Windows 7: i7 2600k overheating.

Yep software conflict between Asus suite and hardware monitor, I downloaded both on my laptop same problem, tried one without the other, as there's a few sites on the net saying there not compatible. YAY!!

Now im kind of wondering if my cpu cores have been getting up to 70-90c.

Are the cpu cores always hotter than the cpu itself?

I have a system configuration similar to yours.
I use the Hyper 212 plus with artic silver paste. I use one supplied 120mm heat sink fan. I have a well cooled case. I am not overclocking.

1) On a warm day with running Prime 95 for ~30min or Handbrake near 100% on all cores my max core temperature is in the high 50 C. One core always records ~6C higher than the minimum core. I have reseated twice according to Artic Silver guidelines and the difference still appears. I'm not bothered.

2) Probe II run in conjunction with say HWMonitor can record very brief "Voltage glitches". I ignore them as an artifact.
Fans take little power and you have quite a large PSU. Unless it's faulty I think you are seeing an artifact.

My 2700k has core 2 thats approx 6C higher than the other 3 as well.
Reseated the HS and it didnt help. But after some looking around, it seems this is quite normal for the i7s to have one core always run a bit warmer. Odd.


At any count, thats why I suggested the 212.
Its a fine little cooler for the price, and even if you OC a bit itll do the job quite well. As a replacement for the stock its pretty amazing in comparison.

You really only need a bigger cooler if you plan on heavier OCing, or simply want something with a bit more flash.

On my system the core temps are always 10-15C higher than the cpu temp with any program I've tried that reads cpu and core temps separate.

I believe the core temps are the ones you should be concerned about as I have experienced problems, freezing, instability, when my cpu temp reported by PC Probe is around 15-20C less than max meaning my cores are pretty much at their max temps.

Generally different cores will experience different temps because different cores experience different loads depending on what your doing.

Tcase can be ~5-10C less than Tcore so you need to know what you are measuring. Most temp measuring programs use Tcore. This great post suggests 5C but I seem to find it closer to 10C

ASUS BIOS releases above (v501 I think) on my motherboard decided to go from Tcore to Tcase without notifying users. Unfortunately they didn't change their temperature control curves. I gave up with ASUS technical support area. I clearly defined the problem and I don't think it ever got passed up the line.
Also, I am aware that the temperature readings in the BIOS are higher than normal out of BIOS ambient. This is not the issue.

From my understanding this is because the TCase is nearly impossible to measure via software. And the sensors can not accurately report it.

If I recall correctly, the Tcase for the i5/i7s is supposed to be 72 or 73C.
I too have always felt the Core or Package CPU Temp is normally 10C higher than the actual Tcase, as a fairly close estimate.

Nice info thanks.

And just because I feel like it, right now in Hardware Monitor mine has CPUTIN = 33C, Core 0 = 47C, Core 1 = 46 and from indoor thermometer Room temp = 26.9C.

CPU load from Task Manager = 1% - 10%.
CPU Fan = 1100rpm, One Case Fan = 1240rpm, Other 2 Case Fans not monitored.

Thats 14 and 13 degrees difference.
Not overclocked at the moment.

I'd check that CPUTIN in HWMonitor (or SIW) is giving a meaningful reading.
Mine always reads 60C=nonsense.

It's the same temp thats reported by PC Probe and AI Suite. If you think it's low, I have Intel Speed Step enabled and because my CPU usage is low I'm only running half speed. I also only have a E5200 CPU with a decent heatsink and fan combo.

Hello! Thought id come back and give those who helped me an update

The Highest ive seen the CPU temp go with this new cpu fan is 45c playing batman arkham city.

The only thing that worry's me is when I start up my computer, i get a message saying cpu fan error!

The cpu fan has been at around 500-600 RPM, its in red on my bios but the tempatures ive been getting seem to be fine, is this normal? thanks



Also dont ask about the whole hellboy thing :P private joke.

Hi, I have bought my computer something like 5 months ago. It has recently come to my attention that its reaching very high temperatures, such as 70C during mild stress. I do mean mild, as games aren't very CPU intensive. Yesterday i cleaned it, of all the dust, and it went from 70 to...
