Dual Rad sufficient for just an i7 920 ?

locoesse · 16 Dec 2009 at 22:52

Hey all.
Wanting to know if a dual rad would be sufficient for overclocking my i7 920 ?

As i can most likely fit a dual in quite easily into my case however a tripple i cant seem to figure out a way i could get it to fit.

The case im using is a xaser VI

EDIT oh also
Would there be anything "bad" about putting the radiator at the bottom of the case ?
It has a 3cm gap between the case and where the table is ?

Yeah. Had both a Swiftech and Black Ice 240mm rad cooling my 920 and they both did quite a good job.

Another noob question , what about 2 singles within the same loop ? is it that a silly idea ?

Or is that just what you said you have done lol >.>

Do you mean a double and two singles or two singles instead of a double rad?

Nah I had the Swiftech on there last year and the Black Ice this year.

2 Singles should theoretically work just as good as a double, and could possible be easier for you to fit in. Only real difference is the extra tubing used will increase the length of the loop and shorter = better really, but I dont think the extra difference here would be a problem. Just go for whatever is easier

I ment a double rad such as XSPC RX240 120mm Radiator - Black , Or 2 singles such as XSPC RX120.1 120mm Radiator - Black

Like would there be flow issues if i used 2 singles ?
Because i could fit that much easier in my current case

Oh thanks Ducky. thats what i was wanting to find out

locoesse · 17 Dec 2009 at 11:39

So the loop i was thinking was, Pump --> Rad 1 --> Rad 2 --> CPU --> Res --> Pump

The kit i would be looking at would be , What do you guys think ?

Pump - Laing DDC-3.2 (18W) No link as i can only find the ddc 1 on ocuk. I would use the XSPC Laing DDC Top.

Rad - XSPC RX120.1 120mm Radiator - Black X 2

CPU block - Swiftech Apogee GTZ SE CPU Water Block (Socket LGA 1366)

Reservoir - XSPC Single Bay Reservoir - Silver

Looks a good setup to me. Dont forget fans for the rads too, some good fans can make quite a difference. Akasa Apaches seem to get good comments but are ugly as hell haha. Something like the Scythe Gentle Typhoons or S-Flex fans are a good choice and a bit better looking too! I'd suggest getting a fan controller too, can turn them right down during normal useage so its nice and quiet and then have them running full blast for gaming and such

locoesse · 17 Dec 2009 at 14:57

For the CPU block.
will i need a backplate ?

Mobo is Asus rampage 2 extreme

Ducky Spud · 17 Dec 2009 at 15:16

Think it comes with one. I used to have a Swiftech GTZ (for socket 775, and it wasnt the SE version, so maybe different now) and that came with a backplate included. However if somebody has bought the one youve linked too then they'll be able to say if they're still including it with the new block

The surface area is very nearly the same in the two examples, but the singles feature twice as many 90 degree bends. Doubt the decrease from two singles is measurable, I did some basic testing on two 120 radiators vs a 240 a while back and the results were inconclusive.

A single thick 120 is more than capable of dealing with an i7. However you look at it it'll cool better than a H50, and those are wildly popular. Unsurprisingly the more surface area you use the better regarding temperatures. Noise is trickier, as more fans at lower speed make different sounds to fewer at high speed, and it's hard to judge which is better. There's probably a sweet spot around two fans on a double for an i7.

p.s. backplates are a good idea as bending the motherboard is never brilliant. 18W ddc is overspecified for a single block loop but will work just fine, consider a 10W instead.

Single 120mm rad would be fine

What's more important is the temperature of the air flowing through the rad. If it's proper ambient, and not recycling it's own air, you could easily put a gpu block in between those two RX120.1 rads, especially with that pump and XSPC top.
