Lately I've noticed that my CPU temp has been running extremely hot when sc2 is running, and now that I'm looking at the temps while its idling they also seem too hot.

CPU temp while sc2 is running: 90-98*C

CPU temp while not under any heavy load: 48-52*C

[image loading]

As you can see I just recently ran sc2 (about an hour ago) and the temp spiked up to 98*C.

It is a i5-2500k sandybridge proccessor, OC'd to 4.4ghz while under load, and at 1.6ghz while idling. It is using the stock CPU fan on it. I've never had a problem with the CPU overheating until recently, and I've had it for about 2 years now. I've blue screened twice in the past 3 weeks from what I believe is the CPU reaching its 98*C threshold and shutting itself down for protection.

I have a pretty good airflow designed case (Full tower coolermaster), I've cleaned the inside case of all dust just recently as well.

I tried setting up vsync, which didnt solve anything. As well as adding the

frameratecapglue=30

frameratecap=60

lines to the variables.txt, which didn't help either.

PC specs:
CPU: i5-2500k
GPU - Nvidia GeForce GTX 560 TI
Windows 7 64
8GB ram

Any help/advice would be great appreciated T_T

Did you take the heatsink of your psu lately? If so try to re-apply some thermal paste to that, I had some minor overheating issues was getting some blue screens and that helped out quite a bit

You didnt mention it, so how did you overclock? What voltage are you using.

You probably have to reseat the heatsink (you do have an aftermarket heatsink and did test the overclock somehow and use a sane voltage, right? If you're using auto voltage on stock cooler this would totally be expected)

The lack of key information in your post is concerning

It is using the stock CPU fan on it


Ahh yea. Not sure if i didn't see this, or if you edited it in.

When you overclock you are supposed to stress test and be careful with voltages, increasing them to what you need but not too much, monitoring temperatures while checking for stability etc.

When you say that your CPU is OC'd at 4.4ghz under load and 1.6ghz idle, do you mean you have intel turbo boost on or some kind of other dynamic OC? Also, don't be surprised to see those temp if you run your CPU to 4.4ghz with stock cpu cooler... I'm not expert when it comes to OC but this definitely seem to be your problem.

It sounds like your going about overclocking the wrong way. You want to configure your hardware such that it can handle any amount of stress. you should not be tweaking your software to reduce the amount of stress it puts on the CPU for the sole purpose of preventing overheating.

Coretemp reads 1.36 VID, if he's using auto voltage and it's using that, then he might as well be running 4.8ghz with manually set voltage temperature wise.. on stock cooler

You shouldn't be overclocking with a stock CPU cooler in the first place.

I overclocked it in the bios to a x44 multiplier using a 1.35voltage. I'm not sure if I'm using the turbo option or not, but when its idle its only 1.6ghz, and under load at 4.4ghz. I had a friend help me and that was over 2 years ago. Like I said its been perfectly fine being overclocked with no problems for 2 years now , it just started happening these past 3 weeks.

Just bought an aftermarket heatsink, so after I come home and set it up ill test the temps when running sc2

This is far too high most likely, it's a kinda extreme voltage.

Just bought an aftermarket heatsink


Which one?

And it won't fix broken settings - maybe bandaid them. You should be able to fix settings relatively easily.

What would you recommend I set the voltage to? I get list relatively easy in the bios as I am a big ametuer when it comes to this. And I assume I should turn off the turbo or w/e that changes the settings from 1.6 to 4.4 depending on load?

As for what aftermarket fan I bought, its not great but definitely a step up considering It has those pink/orange pipes coming from it, which the stock one doesn't have. Its a rocketfish.

What you set the voltage to is dependant on what you need for the CPU to be stable, and temperatures; It's a bit worrying that you don't know this stuff, running an OC. Try something for example 4.2ghz 1.2v, and you should download Intelburntest and cpu-z to stress test and observe settings. Stock cooler is designed for stock settings, not overclocked

Steps to overclocking for sandy bridge

1. Set a goal frequency(somewhere between 4.0-4.5 generally)
2. Set voltage to 1.2
3. Try to boot
4.a. If successful, go stress test
4.b. If either fail, increase voltage by .005

Repeat until success, or voltage/temps goes above what you're comfortable with, in which case lower the goal frequency and restart.

Nobody can tell you what a good voltage is for your processor. My 2500k is older and rather power hungry and doesn't overclock particularly well, so it takes ~1.28 for 4.3, ~1.3 for 4.4.

You don't have to turn off turbo, although it makes things easier when off.

Okay thank you, i'll try this. I'm going to install the new heatsink now and then stress test. Is that intelburntest or w/e the best one to use for this situation or?

It's pretty much the best for basic stress testing or finding a ballpark overclock quickly.

Make sure you use thermal paste correctly, most people use far too much, or apply it in the wrong way

I installed the new heatsink and then set up the overlock to 4.2ghz instead of 4.4. Although I didn't change the voltage because I kept enhanced intel speedstep technology on, so its automatic. Is there a way to set up the ESIT so that the maximum voltage it goes up to is 1.2?

Anyways, I ran the intelburntest v2.54 and these were my results: Ran it 10 times under the standard 1024 mb stress test, kept my cores at 100% until it was done and the max temperature was between 75-81.

On a side note, I'm running sc2 now and the temperature of my cores is staying between 38-49 degrees, fluctuating randomly. Definitely an improvement, is this normal now?

This is the heatsink I'm using now, its roughly 2-2.5 times the size of the stock one I was using: [image loading]


I just don't understand why it took 2 years for my cpu temperature to start increasing and giving me problems -_-

Pretty normal, suprised everything was fine for any period of time on auto voltage OC + stock cooler.

You should really optimize overclock, set a manual voltage and drop it until you start to see failures in stress testing, then raise it a bit - right now and with auto in general, it's just taking a wild stab in the dark at what voltage you need, probably using far too much, so you have much higher temperatures than neccesary. You can probably run 1.3v no problem - and manually setting and overclocking, that's likely to get you 4.6 or 4.7gz without temps leaving the upper 80's

Thermal paste dried up probably, especially if that was the default one. One my mate had a similar problem not long ago, his CPU temps (stock clocks, stock cooler) suddenly went up by 30C+, to low 90s from mid 50s-60s in games. After I applied a new thermal paste it went back to normal temp and even a lil bit lower, because stock thermal paste sucks.

Also I'm not so sure it's a nice idea to go for 4.7GHz+ with this cooler. Maybe that's just me, but I prefer to keep CPU temp below 70-75 at IBT. Unless you've got some damn good chip though.
P.S.
Wanted to ask why you have such low GFlops, but then remembered about the difference between win7 without and with SP1. -.-

Most people dont do that, i'm not sure about sandy bridge but i think current temps are fine; Can just do some fine tuning, there's no reason to use such massive voltage for 4.2ghz (or more for 4.4)

Can either increase clock speed or decrease voltage
