[SOLVED] Broken pump?

[cloydpakinggan123]

Hello everyone! Recently, I just bought a kraken g12 and Corsair h55 cooler for a Rx580.

My goal was to quiet down the GPU as it would sound like a jet engine at 60% fan speed. So I bought the nzxt bracket and water cooler from what Ive seen in YouTube videos. I've installed everything correctly, following a guide.

Main problem: As I launch the computer, I see the GPU idling about 70 to 75.. what.

Possible causes: I am using the system fan header on my mobo to power the Pump and the 2 fans. ( I saw that it'd work fine if I set the rpm to full speed.)

So far, one cooler pump runs hot but the other seems to be okay. Then I took out everything, to test if I could hear the pump working and I could hear noise from it, so I'm assuming its also working.

Please send help, before I lose my sanity

One header on the motherboard shouldn’t power a pump and 2 fans. Move the fans to a different header or directly to PSU with 4 pin molex.

Sorry, how do I connect it to the PSU?

A lot of what you can do for setup is determined by what you have.

Many modern bios can change where they read temps from, the address for the sensor. If thats the case, it's possible to connect a sys_fan header to a splitter and power both fans (one on gpu, one on radiator) by setting the header to respond to gpu temps.

Or, you can get a gpu/fan adapter and power both fans directly from the gpu, which controls the fans according to its own temps/firmware/software.

Either way, the pump can be set from any 12v power source, be it molex, Sata or header as it'll need full power always, the only benefit to using a sys_fan header is that you'll get to see the rpm of the pump in monitoring programs.

The pump should be seperate from the fans if you want any control whatsoever over fan speeds, or can be powered directly from the psu by a 3way adapter to molex/sata. Just not by header as that puts a lot of strain on the 1A power capacity of the header.

3 pin fan to 4 pin molex power connector

Quick update: I bought a molex adapter and is connected to my PSU. Both pumps feel cold and seem to be working, but my GPU is still running hot. It ran 80 to 85 and then worked it way up to 94s and shut off.

I'm sure I tightened all the bolts correctly. I'm not sure if you have personal experience with water cooling GPU but some insight would be nice.

Are you using this as an exhaust option? Single 120mm radiator is still not a great cooler but you should be getting better temps. First you need to make sure your pump is running full speed. What is your full system specs? What CPU and cooler? Case and fan setup? Need to know as much as possible.

Specs:
Ryzen 7 2700 (stock)
Gigabyte b450m ds3h
16gb ddr4 (2666) Corsair
Rx580 armor 8gb
Corsair h55 + nzxt g12 bracket
Cooler Master q300L mATX
3x noctua fans
Phanteks 600w psu

And I am currently using it as a intake config with the noctua fan. Also, I did as you said by connecting it directly to the Power supply with a molex adapter.

2 intake fans, 1 exhaust all fans connected to a fan hub.

Although, I was testing for the pump with an open case.

There's only 1 temp sensor on 90+% of gpus, and thats in the chip itself, ans since that's now no longer tied via heatsink to the VRM's/vram, then it's the processor alone that's overheating. Leaving 3 possible conclusions if the pump is quiet and not producing gurgling sounds. Either it's not making good contact with the processor or pump is toast or the fan isn't ramping up beyond idle speeds. With it moving coolant as it seems to be doing, that leaves the former or latter. If it's not making good contact somehow, this could be due to a bad paste job, like large airbubble, could be old paste that's dried out too much, could be the wrong standoffs, bracket upside down etc. If it's the fan not spinning up, that'll be on you to figure out whether or not it's running fast enough to apply decent sp/cfm.

It's really hard to say what's what, kinda in the dark.

The NZXT page says some AMD GPUs need a special copper piece to have proper connection between die and cooler
