gasolin :
mabye 40 idle, low load 45-50, prime 95 26.6 about 73 degrees (mabye a bit higher after 5-10 min). I do have disabled power savings so i guess it's ok (ambient 21.5-23C) although i think low load temps around 45 and up to 5-6% cpu usage (for a few sec it can go as high as 10% but only for 1-2 sec) is just a bit to high
Guys,
The thread took a left turn back here.
King Kevain jumped in probably without thoroughly reading what's already been resolved, which got
4Ryan6 going.
gasolin,
We've already established that your load temperatures are not a problem at you present settings, especially since you've now given us your ambient temperature. The original problem was that you simply weren't using P95 version 26.6.
Concerning your idle temperatures, you've already included the answer within your last post ... which is that
you've disabled your power saving features.
Just for everyone's benefit, let me be clear about this;
the only relevant temperatures are steady-state 100% workload, ambient, and dead idle ... in that order ... and even these are subjective!
Anything between 100% and
dead idle represents apps or gaming, and can't be used to analyze thermal performance, but they're great for speculation, conjecture and debate.
Respectfully, since there are too many variables involved, we can not form meaningful comparisons or draw valid conclusions based on thermal data such as "
low load temps around 45 and up to 5-6% cpu usage (for a few sec it can go as high as 10% but only for 1-2 sec)".
From the Temp Guide:
Section 11 - Thermal Testing Basics
We all remember science class where one of the guiding principles for conducting a controlled experiment, is that it's critical to follow the same procedure every time. This eliminates variables so results will be consistent and repeatable.
If everyone tests their rigs using X stress software at Y Ambient temperatures with Z measuring utilities resulting in CPU or Package or Core temperatures, then it's impossible to compare apples to apples. This is why processor temperatures are so confusing.
Sections 12 and 13 will explain how to properly test your rig at load, and at idle using standardized methods. Follow the "Setup" in each Section to duplicate Intel's lab test conditions as closely as possible. This will produce valid Core temperature benchmarks which are consistent and repeatable.
Section 13 - Thermal Testing @ Idle
" ... Core temperature sensors are designed to be more accurate at high temperatures for Throttle protection, so
idle temperatures may not be accurate.
Remember that when you power up your rig from a cold start, all components are at Ambient, so temperatures can only go up. With conventional air or liquid cooling,
no temperatures can be less than or equal to Ambient.
If "Speedstep", also called Enhanced Intel Speedstep Technology (EIST), is disabled in BIOS, then depending on Vcore and clock speed, idle Power can be nearly 40 Watts, which will result in high idle temperatures, especially when combined with high Ambient temperature.
Setup:
In addition to using the previous Setup under Section 12, Speedstep and
all "C" States (C1E on earlier motherboards) needs to be enabled to achieve the lowest possible idle temperatures. Also, if Windows Power Options is not set correctly, then Speedstep will not work.
To check this, click on Control Panel, Power Options, then to the right of the selected plan, click on Change plan setting. Next click on Change advanced power settings, then drag the scroll bar down. Click on + next to Processor power management, then click on + next to Minimum processor state. This Setting must be 5%. If it's not, then correct it and click Apply.
Restart into BIOS and confirm that you've saved your settings to a Profile. Next, change all settings to stock (Default / Auto) including SpeedStep, all C States and Vcore, then save and exit. Reboot into Windows and
confirm that your rig is at dead idle; no programs running, and off line. No Folding or SETI or tray trash running in the background, and less than 2% CPU Usage under the "Performance" tab in Windows Task Manager.
Use CPU-Z to confirm that Core Voltage and Core Speed has decreased as follows:
-> Core 2
1st. Generation 65 Nanometer ... less than 1.250 Volts @ 1600 Mhz
2nd Generation 45 Nanometer ... less than 1.100 Volts @ 2000 Mhz
-> Core i
1st. Generation 45 Nanometer ... less than 1.000 Volts @ 1600 Mhz
2nd Generation 32 Nanometer ... less than 1.000 Volts @ 1600 MHz
3rd Generation 22 Nanometer ... less than 0.900 Volts @ 1600 MHz
4th Generation 22 Nanometer ... less than 0.800 Volts @ 800 MHz
Use Hardware Monitor to confirm that Power has decreased as follows:
-> Core i
2nd Generation 32 Nanometer ... less than 8 Watts
3rd Generation 22 Nanometer ... less than 4 Watts
4th Generation 22 Nanometer ... less than 2 Watts
Note: Power (watts) isn't measured on Core 2 processors and certain 1st Generation Core i variants, but for general reference, idle power for several popular CPU's is shown above under Section 7 - Relative Temperatures.
Test:
Allow your rig to "settle" for 10 minutes, then use your thermometer to measure Ambient. Use Real Temp to measure your Core temperatures, then correct your results to Standard Ambient.
Results:
Core i 2nd, 3rd and 4th Generation processors
should idle at less than 8C above Ambient. This means that at 22C Standard Ambient your Cores
should idle just under 30C. Certain Core 2 variants and Core i 1st Generation variants may idle several degrees higher.
The better your cooler and the lower your idle power, the lower your idle temperatures.
