Enough radiator area?

[fredrikstorm]

Hey guys!

 

I'm plannig a new build and have a few questions about radiators in this specific case.

 

The plan is to build in a Case Labs S3 with a 4790K and a 780Ti. Top that off with a D5 pump, solid tubing and windows on the top and both sides. This means that I'm going to have one radiator in the front, that's it except for a rear exhaustfan 120/140mm same . So now to my questions:

 

Will an Alphacool 280mm rad be enough to cool the cpu and gpu? I'm going to use Noctua NF-A14 IndustrialPPC-2000 PWM, although at sub 1000 rpm (hopfuly closer to 500).

 

It's going to be very tight, like demonstrated in this picture from awsome kimoswabi at overclock.net http://goo.gl/FS8tbI.

 

The two options I seem to have is:

 

1. Alphacool XT45 with push-pull

2. Alphacool UT60 with push

 

Which one of the above will make most sense?

 

Is it enough radiator area/flow/swag?

@fredrikstorm I'd go with the single 60mm deep radiator. Push & pull isn't required when you got a great set of fans. Nice pic are you going to submit your build log to be showcased in the now monthly build of the month?

i dont think the industrial fans of noctua go that low because, well, theyre made for industrial use and noise isnt a problem there.

 

@500 RMP that would be cutting it a bit close, but a thick 60mm with +-1000 RMP static fans will do the job nicely

Thanks for quick and solid reply. I will surely be posting a build guide when this happens, although we're talking autumn. Now I'm in the state of planning every millimeter of the build and going through all the options and possible obstacles.

Accordning to Noctua 500 rpm is their lowest speed. This is cut out from the specification of the fan on their website 

Min. Rotational Speed (PWM, +/-20%)   500 RPM

I hope it goes extremely well I also plan on WC + Hard piping 2 crazy systems together which I'm planning on. It's gonna be a freakin' huge blast XDDDDDDD!!!!

Go with UT60 and single fan, you will probably need to run it above 500 RPM and I wouldn't recommend Noctua Industrial fans.

 

That and your 120/140mm rear will be enough for an i7 and 780TI.

Take a lot of pics, and show us! Two systems in one loop sounds nice, and a bit more sane than LTTs plans with the outdoor radiators =)

Ok, sweet. What fans would you recommend? Are there any fans out there with higher static pressure/dBA?

Might be sometime but I'll give you & a lot of other members a PM to show my elusive magnificence

A 280mm radiator even in push/pull isn´t really good enough for a GTX780 Ti and the CPU... maybe if it´s just a showcase and if you don´t overclock and don´t run it very long. But let me tell you this I´ve got 2 custom watercooled loops in my machine and I used to have 1 GTX 780 Ti in a loop with a variable Swiftech MCP655 (D5) and a EK 45mm 360mm radiator with e-Loop NB B12-4 (now I´ve got a GTX 780 Ti 2 way SLI with a external Phobya 1080 NOVA radiator and 180mm fans). Temps and noise were acceptable, but I wouldn´t have wanted anything more in this loop with that size of radiator and fluid reservers.

 

A fan at 500 RPM with this small loop isn´t really working out either. Your temp Delta will be just bad. And watercooling and limit yourself with overclocking (with this size any good CPU aircooler will run cooler and OC better than that) doesn´t make too much sense since a custom loop isn´t really cheap.

 

As far as the math goes: 1x 120x15mm radiator surface can cool 100 Watts. A 140x60 (and this setup requires better fans than the one you want to get because you´ll need high static pressure fans) should be able to cool 150 Watts.

 

Your GPU has a TDP of 250 Watts (but spikes are very likely in demanding games) and your CPU has a TDP of 84 Watts... nothing OCed. And you should always have some reserves left with that being said 100 Watts radiator surface+ is recommended for OC and make it quieter.

 

Sure choice is yours and lots of people will argue about that but I have years in expirience when it comes to water cooling and I wouldn´t want to listen to people that just do theory crafting or dream about a watercooling. I am just writing this, that you are aware of what you will be ending up with.

@Najuno is right. A single dual 140 just isn't enough for an OC'ed 4790K + 780 ti. The lower the DeltaT/fan rpm you're aiming for the more rads you need. A triple 120 UT60 can dissipate about 210W w/ 1400 rpm fans. You're probably looking at about a 400W max heat load with your CPU + GPU overclocked give or take. A comfortable setup would be a triple 120 XT45/UT60 + a dual 120 XT45/UT60. Push or pull would be enough.
