CPU Heating Issue?

Last response: in CPUs

I have a Intel Core i5 2500K. My temps on idle are around 30C and when I am gaming it reaches 37-40C. Is this bad for my CPU? I am using the stock heat sink right now. Can overheating of the CPU cause the computer to cycle on and off every 3 seconds?

Those temps are perfectly normal for your cpu.
Unless your hitting 70C when gaming you have absolutely nothing to be concerned about.

Those temps are very good. If you have a 2500K, why don't you OC?

The highest I have seen when gaming is 40C. So this would not cause my PC to turn off on and on.

No it wouldn't. There's no reason for your PC to shut down at 40°C.

Normal temps for your CPU a very healthy CPU :-)

Download and run MEMTEST to verify your RAM. It's a common cause of problems.

My computer failing turned out to be that my BIOS was setting RAM timings incorrectly so my RAM failed Memtest. An updated BIOS solved this.

I ran Furmark and my computer shut off after 30 seconds. Could it be the GPU causing the on and off cycle?
I have a GTX 580. These are the settings I used.

The max temp was around 65C.

Your temps are very good. Many people have worse.

Lol! nice edit btw!
Your temps look pretty good to me.
If you're experiencing random shutdowns it could be a few things.
1.faulty ram = run Memtest86+ and test ram one stick at a time at mobo defaults
2.gpu drivers
3.inadequate power supply

The most likely reason for the shut downs in the powersupply. Does it just restart? Do you get bluescreens?

:)  The only thing I added was the 3 seconds.

It has turned on for up to an hour or so and then it will turn on and off and on and off. I think it actually might be my wall socket because when I brought it down stairs today it worked fine until I ran FurMark but after a restart it worked fine on Battlefield 3 max settings and never shut down or anything. I built it on Friday and it worked fine until Monday morning.

Okay so I tested the RAM. I got Corsair Vengeance RAM. It says it should run 1600MHz and 9-9-9-24. The settings that Memtest86+ showed on the first stick was 664MHz and 9-9-9-24 the second showed 665MHz and 6-6-6-24. PC3 on both was 10600 and it says it should be at 12800. This is the exact ram I got. http://www.newegg.com/Product/Product.aspx?Item=N82E168...

This is what Memtest86+ showed under settings.

Settings : RAM : 664 MHz (DDR3-1330) / CAS : 9-9-9-24 / Single Channel

Second one

Settings : RAM : 665 MHz (DDR3-1330) / CAS : 6-6-6-20 / Single Channel

1 Pass each, no Errors.

Those settings make no sense at all to me.
To test the ram it will default 1333MHz which is what you want.
You have to test the ram more then one pass btw.
Looks to me like your bios is messed up.
Ram timings are mismatched.
I'd reset my CMOS and bios to factory defaults and re-run the Memtest for 30min. at least.
Test each stick one at a time first.
Re-test as a set for at least 30min.

I will do that.

Could a faulty fan cause this? This started happening the morning after I changed a fan in my case.

Also, thank you so much for helping me out!

Np, that's what the forum's all about.
Changing a fan shouldn't cause issues.
I hope you understand what i mean by reset/clear the CMOS.
Some motherboards feature a button or otherwise you simply pull the battery out for a minimum of 5 minutes.
Always turn off your rig,turn off psu switch,unplug power cord,and depress the case power button before entering the internal area.
Ground yourself by touching a metal part of the chassis or the psu with one hand.
Once you've reset the CMOS/BIOS turn the rig back on.
Go into Bios and set to factory defaults.
Then proceed with Memtest and further troubleshooting.

What do you mean by depress the case power button.

That discharges all the capacitors in the pc.
Capacitors hold voltage(power).
Case power button = on/off switch on the front of your case.
