i5-2500k temps too high?

[neocpp]

Hey everyone, I'm new here but I've been following anandtech for a little while and recently bought an i5-2500k with the asus p8p67 pro motherboard. I've been looking forward to OC it, but I've run into a bit of a problem... my temps seem way too high! I'm just using the stock cooler, but I'm scared I will destroy the chip if I attempt any sort of nontrivial overclock.

My system at "idle" runs about 47/48 deg C (this is with like ~2% load). I've actually been afraid of running Prime95 at all, since in 60 seconds the temps climb to 90+ deg C (at this point I get worried and kill it). Prime95 seems to make the temps jump a lot though, as under other types of 100% load (gaming, matlab) it gets to around 78/79 deg C. Still not good, but less worrisome. I've been measuring these temps with Core Temp and hwmonitor, and they seem to agree. Speedfan gives some wacky numbers that I'm not so sure about (70 deg C at idle...). The uefi bios seems to agree with core temp and hwmonitor, as whenever I go in there the temp reads at around 52 deg C.

I'm running in a cooler master elite 334 case, which didn't have any temperature problems with the previous setup with a Phenom II.

Am I doing something obviously wrong or is my chip just really sad? I doubt this is normal, at least looking at other people's temps. I've reapplied the thermal paste twice (with arctic silver), but the temperature hasn't varied that much under load or at idle (idle was a little higher at around 53 deg with the pre-applied stuff). I'd buy an aftermarket cooler for an eventual overclock, but I'd first like to figure out if I need to RMA my cpu or mobo before doing that.

Hi there and welcome to Anandtech. (Well if you've been lurking here for some time, then welcome as a registered member)

Of course - have you updated to the latest BIOS update from ASUS and set everything back to factory default?

The only thing that comes to my mind immediately is that your cooler is not seated correctly and a there is a possibility that one (or more) of the 4 twist-push pins are bent or damaged causing the cooler not to sit flush. I've always hated the current stock Intel cooler design since I saw it first on the LGA 1366 and will continue to do so.

I would love to give other opinions - but I unforutnately haven't run into any problems with my i5-2500K myself with my own P8P67 board. 90+C on load means something is horribly wrong.

Thanks, glad to be here

I've updated to the latest stable Asus bios (1003 I believe), and set everything back to factory default. Followed your suggestion for the heatsink seating and everything seems okay (reseated just to be sure, nothing changed), so I think I'm just gonna RMA.

Is it possible the temperature sensors are somehow just miscalibrated? My gtx 470 is supposedly running a lot cooler at 70 degrees C when gaming, but I notice a lot of warm air coming from the back. The air from the CPU cooler doesn't feel nearly as warm. Then again I'm not sure how good the cooling solution on the gtx470 is compared with the intel fan+heatsink, and how much thermal energy each outputs, etc. Obviously I'm still RMAing, but I'm just curious if anyone else has had similar problems. Batch number is L041B800 for future reference...

Anyways I am glad to hear that you have had no such problems, hopefully when I get a new cpu everything will be working properly.

Good luck with your RMA.

The latest BIOS update for the P8P67 is here which is version 1253 FYI

As for on-board temperature sensors - I never fully trust them as many enthusiasts don't either. If you have a couple of bucks to spare, a probe sensor or a infrared sensor gun will last you a long way into the future for various projects. You might want to check out one below on the cheap right now from Amazon

Let us know when you get your RMA back how things go. Sandy Bridge right now is still young so more information is useful information.

My i5-2500k runs around 32-35C idle and around 55 to 65C running prime95.

 

[Axon]

My 2500k idles between 40-50c and hits 69c or 70c on one core after an extended Small FFT run. There's that one core that's always 5c hotter than the rest and is the culprit.

Anyway, your temps do sound high.

Should have tried more methods before RMAing. Resetting the cooler or different thermal paste also.

 

[djshortsleeve]

I have the same board and CPU, right after the build it was in the low 30's, the last few times I checked its been idling in the high 30's (with CM Hyper 212+.

 

[CosmicMight]

Temps are way too high. My cores range between 26-31 at idle with an oc to 4.3. Prime95 with that oc is 56-59.

I don't think the RMA was a bad idea, but I do hope you are investing in a quality CPU fan and properly applying thermal paste.

 

[Anomaly1964]

Will temps drop even lower once you have everything in the case and all the fans blowing?

My i-2500k was running at 39C in my "build to post..."

Edit for wrong quote.

The sensor can be broken, but that doesn't look it is the case. First, the sensor is not a thermometer, the temperature on screen is just an approximation to temp as the sensor only measures how much degree until the system starts to cut clock and shutdown. In short, it is not an accurate thermometer.

