280mm rad for dual CPU loop?

[Smoblikat]

I have an EVGA SR-2 and a pair of Xeon L5639's that im looking to drown, I do plan on overclocking as much as I can. Do you think I could run both CPU's overclocked on a single 280mm rad, or do you think I would need to run a 420mm rad for this setup? I was looking at the black ice stealth GT radiators, I would either buy the 280mm or 420mm version of those rads, and pair it with a couple of these:

Also, whats the recommendation for a pump? I dont have any plans to WC my GPU's..................but im sure that will change once the system is up and running 😀

u don't oc xeons )=

I was thinking the same thing.
Overclocking just the video card?

If those are older xeons you have the BCLK overclock.

Also, a 280mm rad would work, but more is better. 😀

You can overclock those. Lot of people have gotten them over 3GHz. They are a bit power hungry, and probably want to cool the chipset too if you will be running a heavy load across both of them.

how tolerant is your noise level?
😀

You can watercool those xeons easily on a 120x1... with a uhh... 200+CFM delta screaming... 😀 no joke....

You up the size on rad to compensate for noise.
Also a 240mm rad isn't that much worse then a 280mm fan.
In some aspects id wager the 240mm rad will be better because they don't make Scythe GT's in 140mm... 🙂

Black Ice Stealth GT's are crap radiators also...
They are high FPI requiring loud and powerful fans to get any performance out of them, which brings about another problem as there is no 140mm fan with high static pressure required to really push those rads.

My Recommendation would be a thicker lower FPI radiator, like one fro coolgate, or if your on a budget, a MCR series from swiftech may also be a viable option.

But will a 280mm rad work?
Yes, it should work.

Oh come on, who notices 70 decibels anyway? It's just background noise.

For an airport.

Shouldn't a high FPI be better if you actually do have loud and powerful fans, though? That's how it has often worked with HSFs.

It is disappointing that the 140mm fan segment hasn't matured in the high static pressure department. Too few server-class 140mm fans I guess.

yes if you have the fans to support them.

however low fpi means quieter fans can achieve a better cooling ratio.

Less force is required to induct air though the fins....

Right. Some of us like computers that sound like vacuum cleaners! Just . . . not very many of us.
