Is my CPU running too hot?

Yesterday I reseated my new i5 2500ks stock heat sink using the vertical line thermal paste method after it was overheating and making my computer shut off.

Now it's idling around 30-35c degees but when I open a game of Bad Company 2 in a server with no people the temperatures of the cores go up to 62-70degrees. Is this bad or too hot? It was only yesterday I applied the paste so it still has to break in. I don't really want to purchase a new cooler until I need to.


Also.. when I was wiping off the thermal paste and everything using the articlean stuff when it was all said and done I noticed a thin black line about a cm long on the top of the CPU. It woudn't come off so I guess its possibly product of the overheating? Could this have any harmful impact on my computer (ie. explode, start a fire, idk lol)? Could it affect performance?


Thanks!

Idle and load temps look OK for a stock Intel cooler.

What kind of idle and load temps were you getting when the computer was shutting down?

It doesn't seem likely that your CPU could have survived any thermal event that got the CPU heat spreader hot enough to leave a mark. More likely it was that way since it's initial installation. Was the area around the mark still very flat? If so, it's not likely going to be a problem.

Well maybe I should fix what I said.. when it was flat out shutting down I found out the cooler wasn't pushed in correctly on all side. I did that. Then idle was around 45
And I'm not sure but I think Bad Company put it in the high 70's even 80's.

So after reapplying it I'm getting around 10c less. And not sure but with the thermal paste break in period how much lower it'll go.

Also I wouldn't plan on OCing unless I got a new cooler.

Having a Intel push pin cooler without having all the pins seated can allow overheating.
Fixing that was probably more important that adding new thermal compound.

It won't go much lower but low 70s is OK while gaming.

How could it go any lower just curious? Would I have to reseat the HS again?

Also any word on that black line on my processor?

Is your CPU overclocked? Then you may want to install an after-market cooler, such as Cooler Master Hyper 212 Evo. I have an older version 212 Plus over i5-2400, which keeps the CPU temp under control with silence.

If you want to keep the CPU temp lower, you may want to change the fan speed-cpu temp profile on BIOS. My MSI board has option to set a target temp, over which the fan will speed up to keep the actual CPU temp low. Currently I set it on 50C, and the actual CPU temp barely go over the target even playing Skyrim on Ultra 1080p, so I don't hear the CPU fan sound usually.

The best way to reduce load temps is getting a beefier cooler. The Hyper 212+ MKBL is good, very popular and inexpensive. Just make sure it will fit in your case.

CPU coolers do their best work in a well ventilated case.
What case are you using? What type and how many fans does it use?

Hi,

What program you use to monitor your temps ?

In fanspeed you have to consider core and cpu as 2 different things:

cpu temperature is the one your interested in: if it goes up to more than 80 degrees full load their might a problem.

core temperature is always higher than cpu temperature.

I wouldn't even bother with it.
( I had core at almost 100 degree but never had any problems on e8400: their might even be off or have problems )

BTW the cpu is still running fine

Sorry just saw your post.

I'm using the HAF 922 and the fans that come with it.
Yeah it seemed smooth just when I tried to remove the black mark it wouldn't disappear.

HAF 922 and it's 3 standard fans won't have any trouble getting rid of the warmed air in that excellent case.

Well that's good! Still curious about the CPU monitor thing. How is the "CPU Temp" dif than Core temps? And if its the same which core do people usually go by? For example when I google idle temps and things like that people say one number then 4 different numbers.

Core temp reads temp on each core, and CPU temp on whole package. There shouldn't be big difference among them. For example, when my PC is playing Skyrim, the max of CPU is around 48, and the max of each core is between 45 - 49. Again, that's the max of each, not at the same time necessarily, though. At a given time, one core, particularly #2 (#0, 1,2,3) stays 2-3 C higher than other cores. I would be concerned if any core has more than 10C difference with others. That means the hotsink is not aligned correctly.

Uh oh.. my core 2 is actually almost 10c LESS then the others!

Heres a pic of my CoreTemp.

The heat sink seemed like it was pushed in all the way and even..

You can take the right side panel off to look at the CPU mounting plate to confirm that all four pins of the CPU cooler are evenly pushed in.

If the workloads per core aren't equal it's not unusual to see variations in reported temps.

That - is definitely not a problem. Visual confirmation that the HSF is installed correctly, also confirmed by the temps being under contrl.

So by that you mean I'm good? Wonder why mine seems hotter then the average i5.. or atleast thats the impression I'm getting.

when the cpu temp hits 70, what is the fan speed? Rpm/%

if fan is not running fast enough because of pwm setting, cpu temp will go up, even with my beafy cooler.

Also when you reseat the heatsink, did you clean the bottom side of it as well as cpu thermal plate?

It seems that 70 is not a bad sign with stock cooler. if you are still bothered, just go get cm hyper. don't you value yor peace of mind over the price tag of mere $20? Based on your posting, I think you won't be fully satisfied with any answer here saying that it 70 is ok.

It's not that I'm not satisfied.. it's just I want to be sure and understand that it'll be okay.

Yes I used articlean on both the top of the processor and the heat sink.

I'm running Bad Company 2 right now with the temps at around 65
and the fan is around 2340 and has been continuing to rise


Edit:

So I just closed Bad Company 2 but before I did the fan had gotten up to 2500 and seemed like it was still going to go higher possibly.

What % of max is 2340 RPM? My fan PWM setting is 12.5% @ < 50C, which turns the fan @ ~780 RPM. I don't know about stock cooler, but still >2000 RPM seems fairly strong, though.

I don't know what answer you are looking for, but WR2 and dextermat already said your temps is normal. I can't come up with any better answer you will get here. Somebody @Intel said you don't need to be concerned unless the temp stays 90 constantly, but I didn't feel comfortable with going too high (even before experiencing it), which led me to the CM Hyper 212 plus from the get-go, and at least one possible root of worries (my wife calls me worrier) is gone.

70ºc its ALOT, you should stay in 40-50ºc range to get a good stability over the time, thinking on future years!

Love how stock coolers are useless. If you can get aftermarket cooler for $20-30 it would be much better than stock. Anyway if money are short just add another fan on top of the stock one to blow directly on it...also make sure that your case has good ventilation if not take a side panel off and enjoy the games!!!

If you're gaming for several hours and the temps are staying in the low 70s that's not a problem.

Hotter than 'average'? Not really, not for a lightweight CPU cooler.

So back again! Ended up getting a CM 212+ ..wow I really didn't like the installation process for that.

Finally managed to get it done though.

Heres my CoreTemp while running Prime95 for about 5 minutes.
http://i43.tinypic.com/2417ak1.png

The idle seems about the same.. 30-38c ish
But running bad company the max I've seen so far is 54c.

Is this good? If I planned to over clock (don't plan to right now) would I need to remove the heatsink and reapply the paste or is this a good and respectable tempature to oc later in the future?


Edit: Also Core #2.. for some reason it likes trailing behind the rest.. it's still several degrees below the others and at idle I think I saw it at 23 at one point while the rest were around 35.

70C to 54C is a great improvement.
It's good.
Don't do anything else. Just overclock it when you want to test it out.

No problem on core 2. It's better to trail than to lead.
