Hi, I bought an SSD with an enclosure. I have noticed that the SSD gets too hot while using. Now after installing the SSD in the enclosure, there is some clearance between the SSD and the enclosure at the top (approx. 5mm). So I thought that if I could use that clearance by installing some thermal pads on the top of the SSD and then some copper heat sinks on top of the thermal pads. Can someone please tell me if this is a good idea and will it work? I just don’t want to ruin my SSD or the enclosure.

Unless you have some form of airflow to release the heat from inside the enclosure, your plan does nothing but slow the heat buildup process. Unless the enclosure case it metal, for which I would thermal pad directly to it, I would cut some slots for fresh cool air to get in and warm air to escape.
 
If it were my SSD, I would either return it, or forgo the warranty by removing the PCB from the case and add a heatsink to the Phison (?) controller with thermal tape.

Here is an inside view of the 120GB version:

The 120GB SSD is DRAM-less, and the total NAND flash capacity is 128GiB (= 4x 32GiB), which doesn't leave much overprovisioned space for SLC caching. I'm not a gamer, but I'm wondering how this product qualifies as a "gamer SSD".
