Ryzen 7 1800x at 80-90 degrees while idle w/ 280mm AIO liquid cooler?

[theqwertymann]

I recently built my first PC after looking into it after some time. I decided to go with a Ryzen 1800x build. Here's my specs:

Case: CoolerMaster MasterCase Maker 5

Mobo: Asrock X370 Taichi

CPU: Ryzen 7 1800x

CPU Cooler: Cooler Master MasterLiquid Pro 280mm AIO Front-mounted Pull Intake

GPU: EVGA 1080 ti SC2 8gb

RAM: 2x16gb 3200 G.Skill Ripjaws V

PSU: EVGA Super Nova 750W G2

SSD: Samsung 850 EVO 500gb

HDD: WD Black Edition 4tb 7200rpm

OS: Windows 10 64 bit Home Edition

Monitor: Asus PG279Q ROG Swift 1440p 144hz IPS


After I believe I built it correctly (although now I'm starting to question it), I installed windows on the SSD, downloaded drivers for GPU and CPU, and downloaded Steam among the other basic programs like chrome etc. I played Team Fortress 2, Portal, Left 4 Dead 2, Mirrors Edge, and Fortnite Battle Royale and they all ran at around 10-30 fps, sometimes occasionally spiking up to 40 or 50 for a few secs.
After some research and trying everything, I couldn't figure out what was causing the issue. I then realized that my GPU and CPU usage was often under 20%. I turned power saving options off, enabling performance mode, and it helped my GPU a bit. But, I still got around 30 fps in games. So, I checked my CPU, and it still was around 10% utilization while playing games. I checked the temps, and I believe I found the issue.
While currently writing this post with the only programs running being Chrome with one tab open and coretemp, my CPU is at 80 degrees C. Earlier, it was at 93. I've heard about 1700xs and 1800xs having a false 20 degrees bonus for some reason, but even then at idle temps my 1800x would be at 60, which I'm pretty sure is way too high. I thought that my AIO 280mm liquid cooler would keep it really cool, but I guess not. Did I install it wrong, or is there something else wrong with it? Btw, nothing is overclocked. Thanks for your responses.

Either your cooler water block is not correctly seated, improperly pasted, pump is not working or something is not connected correctly.

Start over and verify that every connection is exactly where it is supposed to be and that the waterblock is firmly seated.

Something is wrong, those temps are NOT normal idle temps. Without being there to actually check it myself, my first suspicion would be that the pump is not running.

To add to what breeze said, try to verify that the pump is working both through the BIOS or a fan monitoring tool (to check the pump's tach reading) and through a personal inspection. Have the case open so you can listen for the pump noise when you first turn the computer on, and touch the tubing and/or block to see if you can feel the telltale vibration of the pump + flowing liquid. DOA pumps are probably the most common issue you'll encounter with closed-loop coolers, they'll either work perfectly from day one or not at all. If that is your issue, you were just unlucky.

Thanks for the replies! I'll try checking the BIOS and reseating the pump. Now that I think of it, the only time I heard water flowing through the pump was when I first turned on the PC. Since then, I've only heard fans. This is my first liquid cooler, so I'll look up references for the noise and check if I can hear them.

The pump is what I'd be targeting right now. If you cannot hear the hum of the pump running, with your head as close as you can safely get it next to it, and if there are no RPM readings from the BIOS or the CM monitoring utility telling you that the pump is actually working, then I'd stop running it immediately and contact CM for troubleshooting and potentially initiating an RMA.

Can you feel the tubing vibrate while the system is running? The pump should create a 'humming' vibration feel and might be possibly audible. If not, you will want to ensure the pump is connected to a correct power connector, either PWM, Sata or Molex, depending on the unit. I'm not aware that this cooling unit has Threadripper TR4 mounting support, though. Can you confirm this? Most of the TR4 CPU coolers are specifically being designed to cover the Ryzen/Threadripper IHS completely since it is quite large compared to other CPU sockets.

I reseated the pump, and reattached the pump connector and everything seems to be running fine. If I don't respond anymore, then it likely worked. Thanks so much for the helpful advice!
