Hetzner tech says CPU temperature of 100°C is "okay"
Recently I've been dabbling with video transcoding on my Hetzner EX41 server, when I noticed that the CPU would run at 100°C and severely throttle. I didn't keep it running for long, but I saw it go from 4.2 GHz down to 3.3 GHz, which is even lower than the base frequency of the CPU.
To their credit, after putting in a ticket Hetzner quickly replaced the fan which improved the situation. Now the CPU can maintain 3.8 to 3.9 GHz under load, but still it would be running at 100°C. According to the technician, a temperature of 100°C is ok, as long as it does not throttle to below base frequency. So there is nothing more they can do for me.
Now, I understand the CPU has thermal protection - so it will throttle to stay under 100°C. But surely it's not a good idea to be running it that hot long term? I don't think it will be very good for the lifespan of the machine. The capacitors on the motherboard are very sensitive to higher temperatures. And I'm losing out on performance...
The CPU is an Intel Core i7 7700.
What do you guys think?
Anyone else with an i7 6700/7700 (Hetzner) server that can share their experiences, what are your temperatures like under load?
