Then I fitted them on a larger heatsink after applying some thermal paste: I made two of these that would fit on the ICs: I don't care about 1117 regulator (although this one heats too). I only intend to cool RTL2832U and R820T. I needed two pieces of aluminium (or other thermal conductive material) that would "connect" the two ICs to a larger heatsink. ![]() Obviously, it couldn't do much (I couldn't keep my finger tip on the solder blob after 15 minutes of powering up the dongle). My first idea was to drop some solder on the thermal pads below the tuner and demodulator.
