Hi guys. Recently got the optical Rendu and it sounds amazing. I have a custom built power supply (built by Kenneth Lau) to power it. It’s a 7.5 v supply. I’ve heard it’s normal for the Rendu to run warm. Not too hot to touch but warm. I’m assuming this is normal. Just want reassurance as it really sounds wonderful.
Thanks!
What did you have prior? MicroRendus also run warm. I’d place a small DC fan nearby to run some low speed air across it. I use acinfinity.com USB fans for this.
For my setup I’m using a sonic transporter for my core. The optical Rendu connects to my DAC. The Rendu runs very warm.
From what I’m hearing, running warm is normal. So I think I’m good.
Thanks!
My oR runs quite warm as well. I measured ~111F on the surface.
You can take a DC fan and blow a cool stream of air across it. That would cool it significantly. I have two microRendus. They run warm to the touch, but not that hot. Make sure you have adequate clearance space or a fan.
They are designed to run at these temperatures (although lower V power supplies are recommended). No fan is needed, sit back and enjoy the music! If in any doubt, have a word with Sonore. Also they have their own discussion board now, an easy way to speak directly-
perfect for me…
111F is really too hot. They should not be above warm. A 7v supply will make it run cooler. A 9v supply will run it hotter. A DC fan on low speed circulates air, especially if the area is not well ventilated.
Mine was running hotter than comfortable, esp during this last heatwave, (and my other Sonore/Uptone low voltage devices) so I have some AC Infinity USB fans arriving today, one pair for the downstairs server closet and one for the opticalRendu and Sonore PS upstairs. I know they are designed to run that way, but I can’t help but think keeping them cooler might extend their life.
Cooler than Death Valley then… If it’s hotter than spec, have a word with the boys, send it back. Anyway, 8 degrees next Saturday morning in the UK.
You ever been to Death Valley? In August?
