Which 4x120 rad?

[Edward88]

Hi , im looking for a 4x120 rad for sflex f @ 800 rpm push/pull


Which one do you recommend?


Also, if i use two of them, is better go parallel or serial? is there any differences?


Thanks

Price/performancy wise probably nothing can beat Swiftech MCR420. Half the price of best rads at 90% performance. And with getting two of them for same price you get 1.8x better cooling . If money no object, go for XSPC RX480 or Black Ice SR1 480. I also would advise using Scythe Gentle Typhoon-s on rads instead of sflexes. Also quiet rads but better pressure to blow through rads, and many say that quiet enough upto 1000-1100rpm. +ball bearing=better for horizontal rad/fan placement. Rad flow restriction is too small compared to restriction of modern waterblocks to care about parallelising their flow. Go for simpliest - serial. Imho with that much rads you can rather think of splitting loops.

[Nanometer]

What he said. But I would still put the radiators in parallel. It wouldn't make much of a difference, but there is a difference nonetheless. And I'm definitely for using every advantage I can get. If you have 2 of the same radiators, put them in parallel or if you want simple tubing put them in series.

I already have 10 sflex f :p thats why i will use them.


What is for you horizontal ? it can be different things depending on the point of view :p

[Church]

Nanometer: buy putting rads in parallel you might gain maybe 5% in flow .. but i wonder if rad efficiency won't suffer from that, as halved flow in each of them = less turbulence and because of that i'm guessing possible little less heat dissipation. Also more spending on fittings (eg. for quality Y fittings, that won't cut flow like some 90deg ones), more overcomplified tubing.. It's purely theoretical speculation though, with no real test numbers behind.

Eh? Since when horizontal and vertical can be confused? :/

Maybe he's asking whether the length/width/height is horizontal/vertical.

Series or parallel for the rads makes little diff in cooling. Figuring out the parallel routing, cost of parallel fittings etc matters. I'd only go parallel if you got so much on one loop your worried about flow rates, paralleling rads would help a bit.

As far as the rad size and brand, it really depens on the heatload. If you way overrad and silence is the key, then spend the extra cash on some SR-1 etc type rads with LOW FPI density, great with low speed fans. If you need a bit more heat removal and don't mind a bit higher RPM (1200) the Swiftech MCR series rocks. If you over rad DEPENDING ON YOUR HEATLOAD you can run pretty close to silent, a very low hum from the PC.

Please understand the diff in rads and plan for your heatload FIRST.

Not the best choice in fans for watercooling, low pressure through the rads. You WANT a LOW FPI rad that can cool with those rather weak fans. They will work, but your concept of big massive rads would do maybe okay.

what is parallel? sorry, im a water cooling noob

Splitting the water flow so part of it goes through one radiator, and part through the other, and then joining it all back together after the radiators.

[Nanometer]

For our pump applications, I would imagine that the turbulence of the water would not be as critical as gaining back that extra head pressure. Both of these would be small anyways. Measuring this would be near impossible, only paper calculations could be as accurate to show the answer.

If you make a decision on a 120.4, frozencpu has a good deal on the Freser TFC -- http://www.frozencpu.com/products/78...?tl=g30c95s667

Wow, for $15 over the MCR I would pick that up for sure.

Wish I hadn't just finished my "updated" build a few days ago and promised myself (and the woman) I wouldn't upgrade for awhile

[-TYPHOON-]

what about the EK XT480??

. . .and it's still overpriced considering the MCR works better in the RPM range he's looking to use his fans in.

Yeah I realize that, I was thinking for me not for the OP

I have a broken in half MCR-420 (2 x 220's ) and they love my S-Flex F's.

[Scrotie]

Swiftech if you're on a budget.

Thermochill or HWLabs SR-1 are both pretty nice, but cost more.

I own all Thermochill rads, and one Swiftech. The Swiftech isn't bad, but you can definately tell it's a cheaper rad than the Thermochill. A buddy of mine has one of the HWlabs SR-1's and they are very nice as well. After holding his rad and messing with it for a few minutes, I kind of wish I had gone with those instead as the finish on them is much nicer than Thermochill's.

I use swiftech mcr before, great rads for the price but im looking for xtreme silence now, so i need low fpi rads.

In the loop i will use:

Bitspower full cover block for asus r2e
Bitspower mosfets blocks for asus
Watercool HK 3.0
Ek 5870 block
Ek multioption v2
Ek dual d5 top single loop

Also 4 QD from Koolance


Which rads fits better here?

The silence of the rad is more dependent on the fans used than the FPI. Stick some 1150 or 1450 GT's on the MCR and see if you hear it then.

yes, this one is approved.

I will use Sflex F fans, i already have them . . .

Which rad fits best this fans @ 800 rpm.

The rads will be verticaly placed

I'd still go with the MCR.

Again, if price isn't an issue, then you can't go wrong with HWLabs SR-1 series.

Stay away from Thermaltake crap as well

All your answers if you sit down and make an effort to learn and work at it. Once the stuff is at your door your stuck. Figure it out, we have given you the links to learn and become informed. 800 RPM is pretty low, you better have a low FPI rad........

Ohh, here is the link again.....

Well, half of that statement is correct.

Again, even if price wasn't an issue, the MCR still performs as well as the SR1 in that fan RPM range. This is for the 360 version but they all scale up the same for the 420.



I simply don't understand the "it costs more so it must be better" mentality around here lately.
