CPU cooler on laser diode

So, lately I've been thinking about using my useless Intel stock cooler to cool a laser diode, something like a PLTB450B at 1.25A. My plan is to flatten the diode module on one side, and use thermal adhesive between the flattened side and the cooler. Would this be a good idea? And considering that the heat output of the laser diode would be over 10x lower than the TDP of a low-end CPU, would not turning on the fan allow for a good duty cycle?

There are better clamp heat sinks that could be used to couple heat into your CPU heat sink. Using a copper module clamped this way would work much better.

If I may ask, where can you get these?
Just a thought... you could use a lab style host. I did something similar with that diode recently.

Thanks for the suggestion, however I'm specifically looking to use my crappy Intel stock cooler for something.

Available on eBay, among other places.


You can also find them with lugs sticking out of of the sides for top-down mounting. Often easier than screwing things on from the bottom.

Or you could just use thermal epoxy.

There is one that clamps around the AixiZ module with a single screw at the top and clamps using two screws at the base, made of aluminum, but I haven't found one in my search on eBay yet. It is better for transferring heat from the module because it doesn't use a set screw and the base has a couple of flanges that the screws go into to secure it at the base.