Having said that, jumping 50 degree in 60 second indicates that the heatsink isn't doing its job properly, plus the fact that you said the air is cool further convince me that the contact betweeen heatsink and the CPU is not done properly. Can you tell us what procedure you did just before you mount the heatsink on the CPU?

There was something underneath the heatsink which looks like a cheese, did you removed it? When you remove the heatsink, did you reapply thermal paste?

 

[gevorg]

OP, those temps are high but like said previously, make sure that the heatsink is properly sealed/mounted and a proper thermal paste is applied.

My temps in midtower Antec Solo case and stock speeds: 29C idle, 48C load (30min after prime95). I'm using the Scythe Mugen2 cooler.

Idle temps are not really important. What are your load temps?

I'll let you know once I finish building...:thumbsup:

Well, you're ahead of me. I finally ordered the rest of my parts today. That's what I get for piecemeal bargain-hunting ^_^

And yes, a case with good airflow helps (especially under load). That's why I bought a large case with lots of ventilation (Lian Li PC-A77FB). This thing moves much more air and is much quieter than my old PC-65B.

Temps in the bios will show higher temps than in windows using programs like RealTemp. 39C in the bios will translate to about 30C in windows. Had the same issue with my p8p67 pro build.

 

[tweakboy]

Well my friend the thing is once your CPU gets hot enough if automatically shuts down your compoter to prevent damage. I dont know what your TJmax is , but Im guessing at 85c your system will shut down. For idle that is way high. Im sure your full load gaming takes that 49c to close to 90c or TJmax... take off the heatsink clean the cpu and heatsink and reapply artctic silver or thermal paste, make a line horitzonally on the CPU and another vertically and put on the heatsink make sure its tightly in and watch the RPM its going at. with numerous apps like speedfan , or Aida etc etc..

I dont know if your CPU has a offset so what you see in speedfan are your real temps

 

[Manticorps]

I don't think they processor downclocks in BIOS, like it does in Windows so it will run a little warmer.

I think the OP needs to remount the Heatsink, those temps seem way high to me.

30C idle, 70C load.

Thanks for the replies everyone, I've tried reseating and such, reapplying thermal paste, pretty much everything I can think of, and the temps don't change that much -- a degree of difference or so, what I think is statistically insignificant.

The first time I just placed the cpu in the socket, took the cooler out of the plastic holder, and used the pre-applied paste. I pushed the pins in in a diagonal patten (didn't clean cpu or anything, I didn't notice any type of cover on the heatsink thermal contact or cpu).

Second and third time, took off heatsink, cleaned cpu and heatsink mount with isopropyl (90%), waited for it dry, then put a rice grain sized amount of arctic silver 5 in the center, spread it around with some plastic thing I had. Remounted cooler the same as the first time. I did notice that one of the pins didn't seem to lock as well as the others (didn't give a strong clicking feel), but I couldn't move the cooler after everything was in place.

The replacement CPU is coming in tomorrow, I'll let everyone know how that turns out.

As an aside, are some of the pads on the cpu significant different colors? I haven't had an LGA cpu before, so I didn't know what to expect, but I noticed that with the specific processor I bought there appeared to be 'burn marks' on some of the pads. I figured it was a side effect of the testing/binning process, but I'm beginning to think it may be consistent with increased current draw (and correspondingly higher temps). The system runs stable, just hot as far as I can tell (so maybe testing would put it within parameters?). I bought the CPU new, so I'm not sure how else the 'burns' could happen.

 

[Dadofamunky]

Nah, in my experience they're all the same (CPU pads, not women)

 

[Muscles]

I might as well chime in with my results. I recently just built my new rig containing the i5 2500K stock w/ASRock P67 PRO3. I'm using the stock cooler and my idle temp is around 35C and running prime95 on all 4 cores it sits at 65C.

The bottom line is the stock cooler is pathetic.

 

[rstrohkirch]

I threw some arctic silver ceramique I had laying around on the stock cooler and it dropped my load temps by about 4-5c.

 

[Mennovh]

Just wanted to chime in my temps as I just built my system yesterday. I havent OC'd yet.

At stock with a cooler master 212 my idle temps are around 28c and prime 95 the hottest core topped out at 38c. Also have a Cooler Master HAF full sized tower. The thing moves so much air it causes a slight breeze in my living room.

 

[robkenbat]

All very curious. I've just built an i7 2600 sytem with the Asus P8p67 mainboard. Yes the BIOS temp creeps up to a high idle temp of 51 C. Checked and done everything discussed above, but still the same reult. Installed 'Core Temp' software and CPUthermometer. Both show an idle spped of 28/30 C idle and 45/50 C load.
I wonder if the Asus bios temp guage is any use?
I really do hate the cooler 4 pin fixer sockets setup for both AMD and Intel!!
