the cpu is hitting the 85c! is that okay?

erm, this is my first time having a gaming laptop, what I've learned from desktop that 85c for the cpu is not safe, these are "loading" temps for the cpu btw, and the fan speed is %100, checked the heatsink and made sure no dust remaining, and room temp is 22c! is there a known issue like bios or something?

repasting would void the waranty?

thanks

 

Mine hitting 94*C in benchmarks so 85*C isn't a big problem.

 

Not abnormal, though a good repaste would lower it a bit.

 

by"loading", I was implying specifically to 5 hours of gaming! not a short bechmarks!

which makes me wonder if MSI will void the warranty if I repaste the CPU

 

In a desktop PC, 85C isn't safe for the processor. Take the Intel i5-2500K, it's rated up to 72.6C.

But, laptop processors have a much higher max temp. Most Sandy Bridge processors are rated up to 100C. So 85C, for a mobile processor, isn't too high.

The GTX 260M in my Asus G51 would hit the high 90C's before I re-pasted. After the re-paste it only went up to 85.

Intel® Core? i5-2430M Processor (3M Cache, 2.40 GHz))

Intel® Core? i5-2500K Processor (6M Cache, 3.30 GHz))

 

Yeah, the mobile department requires a much higher temperature to enter dangerous territory.

My i5 hits around 85*C if it doesn't have the cooling pad I use. This is normal for that chip. The maximum rated safe temperature is 105*C for these CPUs, 85*C is the normal area. If you can keep it around 70-80*C by any means necessary, repasting would be nice, then I suggest you do so.

 

There are some errors here in where the temperature is measured.

72.6C is Tcase which is the temp measured at the center of the chip casing.
(most programs measure core temp which 15-20 degrees C hotter)

Tjmax is the temperature at which the chip will throttle itself.
(intel doesn't publish it, but its around 100 degrees C)

While I wouldn't say 85C is "safe" for a desktop processor, its not quite as bad as you think provided its the CORE temp.


Honestly, heat in laptops is a much bigger deal due to the spacing and better cooling that desktops have in comparison. 85C is borderline, but not horrid. 90-99 is running hot. 100C+ is "you need to turn it off" time.

 

Overnight Prime95. That's what I called benchmark... not a 3Dmark round.

 

85C is perfectly safe, even for 24/7 long term use.

 

That just seems evil to me. How can a few hours be insufficient?

 

Yeah it's evil but I wanted to know how my copper mod works. The main goal was to keep the GPU temp lower than before, and for the test I applied the max. stable OC on the cpu. It hits 94*C but no more on the cpu in a 6 hours stresstest. But not just the cooling was at its limit but the case itself. (MSI OC topic)

By the way 85 isn't too hot.

 

85C is a bit too much for the 2630QM.

My 2860QM stays around the 75C mark on full load.

Like others have said: a good re-paste will lower the temps. 85 is bearable though, getting in the 90s would required immediate attention.

 

my motto Cooler is better

heat kills electronics, and higer the temps = less life.

repaste, and see how it looks

nothing wrong with using a cooling pad as well.

last fans should be removed from the laptop and cleaned from time to time, blowing air through the vents does not really do a good job cleaning the fans.

 

I really appreciate anyone who replied and helped but again no one answered the qestion about repasing and the warranty and I hope fo someone to answer this

you said it mine "peaked" at 85c, but usually around 75c

 

You can repaste without loosing warranty. Warranty stickers are only transport stickers. But be carefull - when something will be dameged during operation - you loose warranty.

 

Just had this notebook a couple of weeks, and seeing this thread, i thought i would run wprime and use hwmonitor to check the temps.

And i am very happy after 10 mins with all cores at 100%, both cores are at max of 65c and i have virtually no fan noise, I will have to to run the integrated gpu at the same time and see how hot it gets then.

Your notebook is not comparable to a high-end gaming machine. No dedicated gpu and your processor is not an i7.

 

By breaking the "void if removed" warranty sticker, you're taking a risk.

TECHNICALLY, they can only claim you voided the warranty if the modification CAUSED the failure [ex: you went to re-paste CPU, botched it, and destroyed the CPU in the process]. If you re-paste the CPU and a few months down the line the HDD fails due to defect, etc. . your warranty will cover it..

That doesn't mean they won't attempt to challenge it should you require warranty service after re-pasting, but if access to the CPU/GPU on the 780 is as simple as on the 683s, I wouldn't even worry about it if you're even halfway comfortable doing the work in the first place.

 

doesn't this prove that I have the laptop? LOL, damned keystrokes issue!

anyway thanks alot! and I may begin the process soon as I get the IC Diamond in my hands wouldn't risk it with the current AS5 since I heard it was conductive and may cause trouble! or better yet, short out the motherboard.....somehow! :\
