I don't like: * Pentium G5420 has 54W TDP. That's a lot. It'll be noisy under load. I'd prefer something like Celeron G4932E with 27W. I don't need performance, I need quiet operation and ECC support. * iLO enablement kit is $100 and need physical delivery. No more $5 ebay key. That's a shame for home consumer. Also I was not able to find a price. Hoping for the best. Buying Gen8 for $300 with cheap iLO key was a gre…

That CPU is a great choice. The specs on paper won't tell you the whole story. I've got the Pentium G5400 and even though it's rated at 58W TDP its actual power consumption and heat output is on the low end. I don't have my notebook with me but I ran a small at home experiment with a kill-a-watt sort of device while monitoring temps. Found consumption to be around 21W in idle, 26W for light loads, between 35W and 42W…

Thanks, that was a very informative comment.

When you get melting/burning temperatures you are already screwed, and burning metal is far more dangerous, try turning some metal wool on fire.

Speaking from experience, it is much, much, much more feasible to reach the burning point of wood or the melting point of plastic in a datacenter than the melting point of the metals used in server construction. One of the jobs of the case is to contain a fire if it starts. A plastic case wouldn't do this, and a wood case would actively be hazardous.

Do you have a story? I've never experience more then 120°C in electronic equipment as it's usually the safety limit where it would shut itself off. Although in theory the silicon would still be fine at 300° where wood starts to burn.

Can you stick any hard drives you want in there, or do they have to be HP drives?

At least up until Gen8 you could use any drive; the bays came in standard dimensions and took my Western Digital drives without a problem. I don't see why that should have changed in the meantime.

Wasn't there something about fans blowing at 100% with non-HPE drives due to their firmware?

Two situations come to mind:

1) Several appliance machines were in a cabinet with water-cooling doors attached. The doors restrict the airflow from the front of the cabinet to the back to the point where there isn't sufficient airflow to cart away the heat from the CPUs. The engineer responsible for those particular systems played show-and-tell with the melted plastic pins that formerly held the motherboard in-place for a month after the machines crashed.

2) An 8-year old rackmount machine had a power supply fail spectacularly and light the entire server on fire. Fire suppression was triggered in response. Several other adjacent machines were damaged but the fire stayed relatively contained to the one cabinet.

I'm happy to show you quite a few servers which run almost at their TDP for 7/24/365. Yes, it's not very applicable to home scenarios but spike loads create a lot of noise at home when a CPU has high TDP.

Surely it's clear we're talking about home and small business servers?

For sure but what about home servers which do transcoding for example?

They will run at their TDP for some time and, create considerable noise and heat.
