I just bought a Corsair H55 and it took me two hours to install due to the instructions being complete trash, but after I installed it i just ran I prime95 test and idle is high 20's and load it max of 52c for a I5-4460. (Got this cooler from a friend) Are these temps normal and should I put my pump on my cpu fan header 1 and my rad fan for system fan (I currently have these) or these harmful to the pump. I heard if it doesnt always run on 100% pump speed it will burn up. I need answers. Thanks.

No. Don't do it that way. Corsair instructions say to put pump on the cpu_fan header only to cover the event of pump failure it'll ring out as no cpu fan and the system will immediately shut down or fail to boot. Chances of this happening are remote. Putting the cpu fan on a system header means you have zero control over the fan since it'll be controlled by a system temp not a cpu temp.

Best setup is to either do as corsair suggests but run SpeedFan to change the headers so the sys_fan is controlled by the cpu temp and cpu_fan is 100% or install as normal, using the Cpu_aux for the pump (runs constant 12v for most boatds) and cpu_fan for the fan. Either way, the cpu fan needs control by cpu address, not sys address. As far as pump...

Thanks for the quick reply but do I plug my CPU fan that came on the rad into the CPU_FAN header on my mobo and then plug the pump into the SYS_FAN header on my mobo, for the best results?

Either way, the cpu fan needs control by cpu address, not sys address. As far as pump failure goes, SpeedFan has alarms, as does windows and other fan software so if temps start climbing, you get warned. A cpu will take a few minutes to overwhelm a defective pump and raise temps too high, so you will have time for shutdowns. Barring that, the cpu itself has a thermal limit and will throttle if overheated, then possibly shutdown. So no worries either way.

My h55 pump is on Cpu_aux, the fan is on cpu_fan and it runs like a champ, silent at idle, 900rpm at max (still almost silent) 33° idle, 70° at 100% prime95 v26.6 small fft after 1/2hr at 4.2GHz OC on a i5-3570k.
