Refrigerator unit for liquid cooling systems!

[polar bear]

There is no way in hell a D5 will pull 1200l/h with blocks and incline. I think you missed me telling you this about 4 times already.

No, I just didnt understand why initially. I thought my D5 would give 1200 LPH under ANY circumstances, well of course now I understand it is under IDEAL circumstances only and it would mean at almost no resistance i.e. head. I have just started looking into Martin's and others flow/head calculations, kinda a lot of info to swallow in just a few days time but I'm getting there. And with a separate circuit for the chiller only you wouldnt have to subtract flow rate for blocks, rads etc. The resistance to flow would be only that of the chiller itself.

The reason why i say you need a reservoir is because that way you have a headroom.

According to thermo, it takes about 350W traveling at 1.5gpm for water temp to change 1C. Thats a lot of heat required. By having this chiller attached to a larger reservoir, you have large volumn acting as headroom. This will always allow your chiller to be used far less, it would pulse instead of be on all the time.

Yes now I am starting to get this too... thanks for explaining though. Just can't understand why this unit requires such a massive flow rate...

As i said i have one of those chillers, and i already considered the idea of using it, but there isnt a pump out there which doesnt dump a ton of heat back into the water that you could use to pull this off.

Then i discovered the most covetted pump of our hobby, the RD-30. 30feet head on a pump a little bigger then the D5. But its also priced 4x-4.5x if you include the required psu.

Ehh but the RD-30 has the same flow rate as the D5 listed, which I presume is under ideal conditions... 1200 LPH. It differs of course in the head pressure of 10m. It certainly is expensive though.

In his thread camouflage is using an Eheim 1250 (1200LPH, not sure about head).

So yeah, if your going to spend all that money, why not just phase? A builder could easily build you something much nicer and which will last longer, better tuned for computers,

The cost/peformance ratio on this unit is so not worth it. 250 dollar pump system. 600 dollar chiller, then you'd need blocks, and everything.

Last time i checked, almost any custom builder could whip something for you cheaper on a SS phase unit, and drop the gpu's on water. Still end up being cheaper.

as I said earlier I havent decided on anything just yet. But seeing camouflage's thread got me thinking as to whether it may work. Phase... dont even get me started. Perhaps after a few months of reading/researching yes. Well, I'm going to stick with my new rads (which I haven't even received yet ) then lets see what the next upgrade would be.
