That's typical buyer's remorse setting in trust me. Wait until you at least have the receiver before you decide you hate it or not
I'm reading a lot about how incredibly hot these units get. Is this overblown, or simply people who aren't properly ventilating their receivers? Does the 2400 get hotter than a 3400?
These owners threads aren't good sources for accurate defect data on a product as it's more of a troubleshooting thread where operator error at times has its part as well as everyone's setup locations are different. Hard question to answer as it depends on where the receiver is kept along with type of content played, time it's played and level it's played at. Mines almost cool to the touch to barely warm as was my last Denon.
If a legitimate concern, to me it's a sign of poor engineering and build quality and I'll just return the Denon and opt for a cooler-running (allegedly) Yamaha from Costco.
Everybody's concerns here are considered legitimate but they are far from any proof of anything systemic as there's probably a few hundred people posting here for help and a minority of them are voicing temperature concerns(some of which were self inflicted IMHO.) Weigh that against the majority here who aren't having this issue along with the thousands of other owners world wide whom you would think would be flooding these threads with similar issues if systemic but they aren't. The Yamaha thread has it's own owners issues trust me. I've read every post for the last year or so. At least get it in your setup and see how things go first.
Adding an external fan is not an option; if Denon is so poorly designed that it requires an external cooling device, then I don't want it. I need this receiver to last at least five years, hopefully more.
The X4300H is my 2nd Denon receiver in the last 12 plus years. It's only the 2nd because the first one wouldn't die on me after those 12 plus years and is currently boxed up and sitting in my attic awaiting a new home or just as a backup receiver/amp. The HDMI boards are your biggest change in technologies between the 2 and the most likely to have issues but that's any device using HDMI these days. No guarantees but 5 years out of a 3 year warrantied product should be a safe bet.
It doesn't require an external cooling device it requires 4 to 5 inches of well ventilated space around the enclosures vents and decent airflow.
I'll store it in a cabinet that's closed in the front, open in the back, its shelf will be vented below the receiver, with several inches above the unit all clear.
You could invest in a cheap IR gun from Amazon for under $15 or so to save you from doing the hand test above the receivers enclosure and at least enable Auto Eco mode on the receiver to help about 10 degrees or so with no real loss in power to your speakers. The first recommend is not a must have(I don't) but the second isn't a bad idea(I do.)
I appreciate all the experience from you current owners. Thanks!
You're welcome. Having JD's the best experience in this thread
