This may be of use,another topic but the RX18 UNIT cooling was the result. Also elevating the RX18 to allow better air flow has proven to be most effective.

I used a 5 volt laptop fan from Maplins for my RX18, I havn't bothered with any voltage regulation and it has worked fine for almost a year.
As Saxondog suggests I also raised the RX18 and while I had the case off to instal the fan I drilled a few small holes in the base of the RX casing to assist airflow through the unit. Hope this helps.
