I just finished several hours of intensely working out HP’s new Elitebook 8440p, Elitebook 8440w and Elitebook 8540w models this week running several games in a row (special thanks to several friends who helped). Well, to be frank, we weren’t just ‘officially’ testing them – we had lots of fun playing the latest game titles and creating fancy CAD car models while at it!
I’m not gonna post a whole bunch of benchmark and temperature numbers here, perhaps at a later point in time, but today, I want to keep things simple and straightforward. The HP Elitebook 8440 and 8540 models have very much improved heat control compared to previous models. So far, I’m not sure what’s bringing such a huge improvement – better fan speed control, reshuffled component layout or more efficient components – but there was a tangible difference I could feel. After about 8 hours of running a mix of AutoCAD, 3Ds Max, Left4Dead 2 and Need for Speed Shift, I could literally hold the quad core Elitebook 8440w and 8540w models using my bare hands, by the bottom of the notebook, without getting my fingers and hands fried. The dual-core Core i5 running Elitebook 8440p fared much better: after going through the same stress test, it really didn’t feel as if the notebook had been doing any work at all – it was as cool as a notebook that had merely been idling with some windows open.
For comparison’s sake, I wouldn’t touch the bottom of any old generation Elitebook that I knew had just undergone some heavy task lifting because they can literally burn!
Off topic: Anyone know why notebooks can suddenly ‘switch off’ and how to solve this problem? There was an Elitebook 8730w (among other various notebooks) at the gathering which frequently (and suddenly) switch off without warning. I suspect it’s due to overheating (processor can go up to 90-100 degrees Celcius running the same apps/games as above) though I’ve tried cleaning the fan and even removing the bottom panel for better airflow – but no luck.
