How much cooling capacity needed?

[alexej1]

Hey guys, How much cooling capacity do I need for my i7 3820 and my 2 gtx 780s. I need some head room for overclocking. Without modding I can put one 280mm rad, one 120 mm rad. Is it enough ? This could be just right?

 

Tell me what you think about it.

 

Thanks

@alexej1 That sounds like just more than enough. The i7 3820 doesn't overclock that much does it? it isn't part of the K edition of Sandy Bridge-E processors like the 3930K or 3960X.

I would get a hold of 2 good static pressure fans i.e. Noctua NF-F14. I would doubt you need to use a fan to dissipate the 120mm radiator since the passive airflow in your case will be enough.

you will need at least a equivalent to a 120mm rad per component , so 1 280mm and 1 120mm is enough, and you still can overclock your gpus

Kind of pushing it, I would go for two 240mm's.

I agree, you're kind of pushing it. I'd do 2x 240's or a 360 and a 240.

But if you actually read the post (you never do that), you would notice that he can only fit the 280mm + 120mm radiators.

 

 

Ontopic: 280mm + 120mm will be just fine, but I would try to get +15fpi radiator for that.

Doesn't matter.

 

He could be using a shoe box for all I care, my answer would be the same. The components are what is relevant. 

 

Take your sass elsewhere.

Why even bother posting then?

Because

so I posted what he should use based on his components.

 

Note that an equivalent surface area can be substituted for standard 30mm rads. 

 

If you failed to understand completely what I meant by my original response, you could interpret it as:

"what I think about your choices is that it is just enough to work, you should obtain more radiator space somehow"
