All things being equal, when cooling the CPU only (in this case a Q6600) how much of a temperature difference would one see between a single 120mm rad versus a dual of the same make (in this case the MCR120 vs MCR220)?

I'm cooling just the Q6600 using the ff:

D-Tek FuZion V2 w/ quad midplate
MCR 120
MCP 350 with xspc res top
Tubing is 7/16 Masterkleer
Scythe SFF21F

I used to run the Noctua NH-U12P HSF in a different larger case but moved to the Silverstone SG03. Will my temps be comparable with the single 120mm rad? I will be OC'ing to 3.4Ghz on about 1.3v.
 
3.4GHz on 1.4V? decent. Takes me 1.6 to hit 3.7 on my E6300, and 1.6 takes me up to 70 and beyond :eek:

anyways, depends on the fans!
 
yep yep to above and will add that the bigger rad will allow you to achieve better cooling with quieter fans. With a single 120 (which can dump a ton more heat than your CPU will ever generate) you will need a higher speed, noisier, fan to get the same results as the dual. The single 120 will do the job just be sure to get a high speed fan and put it on a controller so you can dial in the cooling vs noise. I recommend the dual because a rad is a rad and 5 years from now you may put a GPU block in the loop.

The primary factors in rad cooling are.

The area of the fins
The difference in temp between the coolant in the rad and the ambient air.
The volume and speed of air flowing over the fins.

You will be doubling the fin area and 2 x 1800 rpm 60 cfm fans is hella better noise and cooling wise than one 2400+ rpm 90 cfm screamer. So its hard to say what the temp improvement with a dual over a single would be, its all about the fans as mentioned above. But there is no question the dual would be better and quieter and position you better for anything you do in the future - if the budget can afford it
 
There's no way a single 120 can handle a quad's heat load. You need at least 2x120 for a quad.

I kinda disagree with that. With the proper fan, a quad pushing 150w would easily be cooled by a single radiator. I mean, sure, the tdp for a heavily overclocked quad is in the low 200's the actual heat dissipation is quite a few watts less.
 
I run a triple rad with 3x 120mm yateloons. Even at 100% power they are very quiet and the cooling is pretty good.

I say go with a triple rad if you can, but if space limited then 2x120 minimum.
 
Too be honest those temps are not terrible.

My quad at 3.5 1.5v loads at 60C and I have a triple rad with Scythe S-Flex fans (some of the best). I'm using a Fuzion V1 with the quad nozzles.
