MCW6000/ too Restrictive?

[Psyche911]

I can't remember, and the reviews and threads I've checked don't mention it. I'm wondering with the upcoming single-pass rads at DD, if I should go for a high flow route. MCW6002/Maze4 GPU/5/8" OD T-Line/MCP655/Single-pass rad.

I know the rest of the system would be good for a higher flow system, but not sure about the 6002. With a single-pass rad, I'm correct in assuming you better have decent flow to get maximum water through it, right?

Maxxxracer said somewhere in these forums that the 6002 is more restrictive than the TDX

K R sure he will be along soon to confirm/deny that =p

[racinjimy]

just a fallacy...

the pressure does not matter as long as the flow is there.

what is true is that u need a high pressure pump to get good flow rates with high restriction blocks. this is true of all high restriction blocks be it impingement or not.

btw the mcw6002 is actually more restrictive than a TDX. shocking aint it :p:

Okay, thanks.
But since the 6000/2 will give better performance than a TDX according to the Procooling graph ( http://www.procooling.com/html/pro_testing.php ), do you think the difference in restriction is worth using the TDX?

Basically, would it be a bad idea to use the 6000/2 in the loop described above?

hmm.. well its hard to say which would end up being better in the end as I'm not sure if u will be able to get over 2gpm..ack.. nvm.. looked at the graphs. no way in hell ur gonna get over 2gpm with that setup. stick with the MCW6002. if it makes u feel any better the TDX with #4 plate is about as restrictive as the MCW6002.

I dont find the 6002 very restrictive.. my 2-302 is more restrictive.

I gotta get around to measuring the flow rates eventually too I guess.. :rolleyes:

[MaxxxRacer]

well dereks testing showed the 6002 to be quite restrictive.. or we are all just considering hte TDX too restrictive compared to what it really is.. all mater of perception.

and i highly doubt the 302 is more restrictive than the 6002.

I did post the one pic of the MCW6002a I had shooting water out the outlet ~1.5-2feet into a bucket easily using my MCP650 with slight modifications.. pic is in the "MCP650 sucks" thread I believe.

Just a 2-302 hooked up wont do that quite as well, although its slightly larger ID on the fittings I believe so it could be slightly more water moving. I would say they are equal..

20 feet of pipe and both hooked up at the same time was rather.. dismal :P

I've got too much stuff going, cant get time for the flowrate results or to mod the MCW6002a to dual outlets.. :(

[MaxxxRacer]

dual outlets wnot help u on the mcw6002. it will hurt its performance.

what about the RBX?

[MaxxxRacer]

RBX is more restrictive than the 6002 and TDX (obviously).

[Psyche911]

Why do more outlets raise restriction?
It's supposed to be the other way around. Maybe you mean more restriction once they meet up at a Y?

[MaxxxRacer]

well the RBX IS more restrictive than the TDX.. thats been tested.

not sure exactly why, but it is.. i dont have a pHD in fluid mechanics so i really cant tell you. lol.

Okay, updating original question now that the Swiftech Storm block is out. All other hardware remaining the same...How much of a difference would it offer in actual temps? And at what cost (additional restriction)

I've seen the graphs on Swiftech's site, but I couldn't calculate for the life of me how much of an effect the difference in thermal resistance would make in the temps...

P.S. To clarify, with a single-pass radiator, water goes from one end to the other and then out? Or does the number of passes refer to the number of loops through the radiator (one end to the other and back = 1?)? Or are both of those explanations wrong? :)

[MaxxxRacer]

The temp diffence is entire dependent on cpu, radiator, pump, etc, etc. it is naer impossible to predict the temp difference in your setup. if someone was able to calculate the difference somethign would make in two peoples setups there were entirely different within .1C of the actaul change i would light my computer on fire and move to the omish country.

the only thing we can realisticly do is guestimate. but i will tell you know that your flowrate will go down a bit (nothing too drastic and it is less now as Stew updated the G4 design (thanks man!) and your temps will drop maybe 2c? any more than 2c is unlikely unless your running a maze1 with a eheim 1046.... and a mora 2 radiator (lol)

Single pass means the water goes in one side and comes out the other end. double pass is what all the BIX/P and HE series radiators are. The new X-flow radiators and the pa160 are single pass.
