Single or dual loops

[joshcowin]

Hi i was thinking of having a cpu and gpu cooled and wanted to know which would be better a system where the pipes go from 1 to 2 pipes then one goes to cpu radiator then back to res/pump combo and other gpu and the same.or go: pump/res,cpu,rad,gpu,rad then back to res/pump.
Also what pump power would i need,would 750 lhr be sufficiant?

2.what fans would be best to push through a radiator,and what fans are best used in general (exhaust)

3.can you put fans on the inside of the case on the top pushing through air to the externals?
Thanks Josh

Depends on your radiator size but in general a duel loop system offers minimal performance gain over a single loop setup.

Corsair SP series or Noctua NF-F12 fans are both good choice for a radiator.

My rad sizes would be 240mm,okay i will look into those fans

If it is just a single/dual GPUs with a single CPU then having a single loop would be easier to maintain and performance difference between 1 and 2 loops is minmal when it comes to most of the "simple" loops.

Have a look at GT1450 or GT1850 fans as well. But you will have to put most fans on a fan controller so you can reduce or increase the RPM.


EDIT:
What CPU and GPU are you having?
Also what is your case?

Flow rate stated in the item description means nothing
Get a MCP355(with an aftermarket top) or MCP35X pump or D5(MCP655) pump.
FLow rate can change because of the way you set up your loop and of the components you use in it. General rule of thumb in many articles is to have 1GPM of flow in your loop for best performance - but I can tell you from my own experiences that you can have 0.2GPM of flow and have good temps!

not sure what CPU or gpu,all i have decided so far that its going to be Intel,the case is going to be the nzxt switch 810 or the bitfenix colossus venom.okay thankyou very much i will have a look into those fans and pumps
