hey guys , i've got a new pc with intel xeon e5-1650 0 3.2ghz ,and literally while doing nothing the utilization is like 2% but the clock speed is 3.5ghz which make the temp goes up to 65-70 and the fans is too noisy , i tried setting the power plan to balanced and nothing changed
 
How many watts does it consume? If less than 15 then it's nothing you can do but fix your cooling solution because obviously it's suboptimal.

do u know why i dont have speed shift option enabled?? i dont have it in throttle stop, and i don't have FIVR menu

I never used this software, no clue.

My way is oldschool BIOS settings calibration and then further this:

It looks a bit high, but I am comparing to my 3770K. Is this a new windows install? If so give it a few hours to straighten itself out. If not.. well its not terrible for a server part.

new windows yes , just installed yesterday
 
its a old chip its gonna go into boost more because its a slower cpu
 
ok , but while playing any game the fans goes crazy noisy , and the temp is not too high
You might be able to change the fan curve in the bios.
 
tcase max on that cpu is 65c
 
The fans are going to 100% because it's hit its maximum rated temperature upgrade the cooler
I assume this is some kind of server chassie servers are not built with quiet operation in mind

is it dangerous for the fans to run at 100%??

and is there any possible way to enable speedshift in throttle stop
 
set powerplan to something other than performance
 
Ya need a better cooler than stock. Ran Hyper 212's on 2680v2's in the past with no issues.
 
ok but why is it running at full clock speed when idle
It's a single core clocking up for background tasks. This is normal. What isn't normal is your awful cooling situation.
 
all the cores all clocking up bro
Where are you reading this? Task manager does not show per core clocks, only hwinfo or similar.
 
What type of motherboard you on? Server or X79? Not sure about server boards, but you'll need to enable C states in bios, and preferably use offset vcore so it will downvolt as well.
I've run the 1650, 1660 and 1680 cpus, all of them would downclock and downvolt for me. Also make sure speedstep is enabled in bios....
 
If there is a hardware p-state option, you can turn it off (might be labelled as speedshift), hardware p-states will ramp up clocks quite agressively, bear in mind the 2% usage is from the polling period, it doesnt mean the cpu didnt spike higher then that for a short duration.

The downside of software p-states is not so good interactive performance, this can be offset by raising the min clock speeds, as efficiency remains good on any clock below turbo, so even max non turbo clocks will be power efficient and run cool.

Your CPU was made before FIVR and speed shift were introduced into later CPU's so you don't have those options

EIST should be enabled in BIOS to run at lower clocks and table passed from BIOS to Windows.

FWIW I prefer running full speed (no EIST) and let the C-States do the power saving. C-State C1 aka HALT stops the core clock so 0 MHz. Higher C-States bring more power savings.

Catch 22, to monitor cores they need to be woken up, operate in C-State C0 so that the software can read their registers before leaving them to return to C1 or higher. However this should have minimal effect on power consumption due to short time. Some software read the clock at that instant, others the average active clock over the period.

IIRC throttlestop can monitor C-States? Better to see what's going on with power saving.

Is it a an ES CPU?

Check temps / throttling at full load.
