I’m now going to take a second battery terminal and crimpt it to a Molex.
Now I can plug this into a regular PC power supply and get +12V.
I plugged the two battery terminals together and now the fan spins more than twice as fast as before. And before anyone asks; yes, I reversed the polarity on one of the battery terminals. Not like the fan would spin in the opposite direction if the polarity was reversed. Trust me, I already tried it. The fan doesn’t spin at all.
Unfortunately, the fan is now extremely loud, and since a notebook computer doesn’t normally have any kind of 12V output (Firewire power, but that’s a very low amperage,) portability has gone out the window with this mod. But it’ll be fun to see if my +12V mod help with cooling at all.
After only running for a couple minutes, before I even placed my notebook on top of the cooler, I felt the LapCool4 was very hot itself. I grabbed my trusty thermometer and touched the probe to the fan’s hub.
Wow! 73°C… and CLIMBING!
Let’s fire up Everest again, let her run while I get some lunch, and see if we have any improvement in the CPU temperature.
After only about 15 minutes, the fan started making a horrible noise. I thought that one of the fan blades had broken, but that isn’t the case. The fan is simply too off balance to be able to spin at the high RPM’s created by running with +12V.
Despite being off balance and making a horrible noise, I could tell that the fan was still moving much more air than it was with either the 9V battery or with USB power. I was expecting to see a good two or three degree drop in temperature, but….
OK, let’s break this down….
Does the Vantec LapCool4 LPC-402 cool your notebook? Yes! But it has nothing to do with the fan. It has EVERYTHING to do with the fact that your notebook is elevated enough for cool air to get underneath. So if you can do this with something else, like stuff found around the house, for less money, you might as well pass on the LapCool4.
Is the Vantec LapCool4 LPC-402 portable? Well, it’s smaller than a notebook and very thin. So it is fairly portable as it should be able to slide into your bag next to your notebook.
Is the Vantec LapCool4 LPC-402 good for using a notebook on your lap? My notebook wasn’t a good fit for this. The rubber feet on the front of my notebook was farther apart than the contact surface of the LapCool4. So even though the notebook was VERY stable on a solid surface like a desk, it kept falling off of the LapCool4 when used on my lap, bed, etc.
Needless to say, I am NOT giving the LapCool4 LPC-402 a jonnyGURU Recommended today.
