How many rad is really needed?

[duncan5200]

In the future I will most likely be making a custom loop for my pc, I have a 750d case, a 4770k, and a gtx 780 ti, and in a few months most likely will be adding a water cooling loop, now my question is hoq many rads is really needed, I run my gpu and cpu at stock clocks, in a few years plan to overclock when not enough perfomance, and the gpu is also stock, but I know that a water block drastically drop your temps on a gpu, now for this would a 360mm be enough, ro would I need like a 360 and 120, or like at most 360 and 240?

dual 120mm 45mm thick rad per component

[Stefano]

A 240 would be enough.

[duncan5200]

dual 45mm rad per component

Your talking thickness right? if so what is the system ran dual gpus does that mean a 360 240 and 120 would be needed?

A 240 would be enough.

So 360 is definetely good then?

[Stefano]

Yep, but bear in mind that the more radiators you have, the quieter you can get it to run.

Okay will it be whisper quiet with a 360 then?

If you went SLI, You'd be more than fine with a 360mm and a 240mm radiator.

 

Really though, you only need a 120mm 45mm thick radiator per component, and double that for overclocked components. (240mm 45mm thick radiator per component)

Well depends on overclocks and so on...

It depends how cool you want it. Cooling a 4770K and a single GPU, you could run static pressure optimized fans @ 700rpm and have nice temperatures.

I run 2 Titans and a 3930k on 360 + 240 just fine.

Just stick to the easy formula:

Rads =/> n x 120 + 120

n = number of components you're cooling.

[TheNinjaNextDor]

Get an XT34 for the top and Monsta or UT30 240 for the front.

Im still debating on wether going dual gpus or custom loop, because on or the other and not for a few months, but its good to plan prior, but if I went wc and had a 360mm x 45mm with corsair sp120 quiet editions, it would be quiet, and temps would be good and then add in another 120mm if I decided to go dual gpu?

This might be answered by the members above, but here's my reply.

 

For that system, I would buy a single 120.3 (360mm) radiator. Time To Live Customs cooled an i7-3960X and a GTX Titan with a single 120.3 rad and it was nicely cooled. Since you have a 750D, you might be able to install a 60mm 120.3 rad on the top. If you're not able to, you can put it in the front.

Seems like the best formula, if I go will most likely do that then thanks.

Thank you all for the help, I know have a understanding what to get when I will save up the money, thank you all.

[gigabyte]

240mm, I'd recommend 360 40-60mm thick tho if you want it to be cool and quiet

[beau]

I have a 240 30mm 20fpi at the top and the bottom.  If I'd do it again I'd get a 420 45mm at the top with low fpi, a 280 60mm low fpi in the front, and a 140 30mm low fpi in the rear exhaust.

The standard rule of thumb is a 120 baseline and 120 per component.

 

You are capable of cooling a rig on half that.

 

You want proof? A 280 with 1000 rpm fans cooling 3 780's and a 3930K,all overclocked.

This forum in particular advises massive over speccing of rad face,a 360 will be more than sufficient for your needs.

It worries me when I run my fans at 500 RPM on both rads, my CPU gets near 70 and both GPU's hit around 50c.    I wish I had a way to monitor the water temp, to make sure I'm not damaging my pump.

Not sure what an MCP-655 's max operating temperature is either..  I tried googling but couldn't find a definitive answer anywhere

 

(running at 1,000 rpm hits about 50-60c on CPU and ~40-45c on the GPU and running 1450 RPM on both rads is ~50c on the CPU and 35-42c on the GPU)

 

I've been thinking about push/pulling both rads so that I can leave the fans at 500 RPM without having to worry about that, I love the absolute silence , besides my dam HDD buzzing -.- probably gonna replace it with an ssd

[VSG]

Why don't you get a temperature sensor to be sure then? XSPC and Koolance sell ready-to-use kits that just need to be incorporated into a loop and have displays as well.

Those temps are still below what aircooling provides,why the concern? The pump is good for 60c of coolant temp,you will not reach that in use.

 

Your concerns are unfounded.

Zero overclocks, other then what gpu boost does on its on
