i5-2500k Temps??

Hi guys,

I'm pretty new to overclocking. I recently bought a new system built on a i5-2500k, MSI P67A-GD65. I just received my new cooler I ordered, a Corsair A70. So I figured, better get into overclocking the baby!!

Everything is working fine right now. The only question I have is about the temperature of my CPU. I've tried searching the net to find out what is the comfortable temperature margin for this CPU and people seem to have different ideas on that. I'm currently running it at 4.5ghz with a VCore of 1.28V. The max temp I got after 2h of Prime95 is 67C (with Real Temp GT and SpeedFan). Now, I want this overclock to be my everyday type of thing, something I can leave it at pretty much forever. For that reason, I don't wnat to stress my CPU temp to much, thus reducing it life.

For your info, I based my overclock on this guide: http://www.bit-tech.net/hardware/cpus/2011/01/07/how-to-overclock-the-intel-core-i5-2500k/1

As I said, I'm new to this so I had to base myself on something!

Thanks for your help
Jeff
 
Below 80 is acceptable during stress testing. Normal every day tasks will never load the CPU like a stress test, so id say your temps are OK.
 
It does seem high for a watercooling solution.

for example I am at 1.35vcore@4.8 ghz and my temps cap at ~62degrees

Edit: But as said above anything under 70 is fine really.
 
The comfortable temperature margin is 100C. Anything below that is fine.

This. Speedstep will keep clocks low when idle, and it will only ramp up for heavy processing. (video encoding, etc). So if you're just browsing around and playing occasional games? You're fine.
 
Ok. I'll try putting the little cables to turn down the fans a bit from 2000rpm to 1600rpm to see what I get from that. I find it a shame that the fans that come with it aren't PWM and are pretty loud for nothing.

Thanks for you help.
 
yeah i don't go over 60 degrees at 4.5ghz (1.24) with a Asetek 570LX and barely touch 70 at 5.1. Really impressed with the unit so far. Now just to get 5.1 stable :), also using the same MSI board liking it so far really quite stable.

Also one thing to keep in mind is that temps will vary a lot between different processors, different voltages, and different ambient conditions. What people consider "full load" isn't always the same. Prime 95 varies what type of data is is tested every 15 minutes, and some of the tests that come later in the test can make a CPU hotter than the early ones. Other people will sometimes run a specific Prime 95 test and get a "full load" test from that, so its always hard to compare.

Try this to really see how the temps are...

Google "intel burn test" and get the 2.51 version (or newer). That is the first version with full Sandy Bridge support, so you want that one. Extract the files somewhere, open the Intel Burn Test (IBT) .EXE, set the "Stress level" drop down to "Very High", change the "Times to run" to 25, then click Start. Post back here with the temps, it doesn't take too long to run. If you start to see some scary temps with that, you may have a problem. If that checks out mostly OK, don't worry about trying to fix something that isn't broken.

Side note: For people with a 2600K, change "Threads" to 8 before you click "Start."
 
Your getting about the same temps as me. I've never gotten over 72C with my A70 when I tried 4.6GHz, 68C at 4.4GHz, and I replaced the Corsair fans with Yate Loons. Unfortunately I had to give it too much voltage to get it stable so I backed off to 4.4GHz
 
So running the Intel Burn Test, on High not Very High since I only had about 3gb of available memory (4gb system) I got a max temp of 62C. Not that my room temp is about 4C less than when I did my test yesterday so I can pretty much say that the results are the same or at least within the margin of error. For your info, I do my Prime95 tests running 4 threads and in small FFT mode for maximum cpu stress.

Got to say that my case probably helps as my cooler gets all the fresh air it can possibly ask for in the HAF 932.
 
that actually pretty good. Im currently running my 2600k at 4.8 with 1.375v and I get around 38c on idle and 78c load, but never get to 80c. I might try the intel burn test tonight and see what I get.
 
linpac gets my 4.5ghz@1.375 2500k up to 90c.. yikes! i'm too scared to let it keep running.
 
So I finally had the time to use the little cables I talked about (don't know how you call them!) So with the fans ramped down to 1600rpm, the temps didn't change a bit. I still get the 30C average on idle and 61C at full load. I guess I'll leave those in as they make the fans way quieter.

Thanks guys.
 
67 degrees is pretty good for that sort of overclock. The max working temp is 100, so you have plenty of room before frying :)
