A lightweight, low profile “temporary” (less than 2 hours) solution.
Having been an owner of a Dell Inspiron 5160 (2GHz Prescott), the term “heat-generator” comes into play. I recently upgraded to a HP Compaq nx9420 17” Dual Core 2 notebook due to the intensive applications I have been more involved in as of late. The Dell could not keep up and the heat generation was getting unbearable. When I first purchased the Dell about three years ago, I came across a new lap pad by Laplogxx (L/L). Very costly but it made working with the Dell amazingly comfortable. Since upgrading the notebook, I have done extensive research on any “newer/improved” passive lap pads. I came across the Lapinator Plus! (L/P), reviewed their claims, research and the reviews so…I made the purchase.
Having received the Lapinator Plus! in short order, I immediately put it to work with the new HP. Within 2 hours of non-intensive work with the HP, I began to feel some heat at my thighs and on my fingertips…fingertips? ((105.5 to 102.5 degrees at touch pad and wrist rest (L/P) compared to 90.0 and 92.0 degrees (L/L))
I know I have placed the supplied rubber feet at the appropriate locations and there was nothing running on the notebook in the background to cause the heat I was feeling. I promptly downloaded a couple of temperature monitoring utilities to measure the HPs’ temps. The temps never went over 48 degrees in a 2-hour period with the notebook sitting on a table but when placed on the Lapinator, I was still feeling the heat above and below plus the temps were at or above 58 degrees. To my amazement, I lifted the notebook off the rubber feet and placed my hands on the Lapinator surface, oh my God! I could only hold my hand on the surface ((110.5 (L/P) compared to 93.5 degrees (L/L)) for about two seconds before having to remove it. Plus, the bottom of the notebook was equally as hot ((113.5 (L/P) compared to 93.0 degrees (L/L)). As I let the surface of the pad cool (leaving the notebook raised), I felt the surface of the pad actually had bubbled up the same height as the rubber feet effectively blocking the airflow under the notebook. This was unacceptable even though after about an hour for cool-down it sort of returned to the semi-flat position. At this point I need to take some real measurements (I am a technician by trade and have all the required tools) with my digital probe.
To make a long story short, I measured five critical points (see above) on the Lapinator, the LapLogxx and the HP and found an average difference of 20 degrees between the two, the LapLogxx being the coolest.
One area to point out to the male gender, the BIGGEST difference was the notebook temps at the front by the left speaker and MediaCard ports, with the L/P: 106.5 vs. L/L at 78.0 degrees!
Well, to that end I have promptly requested Lapinator for an immediate refund and RMA to return this pad after only using it for four days and go back to the tried and true L/L. |
