Baxterzine, where did you connect the fan on the motherboard? There were several suggestions on other threads.
I cut a big rectanuglar hole above the heatsink in my WebPlayer but it still cooks. I really need to add a fan.
I am running WindowsME and have the LinkSys USB network card.
I play mp3s over the network from my desktop PC. I find that the network card cuts out after a few songs because the cpu gets blazing hot. It heats up that whole area of the motherboard where the USB connectors are and then the USB NIC just stops working.
I find that if I leave the top cover off of the unit it plays a lot better because the heat has room to dissipate.
