9800x3D - Water Temp in NZXT Kraken Elite 360 AIO?

Asking for my friend who just built his rig 9800x3d with 5080 and NZXT kraken elite.

Playing games his water temp is hitting 43-47 according to the lcd display. Ambient about 27.5.

His cpu temps are fine in games about 70-80 but I’m not sure if his aio is mounted correctly or has too push paste but that seems really high to me?

I personally have a triple 360 radiator and run a 4090 in my loop but my max water temp is 36 but not really helpful because my gpu is in my loop. If I just do a cpu benchmark my water temp only goes up maybe like 3 degrees. So max of 33.

I know they aren’t directly comparable but for a 360 aio only cooling cpu surely that’s got to have an issue?

Hoping others with similar setup can help me figure this out before I ask him to remount his block.
