Liquid Cooling Help

[thethink3r]

Hey guys I need your help. I'm building a PC and I intend to overclock my CPU and GPU as far as I can while keeping the temps as low as possible. I have £500 to spend and I was wondering if I could build a great loop with it. I've chosen a Phanteks Enthoo Primo V2 which allows for up to 2x 480mm 60mm Thick radiators in push pull so there's plenty of wiggle room. If I go with a Corsair Carbide Air 540 it'll leave me with roughly £600 but I don't think Id have to spend that much on a loop to get really good temps (please advise me on this though). I was thinking of getting an Alphacool 480 D5/ut kit (http://www.watercoolinguk.co.uk/p/Alphacool-Cool-Answer...) and then getting a full cover waterblock, some more coolant, more fittings and tubing, fans and another radiator to cool both my gpu alongside the cpu (which the kit covers). I'm not sure though, if this is the best way to do it (if it is then please guide me to which parts would be best). Here's a link to my system: http://uk.pcpartpicker.com/p/nzWXBm

I realise that after a certain price point you might be paying lots more for just a few degrees change in temps but I'm definitely staying far away from CLC and AIOs in general. I might get a 980 ti if the price isn't too ridiculous when it gets released (apparently this month) so I might get a custom air cooled one(it's been said that the reference cards and custom ones are getting debued at the same time) or get a smaller radiator and less exciting fans to fit my budget. This decision is also where I need your help.

Thanks.

Edit: If you could find the components from their UK sellers, it would be great because even though I can convert the prices into dollars, things are more expensive here.

500 pound is quite enough to set up the loop but you don't really need 2 480 radiators (if you are planning to do that). A 360mm and a 280mm would be fine for a cpu and 2 gtx 980 in sli to be honest. You would be saving some money.

I'll consider what you suggested But would you say that I could get low temps while they're both very highly overclocked

with a 360 and a 240?
