Which rad: 120.4 or 140.3 ?

[dpajur]

I got a cheap used TJ07 that's undergoing painting at the moment and I plan on making this my next project

I'm going for a single 5870 and i7 930 hopefully overclocked to 4GHz. I'm hoping to do this with a single loop and a quiet setup, so 600rpm fans or as close to that as possible.

Is it realistic to expect one loop to cool both? (I hope so!)

Would I be better off with a 140.3 or 120.4 rad? I'm under the impression that their performance is almost identical, and 3 fans would be quieter than 4. Would love to hear your opinions before I buy!

Look at the data and then draw your own conclusions to make a decision

I'd say put whatever biggest rad you can fit. Of course definition of 'fit' differs for different cases as in requiring or not moding/cutting and willing or not to do such mods by owners. Bigger/more rads=less fan speed to reach wanted cooled temps=quieter.

You can fit a Feser X-Changer QUAD 480 Extreme Performance Radiator in your case & they require low rpm fans and they have great cooling..

I use 140mm rads and I would say the selection of 140mm fans is lacking right now (but not a deal killer.)

[Church]

Oh. I missed fact that tripple in question was for 140 mm fans :/. Well, anyway, someone already posted comparative test url

Get something that uses 120mm fans... you have a better selection available.

If you have enough space go for pa140,3 and use some custom home made fan adapter if you want 120mm fans , for example feser monsta is a 420 rad and many people mount 120mm fans on it...

also you can buy bitspower fan adapter 120 to 140

Check out skinneelabs for a comparison of the Thermochill 140.3 vs 120.3 . At least gives you an idea how the 140.3 compares - then you'll need to do some extrapolation to see where the 120.4 fits in.

Will the 140.3 fit in the TJ07 and still leave room for the PSU, etc. (not saying it won't just can't recall seeing one in that case). The 120.4 fits, lots of folks have used them. That would be my choice, given the fan selection available. And yes, you should be able to cool your CPU and GPU in the single loop.

Well if me check the surface areas of the two:

120.4: 120*120*4 = 57600mm^2
140.3: 140*140*3 = 58800mm^2

So the 140.3 radiator has (very slightly - 2%) more surface area while using bigger, slower rotating fans for quieter performance.

It should, 120*4 = length of 480mm excluding barb vs 140*3 = 420mm excluding barbs

Just a small note here in regards to that comparison.
The 140x3 may well have slightly more surface area, but you also need to consider whether 140x3 fans that you'll be using can push equivalent amount of air through the rad, compared to the 120x4 fans.

Well it also depends on the fans he's going to be using, a single 140mm will beat one of those cheap Chinese $1.50 LED 120mm fans

That's what I was saying.
I've just gone through the ppcs listing here on the 140 fans. There's not much choice of it at the moment.

I can safely say that, at the moment, using 140 will not get you that much higher performance benefit (no real high CFM 140 fans), and cost wise, total is about the same, accounting the higher cost of the 140 rad and considering you only need 3 fans.

When more producers start to fill the 140 line, I suspect you'll be able to get higher benefit on performance. Cause the current 140s are more concentrated on whisper quiet models.

So, if you can fit the 140, I'd say go for it.
You're only cooling CPU and GPU anyway. You don't need high rpm - high noise fans. By the time you're adding more stuff into your loop, they'l have better 140 fans that you can use.

Can't go wrong either way.

You're backing up what I'm saying - the noise factor

[The Shooter]

If you meant to have the rad in your case it will be troubulesome to fit any of them in.
