-17, thats loud normally have it at -30 to -25. How do you check the temp?
Mine says 54/50 and the sound is barely on but the amps been on for an hour or so. + it's early so isn't warm yet. Problem is I only have 70mm clearance with my Alphason stand not the 200mm recommended. V: 0.00 and SEC: H. Whatever that means!?
Unless H is for hot? notice in the previous post the guy has N. Probably for normal.
The highest temperature reading I have seen on my 875 is around 67/61. However that is when I have pushed the 875 quite hard and have watched a movie at -10dB and it has been on for a few hours.
Now, after installing a 12cm fan on the top rear-back of the receiver - just resting above where the Reon chip is located - I get a max peak of 46/46 and the entire top area of the amp is cool to touch.
When I am gaming at around -30dB, it runs slightly cooler at 43/43.
Could you post a link to this fan. How much does one cost? does it just plug into the mains, or activated by temperature!?
So it's quite warm tonight and I have my 875 in, what was the old kitchen pantry, on the top of the rack with a good foot or so of clearance. The temp reading after a full film was 68/62, man it was hot!
As an aside I have been offered a Yamaha RXV-3800 at a really good price, do you think it's worth the swap as it won't cost me anything? Would appreciate any feedback.
I've now added another smaler fan to the rear right. I have now a 22cm fan to the left of the amp plus a 12cm fan at the rear.
Last night the temp stayed pretty stable at 46/50 after over 7 hours use.
It would also be intersting to know how much gap you have between the top of the amp and the next shelf above. Mine is only 11mm.
glenann, I have read that the performance of the Yamaha RXV-3800 is very good and it really does depend what your priorities are.
I don't think the Yamaha RXV-3800 would be an upgrade as such as they have very similar specifications but more of a sideways step.
If I was in your shoes, the only reason I would swap, is if I either didn't like the way the Onko 875 sounds, was really concerned about the heat (which is way I installed a fan) or you much prefer the look of the 3800.
BTW I tried the display/standby - tone combinatio but could not get a temp.
