    Question Max. Temp. of Processor

    I recently bought an Intel Pentium D 940 3.2GHz, 800MHz FSB, 65-nm tech. and was wondering what is the maximum temperature I should allow it to reach once I begin overclocking. I haven't been able to find a specific temperature, but I think 60 Celsius is as high as I feel comfortable with.
    The rest of my system includes an Abit AW8D mobo (Intel 975X Chipset), 1Gig of PC2-6400 OCZ RAM (obviously running Dual Channel), and a XFX GeForce 7900 GT 256MB Video Card.

    Typically Intel processors can run at a maximum of around 65-70C. I would suggest doing your best to keep it below 60C when both cores are at full load.

    thanks avid. I think i'll aim for a 55C maximum to be on the safe side

    Since this is already here I won't start another thread. My X2 is running at 2.4GHz (1.4v) and with both cores at 100% usage 24/7 my CPU temp is 54C with a room temp of 72F. This should be cool right? I'm amazed at how much my temps rose from the VC and CPU upgrade. My mobo temp went from 30C to 40C! I've been contemplating taking the dremmel to my beloved case and cutting a top exhaust fan, and/or maybe switching my rear Panaflo back to 12v...

    Aup I have the 950 running on 975x chipset Asus board you may be intrested in checking out my overclock got a screen shot on my website here.

    My Website - Overclocking Pic and other pics of computer

    As said by Avid6eek your ok with Intel procs upto about 65-70 but to be on the safe side dont stray above 60 whilst running 2 instances of prime 95.

    I have found that I was unable to get above 60 anyways as it would fail on Prime 95 just as I was getting 60 I think it is the RAM holding me back now as it is the high RAM useage instance of Prime 95 that it fails on each time.

    I have already relaxed my latancy timings as much as I am prepared to in order to get a better overclock so unless I am prepared to get better RAM I have reached my limit.

    If I wanted to go any further I would also want water cooling too anyways wich I am not keen on the idea of, I know it is safe if you maintain it well but water and electics just seem a bad idea to me.

    BTW

    If you havent already get an aftermarket CPU cooler as the Intel ones suck, so everybody says. I never did even try the stock cooler aftermarket ones are cheap enough and make for a much better overclock.

    Pentium 4 will throttle itself to slower clockspeed once it reached temperature above 74 degrees celcius. Thus, it is adviseable to keep your CPU temperature below those threshold..........

    Keeping your CPU cool by the means of cleaning off dust, repositioning fans for better airflow, etc - not only increase the overclockability of the CPU, but lower down the CPU HSF fan speed and noise. Nobody wanted to hear high-pitch sound of the fan spinning all the time.

    And due to the 65nm process - your P4 will be cooler than the old P4's. And remember to STRESS both cores while doing the stability test.....

    Yeah them video cards are well knowen to run rather hot wich will cause everything to get rather warm plus I would think swiching from single to dual core has gotta make a considerable difference too.

    As for the video card temp I found getting this PCI exhuast fan made loads of difference if you have a spare PCI slot to put it in.

    Better link for specs

    I know I know it looks real tacky and you would not expect it to do anything, well it did seem to make quite a difference for 3.00. I only bought it expecting it to help the video card a tiny bit but it helped everything cool down a little and I managed to get another 0.14ghz out of my cpu overclock. (From 4.30ghz to 4.44ghz)

    I suppose helping get rid of the hot air from around the video card helped it keep sucking in new cool air rather than used warm air, even though the case already has 120mm fan front and rear and a 90mm on the side panel.

    I carnt remember the exact temp difference but I was very supprised.

    In a little while I'm going to switch my Panaflo to 12v. Should give me a lot more airflow.

    For cooling I'm using a Golden Orb 2. It's a huge chunk of copper (752g) that I almost decided not to attach to my board because of the weight. I've increased my 940 to about 3.7GHz from 3.2GHz and under full load the temp is about 37C-39C. I think I'm going to try for 4.0 and if I can make it and not have any temps get to high and still maintain stability I'm going to stop there. When I first booted my system my board down graded my RAM from 800MHz to 533Mhz, and claimed it didn't support 50 Ohm ODT. I looked on the Abit forums and someone else had the same problem and was told that raising the core voltage to the recommended 2.1 volts and returning the timings to what they should be would fix it. Anyone know a way to test whether it actually running at 800MHz? 3DMark06 says they are running at 0.

    It will say it the BIOS what speed it is running at.

    That 940 OCs the same as the 950 BTW I only got the 950 cos I got really good deal on it.

    So depending on just how good that CPU cooler is you should be able to get as high as 4.5Ghz which I have done in the past but it is not stable enough to run all day everyday for me so I have backed off to 4.4Ghz.

    But just take it slow and be sure to stress test both cores when you do not just one, if you havent already you will need to raise voltages to get it stable though at above 4.0Ghz.

    My CPU voltage is on 1.40 and my Memory voltage is 1.90 for some reason it wont let me raise the voltage for the RAM anymore or it goes unstable.

    As it is my RAM holding me back that has ratherhacked me off it should be able to take more than that. I am tempted to get some more and go for the 800Mhz ones this time instead of the 677Mhz and the platinums instead of Gold.

    i had my 940 at 4.0 GHz, but was unstable. I tried voltages up to 1.475, but that didn't help. I've turned it down to 3.9 and it's perfectly fine. any suggestions on getting it to be more stable? My ABIT uGuru showed temps of about 48C under load (rebooted after only about 5 min of load)

    Noway I was expecting you to get better results than me as you have faster a smaller modules of RAM which should mean for better overclocking.

    I can get 4.2Ghz stable at 1.40v and 4.4Ghz stable at 1.45v.

    I am supprised, temps are well within what they should be for you, mine is 55c at 4.2Ghz full load and 58-59c at 4.4Ghz full load.

    I really dont see why your having troubles, what stepping is your 930?

    Also what voltages, frequency and latancy timings have you got on your RAM?

    My Asus board auto adjusts my RAM for a better OC when I raise the FSB so if yours is not that maybe the problem.
