Hello, all:
I have an old Toshiba 15.6" laptop with an intel core i7-2760QM CPU (4 core / 8 thread) that I have re-purposed. I run the World Community Grid cancer gene mapping project on it, 24/7/365 (using BOINC client). Typical CPU temps are 55° - 65°C roughly 2/3 of the time, with routine spikes to 75°C, but never higher. It's been running this way for several months. (I use HW Monitor to monitor & log temps). Windows 10 Home (x64), v. 1709, latest updates/patches.
Before I started this project I blew out all the dust (esp. out of the fan exhaust vanes), and using 91% isopropyl I cleaned the CPU top and the copper heat sink face, then re-pasted the CPU with Arctic Silver 5 ("long bead" method, down the long side of the i7 die). I also lightly "tinned" the copper face of the sink. I also have the laptop sitting on a Cooler Master laptop cooling pad, w/ 200mm fan. It's powered by a USB plug on my Cyberpower UPS (1000W), so the laptop /brick isn't power-stressed.
Using the Windows 10 "Power Plan", I tweaked the min. / max Processor power down from 100% down to 99%, so Turbo Boost and SpeedStep are deactivated. All four CPU cores stay at stock 2.4GHz speed.
Never has any lockups or BSODs.
My question is: are these temps w/spikes okay? Are these spikes going to shorten the life of the CPU / peripheral components?
Thanks in advance!
