CPU lifetime when under constant heavy load and high temperature

VVahe — Fri, 11 Jul 2014 01:22:28 GMT

Hello everyone,

I have recently started to donate my CPU power to the SETI@Home and rosetta@home projects. This means that the computer I have on 24/7 is nowadays under constant, full CPU load.

The temperatures regularly reach 100 degrees Celsius and peak at 105 degrees Celsius, which is intended as far as I know (105 being the hard limit on these CPUs). My question would be if this kind of usage has relevant implications on my CPU lifespan, or whether a CPU death through this kind of use would be covered by warranty. I understand that it is impossible to give an exact answer, but I would be grateful for some insight on this issue. I have read comments from experienced overclockers that if you overclock a cpu considerably, it will shorten its lifespan, but the figures are something along the lines of "from 15 years to 10 years of a fully functional CPU". 10 years would be more than enough for me.

I can decide not to keep running the program if my CPU lifespan is shortened considerably, but I would prefer to keep donating my CPU power if it has no relevant harmful effects on my hardware. I'll be happy to post more information, should you need it. Below are my system specs.

Thank you in advance for the answers and comments.

Kind regards,

Schwerbelastung

Thanks for joining the processor community.

I thank you in advanced for the idea to share your processor power for such project.

Indeed lifespan of the processor will vary if your processor will constantly run 24/7. Intel is going to cover the processor if it gets defective within 3 years of warranty.

If you need information about how long will your processor run, please let me know, so, I can send you a private message.

Allan.

Hey Allan,

thanks for the speedy reply!

I understand that the lifespan of the processor will be affected by heavy loads and especially high temperatures. It's good to know that it is covered for at least three years. Also, please do send me information about my processor's expected lifespan (according to the details in the OP) via PM when you can. I'd be very interested to learn about this.

Looking forward to hearing from you. Thanks again.

Regards,

Sure, I will send you the information as soon as I get details for your processor.

I Have this issue too.

I need a datasheet or any papaer that show life span of cpu in 100% load in 24/7.

I Need it for my resaerch.

This information is not publicly available, if you are requesting Mean Time Between Failure documentation, please provide your processor model.

Could you PM me the MTBF of i7 4930k at 100% load?

Hi Allan_J,

I'm also curious about the life expectancy of an i5 processor, since we're planning to embed the processor into biometric product, but would like to offer a 5 year extended warranty option to some of our customers.

I've read that over-clocking and poor cooling will obviously shorten the life-expectancy, but assuming the product design meets Intel's design requirements, I'm curious to understand what the average life-expectancy of the CPU would be? I've read 5-10 years on lots of forums but nothing official. Do you have any data that you could possibly share please?

Kind Regards,

Neil25

I Have this issue too.

I need a document that can illustrate the expected lifespan or Mean Time Between Failures (MTBF) of xeon d-1747nte at a core temperature of 100 / 95 / 90 degrees Celsius .
