Intel Core i7-860 thermal paste

Looks ok to me.... but I haven't been checking my BIOS for temps for ages.

SIW shows 31°C for my CPUTIN (Max 33°C), SYSTIN is at 46°C

Core Temp shows:

Core #0: 42°C
Core #1: 39°C
Core #2: 40°C
Core #3: 38°C

Running between 1-6% load

 

I see the following Core Temperatures:

#1: 43°C
#2: 41°C
#3: 43°C
#4: 39°C

Maybe I was editing my post by adding "To which temperature should I set the CPU Warning Temperature?" while you were responding. I have initially set it to 60°C. Is that reasonable?

 

After installing Windows XP SP3:

System Temperature is 36°C idling.
CPU Temperature is 38°C idling.
CPU Fan Speed is 1570-1580 rpm idling.

Core Temperatures idling:
#1: 38°C
#2: 36°C
#3: 39°C
#4: 35°C

It seems like the thermal pads have started "melting" into shape.

 

Rockster,
it is a build for someone else and I'm preparing my defence speach ... ... but so far, no mushroom cloud!

I do want to learn about new things, especially when I'm in a total mist. The hardware for this build is all new to me and the intended operating system (Windows 7) too. Initially, I install Windows XP to partition and format all hard disks prior to installing Windows 7. The reason for that is to make it possible to use Ghost 2003 booted from floppies. (It has something to do with formating and "sector alignment" that XP does differently than 7 but I haven't finished researching the topic. Maybe I won't since just knowing the basics might be enough.)

Using the stock cooler is NOT out of character ... ... because I've never used anything else. All previous builds have been "medium" and this is the first "higher" end that I do. The consideration is new to me and my conclusion is to stick with the stock cooler, monitor temps and if it seems to do alright, it stays. It has somewhat to do with cost but if I should decide to recommend the owner to invest in a better cooler, he would do so.

About the Koenigsegg CCX, I can research that question too since the cars are built some 100 km away from where I live. I've never been there but it's not too late. I think you can derive my answer from this scenario: Our gliding club bought a new Self Launching Glider, an ASK 21 Mi. It has a rotary engine (Wankel) and it can be run on regular automotive fuel and AVGAS 100LL (aviation gasoline 100 octane low lead) . We run ours on AVGAS 100LL, simply because the manufacturing process and thus the quality of the fuel must adhere to strict regulations. Automotive fuel can be "anything that burns ". So, my answer is that if it were allowed (which it is not due to a difference in taxes) to run a CCX on AVGAS 100LL, I would do just that and I'm sure Koenigsegg would actually recommend it. With adjustments, there would probably be a performance gain.

 

Bill,
I'm aware of the limitations of temp checks in the BIOS but with nothing installed ... ... there are no other options and those readings are better than nothing for an initial check. I actually think it would be stupid to omit that initial check. It takes fifteen minutes idling (you and the computer) and it's free.

 

Bill,

I wasn't upset and will edit the smiley from ... ... to ... ... ! You're right that a good utility (no one named, no one forgotten) should be used but I'm not there yet. If someone who is about to embark on his/her first build reads this, I wanted to emphasize that the temperature readings in the BIOS are available and should be used.

A thorough reading of the BIOS manual is also a good precaution, especially if it is the first build.

 

Yes, that's what I meant, I misspelt "motherboard" ... ... !

 

Any suggestions?

The options are: Disabled - 60°C/140°F - 70°C/158°F - 80°C/176°F - 90°C/194°F

 

Thermal Specification for the i7-860 show: 72.7°C

I'd set the alarm at 70°C, but you won't need it, the CPU will reduce speed or cut power if needed.

 

Thanks guys!

I'll download CoreTemp and try it.

I had read the i7-860 specs but was confused by "case temperature ". What case? The Antec P183? I would have used "die temperature ", "chip temperature" or anything but "case temperature ". I'll set the BIOS alarm at 70°C but if the processor is "smart" and "throttles back" if temps get high, then there's no need to worry.

 

Well, the readings certainly differ from SIW but I don't trust that one since it reports strange things for the CPU that even I understand can't be correct.

CoreTemp readings are lower than SIW readings, depending on which core, by 0-10°C (idling). It varies over time and CoreTemp has much shorter integration times.

Edit: I'm wondering (shorter integration times) if the temps actually can vary several °C within a second or two?

 

No, Tcase is the temperature of the the processor case (top center).

The Tjuncton temperature is what is measured by Core Temp. Tc is usually around 15C less than Tj.

Tjunction is the junction temperature between the Die and the PCB it sits on.

 

Of course!
