Best 240mm- 280mm CPU liquid cooler + fans for radiator and case

[UKHirst]

Hey guys, i'm looking at getting the Corsair Obsidian 750D full tower case and was also considering upgrading my cpu cooler from a h80, I've been looking at the H100i's that are 240mm and 280mm but don't really know which ones the best, plus i know there are over good brands out there for coolers apart from corsair.

I was also wondering about what fans to get for the case and also replacing the ones that come with whatever cpu cooler i get. I have been looking around at the AF and SP fans from corsair and like the look of them, but noticed they are not PWM, would i still be able to control the speed of the fans on my motherboard if they are not PWM? and are they any good?. Also could anyone recommend a good PSU that's around 800w?. Thanks

Any ideas?

I am currently using a Corsair H100i and have no complaints. I switched the fans with some SP120's from Corsair and I'm keeping my overclocked i7 3930K below 38C at idle, not much more than 40-50C at load. I am about to update my system to all Noctua Industrial 140mm iPPC-PWM 2000 RPM fans, so I will need a 280mm radiator cooler, but I am thinking heavy on a custom loop which will bring down temps on two 980ti's and a 5820K. The corsair fans might be a cheaper option for you however. As for a power supply, I would recommend a Corsair AX860. It is a fully modular unit, and has an 80+ Platinum certification.
