Core i5 Serious Tempurature Rise

Hello, Hoping for a clue here. New build done. Core i5 Sandy Bridge on Asrock P67 Extreme 4 G3. Stock CPU fan installed.
I see 92.5• C within 2 minutes of hitting power button. No loads, no nothing but get into BIOS to monitor.
I applied thermal paste according to demos online. Wasnt sloppy, cleaned w coffee filter after "conditioning" no scratches, mishanding, or anything odd happening outside of normal.

I am shut down now after reading what normal temps are for this processor. 40 idle and around 60-70 loaded (?)

But 92.5 • idlde!!! Help...I need clues. Bigger fan? THANKS FOR YOUR TIME ANSWERING ALSO.

The CPU runs at full speed while in the BIOS. SpeedStep actually does not kick in until Windows is loaded. Therefore, I recommend that you simply boot into Windows then download Core Temp (google it) to monitor your CPU's temps.

Your voltage sounds like it may be too high. Have you oc'd this yet? The stock cooler isnt great for oc'n, if you are in fact doing so.

Just to be clear you applied paste then wiped it off then re-applied? So there is paste on there now?

Yes,,paste applied, sorry that was confusing. Will investigate voltage when I get home in an hour. What s the draw on that i5 processor anyways?

i5 Voltage typically runs 1.15-1.25.

Get cpuz: http://www.cpuid.com/softwares/cpu-z.html

Run this while web browsing, streaming, gaming, etc...and pay attention to what it does. It will show you the Core Voltage and when under load you can see what the voltage ramps up to. Do this and let us know the voltage fluctuation. So if just on your desktop/idle and its a .98v then you open a web page and it jumps to 1.4v. Also, is this an i5 2500k, 2500, 2600k, or 2600?

stock CPU cooler and too much thermal paste..
my first quick opinion..

what is the fans and direction of fans set-up with your unit.?


Stock fan that came with processor.
Clockwise

CPU Temp 92.5C
M/B Temp 22C

CPU Fan 1 Speed 1912 RPM

Vcore +1.13 V
+12.00V +12.302 V
+ 5.00V +5.160
+ 3.30V + 3.392

What is the CPU temp according to Core Temp when you are logged into Windows?

Man, Now windows just sits there "Please Wait" while booting up. I had a successfull version update on the Crucial M4 64GB SSD last night. Hey Man, I gotta go run an errand...I'll be backk on this evening....THANKS FOR YOUR HELP. THIS IS DISHEARTENING. Everything went smoothly until I noticed the temp

remove your heatsink see if the paste is actually touching both surfaces. It sounds like you may have put too little paste on.

Got Core Temp......Tj Max was at 98º C Cores 0,1,2,3 were at 36 to 38ºC
Voltage was 8 Watts. Im going to pull the stock fan off and see whats underneath. One forum fellow says too much thermal goo, another says too little. How will I know here?

voltage 8 watts...?
cores: 0,1,2,3 36-38C is good temps there..



CPU-z report says core voltage 0.976 V.

Is that Tj max reading of 98º valid if the seperate core temps are reasonably normal?

I need help sorting all this out....confusing. Do I really have a high temp problem or not?

2 sources - one the MOBO BIOS, and another, Core temp say reading into the 90's C.

What to do first?

TJ MAX is basically the temperature at which the CPU would start to throttle down your CPU to prevent heat damage. It is not an actual temp reading.

If those are your temps, then you really have nothing to worry about. As I stated before, the CPU will run at full speed when you first turn it on until Windows is loaded. At that point SpeedStep will kick in and lower the CPU's speed to reduce the temperature.

Load up a game and play it for a while or do something that really stress the CPU like video encoding take note of the max temp readings. I do not have a core i5-2500k, but at stock speed and under stress I think the max temp with the stock heatsink/fan should be around 65C.

WHy would the MOBO BIOS state core temp of 92.5 C then? Isnt that worrisome? Thanks for your help also. First build and learning if you cant already tell. Learning fast at that.

Im sorry.......Mobo Bios states CPU TEMP is 92º C....sorry sorry sorry.

Because when you are in the BIOS the CPU is running at full speed.

The BIOS is not Windows. From the moment you turn on the PC until you get to the Windows login screen, the CPU will basically be running at full speed.

alright... Im feeling better.....you would trust the individual core temps of 36º-40º for 0,1,2,3 using that Core Temp Utility? Thanks for staying up for this also.

Those temps are fine when idling.

You wanna check your temps when the CPU is under stress. Like I stated, it should be around 65C from what I remember of the reviews I've read months ago.

way too hot still.
it shouldn't be running at 92C when in the BIOS though...
are you sure your reading that correctly.?

I took a picture of it. Im sure Im seeing it correctly.

Yeah, 95 is too hot even for BIOS. Either you have serious heat issues or the tcase sensor on your CPU is bad. I have an i5 760 with the stock cooler and my BIOS temp caps out at 46 degrees celsius. As said above, try loading up your CPU in Windows and see what the core temperatures are. Somewhere between 60 and 70 degrees is acceptable, though not great. If it goes higher than that, especially on a lighter CPU load like gaming, you need to try to remount the stock cooler with new thermal paste. If that doesn't get your temps down to an acceptable level; you may have to look at aftermarket cooler.

I downloaded a couple more utilities one being the ASROCK eXtreme AXTU.
CPU temp there reported in at 40º C. Core Temp gave each core 35-40º C.
Im beginning to relax some with each utility reporting acceptable levels.

THANKS MAN..I love being able to ask questions and get answers so easily. People like you make these forums as good as gold for everyone of lesser knowledge. But who are trying to learn at least.
