I’ve heard people get ~31k stock

Maybe there are power limits on that board

Also make sure you try and push your ram to at minimum 7200mhz

Something is limiting your cpu, should be around 39k stock (40k if your cooling is top notch)

You can build a custom loop for ~$150. Better performance than AIOs if done right but not going to look as good or crazy as those $1000 loops which are unnecessary
