This is the continuity of my previous posts My Modem Gone Up in Smoke! and Inside My Linux DLink G-604T Broadband Modem/Router. Seems my local vendor finally replaced my faulty G-640T after eight month use with a new broadband wifi/router with same capabilities albeit different model (G-2640T). The new model is smaller, has shorter antenna and generate more heat than its predecessor.
I hate going back and forth from computer shop and my house to claim warranty, I prefer to have a fully working hardware that I can truly rely on. Thus acting on advice from my blog readers (especially Azmeen and Kucau I decided to improve the air ventilation for my broadband modem.
Because I dont have an air conditioner, I have to improvise in order to keep my modem cool and ventilated, I removed the outer casings of the modem and attached an ordinary 12volt casing fan on top of it with a strong glue. I powered the fan with a general purpose low voltage AC/DC adaptor (‘walkman’ adaptor) to make sure the modem stays cool during operation.
Without fan, the modem capacitors heat up so fast (approx 30 minutes) that it could burn up my fingers. The attached casing fan dissipate heat quickly resulting the modem circuits felt as cold as water.
Here’s a link to my other sloppy DIY work :p
