i5 2500K Temps way to high!

post #1 of 31
Thread Starter 
Hello,

I just built a Asus P8P67 Pro with an Intel i5 2500k and my CPU temp at idle is 40c. Under load it sky rockets up to 72C!!! eek.gif

So I bought a Hyper 212 heat sink, and I got the SAME TEMPS. mad.gif

Then I got my watercooling bracket I needed to use it on the 1155 socket and my temps are the SAME as well! mad.gifmad.gifmad.gif

And my 2core temp is always 8C higher than the others. confused.gif

So with sidestep on which runs the CPU at 1.6ghz @ .9 vcore, Im idling at 40C. If I turn it off and run the CPU at its base speed of 3.3ghz @ 1.2vcore, Im at 40C. If I run my CPU in turbo mode @ 4.2ghz @ 1.25 vcore, Im idling at 40C.

And no matter what, load temps hit 65-72C!!!

Do I have a bad CPU? OR do I need to exchange my MB?


Thanks!

PS: This is my 1st intel ever. Ive had nothing buy AMD and my AMD Quad core system which was in the same case Im using now (Antec 900) and with the same watercooling system (TDX block, D5 pump, twin 120rad) would idle at 27C and would never pass 48C under load.

The i7s do throw off a fair amount of heat. Realistically, 72C is not that ridiculously hot. As long as it is under 80C you are in safe range. However, with watercooling, it should be a little under that. You might want to try adding another 120 rad to the loop, or else switching to a triple rad. You could also try getting better fans for the rad or doing a push/pull config. BTW it is normal for different cores to run at different temps.

If your temps are exactly the same all of the time, it could also be a bad sensor.

On what? The CPU or MB? Whatever sensor it is seems to work, as I do see some variances from air to water. Meaning, with the water cooling, it takes much longer for it to hit peak load temps, but still. Where is the sensor? CPU or MB?

If you are seeing variance in temps between air and water, that means that the sensor is probably working and your cpu is just running hot. Try to increase the cooling capacity of your watercooling loop. That should help.

Do you have your CPU fan at 100%?

Its hit 78C once, but that was on the stock cooler. I realize they run hotter than an AMD, but my radiator isnt even warm to the touch. With my AMD rig the intel system just replaced, the radiator would feel pretty warm. I would hope a 2X 120 radiator would be enough considering Ive seen others mention that their i5 2500k was idling at 30C and hitting 55-60C max load temps on AIR.

Regardless of that, where is the sensor? on the CPU or MB? Im thinking of exchanging them to see.


Thanks!

What TIM did you use and did you give it enough time to cure before measuring temps?

What is your ambient temp?

I don't see how he is getting 70c on water, I run a higher OC and never get above 61c under 100% load. I would take the advice previously mention, add another loop.

Btw, what does your bios say? Have you checked it and compared to the idle temps you see in windows?
