Consistent problem with water coolers

[Jimius]

A few weeks ago I bought the H100i GTX for my computer, after installation I would experience a thermal shutdown after about 20 seconds (75°C). I thought it was a problem with the cooler and sent it back to be replaced. In the meantime, I reverted to the stock cooler and my pc continued to run as normal. Then after a few days, a new cooler arrived (same model) I installed it, and its doing a thermal shutdown again. I'm at my wits end here. There are zero help guides for installing this cooler onto an AMD chip on the internet and the manual seems to have several mistakes in it. Im plugging the cooler into the cpu_fan header but Ive also tried plugging it into the power supply which didn't help. The block is definitely pumping as I had felt with the last cooler (even though I returned it just to be sure). Lights are on, fans spinning, slight vibration on the pump block and the sound of water. There is good airflow in the case. My suspicion is that the pump block is somehow not making proper contact with the chip.

N.B. In the Bios it lists the fan speed at around 750rpm. Im not too sure what this means

Amd fx 9590
Asus m5a78lm/usb3
Corsair H100iGTX
Corsair CX600W
NZXT H440 (case)

You're motherboard doesn't support that cpu,get a better one.The vrm's will get too hot which makes it shutdown.
You could buy the FX 8350 too,return the current cpu,but overclocking is still a no no so a better motherboard is the solution imo.

It does though, I was using it over the past few days with no problems

Check for yourself,
https://www.asus.com/nl/Motherboards/M5A78LMUSB3/HelpDesk_CPU/
under the specs it says;"cpu's supported up to a tdp of 140watts" your cpu has a tdp of 220watts.

If you are running with no problem using the stock cooler, why do you need the liquid cooler?

Then why was my PC running fine for several days even during gaming/rendering

It's not a good idea to run a higher tdp cpu than what the motherboard can handle. Even if you get it to 'work' you'll have issues sooner or later. The aio cooler cools only the cpu socket, the stock cooler is a top down cooler that at least helps blow air over the vrm. Weaker vrm (power regulators for the cpu) are already a typical problem for amd based systems even for many boards which do list support for a 220w tdp cpu. By using the aio, even though it's cooling the cpu itself it's allowing the overstressed vrms on the motherboard to heat up and thermally shut down.

You need a proper board for that cpu. The 9590 is already a mini chernobyl and you need to pair it with high quality hardware to take the heat and power consumption. If the board isn't suitable for an oc'd 8350, it won't work for the 9590 which is in essence, a factory oc'd 8350. You're welcome to run your hardware as you wish but consistently over stressing the components on the motherboard will almost certainly cause it to burn out much sooner than later. It's a 4+1 power phase board and most times people get into trouble trying to save money. A balanced system is important, trying to run a $220 cpu on a $45 motherboard isn't very balanced.

You need a board like this asrock 990fx extreme 6 with 8+2 power phases which states support for a 220w tdp chip and specifically mentions the 9590. It's currently on sale with a promo for $114 after mail in rebate, normally $140.
