Motherboard and CPU temp high on a Toshiba

[negue]

Hello all!

I just joined, looking for answers to why my laptop gets so hot lately.

Right now, not having anything else but this forum open on Chrome, RealTemp shows a 64C, with a max of 71 a couple of minutes ago...
Hardware Monitor also tells me the Intel T2310 2 cores have 67C and 69C, and the motherboard (thrm, I guess that's the one) is an impressive 68C. The assembly temp is 42C.

Until a couple of days ago I used to have a 40-45C RealTemp. Now it's up in the 70s for no apparent reason. I haven't changed the way I use my laptop (nothing challenging by the way, usually it's just Chrome opened as I update some sites I manage).

My Toshiba Satellite L40 laptop specs, as provided by Speccy:
-CPU: Intel Pentium T2310 @1.46GHz (67C right now)
-RAM: 1,00 GB Dual-Channel DDR2 @ 266MHz (4-4-4-12)
-MoBo: TOSHIBA Satellite L40 (Socket 478) 66 °C
-Graphics: Plug and Play Monitor (1280x800@60Hz)
Mobile Intel 965 Express Chipset Family
Mobile Intel 965 Express Chipset Family
-HDD: 112GB TOSHIBA MK1237GSX (SATA) 42 °C

Motherboard details:
Manufacturer TOSHIBA
Model Satellite L40 (Socket 478)
Version PSL4CE-006005G3
Chipset Vendor Intel
Chipset Model GL960
Chipset Revision C0
Southbridge Vendor Intel
Southbridge Model 82801HBM (ICH8-ME)
Southbridge Revision B1

I use this laptop plugged-in for 99% of the time, the battery won't last more than 30mins.

What I noticed: temps get higher when Chrome displays webpages that have flash/movie.

Are the temps I mentioned a real reason to worry? Would an external-cooler-stand thingy help keep this temps under control?

Thank you!

A jump like that indicates problems, yes. Blow out all the air passages available with compressed air (can) and see if that helps. You may need to open it up and re-seat the cooling system with new thermal paste. A cooler will help but if you just put it on a hard surface and elevate it slightly in the back with a couple of business cards you can see if it will help much.

Thank you for answering!

Ok, I'll lift the back side a little and see what happens. If not, compressed air it is. Should I blow it from the outside or open the laptop?

If your comforatable opening it, yes that is the best way to clean the dust and other accumilation out. Just Blowing thru a vent hole may help but generally not as effective as opening it up.

Check the HSF fan if not free (turns easily) might as well replace it. Also since it is open, I'd just go ahead and replace the thermal compound. Depending on age it may have lost some of it's effectiveness. Sometimes the dust works itself into the HSF bearings.

If Unsure on dissassembly, you can often find dissasemmbly step-by-step procedures, and or a youtube video by simpley googling.
