Is your i5 overclocked? Those temps seems abit high to me for a H100i. I would check the default voltages your motherboard is delivering to the CPU. My Asus board wanted to give my i7 4790K 1.35v to auto overclock to 4.7Ghz, which caused extremely high idle and load temps. I have manually tweaked it and now it's running stable at 1.19v with an idle of ~37c and load of ~77c. This is with a Noctua C14 with the P12 fans.
