i7 2600k @ 4Ghz, is this normal?!

post #1 of 7
Thread Starter 
Hi there guys, I've had this chip for a year now at stock clock and voltages, I live in Barcelona and in summertime it gets very hot, so about three days ago I decided to take a look at the temps while I was playing League of Legens and found out my CPU was getting up to 97ºC drool.gif (was running on the Intel's cooler).

So I decided to upgrade my case(?) to Thermaltake Urban S31 and Corsair H90 watercooling. After putting all together, the temps went down to 34ºC idle and 45-50 on League of Legends. It was ok for me considering it was 97ºC hours earlier.

I OC the 2600k to 4Ghz, and this is where I'm confused. to get to 4Ghz stable on IntelBurn Test I had to set Vcore to 1.235v, but it gets to 70ºC (the room is a little bit warm).
After some reading on this forums, I decided to put some LLC, my surprise? I set the Vcore on the bios to 1.200v and LLC to level 3 (Gigabyte GA-P67A-UD3-B3. bios rev F9) and while running IntelBurn Test, the vcore goes down to as low as 1.152v sad-smiley-002.gif also, it still hits 70ºC, Is this normal? here's a screenshot while running IntelBurn Test, I can get you all the info you need if you need more.

PS. Sorry for my bad English, I'm trying to get better.

Idle temps and vcore right now, same config.

Yep, every processor does this. It's called Vdroop and is used as a precaution to prevent the voltage from spiking too high. Those temps all look fine. The stock Intel heatsink is complete garbage so that drop in temp isn't surprising. I'd try to keep temps below 70 though. If your room is really hot, I wouldn't mess around with overclocking too much.

But 70C with a h90 and only 4GHz is definitely not normal

That's why I asked if this was normal, temp in my room right now is 29ºC and the CPU is idling @ 35ºC. I'm using 1.2vcore and it's dropping to 1.152 when running @ 4Ghz hitting the 70ºC mark.
Could it be because the H90 is mounted up in the PC case? also, It's mounted as an intake in the Urban S31, there's also 2 intakes front(closed by a door) and 1 rear exhaust.

As I mentioned in the the previous post, I can provide pics of the tower and how's the heatsink is mounted, bios or anything.

Again, sorry for my bad English.

LLC changes the vcore positively and negatively. To have the LLC set correctly you need your cpu vcore in windows to be as close to what you set in windows when the cpu is under load.

The 70C your seeing is probably when your system was running at 1.200v.

Check out my 2600k overclocking guide if you need more info on LLC and how to use it.

Yeah, your temps seem high for that overclock and voltage.
