My HP 635 laptop has bee running BOINC since 2012 24/7. I brought its RAM to a maximum of 8 GB. It had a 320 GB hard disk at 5400 RPM. After trying twp SSD, a 120 GB OCZ and a 250 GB Samsung and they both failed, I installed a 1 TB Seagate hybrid disk at 5400 RPM and so far it runs well. I am running SETI@home,LHC@home and Einstein@home on SuSE Linux 13.2. It used to run also vLHC@home but since the CPU is a AP E-450 AMD which is 32-bit and has no AMD-V enabled in its BIOS, I moved vLHC@home to a 64-bit CPU, A10-6700 and Windows 10. This also runs ATLAS@home and CMS-Dev using Virtual Box.

The question is about running at "full bore", which I take as only using the laptop's own thermal management.
That really is a bit of string - if you are fortunate and the room is very cool, and the laptop has very good intrinsic cooling and thermal management it will last a lot longer than one that is in a very hot room and has very poor intrinsic cooling and thermal management.
Of course you can improve vastly the situation by using a PROPER external cooling pad - one which actually cools the incoming air to below ambient, or a utility like TThrotle.

Yeah the thermal management of the the notebook is really the only issue. My newest notebook, from 2011, can either run the GPU or the CPU at full. Both at once is to much in the summer & in cooler temp it is possible but it does make quite a racket. Recently I've been keeping it by my bed to watch movies mostly. So it hasn't been crunching.
My ancient notebook runs 24/7 only stopping when we have a super long AP outage. With its 1.5GHZ CPU overclocked to 2.37GHz the fan doesn't even run at full speed. 0.o

Could you give examples of this cooling pads which cool down the laptops' incoming air?

Thanks.

A friend played 1 1/2 years daily on his laptop and then he's gone up in smoke.

I thought about to buy a laptop (Intel Core i3-4005U incl. Intel HD Graphics 4400) for 24/7 SETI crunching...
I have no idea if the CPU and iGPU c/w-ould crunch simultaneously 24/7 under full load...

Currently I don't know if it would be a good idea to crunch 24/7 on a laptop.

I build a cooling system for my laptop.

I took the bottom cover off, used the flat cardboard box, it came in and put a fan on the side of it. I made a hole in the box, where the hottest part is and put the laptop on top of it.
After a few adjustments of the spacing and the exact position of it, the laptop runs on full throttle on the cpu, intel-gpu and nvidia graphics card.
The temperature is below 66 Celsius at the hottest sensor (nvidia-gpu).

It is very cheap and works well.
