FX-9590 in NZXT Phantom full tower case red cpu temp problem help please

Hi there i have built a pc in a NZXT Phantom full tower case with the following spec:
CPU: AMD FX-9590 4.7GHz 8-Core turbo 5.0GHz
Motherboard:Gigabyte GA-990FXA-UD3 ATX AM3+
GPU: Asus Geforce gtx 670
RAM: 12Gb
CPU Cooler: Corsair H55 57.0 CFM Liquid CPU Cooler
Hard drive: 2TB
Power Supply: Corsair CX750
I have a fan set to intake on front at bottom i have 2 fans on side panel at bottom on intake i have the top back fan set to intake for the liquid cooling radatior and 1 large fan at the top set as exhaust.
my cpu temp keeping going high to the highst being 66c and i dont like it i want to keep it from going that high.
any help would be great many thanks. i would add pics of inside case setup but dont know how to (if anyone does let me know and ill post pics to help) thanks

also my core clock speed when playing games spikes from 4751.22mhz drops to 1433.21mhz then goes back up and during the 2 seconds in spikes my games lag and lose fps??

Let's get the obvious outta the way:

Is the pump on the AIO running?

Maybe a thermal past issue?

Edit: I know these are trivial but I've had myself having a melt down thinking the worst when it was something simple like plugging in a fan header or something.

stupid question how would i tell if the pump is running i hear like a liquid noise when i turn pc on few a few seconds.

and the thermal paste i am getting some more and redoing it to make sure.

The AIO unit you have there is a little small for a 5ghz AMD chip your speeds mybe throttleing due to heat try adding a extra fan to the aio unit

On my AIO cooler, I just put my fingers on it in order to check for (even the slightest) vibration. Or assuming your pump is plugged into a fan header, you may be able to check your UEFI to see if there's in RPM reading in there.

the pump is plugged into The PWR_FAN on the right of the board then adding another fan onto the radatior do i put it to intake air from the rad or exhaust to the rad??

If I recall correctly the H55 isn't really up to the task of cooling an FX-9590. I think you need at least an H75, or H80i?

Don't quote me on that, I'm not an expert on AiO units.

You can try putting a higher performance fan on there, but I think that just may help to mitigate the issue, not prevent it.

should i put the rad fan in the cpu_fan header and the pump wire in the pwr_fan header (the way i have it) or the other way round then change the bios for the cpu_fan hearder speed??

3 ways of doing this.

  1. take of the side panel stick a desk fan and blow into the case.
  2. ramp up the fans to breaking point
  3. get a better cooler.

Take out the fan above the aio unit all that is doing is interfering with the air flow to the unit then get 2 fans on the aio in push pull but dont expect very good results on a small aio like that ideally you need a H100 or a noctua nh-d15 to tame a 5ghz chip.

i was looking at getting a Corsair H100i Gtx would that do the trick? ty

Yep that will do it

can anyone tell me the diffrence between a CORSAIR H100I AND THE H100I GTX?? ty

GTX is the newer model

but both will cool the fx9590 the same ? ty

its newer than the H100i thats about it lol performance is about the same

which revision of that motherboard is this?
Also i dont think that the H55 aio, is decent enough to cool that FX9590

I use a CM Nepton 280mm on my 4770k. Like others have said, it may be too little cooling for that chip. I'm not all that familiar with AMD's line up these days.

well thanks for all your input guys im going to return my H55 and get the H110I and rearange my fans and hope it gets better :) ty ill be bk
