I like stuff to be organized. I found that by organizing my Antminer power supply I lowered my temperatures drastically. And why not give back. This holder bolts between the fan and the chassis. You will have to buy new fan bolts. If I remember correctly I bought a box of 4mx45 bolts to replace the old bolts.
At first I worried PLA couldn't handle the heat but honestly, there has been no problem with heat.
