How long can my CPU last when gaming in 80c+?

My CPU produces a lot of heat while gaming. Usually in the 80c-85c. Worst of all the damn cooler fan keeps spinning so damn loud when this happens. I tried every possible fixes with dust cleaning to new thermal paste etc. Even got a friend whose a expert in computer to do these things. I'm convinced it's my liquid cooler's fault. But I don't care if it's going to break the CPU anymore but still curious on how long do you think the CPU's lifespam is going to be at this rate? The CPU is i7 5820k 6 cores.

Thanks in advance.

Kinda depends on the liquid cooler. The smaller 120mm rads are good for 140-200ish watts, the 140mm @ 180-260ish, the 240mm @ 240-340ish, the 280mm @ 300-400ish. You have a 140w cpu, push it with all 6 cores at stock voltages and you'll be hitting right around that 140w mark. Understanding that TDP is @ 20-30% lower than possible heat output, if the stock voltages/stepping on that particular cpu are running high, you could be seeing heat output closer to 180w under something like p95 or Aida64. That's going to stress a 120mm cooler and give you temps in the 80's easily. Add in upwards of 100w to a good OC, and you'll be needing a minimum of a 240mm cooler, with a 280mm cooler advised.

At 4.9GHz (upwards of 200w) on my i7-3770K (77w)...

As long as your voltages are stock or near stock you should be fine.

Try undervolting if you haven't.

 


More than long enough for you to save up for a better CPU cooler. It could last another ten years. How long will my CPU overclocked to 5GHz from 3.9GHz last for? Another one of those prediction questions that really doesn't have an answer. It is hot by Intel's standards but not hot enough to suggest it will self-destruct in 6 months or less.

At 4.9GHz (upwards of 200w) on my i7-3770K (77w) with a 280mm kraken x61 @1.32v I see 74°max after ½ hr test of p95 26.6 @ 55°C gaming hard. (fans don't break @ 1000rpm) Even a decent OC on a 140w with a 280mm aio, shouldn't be much more, if any, than that. My only conclusion is the liquid cooler you have either isn't performing as it should for some reason, or more likely is not large enough to do the job adequately. A Corsair H60 has basically the same performance as a budget CM hyper212 evo, for instance, which is wholly inadequate for your cpu under anything more than idle loads.
