processor + hard drive heat allowance - intel t5300 and fujitsu mhv2120bh pl

I have a HP dv6000t with an intel t5300 core 2 duo processor and fujitsu mhv2120bh pl 120GB hard drive.

I recently decided to put Folding@Home on my laptop, but I was concerned with the heat. According to HWMonitor and Speedfan, each core is running at about 75C when I have one instance of F@H running (ie, about 50% processor utilization because it will only run on one core) and at about 80C with two instances running. They run at about 60C without much load.

I looked at http://processorfinder.intel.com/details.aspx?sSpec=SL9WE. Would this indicate that I'm safe as long as I'm under 100C? Or does it mean that they'll surely fail at 100C, but I should probably still avoid running F@H?

The hard drive just runs hot in general. I've seen posted that my hard drive is only supposed to go up to 55C, but it is commonly in the low 50s and often will go in the 55-60c range.

How problematic is this? Should I invest in a cooling pad or something? Is it safe to just use a spray bottle of compressed air to clean out the fan?

Thanks

 

You are on the warm side of comfortable. I wonder if the general heat is causing the hard disk to warm up. HDD temperatures depend a lot on notebook design.

Perhaps you should look into undervolting the CPU. See the undervolting guide. It should not be difficult to take a few degrees off the temperatures.

undervolt your T5300, it will run 100% stable with all of the multipliers running at 0.950V
That should help cut a substantial amount of heat from your CPU.

I also run folding at home on my T5300, and the cpu never breaks 55C, cause I have a dell and I have the i8kfangui software always running the fans at full speed.
Unfortunately that sofware will not work on your fujitsu, but if you are concerned about temperatures, you should get a good notebook cooler. Running the laptop always at high temperatures like those are not good for it, and can cause premature failure, so check out undervolting and maybe get a laptop cooler, and you will notice a substantial drop in temperatures.

That's true

Undervolting is your best friend. You could also try Artic Silver 5. My C2D t2500 undervolted + C2D has a max temperature of 65c under load.

 

Heat is a bigger issue with notebooks than desktops. Not in production as desktops produce more but with the ability to dissipate. I would not recommend "folding" on a notebook. I did it on mine for a while. And sad to say no reason to add that stress to a notebook. Sorry.

 

Thanks for the advice. I'll go about undervolting now, even if I probably won't end up running Folding to preserve the function of my laptop for as long as possible.

 

I have now undervolted it. Stress test went over fine, and now everything is at .950. The rest temperature didn't change much (I assume this is because the fan only kicks in at a certain temperature, so I'll be stuck with low 60s), but now the temperature stays in high 70s under max stress for any period of time.

One thing, though... The temperatures I'm giving are listed in HWMonitor as inter mobile core 2 due core 0 and core 1 temperatures. There's also an ACPI THR1 temperature that's consistently about 15 degrees below the listed core temperatures. The temperature that RMClock lists for cpu core temperature is typically close to the ACPI temperature. In other words, it's saying the cores are about 15C cooler than HWMonitor says the cores are. NHC's temperatures are similar to RMClock's (though I'm not running it now because I heard there were conflicts between NHC and RMClock).

I assume this is a fault on RMClock - claiming that the acpi temperature is the core temperature?

Thanks again for the help, everyone.
