Fans on radiator? 2 or 4?

post #1 of 10
Thread Starter 
So, I just got my swiftech apex ultra + kit, and the radiator only comes with two fan on it and take are intake. If I add two more fan on it and act as a exhaust. Will it help my temp drop more or not much diff in temp?Also, by adding another 120 radiator after the the chipset, will it help?

res>pump>rad>cpu>chipset>another 120 rad>gpu ---planning on it

Will ther second setup help?

Sorry, I am totally new to wcing setup.

1) Putting 2 more fans on your radiator will not help at all.
2) Putting another radiator in the set-up will help cool the GPU further, but this will put a bit more strain on the pump, so make sure it's up to the task.

Personally, I wouldn't bother putting another radiator in the loop, as a safe limit for GPU's is 90C.

I've heard there's not much point watercooling your chipset. Best off getting a decent aircooler for it.

Sorry, I am totally new to wcing setup.

Some people say having there fans in push-pull (4 fans) help there temp's a lot, I've never tried it so I can't really say.....Try it and see if you want to, try running with 2 see what your temps are , then add 2 more and see if it helps......

There really is not much need to WC your NB... Just get a good active NB cooler....You could add a second 120 in your loop but I don't think you will really need it, the Swiftech 655 or Laing D-5, same pump would be able to handle it...

I would just try it with what you have and then if you are not cooling everything as well as you would like try some different config's...The new Black Ice GTX is a killer rad if your not satisfied with your temp's I would replace the Swifty rad with one of those before I would add another 120 rad....

Use the first idea

the water really dosent heat up when it passes the CPU waterblock

it heats up after passing over it hundreds of times

a little rad in between would be pointless and could even hurt your temps becasue of lack of flow

If you have to overclock your chipset and Raise its voltage that is when you may need Water cooling. Well IMO i dont think adding a few more fans will help as much as adding a bigger radiator or perhaps another one.

There's going to be a jungle of tubing in your case if you plan to WC your chipset, GPU, CPU and still have an additional rad. Plus, keep in mind - the more connectios you make, the more places for leaks to occur.

Radiators by far are the most restrictive part of a loop. Adding another small radiator probably will not help and may actually hurt performance due to reduced waterflow. Adding additional fans may help... but before that, make sure to have a 1/2" to 1" shroud for your current fans. Personally, I am running eight fans on my quad 120mm heatercore. The push fans have a 3/4" shroud and the pull fans have a 1/4" cleareance. This allows me to run them at low speeds and still overcome the back pressure.
Once again...

1. Having 4 fans instead of 2 will help. It's might not be more than a degree or two.

2. Adding a second radiator will only cause your loop to have more restriction (along with a chipset block) and decrease your overall flow. The best way for a setup to funtion properly is having 1 good radiator, CPU/GPU blocks and stick with air cooling on the chipset.

Heh, just out of curiousity I took the fans off of my radiator just had it siting there. At my current settings I ran at arround 70° under a heavy load with this for air cooling. With no fans on my radiator I never got higher than 38°. With fans I've never seen over 32°. i am seriously thinking leaving the fans off. Though I am about to include my GPU in my loop, so now there will be more heat to get rid of...
