I completed my first build(http://pcpartpicker.com/b/M1y) a month or two ago and at first I had trouble getting "normal" temps(idle 40-50C, load 70-95C), but after a few reinstallations of the H100i cooler and Arctic Silver 5 thermal paste, my build was running stable(idle 26-30C, load 55-65C).

For a month or so, my build ran with normal temps, but recently they have reverted to the higher temps and I have not been able to get them back. I have reapplied the thermal paste using different amounts and methods (line/rice method, small amount, pea method, small amount, etc.)
When playing CS:GO on max settings, for the first 5 minutes my average temps are about 65-73C and after 5 minutes the average temps are 77-88C.

I can only run prime95 for about 10-15 seconds before the temps reach 100C. Guys, I'm out of ideas, I made sure that my H100i is pumping normally under load (2300+ RPM) and my 240mm radiator fans are spinning normally under load (2000+ RPM).

Any suggestions? I bought the H100i off of Amazon and I am now outside of the 30 day return window.

Just ran prime 95(Small FFTs), temps got to 98C in 3 seconds. Touched the tubes and they were not noticeably warm. I'm assuming this is because the test only lasted 4 seconds before I stopped it.

*Let me also note that I am using Core Temp 1.0 RC6 to monitor my CPU temps.

@sunder25 Ok, for the first 5 or so minutes the average temp is 66-74C. (the temps go 10C high in intense combat)
After 5 minutes the average temp is 74C-80C (temps got as high as 93 at some points). I will also note that the load for any core never got higher than 65% at any point.
 
Okay that should not happen even with stock cooling.
And the cpu is on stock clock with normal turboboost?
If the heatsink is properly mounted, then the problem has to be the cooler.
I am sorry, I can't help you with that i don't know enough about the matter.

If i were you though, i'd make sure the radiator is above the cpu level, and
that water is flowing through the tubes.
