Re: Gecko G201 heat sink question

Hi,

Steel is a miserable heat conductor. Even if you used aluminum, a
plate is a very poor heatsink. The heat would have to travel
laterally thru what is a very thin cross section. Be thinking instead
of a heatsink section 4" by 6" with fins at least 1" deep. If a fan
is used, the sink can be smaller. Also use thermal grease, (the white
gunk) between the drive and heatsink.
