cpu at 75C when gaming.

is that temp safe for stock cooler? (I have been researching for an aftermarket cooler for 2 days and still haven't decide which one to go with. so spare me if u gonna post sth like WTF ur rig with STOCK COOLER TROLOLOLOLOLOLOL!!!!!)
 
If your PC doesn't turn itself off, it's "safe". But getting a good aftermarked cooler will be "safer". The cooler a CPU runs, the better.
But your signature says you have a Corsair H100 already. Is that the PC you're talking about?

Edit: for (a bad) comparison, my AMD Phenom II 960t runs at 40 degrees max, under 100% load. AMD CPU's generally run at and tolerate lower temperatures, but that is still quite good. Seeing how your signature setup must have cost sh!tloads of money, you should have no problem buying a good aftermarket CPU cooler if you need one. Look at the most recognized brands (Noctua, Zalman, Cooler Master etc.) and choose the prettiest - the performance differences are negligable.

It is safe. It will degrade faster than a pc running cooler but negligible with regards to useful lifespan.
 
If you are gaming at 75c, yes that's ok BUT when you stress test, I bet that CPU is peaking 90c, which is really not so much safe.
 
That's pretty high for gaming, but it's not unsafe. My temps typically are in the mid to low 50s when gaming for an extended period of time (though will peak at mid 60s under a stress test). It should be fine for use in everyday tasks and gaming...probably would only become too hot if you were stress testing, or possibly if doing a large video encode, though on my machine an HD video encode usually peaks about 5C above where it is for gaming (58-60C). When I was running on the stock cooler, I'd be in the mid to upper 60s for gaming and upper 70s to 80C for stress testing, so your rig isn't running too much hotter than that.

It's not gonna fry or kill itself quickly at those temps, but anything that really taxes your processor will probably push it into a dangerous zone.

Also the hotter your processor runs, the quicker it degrades and more power it consumes.
 
You want an answer we cannot give. Is driving on the expressway at 70 MPH safe? What about 72MPH? 79MPH? 80.3344444 MPH?

Use specific terms other than "safe". There are four temperatures to be concerned about. The temperature that makes it unstable (may just introduce errors not total crashing), the temperature that causes permanent damage immediately, the temperature range that causes faster and faster degradation of the CPU-as-whole-package through thermal cycling, and the temperature your motherboard power subcircuit is reaching due to either the insufficient airflow the CPU heatsink pushes past it, or the high power level from enough overclocking to get a CPU that hot with a decent heatsink on it.

The generic answer is your CPU is hotter than it should be, just as we can't nail down a specific MPH to drive unsafe, the higher the temperature it is, the less safe it is.

Forget about gaming. The system is not configured properly if the CPU cannot run at full load during a stress test and stay under 75C indefinitely including the hottest day (highest ambient room temperature) of the year, let alone the lesser load of gaming. If you'd prefer an improper /risky config because gaming isn't really a crucial activity on a PC, that's a choice some people make too. So long as it works for you.

If you have a corsair H100 already, and you are hitting 75 degree gaming, you did something very wrong.

Oh, and the 3820 doesn't come with a stock cooler.

Maybe he thought the shiny flat thing bonded to the CPU was the stock heat sink? 🙂
 
There is NO way i'd be running my cpu at 75-80C under load. That is too high for everyday use. Yes it can handle it, but that is hot.

If you can afford the X79 motherboard and that cpu, there is no reason to not use a $25 CM Hyper 212+ on it. 🙂
 
For a Core i7 under great load, late 70s is fine. 80s is okay but not recommended at all. But unless you play several hours a day and intend to use that CPU daily for 2-3+ years, there isn't much of a risk.

Ideal is as low as possible. Preferably 60s or so under full load or lower, however, that isn't absolutely essential.

Many people with high overclocks get in 70s, and frankly if it is only occasional then even 80s would be fine.

But don't touch 90, better to get better cooling before that.

But 75 is fine, although a good cooler will bring it to about 50C at full load at stock speeds and sub 75C under overclocked settings 🙂

Yes, but with any aftermarket cooler that too at stock, 50s is the max I would say you would get. or at most lower 60s in a hot country. now that isn't essential, but any good cooler would ensure that which would mean more margin for overclocking 🙂
