Thermaltake T1000 Laptop cooler

I was unsure as to how to obtain a fair result between testing the cooler on my lap and just the laptop on my lap, as I had no way of making the laptop fan consistent and it has a tendency to stick to fully on at random times even when it has cooled the CPU right down. So my testing is just based on subjective observations I made while using it (I tried to be as fair as possible in my comparisons). So sorry to everyone that wanted a pretty graph to quickly judge performance by.
While I worked with my laptop I left open several monitoring applications, coretemp and speedfan were the most important, and kept an eye on the reported temperatures of the components of my laptop. I used the laptop with the cooler both with the fan on and off, and then again with it just on my lap without the cooler at all. This is what I found out...
My laptop fan stays off till the CPU reaches 58oC according to SpeedFan. It comes on slow and then goes off when it has cooled the CPU down to 49oC. While it is on, it makes a horrible high pitched motor whiney noise, albeit a fairly quiet one. When using the T1000 the CPU fan came on a lot less than without it, and the CPU stayed idling by about 3/4oC less than when the cooler was taken away altogether.
The most noticeable component to be kept cooler was the hard drive. In my room, which was around 25oC warm; under normal use without the cooler the hard drive would rise above 40oC and sometimes be as high as 50oC (after extended periods of laptop use), this is not very good for the hard drive at all. When the cooler and fan were on the hard drive was kept at around 36oC, which is a much better operating temperature for the drive. When the cooler was used without the fan, the hard drive climbed back to around 40oC but the improved airflow from using the cooler as a solid base kept it from going much higher.
After a while using the laptop without the cooler the base of the laptop becomes very warm to touch, without the cooler this becomes too hot to be comfortable and you have to stop using the laptop on your lap. With the cooler blowing onto the base of the laptop it kept the base only slightly warm, and kept the heat separated from your legs because of the thickness of the cooler.
During the use of the cooler I did not notice any additional drain on my laptop and the battery life felt the same as it did under normal use. Windows power meter but the battery drain at a cost of about 10/15 minutes from the 3hours 15 minutes of calculated battery left time at a full charge.
