Cooling the SmarTEE from NooElec Empty

After reading a number of posts about improving radio noise by cooling your SDR I decided to try the same on a NooElec SmarTee SDR that I use with Linux. I noticed previously that this SDR runs hot but was assured that this was normal ....

So I fire up Gqrx and look at the spectrum display on 137.5 MHz. I then bolt on to the SDR body a pair of heat sinks reclaimed from old PC graphics cards. By chance their mounting holes line up so it really was just a couple of small think bolts with nuts.

Over the next 15 minutes I see improvements in the noise floor but no change to the peaks. So for now the heat sinks stay on. Every little helps - right ?

I thought about doing this. I've got some old CPU heatsinks lying around. Cut two pieces to fit two sides of the dongle and attach with some heatsink compound and I think it would certainly help. Now I have to dive though the bins in the basement.
