results of my M4600 burn torture test :)

ok so i figured it was time to clean the dust out of my M4600 and swap the stock paste for a dollop of arctic cooling MX-3, so after waiting for 24 hours to make sure the paste was nicely settled i ran a 4 hour torture test on my M4600 to see what kind of temps i would get.

i ran prime 95 to get my core i7-2620M up to 100% usage, and I ran FurMark to get my Firepro 5959 up to 100% usage.

for the first half an hour the fans were still on low, and the temps were climbing slowly through 60*c. I checked again after 4 hours and the temps had stabilized at 75*c for the processor and roughly the same for the Firepro. Fan was kicking up to high, dropping back to low after a while, then kicking up again. Hard drive was reading temps in the 45*c range.

at idle, the processor idles in the 45*c range, and the firepro a few degrees higher (around 48*c)

during the torture test, the keyboard and most of the laptop remained cool, but the vents above the RAM slot was hot, and the back of the laptop was hot. i suppose if you have a quadcore processor with ram below the keyboard, the keyboard will be hot on those models.

overall i am very pleased, my m4400 and previous laptops used to get up to the 80s and 90s when under full load so mid 70's for full load is relatively cool, especially for the high ambient temperature here in Singapore (30*c)

hope this helps

 

just a picture highlighting the areas that become hot when under load. everywhere else is cool to the touch

its strange how its a "strip" at the back thats hot.
