CPU temperature

[Ragequits]

Hello everybody!

I'm using an old first generation I5 660. It is only a dual core and quite old so I tried to overclock it. Since I don't know anything about OC I used my motherboards "OC Genie".

Now it clocks at 3,7 GHz instead of 3,3 GHz. The highest recorded temperature so far is 56 C°. Usually it is between 50-54 C° when it is under load.

Coming to my questions:

1. Is this temperature okay or does it hurt my CPU?

2. How viable is this CPU? (im planning on upgrading my graphics card since it is a real bottleneck)

If that is under full load (100% CPU utilisation) and say after at least 15min of full load run (not just few min run) then those temp's are still alright. I would not let it get to 60°C, that would be my limit.

 

That will shorten the CPU life, but as it's old CPU anyway who cares? If you kill it maybe it'll push you to do an upgrade ;)

Thanks! It wasn't at full load when I tested it but the temperature was stable over the whole hour i played. So it seems like the settings are fine.

If I had the money to buy a new rig I already would have done it :P

But unfortunately I'm just a student, who has almost finished school and wants to go to university.....so I rather safe my money for more important things ;)

My 4790K runs at 35-40C when its not overclocked (4.0Ghz), and around 56C overclocked to 4.8Ghz. I do run a water cooling system but those temps are well within your requirements.

First, be sure your temperature is accurate. You should use 2 software (coretemp, HWmonitor) to compare.

A cpu will not degrade by the temperature but by the voltage of the core.

So far I used MSI Afterburner to view the temperature...but I'll check it with these softwares too.

I always thought the rising temperature would damage the PC component:music_whistling:

But in this review you posted they overclocked this prozesser with a stock cooler to 4,2 GHz. Since my cooler should be better I'll try it soon with their values. Thanks for the tipp!

If the pc components can be damaged by the temperature? Yes.

But the cpu has a protection. It's not 100%, but it works.

 

Go easy with the cooler. High temperature can generate a lot of errors. Freak out your bios...

Msi afterburner on my pc way overestimates the CPU temp, it says 70 when all others (hwmonitor, speedfan, realtemp) all say around 40. So it's definitely worth getting a few different temperature checkers to double check.

To make sure everything is really stable and your temps are in order, use IntelBurnTest to stress test the oveclock, and use CoreTemp to check CPU temperatures. These two tools are most reliable dor this.

 

And yeah, it's the increased voltage that shortens the lifespan of the CPU.

And yes, the temperature can damage the chip during a long period of time. But the BIG part of the cake goes to the voltage.

Modern processors are very heatproof. The Ivy bridge can safely run a game at 70-80deg.

 

That's better. Sorry for the rudeness. :tomato:

Technically speaking you can go as high as 80-90 degrees no problem , but it will shorten CPU life (it might die after 10 years of use...)

if the temp is too high , then the CPU will throttle down for safety.

so what you want to do is push it to the maximum clock it can hold under full load for 15-20 mins without crashing or throttling down.

 

unless you up the voltage too high , its practically impossible to kill a CPU.

You can also invest in some AIO Watercooling that fits your old socket as well as the newer and newest ones. The H100 or H110 do a pretty good job for the price. The included fans are VERY loud, you might want to use different ones from day 1 on....

It is impossible to kill a CPU unless you disable hardware thermal control.

You can actually unplug the CPU fan on intel chips and they will downclock and undervolt to keep from hitting thermal limit or just shut down.

 

Additionally use error testing software like OCCT's Linpac test to really see if your CPU will get too hot or is OC'd too far and causing errors.

Just because its not overheating doesn't mean everything is OK.

Linpac is what intel uses at the factory to test CPU's.

An hour of OCCT's CPU: linpac test at 25% memory setting is sufficent to ensure stability.

No problem :)

I personally don't think this would be resonable. Of course i could push my CPU even more but it would wither even faster since the voltage seems to be a big CPU-killer. Moreover, I then probably need to buy a new power supply for my pc.

 

So I tried as suggested testing the CPU with IntelBurn while monitoring the temperature with CoreTemp and MSI Afterburner as a backup. I also took a look on how the coreclock an voltage changes via CPU-Z.

First of all: The OC via OC Genie is utter garbage

Compared to what I set in the BIOS myself it seems to heat up the processor more than my settings because of a higher voltage while beeing slower.

I've set the CPU (for testing purpose only...so far) to 4GHz. Temperature is now around 60C° when running IntelBurn. Voltage at load is now at 1,3V instead of slightly over 1,1V (this is without OC).

The bios actually lets me oc the CPU to 15GHz....this will mostlikely melt the CPU instantly regardless of what type of cooling you have attached :D

 

And a big thank you to all of you guys!:) I'll now try to optimize it a little bit

You're not even close to overheating anything.

CPUs generally begin throttling at 72 degrees Celsius.

At that time they dynamically decrease efficacy so no overheat occurs.
