i5 2500k and CM 212+ are these temps okay?

post #1 of 33
Thread Starter 
I just built a pc from scratch last night for the first time and I'm worried that I may have messed up when applying the TIM. I used a three line method on my CM 212+ as demonstrated here.

I've run Prime95 for 3 hours on my NOT OC'd system to test the temps I get (I figured 3 hours was enough since I'm just testing for temps, not stability.)

System details:
Proc: i5-2500k NOT OC'd (yet)
Cooler: Cooler Master Hyper 212+ with extra fan for push/pull airflow
Cooler Fans: CM Blademaster (each doing 2000 RPM with 76.8 CFM)
Intake and Exhaust case fans: Rosewill RFA-80-K (each doing 1900 RPM for about 25 CFM)
My apartment temp (is this "ambient" temp?) was about 18C (65F) throughout the test.

Results:
Idle core maxes: 35/34/34/34
3 Hours Prime95 with fans on full (see fan details): 49/50/49/49
Voltage throughout test: 1.2v
The Prime95 temps stayed at that level for the last 2 hours.

I feel like this should be lower seeing as I have the p/p on the 212+ and am running the cooler fans at full speed.
Could I get your guys' thoughts?

That's fine, you want to aim for hitting around 70c - 75c on prime95, personally I wouldn't be comfortable going higher than that.

Yeah those seem perfectly normal, well your idle temps might be a tad bit higher than normal, but your load temps are good, and those are what really matter anyways. OC time! Like the compuman said, load temps should peak in the lower 70's before you start backing off when OC'ing.

Once it's overclocked you mean?
Right now I'm just running at the stock speed of 3.4ghz, but I'd like to try for 4.5ghz 1.325v and not go above 68c. Do you think I'll be able to do that when I'm getting these temps at just 3.4ghz?

I'm very new to overclocking, so I don't know how temperatures scale with clock increases.

Load is about 50C stock...seems high to me personally. I'd be shooting for 46C. Remount?

There are a lot of factors that will contribute to the temp increase as you OC. Each chips is different, each case flow is different, each heatsink is different. You may have a chip that doesn't require a lot of vcore to up the multiplier, so your temps won't go up as much as someone who needs more voltage.

I think your stock temps are perfectly fine. I would just take your time and slowly add voltage and increase the multiplier until you get the speed your want or hit the temp level you are comfortable with for your setup.

Something to keep in mind, unless you are going to be doing something that puts your system at full load for extended periods of time (folding, etc) rarely will your system reach the temps it does during stress testing. Using programs like Prime95, OCCT, or Intel Burn Test really put the system to wall to see what happens, but doesn't necessarily simulate day to day activity. Just something to keep in mind.

Good luck and post back your results.

As long as you keep your temperatures below 73C as what Intel stated, you're good. 68C after overclock is still fine, you still have 5C of room to spare.

Hey guys, thanks for all the responses.
I went ahead and started overclocking, but I'm having some problems. CoreTemp as well as the EasyTune6 util that came with my mobo are detecting my CPU clock as only 3.3GHz.
I've set everything up to be 4.5GHz by following the directions here.

Does anyone know what might be causing this? Could these readings be wrong?
My mobo is the GA-P67A-UD4-B3.

Have you disabled Intel speedstep/EIST and C1E. I would also download Prime95 and run it on 4 cores, you should see it jump up. Also, check CPU-Z

For the life of me I can not get speedstep to disable. I've disabled both EIST and C1E in my mobo and set the Min and Max procs to 100% in Windows 7's Power Options.

When windows firsts starts up, and if I'm trying to open a ton of programs, the clock will jump up to 4.5GHz, but once everything has finished booting and I start running Prime95 the clock sticks at 3.41GHz and won't go any higher!
It's kinda frustrating.
Any ideas?

Also, I downloaded CPU-Z and am using it to monitor now.
