Theoretical radiator fan question

[AlC0]

Hi fellas!

If one must choose, would you choose thick radiator or thick fans (wich generates higher static pressure) ?

I have found a fan type that is only 15mm thick, and I wonder, will a deeper radiator be more benefitial than higher static pressure?

Here is the fan I was talking about:

Here is a noctua fan:
http://www.noctua.at/main.php?show=productview&products_id=65&lng=en&set=1

As you can see, the thicker fan has approximately twice as high statick pressure.

Will 10mm of extra rad depth be better or worse, and how do you guys think that will apply on my intended use as described below? I am mostly interested in how this will work in pull configuration.

I have a fractal design R4, with an i5-3570K and 2x Radeon HD 4890 cards that I will be watercooling this fall. I have approximately 50mm of space for the radiator in top of the case.
I will use the the front as intake, and the top as outlet (exhaust.) I will use 2x 140 mm fans in pull configuration between the rad end the case top.

Thanks in advance!

in your case without modifications you will be only possible to use thin radiator (27mm) on the top of the case with standard fans (25mm)... thicker radiators can be positioned in the front of the case.. also you are looking for 140mm fans.. i have to advice that in the R4 you can not mount 280mm radiator without modification and the more easy modification to make it work its in the front of the case or use 140mm radiator on the rear of the case..

about your question, the Noctua fan will perform better than the prolimatech but the prolimatech its more silent also its 4pin PWN wich its the ideal type of fans for radiators as you can easily manage the speed with your likes also its the best for push/pull configuration.. ..

Yes, I will have another 240 thicker radiator in the front, but i will need at least 2 radiators to cool 2 GPU's and a cpu. A 280 rad won't fin in the top spot for radiators?

Are you sure a 280 rad won't fit in top? This means I have to use a 240 thin rad witch will reduce my cooling capacity even further. I would have to add a couple of 140mm rads too I guess...

Anyway, your input helps a lot for choosing rads, thanks!

yeah bud, im sure that a 280mm wont fit in the top.. even the h100/h100i have some problems to mount specially with high-ends motherboards... check some reviews about the case and all the bad points or dislikes are the how hard its to mount a 240mm thin radiator on top.. most people just mount like this

this guy success with mount a h100 with some difficult..

this other guy success too to mount a h100i but pretty hard due to the motherboard 4+4 connector its little cramped by the radiator..

and the h100/h100i are pretty thin radiator....

i agreed with couple of 140mm radiators... 2x140mm radiators will work muuuuuuuuuch better than single 240mm or 280mm..

No, I would go with a thinner rad. The difference in rad thickness only makes static pressure more important. There are diminishing returns with rad thickness anyways. At the fan speeds that I like to use a thinner rad would probably be better anyways.

I see. I am going to overclock as hard as I can both the CPU and bouth GPU's. I have calculated that Thees three components will draw a maximum of 800 watts. I also guess that most off this energy will dissipate as heat. The computer will be standing in my girlfriends bedroom, so it needs to be pretty quiet.

I plan to mount an XSPC AX240 in front with fans in push/pull configuration, then I need slim radiator at 240mm in the top, and a 140mm in the back and bottom of my case I guess.

This is why I was wondering about the fan question in my original post. I have a h100 myself, and it is a pain in the *** to mount with that 4+4 power connector.

So here comes a follow up question: Will a single D5 pump be able to give me an adequate flow with 4x rads, 2x GPU fullcover blocks, a CPU block and a reservoir? Would you have split it up, or will it work well?

Is it really worth it to be water cooling a pair of 4890s? Seems like a waste. A single GTX660 should be much faster and doesn't need water cooling.

It would be more than enough, you could get a vario and even turn it down.

Well, it is not just the performace/price aspect for me. i like this hobby. I enjoy overclocking my components, and I enjoy watercooling. I will have a loop in my computer anyway, and the two extra waterblocks is just 40 dollars a piece, and I will have my next GPU underwater as well, so I think it is woth it for me personally. Also, the aspect of a quiet computer in my girlfriends bedroom is kind of important to me, as i sometimes sit on the computer gaming while she is sleeping. And as you may be aware of, those 4890 makes a lot of noise, and two of them I think will outperform the GTX 660.

Good to know that the D5 will handle the loop, thanks!

 

[BababooeyHTJ]

and two of them I think will outperform the GTX 660.

Not even close, on a good day they're about as fast as 6970 (probably closer to 6950). Thats probably a very, very optimistic guesstimate on games that scale very, very well on 4xxx series cards.

The 660ti is faster than a GTX 580.

Nvidia should also be releasing a GTX7xx series GTX670 rebrand which will no doubt cost less than a typical loop while being very quiet.

I guess you're right, I compared the cards at hwcompare.com. I might get two 560Ti cards out of two older builds with WC blocks Got to reconsider maybe, but I really like WC'ing And I don't get the same results on air...
