Heat, Fans and Wireless

I have a T41 2373-1HU with 768Mb of Ram, and I upgraded the hard drive to the 60Gb 7200-rpm drive. I have posted before that this machine runs cool and fast. I never seemed to have the fan issue that has drawn so much attention.

This machine has (had) the Intel 2100 Wireless NIC that did not work reliably. I normally kept it disable. I ordered the IBM 11 a/b/g card and replaced it last night. Also last night I update the Embedded Controller to 3.03. Separately from the machine, I installed a Netopia Wireless Router (3387W-ENT).

Tonight I have it all working with the Netopia "Closed" (Scanners like Netstumbler can't see it - I tried) and with WEP on and working.

After quite a bit of work on wireless including moving data wireless between laptop and desktop, I noticed the fan was running fast blowing hot air. The bottom of the laptop was a bit warmer than normal.

It occurs to me that the active wireless NIC may be using power and generating heat. I plugged in my LAN connection and disabled the wireless without shutting down or resetting the laptop. Within a few minutes, the fan returned to low speed (noticeably quieter) and the laptop appears to be cooling off.

Is is a valid conclusion that an active wireless NIC would generate this kind of heat? ... JDHurst

Most definatley those little suckers get pretty warm.
Run it for a while then put your wrist on the underside of the palmrest directly under the trackpad in fact sometimes deending on the ambient temp. of your surroundings the trackpad itself can get quite warm.

NIC Cards are radio transmitters and receivers. They are definately prone to expelling a lot of hot air (like my ex!)

That was a great comment matt....

made me chuckle for a bit there... just one thing, I think that you forgot about the ex-in-laws (you didn't say if you were married or not but I took a guess).
