PCIe Diode temperature - any physical solution?

@chrishees - Well… This gets tricky! While I agree this chip should have a sink as even my 2013 Trashcan gets too hot!

So how? I know some folks slapped on an off the shelf sink. But this only goes so far!

Once the heat sink gets saturated with heat it needs time for the heat to dissipate into the air stream and that’s the rub here! The air flow down at the base is mostly drafted to the systems heat sink, this area gets very little flow!

So one needs to get the heat higher into the chimney area without touching the systems sink or anything else. I ended up making my own sink using some thick copper for the base and copper rods mounted to this base about 3.5” long so the rods are able to shed the heat deeper in the air flow. I drilled and taped the holes and threaded the rods into the block with thermal paste in the threads and used a heat transfer double stick tape to hold the block on with a few drops of epoxy just a small dot on each side just to be sure the block didn’t shift

Now to be clear, I was a heavy graphics user when I was shooting and my data is not on the systems SSD drive I use a M.2 RAID setup via Thunderbolt so the PCI interface is running hard.

My solution is quite extreme and I fix Mac’s so I have the tools and skill to do this. I also use TG Pro to monitor things as well! Or stick with the off the shelf solution.

So consider your use and maybe getting an A/C system to cool your place maybe the better answer. Pumping cool air into the vent area might get you over heat of the day.
