Fan setup for watercooling

[SeriuzBuzinez]

I am running a Alphacool NexXxoS UT60 Full Copper 480mm radiator with four Corsair SP 120 Quiet editions now my odd problem is that because of the cables being short they are plugged in to different fan headers and one set of fans is running at 1000rpm and the other set at 600rpm... now I have ordered an extension cable so I can access the other fan headers if needed so my question is what fan speed is ideal for keeping everything in my loop at decent temps and would there be any problem running watercooling with the current fan setup? I plan to get the other set of fans running at 1000rpm but until then would it be fine running with the current speeds?

This is really hard to say from the information you have given, we don't know what parts you have in the loop, if they are overclocked, what pump is being used and even if we knew that it would still be almost impossible to tell. I would say that the easiest thing for you is to experiment by yourself and see what temperatures you get at different loads and fan speeds. Since that is a massive rad i would say that a low fan rpm is enough but it completely depends on the hardware being cooled by the loop!

Oh yeah I forgot to mention my hardware Intel i7 4930k, GTX 780 Ti and will also be cooling the motherboard and my pump is XSPC Laing D5

 

Thanks for the advice, I guess I can only try it out and see what happens I suppose.

Alright, nice setup you have there! Just checked your build log and it locks wicked!

 

You should be able to get the system really quiet if that's what you are looking for especially when your not gaming. Are you are going to have a fan controller or a software to change the fan speeds? It is something that you should get. I have the same fans but I use the built in fan controller in my Node to change the speed. At 5V (not sure of RPM) you can't here the fans and my 3570k idles at 40C with a Antec Kühler H2O 620. At the max speed (12V/1450RPM) the fans are quite loud, but it seems like you are going for lower speeds. Good luck on your testing and I look forward to seeing the end results! I started following your build log

Thanks for the kind words!!

 

Yeah I am going for a nice balance between silence and performance to be fair, I will probably overclock enough so I can easily keep the temps and sound low enough so it's quieter than the intel fan... which is really loud at the moment. I will probably get a fan controller later on down the line at the moment I can control the fan speeds through temperature levels in the BIOS but sadly it don't let you set the fans to a specific rpm... which I think it a bit silly but ohwell

since you are using one fan set, then between 800-1200rpm should be enough for

a CPU/GPU holding a 70° on the CPU and 45° on the GPU with standard overclocks.

 

ideally is the lowest with best temperatures. lowest speeds provide low level noise.

Thanks for the reply, I now have the four fans running at 1000rpm so now I feel a lot more comfortable knowing I should have plenty of headroom
