Re: Ethernet chip gets raging hot

I keep seeing people talking about touching a chip isn't a precise way of knowing what temps its running at. That is true and I'm sure most people understand that. I've been designing embedded/electronic systems for a long time and know that a good rule of thumb is "if you can't leave your finger o...

Re: Ethernet chip gets raging hot

Judging a chip's safe running temperature by how long it takes to hurt your finger is not the best method at all. The chips are designed to run normally at temperatures like this indefinitely.

Re: Ethernet chip gets raging hot

I can't see anything to help cool off the RJ45 socket/ethernet terminating load resistors :? :?: You don't need to... they are designed to operate normally at these temperatures. I'm having a serious crash problem with my pi (RS) when it gets hot. I "thought" was related to heat (might be?). ... Do...

Re: Ethernet chip gets raging hot

A heatsink system is unnecessary for the Pi... just set your sysctl.conf right and you won't have any problems.

Re: Ethernet chip gets raging hot

It is definitely not a heat-related issue, unless you genuinely have a defective unit. I used a fan to cool the smsc(network/usb) chip in question and I was able to reliably crash the Pi despite the surface of the chip being cool to the touch. I have fixed(for now; I will not rule out a hardware def...

Re: Logitech Wireless Touch Keyboard K400: Does it work for

I am using a Logitech K400 as well, connected to a powered USB hub. The keyboard works fine with no sticky keys or lost touchpad input on a regular(Linux-based) PC, but sticky keys are extremely common on the Raspberry Pi to the point of the keyboard being almost completely unusable. It is so common...
