[SOLVED] AIO help

[dan.monger]

Hello all,

I have been building computers for years now. However, I have never ventured into any water-cooling until now. I figured I'd dip my toes into water-cooling with an AIO, so I went and bought the NZXT Kraken X63 280mm rad. It's cooling an R7 5800x in a LianLI Lancool II mesh case. It's currently front-mounted since it didn't seem like I had the clearance to mount it on top with the front panel connectors being in the way. Now on to my issue. When I run Cinebench, I am running right at 88-89C, sometimes hitting 90 and thermal throttling just a tad. According to Hardware Monitor, my water in and water out temperature is 102c. What am I doing wrong in this setup?

Are the fans on your rad mounted as intake or exhaust? Mounting your fans as intake (so they take in fresh air from outside your case) will lead to cooler liquid temps thus lowering your CPU’s temp. If your fans are mounted as exhaust they pull hot air from inside your case through the rad and then out the front of your case. It is possible this is the reason your getting such high liquid temperatures. If your fans are mounted has intakes and you are still getting unacceptable temps, check the airflow inside of your case. Make sure you have your intake and exhaust fans oriented correctly so they don’t create turbulence inside your case.

The fans are mounted to the front of the rad, the fan blade direction doesn't matter does it?

Not necessarily, just remember that the fan will blow air in the direction opposite of it’s face. In other words the fan will take in air form it’s face and blow it from it’s caged side/back. Make sure that the face of the fan is pointed away from your rad, so the fan is blowing air through it. Did you have any cooling problems in this system before you introduced the Aio? If not it’s possible you have received a faulty aio. Below is a diagram of a fan’s airflow.

Don't use Hardware Monitor with Ryzen 5000.
Use Hwinfo, Cpu(Tctl/Tdie) instead.

The rest would be guesses since we weren't there watching you install the pump head on top of the cpu. You've been building for some time, but mistakes can still happen, yes?
-thermal paste did not cover the whole IHS. The dies underneath the IHS on Ryzen 5800X are offset from the center, unlike on Intel's cpus.
-pump head not seated correctly. You likely already know to turn each screw a little at a time though.
-NZXT CAM is required to control the pump speed. 80-100% is recommended.

Ah thank you! installing NZXT Cam and changing the cooling profile to performance kept my max temps to 80c t the highest. Much better. And it accurately shows my fluid temp at 28c.

Better, and more accurate.

Everything else being equal, make sure that pump is running at full speed.
