I just recently installed a corsair h100i in my system which is replacing my zalman CNPS 9700. after booting and going into the bios, i noticed that my cpu temps were not as good as my Zalman. my idle temps with the zalman were around 28-31 C and with the H100i they are 35-40. under 100% load, running prime, there is a large gap between the h100i and the zalman where the zalman would never go over 50 but the h100i goes to about 65 . things I have tried are taking h100i off and replacing paste with arctic silver 5 and maxing the fans (sp 120's quiet edition) on the rad. The mounting of the h100i and backplate seem perfect and the pump is running at 2170 rpms (not sure if that is good or not). I am thinking about going back to Zalman but am hoping there is a possible solution to this.

I put about a pea size and spread it into a little square probably 1 cm x 1 cm and let the heat from the CPU spread the rest of it out. I used the same method on my Zalman heatsink. I guess what i am trying to ask is if it is worth keeping the h100i on or do i revert back?
Yes I believe so. I did opposite corners like you explain. One thing I did notice about the backplate is that when I tightened it to my motherboard it was loose until I mounted the h100i. I watched a video guide And that person had that happen with the backplate as well. I guess I could retry it if you think it would be good idea.
Thought I would add this too. I ran the p95 test using the max heat test all cores instantly within a minute went to around 70 and over. Used core temp to monitor.
ya mine is far from that. I just watched a review about the h100i and it said that the intel backplate was not measured correctly which causes the h100i to not put enough pressure on the cpu. he suggests using an older backplate such as the h100 one or extra nonmetal washers with the plate so i am gonna give that a go with the washers.
Well I added rubber washers to the backplate and tightened it using opposite corners and wow did that make a difference. running max heat p95 i am not going over 50 C on any core and and idling much lower.
