Cpu highest temperature on intel i4770

Try another monitoring tool . Real Temp for instance . At 100-105 degree Celsius the computer will shut down . max Tj for 4770 = 77.72 C and max Tcase= 72.72C . Tj is core temperature

Turn off any overclocking - from BIOS,app . Open the case and check if the fans are spinning . Increase the fan speed , add extra fan . Change the thermal paste .

Respectfully, you appear to be somewhat misinformed. If you're not sure, then don't post. When any Forum Member posts incorrect information, it becomes misinformation, which is difficult to correct after it spreads throughout the community. Remember than others in the background read the threads without offering any comments, and may take away wrong information.

Unfortunately, Intel's Thermal Specification are written by engineers and edited by lawyers, so to most folks, they're about as clear as mud. The topic of processor temperatures is already confusing enough, so please research if you're not sure.

There's a wealth of information in the Stickies, and Tom's does ask that you read them before you post.

Intel Temperature Guide - http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html


Please carefully read the entire Guide.


From the Guide:

" ... Section 6 - Throttle Temperature

Also called "Tj Max" (Tjuction Max), this is the Thermal Specification that defines the Core temperature at which the processor will Throttle (reduce clock speed) to protect against thermal damage. Although Intel's Core i processors are capable of operating above 90C, we also know that excessive heat kills electronics. Sustained Core temperature greater than 80C is too hot for stability or processor longevity.


Section 7 - Relative Temperatures

The relationships between Ambient temperature, CPU temperatures, Core temperatures and Throttle temperatures are shown below for several popular Quad Core processors. All values are based on Intel documentation. ...

-> Core i

1st Generation 45 Nanometer: i7 920 D0 (TDP 130W / Idle 12W)

Standard Ambient = 22C
Tcase (CPU temp) = 67C
CPU / Core offset + 5C
Tjunction (Core temp) = 72C
Tj Max (Throttle temp) = 100C

2nd Generation 32 Nanometer: 2500K / 2600K (TDP 95W / Idle 8W)

Standard Ambient = 22C
Tcase (CPU temp) = 72C
CPU / Core offset + 5C
Tjunction (Core temp) = 77C
Tj Max (Throttle temp) = 98C

3rd Generation 22 Nanometer: 3570K / 3770K (TDP 77W / Idle 4W)

Standard Ambient = 22C
Tcase (CPU temp) = 67C
CPU / Core offset + 5C
Tjunction (Core temp) = 72C
Tj Max (Throttle temp) = 105C

4th Generation 22 Nanometer: 4670K / 4770K (TDP 84W / Idle 2W) <-----
4th Generation 22 Nanometer: 4690K (TDP 88W / Idle 2W)

Standard Ambient = 22C
Tcase (CPU temp) = 72C
CPU / Core offset + 5C
Tjunction (Core temp) = 77C
Tj Max (Throttle temp) = 100C

4th Generation 22 Nanometer: 4790K (TDP 88W / Idle 2W)

Standard Ambient = 22C
Tcase (CPU temp) = 74C
CPU / Core offset + 5C
Tjunction (Core temp) = 79C
Tj Max (Throttle temp) = 100C

The Core temperatures above show that mid 70's are safe. At Standard Ambient 22C, here's the typical operating range:

80C Hot
70C Warm (Heavy Load)
60C Norm
50C Norm (Medium Load)
40C Norm
30C Cool (Idle) ... "


I hope this helps to clear up the confusion,

Sorry but i cant accept your accusations ! First , i checked
http://ark.intel.com/products/75122/
it says T case = 72.72 degree Celsius . The second i made is to add 5 degree Celsius 72.72 +5 = 77.72 . Third - rounded to the lesser number for safety and got 77 Degree Celsius .

i can assure you that my i3 2350M throttles just at that TJ Temp which is 85 Degree Celsius . i ve got this laptop , i know what happen . i underline double : mine throttles just at Tj !!! Neither 100 nor 105 .

The fault is of Intel , publishing only T case for desktop computers and no number for Tj and throttle temperature .

All my information have been collected with the necessary care and attention .

Answer me something , what happen at Tj ? And what at Throttle temperature ?

We dont need strict words , we need knowledge how to protect our processors . i again stress , my i3 2350M throttles at 85 degree Celsius and it is horrible !!! it s alive thankful to my experience - decreasing the max CPU state at 50-85% in Windows power plan .

Please , answer what will happen if the i7 4770 hit 78 degree Celsius ? Why do we need misleading/unnecessary information ? Just tell Intell - Write it as it must be !

i LOVE Intel . i know ther advantage over AMD . But they should clarify some topics and publish some information .

Regards

Edit :
for me at 78 it will lower its frequency to protect the CPU but at 100 -105 will just shut down .

Edit 2 : My laptop has only one disadvantage - poor cooling and only one cooling fan . This is the reason why my laptop tends to overheat . Here the fault is of the laptop manufacturer , not Intel .

rockie_,

I stand corrected, sir. Occasionally I make a blunder, and I apologize that this time it was on your behalf. Moderators do make mistakes. I should not write when I'm too tired! I looked at your post several times and saw 72.72 instead of 77.72. Clearly, I can't read, either! Very sorry for my mistake. Obviously, you are indeed well informed.

There are two Thermal Specifications for your i3 2350M; 85C for the PGA variant, and 100C for the BGA variant. CPU-Z may show this information. Yours must be the PGA variant, which explains it's throttle behavior.

Once again, I sincerely apologize for my mistake.

Thanks !
