Test Setup[COLOR=#222222][FONT=Tahoma]To test this device it is quite simple. We will use my Sony Vaio VGN-NW21ZF laptop, which is a Intel 2.13 GHz dual core CPU with 4GB DDR2 RAM and plenty of other leading features. It is a laptop that is fairly prone to producing lots of heat but has in-built technology to throttle back the cpu when idle to reduce this. So to test this Laptop Cooler we will need to keep the CPU running at full speed – enter Prime95.
(This is not a picture of my laptop/model)
We will turn the laptop on and run Prime95 using a torture test for 20 minutes, the first time on a wooden desk and the second time using the Akasa Helix. We will monitor temperatures and record the final results of the motherboard and CPU cores. We will also record the starting values for these and as such measure the temperature difference from start to finish. This test will be repeated 5 times minimum to give the most accurate results.[/FONT][/COLOR]
Is not that quiet at pros?Cooling laptop stands aren't efficient whith laptops with small amount of venting holes at the bottom of notebook. And also there is problem with distortion of air flow under laptop. (hope i wrote it clear – my english isn't good). It's better to rise laptop by placing something under. and after warranty if you don't care about look of laptop case, removing few parts of grill on intake and output can make big difference (changing thermal compound and modding laptop case gave me ~5*C delta at stress.Regards :)HeXeN
Whoops! That one slipped through the net! Cheers.Yeh, they never will be very good, in my view they are pretty pointless. I added a larger 6-cell battery to my laptop and that raised my laptop up to a nice level and has improved the cooling quite dramatically (as well as improving battery life to 4+ hours)Simon
Great! Movie i love it!
