Might be a daft question,??? i dont know, but what is an acceptable CPU temperature, typically my duel core processor is running at about 35 deg C, i do use TThrottle to throttle back if it exceeds 35 C, but i`m totally in the dark in knowing what temperature is safe to use without any possible damage to my processor. Just curious ............

best regards,

Tom.

I would recommend you check the manufacturer's specs for your specific cpu model. I can assure you that 35 is generally quite low for almost all devices. Common running temperatures are in the range 45 - 65 deg C, and many (not all) can run reliably up to 90 C.

Generally a component will start to malfunction long before it will be permanently damaged by heat. On the other hand, all the chips in your computer may wear out somewhat sooner if they run very hot -- but in today's world it is hard to wear them out before they become obsolete.

Saying it's dual core doesn't tell us exactly which model or brand it is so nobody in their right mind will tell you for sure if 35C is an appropriate operating temperature. At best all you will get something like rbh said... 35 is probably too low, 65 is probably safe but maybe not. If you want "definitely" rather than "probably" then you need to identify your CPU with a model name/number. Even then, don't expect us to go to the manufacturer's website and do your homework for you. That's your job. We might help you find the data you need but you need to show that you have put some effort into it too.

Hi Guy`s,

not being computer literate i guess i`m not helping, but i found this info in my computer system, if it helps.???.

At the moment one core is running at 32 C while the other is around 34/35 C

CPU type GenuineIntel
Intel(R) Pentium(R) CPU G2030 @ 3.00GHz [Family 6 Model 58 Stepping 9]
Number of processors 2

not sure this helps or not, and i can only say sorry for not being very computer literate.

best regards,

Tom.

@tom:

According to CPU World Pentium G2030, your CPU is an IvyBridge.

TDP of 55W don't generate much heat. 30-65c is fine.

Found it yourself too? There ya go. Now you're more computer literate than you were a few hours ago :) It doesn't happen overnight for anybody, it takes time. Keep up the good work.

It seems my I5 runs at close to 100C temperatures.

Probably because of Intel's famous heat-sinks..

That is the reason why I never use original heat-sink.

Intel's heat sinks have always worked fine for me. Your problem could be due to poor case airflow design and failure to evacuate the heat from the case with the result that you're trying to cool a hot CPU by blowing hot air at it. That never works very well.

Right now my CPU temp is 46C and my GTX 670 temp is 47C. The fans are running so slow I can barely hear them. That's not a typo, 46C on the CPU and 47C on the GPU. Stock heatsink and fan on the GPU, running full bore crunching a GPUgrid task.

The original heat-sink is good for common work, but after overclocking and with high load, the temperatures go to 70 °C or more.

Mine go to 50C when OC'd and at maximum load. Yes, 50C, no typo, just air cooling, not water cooling. Ne kecy.

it must be an airflow issue. I took my laptop outside and it dropped from 96 to 70 Celsius. It's -9 outside. Don't feel confident enough to open up the laptop though.

The CPU should protect itself from overheating since like Pentium 4.

Have you tried vacuuming the vents?
I notice you are using Linux, is there a power management option somewhere? If so, is there an option to select a more appropriate power consumption setting?

Ahh, laptop. I assumed you were talking desktop. It turns out we're both right. To conserve space they often use a small heatsink as well as small fans to conserve space and battery power. Airflow is not great either with so many components jammed into such a small space. Laptops are simply not designed for constant, heavy duty computing and it won't last long if you continue to use it that way.

You can improve the cooling considerably by adding external fans that blow air directly into the fan intakes. The problem with that is to do it properly you often have to build the device yourself. It consists of a platform for the laptop to sit on. The platform has additional fans on its bottom side that blow into the laptop intakes. I built one for a laptop I used to own and it worked very well. I searched stores for one but none of the models I found had fans situated exactly where they need to be. They simply blow air at the bottom of the laptop which I suppose improves things a little but the setup I built is far superior. You might find one designed specifically for your laptop with fans located precisely where needed but it will likely be very expensive. You can build one yourself for about $20 or even less if you happen to have spare parts laying around (fans and a wall-wart type power supply).

An alternative is to add fans that suck air out of the exhaust rather than push into the intakes. Whatever is easiest and works.

The other thing you can do is install and use TThrottle which simply slows the processor down so it produces less heat. Tasks then take longer to complete but if you are intent on crunching with that laptop you might not have any choice.

Hi Swiftmallard and Dagorath,

I've already tried the vacuume cleaner, I don't think it's dust.

I might get a cooling pad to place underneath.

At the moment I'm using a handy throttle program that works well with linux mint. I simply set it to a lower GHz at night so the temperature is stable around 70C. During the day I let it run full throttle at 95 - 97C, it's hot, but it's stable and the chip has built in protection should it reach 100C.

Suit yourself but it will be dead soon if you continue to run it that hot.

Well, since i started this thread, and now having read all the replies with regard to the temps you guy`s are operating at, i can see my original post, about worries of my CPU running at just 35 deg C or so, was totally unfounded,LOL.

regards,

Tom.

Have you adjusted Boinc so it only checkpoints once every 15 minutes instead of every 60 seconds? If not your hard drive will die sooner then it should. Laptop drives ARE much better then they used to be, but still aren't designed to be run hard and hung up wet. Extending the time to checkpoint to 900 seconds, 15 minutes, on a stable laptop means a longer life of the drive, especially the SSD drives.

And get that underneath cooler ASAP if you value your laptop!! And a good backup program too, there are both free ones and pay ones, but get one and USE IT!!
