Raspberry Pi 4 Model B Aluminum Case RPI 4 Metal Shell Black Box for RPI 4B (Without fan)

This is to be used with a RPi4 running Freeswitch PBX software which is a medium processor intensive program. Thus keeping CPU temperature down is important for reliability. This fan does that. One point I did have trouble with is the included self-adhesive heatt conductive pads. These are quite thin (good) but the peel off strips protecting the adhesive are difficult to separate and I did tear one of the pads in the process. However sufficient pad was saved to stick to the appropriate chip case. I will probably buy this again.

Really good thermals... only bad thing is the silent fans have started making noise!

Would have given this 5 stars if I could attach the fans but unfortunately the supplied screws are too small and no screws in my toolbox have the correct thread - disappointing. Not sure if this is manufacturing defect. I've had to settle with double-sided sticky tape for the time being
