ok guys i have a big question if i make two loops my cpu on one and my gpus one one will it be cooler if i its allo ne one loop and hear is a few questions on this fourm http://www.tomshardware.com/forum/id-1661848/loop-loops.html
First of all if you've read through this thread from the beginning you're not asking a traditional radiator water cooler these questions however after looking at your thread link here's some advice for you to consider.
Overclocking has everything to do with end cooling performance results, many are under the delusion that water cooling will solve your heat problems produced from overclocking when in fact traditional water cooling using radiators is still under the mercy of ambient room temperature.
The additional overclocking load temperature has to be dissipated which means you have to have more radiator area to handle it, many think these handy dandy kits are going to be a resolution cure all when in all actuality they're far from it, understand I'm sharing what I have learned the hard way so you can glean what you want from it, don't expect me to give you a buy list.
Loop wise you only need two loops when you run more than one graphics card running full coverage water blocks, as full coverage water blocks are also cooling the voltage regulators and memory chips and they add heat to the loop too.
I would recommend a GPU loop with full coverage water blocks with 2 GPUs on a minimum of a quad 120 radiator and even that much radiator space is still limited when you overclock the GPUs but you can still enjoy load temperatures around 35c below the stock GPU air cooling.
I am basing that statement on my present GPU cooling setup and performance level of running two 580GTX in SLI with full coverage water blocks.
Radiator cooling IMO is the best route to take cooling GPUs, the most direct advantage results are clearly obvious by water cooling GPUs especially with full coverage water blocks, giving you the advantage of overclocking even overvolting without worry.
CPU overclocking with todays CPUs have reached heat levels that have to be compensated for and CLC water coolers and low end and mid range water cooling kit levels are no better cooling options than the High end Air Coolers.
A kit may seem to be the way to go as they are priced attractively but usually end up only having pieces of the kit reusable down the road when you discover the kits limitations when it comes to overclocking the CPU.
My best advice is research yourself and avoid someone else recommendations of this is the kit for you, as 9 times out of 10, overclocking wise they're clueless, or don't really want you to make a better purchasing decision because misery loves company.
No matter what you decide to cool if you'll be going the traditional radiator cooling route, it is imperative you have enough radiator area to cool with, the size of the radiator has everything to do with the end cooling performance especially in an overclocking environment.
A 120, or 240, or 360, or 480, single radiator has only so much cooling capability even the differing FPI ratings all have limitations, and once you pass those limitations, the radiator just cannot do any more for you.
I hope you got something out of this, Good Luck! Ryan
