Purchased a h100i refurb from frys for $70. It was refurb from the company and was packed/looked like new. this was installed on a 4670k which is set in an Asus z87-deluxe with 4 way optimization (1 click overclocking). (ps, stock h100i fans have been replaced with noctua nf-f12 fans)
4wo (4 way opt) takes my CPU to 4.5ghz with this cooler, but does not keep it there when i am transcoding mkv files to blu ray using MultiAVCHD, i end up getting a blue screen.
i dropped it down to 4.1ghz and i am running fine, i might be able to get 4.2-4.4, but dont want to waste hours transcoding to find out it will blue screen half way through.
my main issue with this setup, the corsair link software. you can set custom curves for your fans to rev up to X speed at X temp. BUT, the software only lets you use the h100i temp, NOT the cpu temp.
this is the issue, the h100i temp might go up 5 degrees when your cpu temp will jump from 32-65 degrees. it took me a while to figure this out, and i had to set my fan curve accordingly. at first i had my fan speeds go up at 30,35,40,45,50 degrees (based on h100i temp), but the h100i never reached those temps. now my corsair link settings are more like 30,31,32,33,34. corsair link also offers NO adjustment on the pump speed, it is always on 1 setting.
4wo lets you set fans to cpu temp, i wish corsair link did too. though, i did read in multiple forums that the temp of your cpu is minimally effected by the speed of your fans on the radiator. so having them on slow to max might drop it a couple degrees.
i guess i wish there was a better way to integrate Asus 4wo to work with the h100i. What are your guys h100i settings in corsair link, maybe mine or not the optimum?
Currently i have been transcoding movies for a couple hours @4.1ghz:
CPU temp: ~60
h100itemp: ~30
h100i fan speed: max, about 1,400rpm each (manually set to performance mode in corsair link 2)
cpu cache ratio: 38x (not sure what that is or means) (in asus 4wo)
cpu voltage: set to adaptive - currently 1.275 (in asus 4wo)
