Hi all,

 

I run UNRAID on a SuperMicro motherboard with double build in 10 Gigabit network adapter. I have no idea what a normal temperature is for a network adapter but I think that my temperature is really high (between 69 and 75 degrees). I this normal? anyone having experience with temperatures of onboard network adapters?

 

I build my board in a blade case with a lot of fans in the front, so there must be enough airflow, you would say. If the server is doing nothing the temperatures are around 55 degrees.

I put a small noctua blowing on the dual 10g in my supermicro so it stay at between 45-50C during load.
They can get crazy hot fast and even shutdown when too hot.
Upwards from 70's is pretty toasty. Not sura at what temp i saw it shutdown.

F or C?

Celcius.

 

I create a hole in my blade with a 120 mm fan blowing on the dual 10g chip. temps are now arround the 60 celcius. When doing nothing is around 52

I would say normal. My Intel NIC can get to 60+ under load and it's gigabit.

All the 10Gbit NIC chipsets I've seen run really hot - hence they generally have big heatsinks nailed on top.

 

My Intel X540's can easily reach 70 C if they aren't in direct, fast, airflow from fans.

Do the chips on the board have any heatsinks? If not depending on the size you may be able to try adding some heatsinks with adhesive thermal pads to help cool them down.

Every 10Gbit NIC card I've used run pretty hot under load. I just try to add as much airflow to them as possible. 

This helps. Thanks.

 

I just built an AMD Epyc, Supermicro H12-SSL Server.  I use the excellent Ultimate UNRAID Dashboard - Version 1.5 which shows my 10gb nic running ~68 Celsius all the time.  I don't push it hard (yet) so i'd image it will get warmer.

(I think) It has a heat sink on it (under the PCI-E cards) from Supermicro - https://www.supermicro.com/en/products/motherboard/H12SSL-ct.  So short of rigging up some sort of additional airflow (It's in a used CSE-846, i'm guessing it's "normal". 

 

 

Welcome thoughts/feedback/suggestions!

Keep in mind many (most?) server grade boards assume a high level of airflow that rack mount cases provide. Desktop cases are mostly designed around noise levels, so you very well may want to arrange some ducting or add a circulation fan so the factory heatsinks get a constant airflow.

Thanks.  I'm using a supermicro rack mount case, CSE-846 - https://www.supermicro.com/products/chassis/4U/846/SC846E1-R1200.cfm

It has the stock 5 fans in it. What further would you suggest?  

Thanks!

Check the motherboard's fan profile to make sure it's ramping up fan speed when needed.

I have 3 x540 and a noctua fan in line they run "hot" but how can I see the real temperature from unraid?

 

The max power consumption according to specs is 19 watts but any idea what is the normal consumption when running at low speeds or idle?

 

It's possible to tune up any parameter to improve the consumption?
