For the last week or so, my HR20-100 has been over the temperature limit. Short of getting a replacement, what is the best solution for solving this problem? I've been able to cool it down with a small space heater set on fan setting - but was looking to a more permanent solution. I have not opened it up yet to see if for sure its the fan that it is in fact dead. It has screamed more than once, but has always quieted back down. Maybe tlast weeks was it's final one. I saw where an external USB fan was used to cool an overheating C31, and was wondering if anyone has had any success doing this on an ancient HR20? If so, what kind should I get? One that the HR20 would sit on, or should it blow in from one of the sides. Or should I just get a replacement internal fan? Current temp is 54°C - down from boot temp of 62°C.
