MCR 220 or PA 120.2

[D_o_S]

Hi,

the question is simple:

2x MCR 220 or 1x PA 120.2?


Aiming for a quiet setup... want it to be able to cool QX6700/8800U

[Dragoon42]

if you got the room, i'd probably get the 2x mcr220

[lasse.j5]

PA 120.2 peforms better than the MCR but its also wider.

But a better peforming rads means less need for a high dB fan so i know which one i would pick if i were you

EDIT:

I didn't see that you wrote 2 x MCR

2 x MCR peforms better than 1 x PA 120.2, no doubt about that

[nibble]

If you can fit them in, 2 MCR220's would beat a PA120.3 most likely so I'd go with that if you can find the space. Actually now that I think about it a PA120.2 wouldn't be able to handle that system so you'd need to go dual MCR220's.

What you need to do it take a moment to stare at your case and plan things out. Will you be happy with 2 fat thingies sitting in your case along with a lot of tubing? Can you make it look nice? Most importantly of all, do you think what you planned is good enough for YOU? 2 MCR220 is better. If you decide to go dual, PM me.

PA 120.2 costs TWICE as much as the MCR.


But seeing as you spent (wasted) money on an 8800U, go with the PA, tho Im not sure if a 120.2 will be enough for a Quadcore and 8800U. 120.3 FTW.

i still think 2x mcr220 > pa120.2 or 120.3

Yep that's right...but the restriction will be pretty bad if you do series.

The only time parallel is a good thing is with rads :)

Hey I'm the one who thought of it! :P:D If anyone's interested I'll write up something...I'm the only crazy person here who has enough time to make tons of posts, do my hw, AND write random stuff up for people on the internet I don't know :D Its too bad Maxxx is too busy these days :( the more the merrier, and we have a shortage of people...

No I know why it works, same with electrical circuits. Two identical resistors in series = 2x the resistance. Two identical resistors in parallel = 1/2 the resistance. Makes perfect sense :) But then of course you have to mess with those Y fittings and extra clamps and such.

I say write it up. I would read it. Might even learn something from it.

Thanks, but the only problem is I'm always reluctant to do this kind of stuff because it seems that the majority of what I say, people don't believe...and partially because it was posted by...[evil music duh dun dun]that little kid serialk11r[dun dun okay enough crap].

i believe you in =D post something, I'm willing to learn something new

I'm not even sure 2 MCR220 would be enough to cool an 8800u/Q6700: especially if that furnace known as the quadcore gets overclocked.

You'll need a DDC pump if you're going with 2 of those rads in series.

LOL ranker you're turning more xtreme than IanY!
Correction to the last sentence: you SHOULD buy a DDC pump or something else with a ton of max pressure, and FORGET about series for the rads. Series for rads kills flow like the crazy guy at virginia tech killed all those people :stick: nah its not that serious but there really isn't a point to doing series besides simplicity.

No offense, but I laughed at him when I first joined these boards. Hell I laughed at everyone for being so obsessive. Ironically, I found myself being slowly sucked in and now see almost eye to eye with Iany on a lot of things. It's a hobby...an addictive one.. expensive as well. Thank god I'm not like this with cars.

[zdog]

parallel for the win. just like my twin intercoolers on my car. series is less efficient and huge boost drop but in parallel i only lose 1 psi and intake temp drops dramaticly. just try to keep your tubing length and bends simular for both rads the the pressure and flow will be as equal as possible through both.

lol IC what you mean. First time I came, I was like "what? this crazy guy made ONE THOUSAND posts...he's wierd" and look at me now :) I also was like "huh??? why the hell did this guy pour all that money on 8800gtx sli? that's stupid." IanY was nice to me so I didn't laugh at him but I did think he was crazy...

Well, I was planning on running an Iwaki MD30...

I have a budget of like ~$80 I want to spend on the rad, so thats why I said 2x MCR or 1x PA

With an Iwaki, I really don't think we'll need to worry about restriction... get the two MCR's then.

[D_o_S]

Hm, just looking at the Iwaki... can someone tell me which model I need exactly? Iwaki MD30... (RLT, RZT, or...?)

EDIT: nvm, found its RD30, not MD...

[nibble]

A DDC2+top should be able to handle 2 MCR220's in series with 2 blocks, I always thought rads had relatively little restriction? From my experience water shoots into my mcres and creates a lot of turbulence after going through 2 rads, a D-Tek Fuzion and an MCW60, very unscientific I know.

[septim]

crazy addictive hobby we've all got here...

with iwaki rd30, get 2 mcr220 and series them...
also with iwaki rd30, don't forget the power supply for it and where you'd fit it with your 2 rads and pump too...

[burton]

i would go with two mcr220's
