What is the ideal cpu temperature?

Is that at idle or under partial or full load?

It's probably too hot in any scenario unless your ambient temperature is really high.

manchan,

Since there are 101 variables, it's important to be specific.

What is your ambient?
What cooler are you using?
Are your fans at 100% RPM?
What utility are you using to test Load?
What utility are you using to measure temperatures?
Are you referring to CPU temperature or Core temperatures?

From my Core 2 Quad and Duo Temperature Guide: http://www.tomshardware.com/forum/221745-29-core-quad-t...

"... Section 6: Scale ...

...Scale 2: Quad
Q9x50: Tcase Max 71c, Stepping C1, TDP 95W, Idle 16W
Q9300: Tcase Max 71c, Stepping M1, TDP 95W, Idle 16W
Q6x00: Tcase Max 71c, Stepping G0, TDP 95W, Idle 16W

-Tcase/Tjunction-
--70--/--75--75--75--75-- Hot
--65--/--70--70--70--70-- Warm
--60--/--65--65--65--65-- Safe
--25--/--30--30--30--30-- Cool ..."

Tcase = CPU temperature
Tjunction = Core temperatures

Comp  

ideal temp is the highest temp that the system will last at for the longest amount of time or the full life of the system
this would like chart with hours used per day vs cpu output

bottom line is 55-65c for quad core, each core at 100% should give you 7 year life

remember if the individual cores read 55-60c the temp of the cpu might be 49-50c
you need core temp

It depends largely on the person running the system. I personally don't want to see mine rise much higher then 45c. Others won't start to worry until is passes 80.

I read something somewhere that said the average chip lasts four years at 40c constant. Since you will be idling much lower then that (hopefully) a good cpu should last about twice as long as that.

Of course all these numbers are bull$hit as I have yet to hear of a person having a processor "die" on them after 2 or more years of operation.

My ambient is anywhere between 77-80 degrees F
I'm using the stock cooler.
Yes my fans are at 100%
I checked my temp through the bios where it read 70c and on coretemp 60c
By the way my Quad is a G0 stepping

Your ambient is 25c to 27c.
As uguv has already asked, are you temperatures at Idle or Load?

70c in BIOS, which is CPU temperature, is far too hot. Also, Core Temp reads 5c too high on 65 nanometer G0 processors. Use Real Temp 2.7.

^^ Use realtemp and post scores here, but so far it sounds like you need a better cooler.

My temps are at idle.
in Real Temp my core temps are 53,53,50,50.
My distance to TJ Max are 42,42,46,46
Min. temps are 52,52,49,50
Max temps are 63,64,61,58

Your stock cooler is most likely not properly seated. Firmly press on each corner one at a time for about 30 seconds while you watch Real Temp. If you see any significant drop, it confirms that a push pin isn't anchored.

idel temp is 98.6f that why you can smuggle throw the air port with out the body scanner seeing it run?

idle temp is the lowest temp

idel temp is the temp where the cpu last as long as you want it

there are soom good charts that show voltage vs life / per daily usage

a 24 hour server needs low temp and low voltage if google wants 7 year out of it. then again a gamer that only runs the cpu max a few hour day can get 70c for nice oc

After i reseated my cooler my temps are now
41,42,35,39
tj max 54,54,60,67
Min temp 41,41,35,38
Max temp 45,45,41,42

Thanks for all your help

thats better, it a common problem and in my opinion an issues wiht the LGA 775 platform, when coolers use push pins. it is on some motherboards way to hard to get them on and you fell like you are damaging your MB. the only real way to know for sure it on, is to hear each push pin click, and check with eye, to see if each ahs latched.

Yes I agree 100% dobby.

I've recently installed a Thermaltake Liquid cooling system. I have an Antec box (180); Dual core Pentium D 3.2GHZ; ASUS P5WD2-E Premium MB; 2 X 2GB Kensington DDR2 PC-800MHZ RAM; and a ATI Radeon HD3870 Video card. My AIBOOSTER says I'm at 1.39 Volts; my CPU utilization fluctuates between 30-46% and my CPU temperature is at 66 degrees celcius!!! My system temperature is at 36 degrees which is ok I guess. Question is, I'm not running anything except for Outlook, Messenger and Google Chrome, so why am I running so damn hot?

My cooling is running nice and fluid, the connections are fine (as far as I can tell, my reservoir is far from empty, and I can't get the damn CPU temperature down.

Does anybody have any ideas to lower my CPU temp, or is this normal?

I intend on using my PC for 3D apps such as 3DS, Rhino, Pixform Pro and SU, however I'm quite worried about stability given the characteristics above.

Thanks for your help in advance.

I had a Pentium D 3.2 Ghz, just like you have and it's idle temp was no less then 65ºC. I belive it's a defection that happens with all "Pentium D"s, as my new Core i7 doesnt go far fom 45ºC even on full load.

I would suggest you to get a new CPU as the pentium D runs very hot and isnt so good. If your budget is low then just buy a Core 2 Duo, even if it has a lower clock then yours, becouse the performance is better and runs quite cooler.

Of course this is just a suggestion. If you cannot afford a spontaneous cpu upgrade (wich is quite normal) then I suggest you don't worry, becouse my Pentium D is still alive (after 3 years) even on such high temperatures. There's nothing you can actually do about it (I tried lots of things, including new coolers and all, with no luck).

Good luck.

Last August while building a pc for myself I replaced push pins for the cpu, northbridge, southbridge, and mofset heatsinks on an ASUS motherboard with #40-4 nylon nuts and bolts that I bought at Ace Hardware for 11 cents each. The idea was to make sure there was even pressure for good contact. I also replaced the thermal compound pads with a good quality thermal paste. It worked like a charm. CPU and core temps dropped as intended.

The mofset heatsink was the worst problem. When I removed it and looked at the thermal pad I could clearly see that contact was uneven. The thermal pads on the northbridge and southbridge chipsets also indicated uneven contact but to a lesser extent. The same thing can happen when cpu heatsinks are not installed properly.

I have a p-4 3.06 that ran WCG Boinc for 4 years in my laptop 24/7 , and it is still running year 5 . temps were always in the 70-80c range . guess I got a good chip / motherboard . A lot of those dell 5160 laptops melted .

I had a similar problem and it ended up being that (pardon me if my language isn't correct) the heatsink went bad. By heatsink I mean the actual connection between the cpu fan and the cpu. As I learned the cpu can doesn't cool the cpu. It draws the heat from the cpu and if you have a bad connection then it won't draw enough heat
