So I bought an H100i GTX and I mounted it in my case and my temps are idle about 47 degrees. I know that is really high for an aio. When I'm in benchmarks I'll get 70-80 degrees and I start to panic a little bit. I even have aftermarket fans on my rad, it's mounted in my NZXT S340 in the front. Now I thought it was a mounting issue because when I put the backplate on and screwed in the long mounting screws, it had a little play which I read in some places is normal. I use arctic silver 5 thermal paste so it cant be that. I screw down the screws tightly to make sure it's not that. Then I tried to use some spacers to put between the motherboard and the backplate so there was 0 play then mounted it and tightened everything down and it seemed to make it worse. But previously I was going through Corsairs software Corsair Link to see if the pump was working and it says its turning full speed, set it up like that to see if it'd make a difference, nothing. But I noticed that I could set it up to where I could have the rgb color change at a certain temp and I set it to turn red at 70 and purple as normal and I'd purposely stress the cpu to heat it up and it would never change color.

Can I please get some insight on whether I should just got back to my 212 P/P?

A couple of things: (1) what is your CPU? and (2) it sounds like you're suggesting you haven't mounted the AIO correctly.

Depending on the CPU, the temperatures you mentioned may or may not be bad. If Intel then they do seem high.

If you believe there's a mounting issue, then remount the cooler. It sounds like you're not completely convinced your cooler is mounted correctly, so that seems like an obvious place to investigate.

I am unsure about the last part you mentioned as it confuses me. You set the RGB so it would change to a specific colour when it reaches a specific temperature, but it doesn't. The purpose of this is to see when the CPU was reaching an unsafe temperature. You may want to use a software monitor to check on temperatures to see if it matches what you already use. It would also depend on the circumstances in which you're reading these temperatures. You mentioned benchmarks earlier and they tend to be synthetic; so they may differ to real world use scenarios.

I must have misunderstood the software, I thought it was supposed to change color when it got to a certain temp, which I set to 70. I use HWMonitor and I was stressing the cpu using cpuZ to see if it would chance and no dice. I'm using an AMD 7870k OC'd to 4.5ghz. And I did remount the cooler multiple times, and I tried using different backplates to see if I used the wrong one. When I lift up the block it only seems like a line down middle of it made good contact with the cpu, and the rest when pulled off looks like mountains and thick. http://imgur.com/rNZKy0a, like this, but less thermal paste, and not as perfectly cut in half.

AMD's older CPU's tend to run hotter so those temps aren't horrible. Also, it should be noted that AIO's should only be hand-tightened. Basically, turn the screws with your hand and wait for it to stop. You may be seeing that weird thermal paste build up because you're squeezing it out.
Also, are your aftermarket fans PWM? Also, can you hear the pump working in there?

I can hear my pump, I disconnected everything but that, but it does turn, I can hear it. Also, the two fans on my rad are the Corsair Air Series AF120 Performance Edition CO-9050004 WW. Is it a bad install? Bad fans? Hot cpu since its amd, or are my temperature softwares lying? And I undid my screws and hand tightened them only.

Those fans are not PWM and are likely the cause of your elevated temps. PWM fans will adjust speed depending on the heat your CPU is putting out to better cool it. You should replace those ASAP with SP120 fans by Corsair (SP is for static pressure). The AF series are for case intake and exhaust. Just throw the stock fans the cooler came with back on there as they are PWM. I would know since I have the same cooler.

Jwpanz is right about AMD CPU temperatures. And I should mention using AMD Overdrive to check your 'temperatures'. It's the only accurate software monitor and it uses thermal headroom rather than temperature. But from my x4 760k readings across various software monitors, then what you report wouldn't concern me.

And since other software don't read AMD CPU temperatures correctly, it's probably why your setting for the RGB change didn't work as intended.

So you're saying I can only correctly monitor my temperatures from AMD Overdrive? And I did notice a lot of softwares don't monitor it correctly. Can you tell me how to do this? I have two systems, one with the radeon crimson software, and one with the catalyst control center? Unless the process is the same.
