Are laptop CPU temps of 75C under load for hours a day ok?

I have an Intel P7350 and under load it reaches 75C.

 

That's nothing out of the ordinary. Notebook CPU's are rated for very high temperatures. 75c is about average of what you would expect out of a notebook cpu under load. If it ever gets to the point where the system might take damage, the CPU will automatically downclock, and if it continues to rise in temperature beyond the max threshold, your system will simply shut down. But this won't occur until it's over 100c+, so you have nothing to worry about.

 

CPU threshold is 100C , read it from intel website..
but 75 is still ok..mine reach 80 sometimes

 

But isn't 75C quiet high? My laptop never reach a temperature over 70C.

 

Yes and Sager's have much better cooling than your average thin notebook that tries to jam a C2D in with a terrible cooling solution simply to keep the size/noise down, like most notebooks do.

However of course if this is out of the ordinary it won't hurt to remove the heatsink/fan and blow the dust out, then put it back in it's place with some arctic silver 5, or other decent thermal compound.

 

Intel CPUs have pretty good tolerances to temperature. 75C shouldn't be a problem.

 

my former acer laptop with a t7500 cpu reaches 90+ easy nothing to worry about

 

This is certainly alright, Notebook/laptops have high threshold. I don't know if you guys read and watch a Dell laptop that exploded because of battery fault.
I guess this is the major component that contributes much heat especially when charging.

Anyway, all those Dell model are found out to have defective batteries and were replaced immediately.

 

Isn't 75c on the higher side of the the scale though? My p8700 idles around 50c, and only hits about 65 under load.

Graphics cards run hotter than Intel's processors though, and heat kills electronics... so why are there such high tolerances with processors?

 

75C won't damage your CPU. Your laptop bios and or CPU itself will downclock its own multiplier if it reaches too high. My bios downclocks the CPU when it reaches just 76C (overprotective lol) won't do that until I take it way over 3ghz tho

 

76c overprotective! Try around 60c for Acer laptops

 

75c is a little on the high side considering P series CPUs only have a max TDP of 25W, it won't damage your CPU instantly, but in the long run keeping your CPU running at such high temp is definitely not healthy. My p8400 doesn't even exceed 45c under heavy load while gaming, thanks to the great cooling system and undervolting.

Try undervolting your CPU if u haven't done so, it surely will help lowering the temp a lot.

 

I was just worried cause here , it says:

CPU danger temperature is around 75-85C (check the CPU's tech specs)

 

Thats definitely a bit high for the P7350. my P8700 OC'd to 3.1GHz maxes 10C lower, and stabilizes 14C lower.

 

Thank all who share information, this result is the necessary information for me.

 

Let's just say heat will damage CPU's over time, but users will usually have updated their laptop before it even gets close to its end of life.

75C is hot, but not outside of spec so should be fine.

 

Asus laptops often reach into the 80s and 90s while gaming.

 

GPU yes, CPU no.

 

Oh wow, I just undervolted 0.1v (will be doing more tommorow) and it already dropped to 68C under load. I HIGHLY recommend this undervolting guide to anyone, it's really easy to do and does wonders.

 

75C sounds awesomely hot. Acer laptops usually max 70 at load, even for hours. im not too sure about the Intel chips being resilient tho.

 

mine will be at 80 to 85 for 4-5 hours at a time if i have a lot of video conversion or gaming to do. it isnt a problem.

 

While I wouldn't recommend it to just anyone (if you skim through a few random pages of the thread, you'll see that tons of people can't follow directions even when there's pictures), it really does work wonders. I dropped my maximum full load CPU temps from ~80C to ~60C, with ~55C being typical on a heavy load.

 

You can always use Cpugenie's undervolt wizard to do that too. I find manually testing individual voltages to be extremely tedious.

 

my t5800 undervolted maxes out at 63*C.

 

But there's a problem with CPUgenie... the voltages don't stick after you restart... is there any way to make them stay?
