Can somebody help me please?
I bought recently this CPU with mobo brandnew, but i overclocked towards 2,8Ghz and not higher cause its getting very hot at idle.
My CPU cooler is Arctic freezer 13 placed horizontally(PSU on top of case with fan facing down)
Got 3 Antec 80MM fans and one 120MM scythe fan.
This is the setup of the fans, 2x 80MM on backpanel blowing cold air in. 1x 80MM on side panel blowing cold air in. 1x 120MM on front sucking hot air out and room temperature is 20-22c.
It has a new thermal paste which was premounted on the CPU cooler i bought.
The brand of the case i dont know(guess brandless). next month i gonna buy a zalman z11 plus.
Is there something wrong in the cooling system i use(wrong placed?) or what you guys think.
I've checked other threads here but none helped me.
And is the PC case i gonna buy good?

Definitely thats too much , that cpu in my case when I had it was about 35-40 in idle with a scythe yasya and oc´ed to 4.0GHz and 65-70 on prime .

You made sure thermal paste is right applied , and that the heatsink is doind the right pressure on the cpu ¿? . Also try other monitoring programas like openhardware monitor , hwmonitor , speedfan . Btw take a look to the temps in the bios .

well i7-920 is a lga1366 socket cpu, and it has similar power characteristics with lga2011, which results typically higher power consumption and higher temperatures than casual lga1156/1155/1150 socket cpus.
so it is normal to see higher temps, however your temps are actually high...

but I believe you cooler setup is kind of wrong from your explanations. here is a picture with Zalman11 Plus case to give you ideas. (btw it is a really great case, Im using one as well)

the air flow should be like; from the front to the back. front cooler should be intake, cpu cooler should be positioned to draw air from front and pushes it to the back. and fan on the back should be exhaust.

case backplate <<<air<<<< back fan <<<air<<< cpu heatsink | cpu fan <<<air<<< front fan <<<air<<< case front panel

in my setup i have 2 fans positioned in the same direction, the front one is pushing, and the back one is pulling. it just creates more air pressure but doesnt change the way the air moves. still front to back.

you may also want to tighten the screws of your cooler as well or re-install it again totally, there may be a loose end and cooler cannot dissipate heat from your cpu.

you should try re-installing in any case and make sure it is tight enough usually it is the 1st encounter to check.

Sure i will, altho i thought i tighten them enough.
Was afraid if i tighten it too well it might brake the plastic mount of the cooler.
Atm i'm following this thread true school and checking the temperatures, even put the cpu speed to stock to see if it might help, and when im back ill switch fan sides to see if that has some results
