't change anything for a common use with a processor you use at 5% of its possibilities... It only increase your electricity bills

With a MCP600 for example and a good optimized system without 15km tubing, without elbows, etc you could have a very good watercooling system without spend a lot of money to have a monster system to do 0.5°C better
