post your voltages, bcklock etc for some help

Also it would be helpful if you edit your system so you dont have to post it every time.

Welcome to ocn

Put your system specs here :http://www.overclock.net/specs.php?do=addsystem

 

[KaRLiToS]

You have not indicated any voltage, but honestly, the temperature seems high, especially with a Feser 360 with push/pull fans, have you put good thermal paste, is the block well seated? What are your room ambient?

 

[jamborhgini313]

wow even with HT off and its 77 degrees? reseat and reapply thermal paste!

 

[Haze_hellivo]

Temps seem high but more info could help.

Just updated my system specification. I re-seated the block few times. Room ambient is 24-26C.

Yes, HT Off. Reseated and reapplied the block few times.

Just updated my system specification. Please refer to that and let me know if you need any additional info. Thank you.

Bad air flow on the Radiator?? High Ambient? Bad chip maybe!

I doubt on the cooling system. Should be either CPU block or RAD. I saw some using up to 1.425 V for CPU Voltage but their temp under full load still below 70 C with HT ON and XChanger 360 RAD.

Is my voltages all okay?

Before this I was using Swiftech MCR220 RAD. OC'ed 3.8GHZ HT ON @ 1.38V, temperature around 74-76C. Is it something wrong with my CPU block?

What's your opinion about Corsair H100 for i7 920?

I'm getting insane with custom water cooling, not works out for me. Spend quite much and ended up with disappointing results.

 

[KaRLiToS]

Maybe you should check your CPU block , open it, or check the pump and the flow maybe, fans are often important on radiator.

Maybe its about your room temperature, is it hot where you live?

Malaysia is pretty hot now a days, but my room is air-conditioned. Usually I'll set the temperature around 25C.

I'm using Arctic F12 fan. RAD I mount at top of HAF-X, the only place can fit without any MOD.

And your opinion about HAF-X for i7 920? Thinking of sell off my custom water cooling setup and getting myself Corsair H100.

 

[KaRLiToS]

Dont do it, a Feser X-Changer 360 is much better than a corsair H100

Do you have good intake in your case, I guess your Rad is internally at the top of the case as an exhaust?? Can you post a pic of your Case.

3.8 Ghz with 1.38V is quite high, you should be around 1.2v and 1.3v on that OC, your voltage seems high a little.

I have two fans pulling in air, 1 x 200mm at side and another 120mm at front.
Yeah, my RAD is inside the case.

3.8 with HT ON at 1.38V quite high is it? My CPU couldn't stand Prime95 for more than 2 hours if voltage is lower than that.

How about my current voltage for 4.2GHz HT OFF? Is it high as well? Could you go through my BIOS setting and give some advice or suggestion?

My CPU is kind voltage hungry. D0 revision but acquiring voltage more than C0/C1.

 

[KaRLiToS]

I have a feser 360 also for my cpu and I'm at 4.3 Ghz HT On 1.33125v and my temperature in Prime 95 are around 65-68'C and with Linx they are at 70-75'C

Could you give me some setting suggestion based on my BIOS setting in page 1of this thread? Give up after been trying for so long to getting lower temp and voltage:sadsmiley

Since you also using R3E, you might have experience with the board directly.

You have 25% That my settings will work for you, i7 920 and the 930 are not very different, almost identical. But it also depends on your memory. What is your Corsair memory???
