Hi everyone,

Im new here and Im start building my new home server. currently I use QNAP TS-873 as NAS and VM server and Supermicro 1U server with Intel Xeon E3-1220v3 & 8GB RAM as firewall(Sophos Home). On QNAP I have some virtual machines and most of them are linux based(One is Windows 10).
I have plan use Proxmox as hypervisor and passthrough two USB to one VM(HomeAssistant) and passthrough 2 HDD's to NAS VM(Probably TrueNAS Core) ...

I build my new server with next components:
MB: Supermicro H11DSi
CPU: AMD Epyc 7601
RAM: 8x16GB Hynix 2666MHZ(Supermicro certified)
LAN: Mellanox CX354
4U Rack Case IPC-E450
PSU: BeQuiet DARK POWER PRO 12 1200W
Storage for OS: 2x NVME 960GB Samsung PM983
Storage for NAS VM: 2x 8TB HDD
Storage for VM Backups: 2x 3TB HDD

I will also use(Still waiting them) 4x NVME 960GB Samsung PM983 in RAID10 for VM HDD images. And need to install 2 rear fan into case to remove hot air from case...

For test Im install Proxmox on old 250GB Samsung NVME and create Windows VM with 64 virtual CPU's to run prime95 and test CPU temperatures...

CPU temperature raise to max 58-59°C and then few(10-30) minutes later fall down to 53-57°C:

Idle temps:

So now I have few questions:
1.) What are max safe temperatures for Epyc 7601 CPU? Is still safe if go up to 60-65°C?
2.) What are max safe temperatures for RAM? On load they go over 60°C...

Here are few pictures of my build(In progress):

Have you got any other fans beside the one on your CPU cooler? Such cases tend to be designed for a forced (or at least forceful) airflow. Judging from your pictures, it looks like you're fully relying on your CPU and PSU fan, and I'd say for your peripherals that's a bit risky.

As for your CPU: it has a temperature sensor built-in and thermal limits will make it shut down before it fries itself. Besides, ou can set limits in the BIOS probably.

Hi @Borromini In front of case I have 2 CoolerMaster MasterFan Pro 120 AP(12CM) fans. Each of them at full speed produce 62.1 CFM(AirFlow) and 4.6 mmH2O(AirPressure). On back side I will put 2x 80mm(I will receive them probably tomorrow). Now PSUsuck heat from case which have 135mm FAN for cooling...

My pictures in first post didn't show real system state... So here are some other pictures of current state...

Front side of case:

Front fan(On other side is another one - I also need organize all cables):

Rear exhaust fans:

One of PCI-e cards with nvme for OS. Cards are redundant and all nvme's will be mirrored to provide redundancy:

Cards installed(2x 4port nvme cards, Mellanox CX354, PCI-e USB card for HomeAssistant passthrough):
